138-617: The Consolidated B-24 Liberator is an American heavy bomber , designed by Consolidated Aircraft of San Diego, California . It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing . The wing gave
276-583: A United States Army Air Corps (USAAC) request in 1938 for Consolidated to produce the B-17 under license. After company executives including President Reuben Fleet visited the Boeing factory in Seattle, Washington , Consolidated decided instead to submit a more modern design of its own. The new Model 32 combined designer David R. Davis 's wing, a high-efficiency airfoil design created by unorthodox means, with
414-402: A B-29 style tail was fitted to the aircraft after its 25th flight but this did not resolve the problem and a Consolidated-designed 19.5 ft (5.9 m) vertical tail was added and first flown on the third XB-32, s/n 41-18336 on 3 November 1943. The first production aircraft was fitted with a B-29 vertical tail until the new Consolidated tail was available for installation. By 1944 testing of

An unusual four-panel set of all-metal, tambour-panel "roller-type" bomb bay doors, which operated very much like the movable enclosure of a rolltop desk , retracted into the fuselage. These types of doors created a minimum of aerodynamic drag to keep speed high over the target area; they also allowed
690-539: A few landed safely at RAF bases in Cyprus and some in Turkey, where they were interned. Only 33 were undamaged. Damage to the refineries was soon repaired and oil production actually increased. By October 1942, a new Ford Motor Company plant at Willow Run Michigan was assembling Liberators. Production reached a rate of over one an hour in 1944 helping the B-24 to become the most produced US aircraft of all time. It became
828-691: A lot to Sikorsky's ideas; of similar size, it used just two Rolls-Royce Eagle engines and could carry up to 2,000 lb (910 kg) of bombs. The O/100 was designed at the beginning of the war for the Royal Navy specifically to sink the German High Seas Fleet in Kiel: the Navy called for “a bloody paralyser of an aircraft” Entering service in late 1916 and based near Dunkirk in France, it
966-491: A navigational error which alerted the defenders and protracted the bomb run from the initial point. The 44th destroyed both of its assigned targets, but lost 11 of its 37 bombers and their crews. Colonel Leon W. Johnson , the 44th's commander, was awarded the Medal of Honor for his leadership, as was Col. John Riley "Killer" Kane , commander of the 98th Bomb Group. Kane and Johnson survived the mission but three other recipients of

The Liberators made a significant contribution to Allied victory in the Battle of the Atlantic against German U-boats . Aircraft had the ability to undertake surprise air attacks against surfaced submarines. Liberators assigned to the RAF's Coastal Command in 1941, offensively to patrol against submarines in

Initially, defence against air attack was poor, but by May 19, 1918, when 38 Gothas attacked London, six were shot down and another crashed on landing. German aircraft companies also built a number of giant bombers, collectively known as the Riesenflugzeug . Most were produced in very small numbers from 1917 onwards and several never entered service. The most numerous were
1518-468: A second B-32 missed flak positions with its 260 lb (120 kg) fragmentation bombs. The last mission was flown on 25 June against bridges near Kiirun on Formosa. The test crews were impressed with its unique reversible-pitch inboard propellers and the Davis wing, which gave it excellent landing performance. However, they found a number of faults: the cockpit was noisy and had a poor instrument layout,

On 29 May 1945, the first of four combat missions by the B-32 was flown against a supply depot at Antatet in the Philippines , followed by two B-32s dropping 16 2,000 lb (910 kg) bombs on a sugar mill at Taito, Formosa , on 15 June. On 22 June, a B-32 bombed an alcohol plant at Heito, Formosa, with 500 lb (230 kg) bombs, but
1794-517: A shoulder-mounted high aspect ratio Davis wing. This wing was highly efficient allowing a relatively high airspeed and long range. Compared to the B-17, it had a 6 feet (1.8 m) larger wingspan but a lower wing area. This gave the B-24 a 35-percent higher wing loading . The relatively thick wing held the promise of increased tankage while delivering increased lift and speed, but it became unpleasant to fly when committed to heavier loadings as experienced at high altitude and in bad weather. The Davis wing
1932-515: A squadron of 10 was bombing German positions on the Eastern Front and by summer 1916 there were twenty. It was well-armed with nine machine guns, including a tail gun and initially was immune to German and Austro-Hungarian air attack. The Sikorsky bomber had a wingspan just a few feet shorter than that of a World War II Avro Lancaster , while being able to carry a bomb load of only 3% of the later aircraft. The Handley Page Type O /100 owed

Within weeks, the First Provisional Bombardment Group formed from the remnants of the Halverson and China detachments. This unit then was formalized as the 376th Bombardment Group, Heavy, and along with the 98th BG formed
2208-426: A top-mounted turret, a tail turret and single machine guns located in the waist and in the glazed nose. The B-24D initially featured upper, belly and tail turrets, plus swiveling single guns in the waist and on either side of the nose. The belly turret was a periscopically sighted Bendix model. The turret proved unsatisfactory and was soon replaced by a tunnel gun, which was itself omitted. Later D models were fitted with
2346-493: A total of 30 flights before the second XB-32, s/n 41-142, finally flew on 2 July 1943. This aircraft had a traditional stepped cockpit canopy. Upon examination and testing, the USAAF recommended a large number of changes that included more conventional gun stations. The pressurization system had problems which were never solved and so the role of the aircraft was changed to operating at low to medium altitude. This decision meant that
2484-466: A war. This was certainly vindicated by the firebombing of Japanese cities and the two atomic bombs dropped on Hiroshima and Nagasaki in August 1945, as Japan's fragile housing and cottage industry made themselves easily vulnerable to attack, thus completely destroying Japanese industrial production (see Air Raids on Japan ). It was less evident that it held true for the bombing of Germany. During
2622-580: A wide variety of roles. At approximately 18,500 units – including 8,685 manufactured by Ford Motor Company – it holds records as the world's most produced bomber, heavy bomber, multi-engine aircraft, and American military aircraft in history. The B-24 was used extensively in World War II where it served in every branch of the American armed forces, as well as several Allied air forces and navies. It saw use in every theater of operations. Along with
2760-665: The Allies on August 15, and the Japanese government subsequently signed the official instrument of surrender on September 2, 1945. After World War II, the name strategic bomber came into use, for aircraft that could carry aircraft ordnances over long distances behind enemy lines. They were supplemented by smaller fighter-bombers with less range and lighter bomb load, for tactical strikes. Later these were called strike fighters , attack aircraft and multirole combat aircraft . When North Korea attacked South Korea in 1950

The Vimy's intended use was to bomb industrial and railway targets in western Germany, which it could reach with its range of 900 miles (1,400 km) and a bomb load of just over a ton. The Vickers Vimy is best known as the aircraft that made the first Atlantic crossing from St John's Newfoundland to Clifden in Ireland piloted by the Englishman John Alcock and navigated by Scot Arthur Whitten Brown on June 14, 1919.

#17327726308483036-708: The B-1 , B-52 and B-2 have been retained for the role of carpet bombing in several conflicts. The most prolific example (in terms of total bomb tonnage) is the U.S. Air Force B-52 Stratofortress during the 1960s–early 1970s Vietnam War era, in Operation Menu , Operation Freedom Deal , and Operation Linebacker II . In 1987 the Soviet Tu-160 —the heaviest supersonic bomber/aircraft currently in active service—entered service; it can carry twelve long-range cruise missiles. The 2010 New START agreement between
3174-701: The B-29 (1944) delivered payloads in excess of 20,000 pounds (9,100 kg) and had a range of 3,250 miles (5,230 km). By the late 1950s, the jet -powered Boeing B-52 Stratofortress , travelling at speeds of up to 650 miles per hour (1,050 km/h) (more than double that of a Lancaster), could deliver a payload of 70,000 pounds (32,000 kg), over a combat radius of 4,480 miles (7,210 km). During World War II, mass production techniques made available large, long-range heavy bombers in such quantities as to allow strategic bombing campaigns to be developed and employed. This culminated in August 1945, when B-29s of
3312-693: The Douglas C-47 Skytrain . By the end of World War II, the technological breakthroughs of the Boeing B-29 Superfortress and other modern types had surpassed the bombers that served from the start of the war. The B-24 was rapidly phased out of U.S. service, although the PB4Y-2 Privateer maritime patrol derivative carried on in service with the U.S. Navy in the Korean War . The Liberator originated from

After Wever's death, Ernst Udet , development director at the Air Ministry steered the Luftwaffe towards dive bombers instead. When Britain and France declared war on Germany in September 1939, the RAF had no heavy bomber yet in service; heavy bomber designs had started in 1936 and ordered in 1938. The Handley Page Halifax and Avro Lancaster both originated as twin-engine "medium" bombers, but were rapidly redesigned for four Rolls-Royce Merlin engines and rushed into service once
3588-538: The Junkers Ju 88 . Heavy bombers still needed defensive armament for protection, even at night. The Stirling's low operational ceiling of just 12,000 ft (3,700 m)—also caused by the thick wing—meant that it was usually picked on by night fighters; within five months, 67 of the 84 aircraft in service had been lost. The bomb bay layout limited the size and types of bombs carried and it was relegated to secondary duties such as tug and paratrooper transport. Due to
3726-464: The Leigh Light , not a single enemy submarine had been sunk in over five months, but in combination with radar, it was so overwhelmingly effective that many German submarine crews chose to surface during the day so that they could at least see the aircraft attacking them and have a chance to fire their anti-aircraft weaponry in defense. These Liberators operated from both sides of the Atlantic with
3864-852: The Middle East in early 1942. While RAF Bomber Command did not use B-24s as strategic bombers over mainland North West Europe , No. 223 Squadron RAF , one of Bomber Command's 100 (Bomber Support) Group squadrons, used 20 Liberator VIs to carry electronic jamming equipment to counter German radar. In October 1944, two RAF Liberator squadrons (357 and 358) were deployed to Jessore , India, in support of British SAS, American OSS and French SIS underground operations throughout SE Asia. The aircraft were stripped of most armaments to allow for fuel for up to 26-hour return flights such as Jessore to Singapore. Liberators were also used as anti-submarine patrol aircraft by RAF Coastal Command. RAF Liberators were operated as bombers from India by SEAC and would have been

An early raid on Rouen-Sotteville rail yards in Brittany on August 17, 1942, required four Spitfire squadrons outbound and five more for the return trip. The USAAF chose to attack aircraft factories and component plants. On August 17, 1943, 230 Fortresses attacked a ball-bearing plant in Schweinfurt and again two months later, with 291 bombers, in

The arrival of nuclear weapons and guided missiles permanently changed the nature of military aviation and strategy . After the 1950s intercontinental ballistic missiles and ballistic missile submarines began to supersede heavy bombers in the strategic nuclear role. Along with the emergence of more accurate precision-guided munitions ("smart bombs") and nuclear -armed missiles , which could be carried and delivered by smaller aircraft, these technological advancements eclipsed

On 17 August, the B-32s were intercepted by Japanese fighters. During the two-hour engagement, the Dominators suffered only minor damage and none of their crew were injured. "Though the B-32 gunners later claimed to have damaged one fighter and 'probably destroyed' two others, surviving Japanese records list no losses for that day or next." Based on

The RAF found, as did the US, that global war increased the need for air transports and early-type bombers and seaplanes were converted or completed as cargo carriers and transports. LB-30As were assigned to transatlantic flights by RAF Ferry Command , between Canada and Prestwick , Scotland. The first Liberators in British service were ex-USAAF YB-24s converted to Liberator GR Is (USAAF designation: LB-30A). The aircraft were all modified for logistic use in Montreal . Changes included

In the Pacific, to simplify logistics and to take advantage of its longer range, the B-24 (and its twin, the U.S. Navy PB4Y) was the chosen standard heavy bomber. By mid-1943, the shorter-range B-17 was phased out. The Liberators which had served early in the war in the Pacific continued the efforts from the Philippines, Australia, Espiritu Santo, Guadalcanal, Hawaii, and Midway Island.

This model introduced self-sealing fuel tanks, a 2 ft 7 in (79 cm) plug in the forward fuselage to create more space for crew members and, more vitally, ever more equipment such as ASV Mark II radar (anticipated early in the Liberator's development when Reuben Fleet told the engineering team he had a gut feeling

The maximum takeoff weight was one of the highest of the period. The new design would be the first American heavy bomber in production to use tricycle landing gear – the North American B-25 Mitchell medium bomber's predecessor,

Due to its range, it proved useful in bombing operations in the Pacific , including the bombing of Japan . Long-range anti-submarine Liberators played an instrumental role in closing the Mid-Atlantic gap in the Battle of the Atlantic . The C-87 transport derivative served as a longer range, higher capacity counterpart to
6210-513: The B-17. The specification was written such that the Model 32 would automatically be the winning design. The program was run under the umbrella group, "Project A", an Air Corps requirement for an intercontinental bomber that had been conceived in the mid-1930s. Although the B-24 did not meet Project A goals, it was a step in that direction. Project A led to the development of the Boeing B-29 and Consolidated's own B-32 and B-36 . The B-24 had

Even this extra firepower, which increased empty weight by 20% and required more powerful versions of the Wright Cyclone engine, was insufficient to prevent serious losses in daylight. Escort fighters were needed but the RAF interceptors such as
6486-479: The B-24 sensitive to weight distribution. Hendrix claimed that a lightly loaded B-24 could out-turn a P-38 Lightning. A heavily loaded B-24 was difficult to fly at speeds of less than 160 mph (260 km/h). The B-24's controls were heavy, especially if the control rigging was not properly tensioned. B-24s leaked fuel. Crews flew with the bomb bay doors slightly open to dissipate potentially explosive fumes. Hendrix did not permit smoking on his B-24, even though he
6624-791: The B-24 was the predominant bomber of U.S. Strategic Air Forces (USSTAF) formerly the Eighth Air Force in the Combined Bomber Offensive against Germany, forming nearly half of its heavy bomber strength in the ETO prior to August and most of the Italian-based force. Thousands of B-24s flying from bases in Europe dropped hundreds of thousands of tons of high explosive and incendiary bombs on German military, industrial, and civilian targets.

One major failure of the prototype was that it failed to meet the top speed requirements specified in the contract. As built, the XB-24 top speed was only 273 mph instead of the specified 311 mph. As a result, the mechanically supercharged Pratt & Whitney R-1830-33s were replaced with

9246-443: The aircraft to be unreliable, under-powered and hastened its withdrawal from service. Reaching squadrons early in 1942, the redesigned bomber with four Merlin engines and longer wings was renamed Avro Lancaster ; it could deliver a 14,000 lb (6,400 kg) load of bombs or up to 22,000 lb (10,000 kg) with special modifications. The Lancaster's bomb bay was undivided, so that bombs of extraordinary size and weight such as
9384-470: The bomb bays to be opened while on the ground since the low ground clearance prevented the use of normal bomb bay doors. The occasional need during a mission for crewmen to move from fore to aft within the B-24's fuselage over the narrow catwalk was a drawback shared with other bomber designs. The Liberator carried a crew of up to ten. The pilot and co-pilot sat alongside each other in a well-glazed cockpit. The navigator and bombardier — who could also double as
9522-419: The bombardier's clear nose glazing as "cheek" positions, or midway along the rear fuselage sides as "waist" positions. U.S. bombers carried .50 caliber machine gun , and dorsal (spine/top of aircraft) and ventral (belly/bottom of aircraft) guns with powered turrets . All of these machine guns could defend against attack when beyond the range of fighter escort; eventually, a total of 13 machine guns were fitted in
9660-561: The bombardier's vision was limited, the aircraft was overweight, and the nacelle design resulted in frequent engine fires (a deficiency shared with the B-29 Superfortress). However, the testing missions were mostly successful. In July 1945, the 386th Bomb Squadron completed its transition to the B-32, flying six more combat missions before the war ended. On 13 August, the 386th BS moved from Luzon to Yontan Airfield on Okinawa and flew mostly photographic reconnaissance missions. On 15 August, Japan surrendered (documents signed 2 September), and
9798-608: The bombers were restricted to night interdiction and concentrated on destroying supply routes, including the bridges over the Yalu river into China. By the 1960s, manned heavy bombers could not match the intercontinental ballistic missile in the strategic nuclear role. More accurate precision-guided munitions ("smart bombs"), nuclear -armed missiles or bombs were able to be carried by smaller aircraft such as fighter-bombers and multirole fighters . Despite these technological innovations and new capabilities of other contemporary military aircraft , large strategic bombers such as
9936-546: The bombers were then switched to low-level, nighttime incendiary attacks for which they had not originally been designed (one variant, the B-29B was specially modified for low altitude night missions by removal of armament and other equipment). Japan burned furiously from the B-29 incendiary raids. On August 6, 1945, B-29 Enola Gay dropped an atomic bomb on Hiroshima. Three days later, B-29 Bockscar dropped another on Nagasaki. The war ended when Japan announced its surrender to
10074-528: The damage, the Dominator returned to Okinawa. However, the incident precipitated the removal of propellers from all Japanese fighters as per the terms of the ceasefire agreement, beginning 19 August 1945. The last B-32 combat photo reconnaissance mission was completed on 28 August, during which two B-32s were destroyed in separate accidents, with 15 of the 26 crewmen killed. On 30 August, the 386th Bomb Squadron stood down from operations. Production contracts of
10212-592: The deferment. Lindell Hendrix, later a test pilot for Republic Aviation , flew B-24s for the Eighth Air Force. Hendrix preferred the B-24 to the B-17. In Eighth Air Force combat configuration, the aircraft carried 8,000 pounds (3,600 kg) of bombs. It could manage an altitude of no more than 25,000 ft (7,600 m), three or four thousand feet less than a B-17, but it flew 10–15 mph (16–24 km/h) faster. Its lower altitude made it more vulnerable to flak. Hendrix figured that Germans understood it
10350-542: The eastern Atlantic Ocean , produced immediate results. The introduction of Very Long Range (VLR) Liberators vastly increased the reach of the UK's maritime reconnaissance force, closing the Mid Atlantic Gap where a lack of air cover had allowed U-boats to operate without risk of aerial attack. For 12 months, No. 120 Squadron RAF of Coastal Command with its handful of worn and modified early model Liberators supplied
10488-420: The end of 1939. The design was simple in concept but, nevertheless, advanced for its time. Consolidated incorporated innovative features such as a tricycle landing gear and Davis wing. Compared to the B-17, the proposed Model 32 had a shorter fuselage and 25% less wing area, but had a 6 ft (1.8 m) greater wingspan and a substantially larger carrying capacity, as well as a distinctive twin tail. Whereas
10626-526: The end of the war. The single fin did appear in production on the PB4Y Privateer derivative. The B-24's spacious, slab-sided fuselage (which earned the aircraft the nickname "Flying Boxcar ") was built around two central bomb bays that could accommodate up to 8,000 pounds (3,600 kg) of ordnance in each compartment (but rarely did, as this decreased range and altitude). The forward and aft bomb bay compartments were further split longitudinally with
10764-635: The extant orders of the B-32 were canceled shortly thereafter and only 118 B-32 airframes of all types were built. The engineering development of the B-29 had been underway since mid-1938 when, in June 1940, the United States Army Air Corps requested a similar design from the Consolidated Aircraft Company in case of development difficulties with the B-29. The Model 33 on which Consolidated based its proposal
10902-450: The fighter pilots could not bear to see American bombers flying serenely over a devastated Tokyo. The B-32 Dominator Hobo Queen II (s/n 42-108532) was flying at 20,000 ft (6,100 m) when the Japanese fighters took off and received no significant damage. Hobo Queen II claimed two Zeros destroyed in the action as well as a probable Shiden-Kai. The other Dominator was flying 10,000 ft (3,000 m) below Hobo Queen II when
11040-514: The fighters took off. The fighters heavily damaged that Dominator, initially wounding the dorsal gunner and then seriously wounding two other members. Photographer Staff Sergeant Joseph Lacharite was wounded in the legs (his recovery spanned several years). Sergeant Anthony Marchione, a photographer's assistant, helped Lacharite and then was fatally wounded himself. Marchione was the last American to die in air combat in World War II. Despite
11178-404: The flight. Over Japan, a formation of 14 A6M Zeros and three N1K2-J Shiden-Kai (George) fighters (apparently mis-identified as Ki-44 Tojos by the American crews ) attacked the remaining two U.S. aircraft. Saburō Sakai , a Japanese ace, said later that there was concern that the Dominators were attacking. Another Japanese ace, Sadamu Komachi , stated in a 1978 Japanese magazine article that
11316-556: The heavy bomber's once-central role in strategic warfare by the late 20th century. Heavy bombers have, nevertheless, been used to deliver conventional weapons in several regional conflicts since World War II (for example, B-52s in the Vietnam War ). Heavy bombers are now operated only by the air forces of the United States, Russia and China. They serve in both strategic and tactical bombing roles. The first heavy bomber
11454-497: The importance of weight and aerodynamic efficiency. Thus naval patrol often omitted top, belly and nose turrets. Some were fitted with a belly pack containing fixed, forward-facing cannon. The U.S. Army Air Corps awarded a contract for the prototype XB-24 in March 1939, with the requirement that one example should be ready before the end of the year. Consolidated finished the prototype and had it ready for its first flight two days before
11592-579: The initial design suitable for bombing and it was first used on a variety of VIP transport and maritime patrol missions. Its long range, however, persuaded the USAAF to send 177 Liberators from Benghazi in Libya to bomb the Romanian oilfields on August 1, 1943, in Operation Tidal Wave . Due to navigational errors and alerted German flak batteries and fighters, only half returned to base although
11730-411: The last American to die in air combat in World War II. It was developed by Consolidated Aircraft in parallel with the Boeing B-29 Superfortress as a fallback design should the B-29 prove unsuccessful. The B-32 reached units in the Pacific only in mid-May 1945, and subsequently saw only limited combat operations against Japanese targets before the formal end of the war on 2 September 1945. Most of
11868-609: The last surviving Dominator, B-32-1-CF #42-108474, was written off and destroyed in 1949. A total of 300 B-32s ordered, 118 delivered, 130 flyable, 170 cancelled, orders for a further 1,099 B-32-CFs and 499 B-32-COs were cancelled after VJ-Day. No examples of a B-32 remain today. The XB-32 (AAF Ser. No. 41-18336) survived until 1952 as a ground instructional airframe for fire fighting training at McClellan Air Force Base. Others were written off after suffering major damage in operational accidents. Excess inventories were flown either to Walnut Ridge Army Airfield , Arkansas, to be scrapped by
12006-556: The logistics (including transport of fuel for the B-29 fleet over the Himalayan range ) of flying from these remote, primitive airfields were complicated and costly. The island of Saipan in the Marianas was assaulted to provide Pacific air bases from which to bomb Japanese cities . Initial high-level, daylight bombing raids using high-explosive bombs on Japanese cities with their wood and paper houses produced disappointing results;
12144-420: The nose turret. The waist gun hatches were provided with doors. The ball turret was required to be retractable for ground clearance when preparing to land as well as for greater aerodynamic efficiency. The tail gunner's powered twin-gun turret was located at the end of the tail, behind the tailplane. The B-24 featured a tricycle undercarriage, the first American bomber to do so, with the main gear extending out of
12282-423: The nose was too short). The Mark II was the first Liberator to be equipped with powered turrets, one plane having them installed before leaving San Diego, the remainder having them installed in the field: four Browning Boulton Paul A-type Mk IV with 600 rounds of .303 in the dorsal position; and a Boulton Paul E-type Mk II with 2200 rounds in the tail (later increased to 2500 rounds), supplemented by pairs of guns at
12420-734: The nucleus of the IX Bomber Command of the Ninth Air Force , operating from Africa until absorbed into the Twelfth Air Force briefly, and then the Fifteenth Air Force , operating from Italy. The Ninth Air Force moved to England in late 1943. This was a major component of the USSTAF and took a major role in strategic bombing. Fifteen of the 15th AF's 21 bombardment groups flew B-24s. For much of 1944,
12558-524: The only air cover for convoys in the Atlantic Gap, the Liberator being the only airplane with sufficient range. The VLR Liberators sacrificed some armor and often gun turrets to save weight, while carrying extra aviation gasoline in their bomb-bay tanks. Liberators were equipped with ASV Mk. II radar , which together with the Leigh light , gave them the ability to hunt U-boats by day and by night. Before
12696-399: The pilots, facing sideways and sometimes doubled as a waist gunner. The flight engineer sat adjacent to the radio operator behind the pilots; he operated the upper gun turret (when fitted), located just behind the cockpit and in front of the wing. Up to four crew members could be located in the waist, operating waist guns, a retractable lower ball turret gun, and a tail gun turret matching
12834-550: The policy of staying on the surface to fight, rather than submerging and risking being sunk by aerial weapons such as rockets, gunfire, torpedoes and depth charges from the bombers. American Liberators flew from Nova Scotia , Greenland , the Azores, Bermuda , the Bahamas , Puerto Rico , Cuba , Panama, Trinidad , Ascension Island and from wherever else they could fly far out over the Atlantic. The sudden and decisive turning of
12972-514: The powerplant seriously delayed the B-29's operational service debut. The aircraft had four remotely operated twin-gun turrets on its fuselage , controlled through an analog computer sighting system; the operator could use any of a trio of Perspex ball stations. Only the tail gunner manually controlled his gun turret station in the rear of the airplane. B-29s were initially deployed to bases in India and China, from which they could reach Japan; but
13110-597: The pressurization system was easily eliminated from production aircraft. Problems with the remote-controlled gun turrets were never solved and the armament on production aircraft was changed to 10 .50 caliber machine guns in manually operated turrets: Sperry A-17 turrets in the nose and tail, two Martin A-3F-A dorsal turrets, and one Sperry A-13-A ball turret. The bomb load was increased by 4,000 pounds (1,800 kg) to 20,000 pounds (9,100 kg). The second XB-32 continued to have stability problems. In an attempt to resolve this
13248-471: The removal of all armament, provision for passenger seating, a revised cabin oxygen and heating system . Ferry Command's Atlantic Return Ferry Service flew civilian ferry pilots, who had delivered aircraft to the UK, back to North America. The most important role, however, for the first batch of the Liberator GR Is was in service with RAF Coastal Command on anti-submarine patrols in the Battle of
13386-479: The retractable Sperry ball turret. The B-24H saw the replacement of the glazed 'green house' nose with a nose turret, which reduced the B-24s vulnerability to head-on attacks. The bombsight was located below the turret. Long-range naval patrol versions often carried a light defensive armament. Being on long-distance patrols, they generally flew outside the range of enemy fighters. Also, the necessity of range increased
13524-443: The right wing. The inboard propeller windmilled to a stop. And then, suddenly, the whole wing broke off. At an altitude of 900 metres there was a tremendous explosion. The bomber had disintegrated. The blazing wreckage landed just outside Bad Zwischenahn airfield." A total of 177 B-24s carried out the famous second attack on Ploiești ( Operation Tidal Wave ) on 1 August 1943. This was the B-24's most costly mission. In late June 1943,
13662-412: The second half of the 20th century, heavy bombers were largely superseded by strategic bombers , which were often even larger in size, had much longer ranges and were capable of delivering nuclear bombs . Because of advances in aircraft design and engineering — especially in powerplants and aerodynamics — the size of payloads carried by heavy bombers has increased at rates greater than increases in
13800-587: The size of their airframes. The largest bombers of World War I , the Zeppelin-Staaken Riesenflugzeuge of Germany, could carry a payload of up to 4,400 pounds (2,000 kg) of bombs; by the latter half of World War II , the Avro Lancaster (introduced in 1942) routinely delivered payloads of 14,000 pounds (6,400 kg) (and sometimes up to 22,000 lb (10,000 kg)) and had a range of 2,530 miles (4,070 km), while
13938-505: The specialized squadrons were the 20th RS (RCM), 36th BS (RCM), 406th NLS, 63rd BS (SB) SeaHawks, 373rdBS (LAB) and 868th BS (SB) Snoopers. The 36th Bombardment Squadron was the Eighth Air Force's only electronic warfare squadron using specially equipped B-24s to jam German VHF communications during large Eighth Air Force daylight raids. In addition, the 36th BS flew night missions with RAF Bomber Command's own electronic warfare unit 100 Group at RAF Sculthorpe . Radar Counter Measures (RCM)
14076-570: The standard heavy bomber in the Pacific and the only one used by the RAAF. The SAAF used Liberators to drop weapons and ammunition during the Warsaw Uprising in 1944. The Avro Manchester was a twin-engine bomber powered by the ambitious 24-cylinder Rolls-Royce Vulture , but was rapidly redesigned for four Rolls-Royce Merlin engines due to technical problems with the Vulture which caused
14214-665: The technical problems of the larger Rolls-Royce Vulture emerged in the Avro Manchester . The Halifax joined squadrons in November 1940 and flew its first raid against Le Havre on the night of 11–12 March 1941. British heavy bomber designs often had three gun turrets with a total of 8 machine guns . In January 1941, the Short Stirling reached operational status and first combat missions were flown in February. It
14352-440: The three B-24 Liberator groups of the 8th Air Force were sent to North Africa on temporary duty with the 9th Air Force: the 44th Bomb Group joined the 93rd and the 389th Bomb Groups. These three units then joined the two 9th Air Force B-24 Liberator groups for low-level attack on the Romanian oil complex at Ploiești. This daring assault by high-altitude bombers at treetop level was a costly success. The attack became disorganized after
14490-516: The three prototypes permitted the AAF to place orders for over 1,500 B-32s. The first production aircraft was delivered on 19 September 1944, by which time the B-29 was in combat in China . The first B-32 crashed on the same day it was delivered when the nose wheel collapsed on landing. Beginning on 27 January 1945, 40 B-32A-5, -10 and -15 aircraft were delivered as unarmed TB-32-CF crew trainers. Originally,
14628-473: The time, despite neutrality, was that American requirements could be deferred while its Allies could immediately put US production into the war effort. The added advantage was the American types could be assessed in the European war zone earlier. Thus the first six YB-24 were released for direct purchase under CAC contract # F-677 on 9 November 1940. These aircraft were redesignated LB-30A . The seventh aircraft
14766-437: The use of a single vertical fin. The single fin was tested by Ford on a single B-24ST variant and an experimental XB-24K: it was found to improve handling. However, all Liberators were produced with twin oval fins, with the exception of eight preproduction B-24N aircraft. The B-24N was intended as a major production variant featuring a single tail. Over 5000 orders for this version were placed in 1945, but they were cancelled due to
14904-599: The waist position, a single gun in the nose and another in the belly, for a total of fourteen guns. The maximum take-off weight was slightly raised to 64,250 pounds, the maximum altitude lifted from 21,200 to 24,000 feet but the maximum speed was reduced to 263 mph, largely as a result of increased drag. The Liberator II (referred to as the LB-30A by the USAAF) were divided between Coastal Command , Bomber Command , and British Overseas Airways Corporation (BOAC). Both BOAC and
15042-530: The war, German industrial production actually increased , despite a sustained Allied bombing campaign. As the German Luftwaffe 's main task was to support the army, it never developed a successful heavy bomber. The prime proponent of strategic bombing, Luftwaffe Chief of Staff General Walther Wever , died in an air crash in 1936 on the very day that the specification for the Ural bomber (later won by
15180-469: The war, bombers continually managed to strike their targets, but suffered unacceptable losses in the absence of careful planning and escort fighters . Only the later de Havilland Mosquito light bomber was fast enough to evade fighters. Heavy bombers needed defensive armament for protection, which reduced their effective bomb payload. The second tenet was that strategic bombing of industrial capacity, power generation, oil refineries, and coal mines could win
15318-512: The wars, aviation opinion fixed on two tenets. The first was that “ the bomber will always get through .” The speed advantage of biplane fighters over bombers was insignificant, and it was believed that they would never catch them. Furthermore, there was no effective method of detecting incoming bombers at sufficiently long range to scramble fighters on an interception course. In practice, a combination of new radar technology and advances in monoplane fighter design eroded this disadvantage. Throughout
15456-605: The way to the target and back. Losses were reduced to 247 out of 3,500 sorties, still devastating but accepted at the time. The Consolidated B-24 Liberator and later version of the Fortress carried even more extensive defensive armament fitted into Sperry ball turrets . This was a superb defensive weapon that rotated a full 360 degrees horizontally with a 90-degree elevation. Its twin M2 Browning machine guns had an effective range of 1,000 yards (910 m). The Liberator
15594-412: The wing on long, single-oleo strut legs. It used differential braking and differential thrust for ground steering, which made taxiing difficult. The defensive armament of the B-24 varied from transport variants, which were usually unarmed, to bombers armed with up to ten .50 caliber (12.7 mm) M2 Browning machine guns located in turrets and waist gun positions. Early model Liberators were fitted with
15732-421: The wings outboard of the propellers. The turrets were remotely controlled from periscopic sights in aiming stations inside the aircraft. The sights were coordinated by a sophisticated analog computer system developed by Sperry Gyroscope Company . On 17 March 1943, the initial contract was signed for 300 B-32-CFs but development problems continued. On 10 May 1943, the first XB-32 crashed on takeoff after making
15870-511: Was Torpex torpedo explosive, it was developed specifically to sink the Tirpitz which was moored in Trondheim fjord behind torpedo nets. Development delays in the 'bouncing bomb' meant that another Barnes Wallis invention, the 5-ton Tallboy was deployed instead; two Tallboys dropped by Avro Lancasters from 25,000 ft (7,600 m) altitude hit at near- supersonic speed and capsized
16008-607: Was 45.5 bomb groups in June 1944. Additionally, the Liberator equipped a number of independent squadrons in a variety of special combat roles. The cargo versions, C-87 and C-109 tanker, further increased its overseas presence, especially in Asia in support of the XX Bomber Command air offensive against Japan. So vital was the need for long-range operations, that at first USAAF used the type as transports. The sole B-24 in Hawaii
16146-482: Was a backlog of orders amounting to $ 680m, of which $ 400m was foreign orders, US official statistics indicating tooling, plant and expansion advanced the previously anticipated volume of US aircraft production by up to a year. A consequence of the British orders went beyond requests for specific modifications: as the RAF accepted some designs while rejecting others, American production was – to some extent – re-directed along specific lines that accorded with British doctrine,
16284-533: Was a smoker. Chain smoker "Tex" Thornton , then in command of the US Army Air Corps' Statistical Control, flew across the Atlantic in a B-24, and was not permitted to smoke. Thornton's Statistical Control group demonstrated that Eighth Air Force B-24s were taking lower casualties than B-17s because they were being given shorter, safer missions. The B-17s actually delivered more bombs to the target than B-24s. The first British Liberators had been ordered by
16422-507: Was also more susceptible to ice formation than contemporary designs, causing distortions of the aerofoil section and resulting in the loss of lift, with unpleasant experiences drawing such comments as, "The Davis wing won't hold enough ice to chill your drink". The wing was also more susceptible to damage than the B-17's wing, making the aircraft less able to absorb battle damage. The wing carried four supercharged Pratt & Whitney R-1830-35 Twin Wasp engines mounted in cowlings borrowed from
16560-544: Was based on the successful Short Sunderland flying boat and shared its Bristol Hercules radial engines, wing, and cockpit with a new fuselage. It carried up to 14,000 lb (6,400 kg) of bombs—almost twice the load of a Boeing B-17 Flying Fortress —but over just a 300-mile (480 km) radius. Due to its thick, short wing it was able to out-turn the main German night fighters, the Messerschmitt Bf 110 and
16698-745: Was clear that the B-17C model was not combat ready and that its five machine guns provided inadequate protection. Combat feedback enabled Boeing engineers to improve the aircraft; when the first model B-17E began operating from English airfields in July 1942, it had many more defensive gun positions including a vitally important tail gunner. Eventually, U.S. heavy bomber designs, optimized for formation flying, had 10 or more machine guns and/or cannons in both powered turrets and manually operated flexible mounts to deliver protective arcs of fire. These guns were located in tail turrets , side gun ports either just behind
16836-464: Was code-named Carpet, however, this should not be confused with agent and supply drops, code-named "Carpetbaggers". Heavy bomber Heavy bombers are bomber aircraft capable of delivering the largest payload of air-to-ground weaponry (usually bombs ) and longest range ( takeoff to landing ) of their era. Archetypal heavy bombers have therefore usually been among the largest and most powerful military aircraft at any point in time. In
16974-678: Was designed as an airliner . Igor Sikorsky , an engineer educated in St Petersburg, but born in Kiev of Polish-Russian ancestry designed the Sikorsky Ilya Muromets to fly between his birthplace and his new home. It did so briefly until August 1914, when the Russo-Balt wagon factory converted to a bomber version, with British Sunbeam Crusader V8 engines in place of the German ones in the passenger plane. By December 1914
17112-447: Was destroyed by Grand Slams creating an earthquake effect, which shook the foundations. The Boeing B-29 Superfortress was a development of the Fortress, but a larger design with four Wright R-3350 Duplex-Cyclone engines of much greater power, enabling it to fly higher, faster, further and with a bigger bomb load. The mammoth new Wright radial engines were susceptible to overheating if anything malfunctioned, and technical problems with
17250-561: Was destroyed by the Japanese attack on Pearl Harbor on 7 December 1941. It had been sent to the Central Pacific for a very long-range reconnaissance mission that was preempted by the Japanese attack. The first USAAF Liberators to carry out combat missions were 12 repossessed LB-30s deployed to Java with the 11th Bombardment Squadron ( 7th Bombardment Group ) that flew their first combat mission in mid-January. Two were shot up by Japanese fighters, but both managed to land safely. One
17388-412: Was easier to hit, and that it carried more bombs. It was necessary when flying the B-24, to get "on step". This meant climbing to about 500 ft (150 m) above cruise altitude, levelling off, achieving a cruise speed of 165–170 mph (266–274 km/h), then descending to assigned altitude. Failing to do this meant that the B-24 flew slightly nose high, and it used more fuel. The Davis wing made
17526-517: Was one of the first two heavy bombardment groups flying the B-24 with the 8th Air Force in the fall/winter air campaigns in the European Theater of Operations. The 44th Bomb Group flew the first of its 344 combat missions against the Axis powers in World War II on 7 November 1942. The first B-24 loss over German territory occurred on 26 February 1943. Earlier in the war, both the Luftwaffe and
17664-546: Was similar to the B-24 Liberator . Like the B-24 it was originally designed with a twin tail and a large Davis wing , but with a longer, rounder fuselage and a rounded nose. The powerplants were to be the same quartet of eighteen-cylinder, 2,200 horsepower (1,600 kW) Wright Duplex-Cyclones , as specified for B-29s. The aircraft was designed to be pressurized, and have remote-controlled retractable gun turrets with fourteen .50 in (12.7 mm) machine guns. It
17802-431: Was six months behind schedule, the aircraft making its first flight on 7 September 1942. Due to problems with the pressurization system, the gun turrets and landing gear doors, these items were omitted on the first prototype. The aircraft had R-3350-13 engines inboard and R-3350-21s outboard, with all four powerplants driving three-bladed propellers. The XB-32 had persistent problems with engine oil leaks and poor cooling, but
17940-449: Was the only reporter assigned to a B-24-equipped group, the 44th Bomb Group. He flew in B-24 41-23777 ("Maisey") on Mission No. 37 to Bremen, Germany . Intercepted just short of the target, the B-24 came under attack from JG 1 's Messerschmitt Bf 109s . Leutnant Heinz Knoke (who finished the war with 31 kills) shot down the Liberator. Post and all but two of the 11 men aboard were killed. Knoke reported: "The fire spread out along
18078-400: Was the result of a proposal to assemble Fortresses in Consolidated plants, with the company returning with its own design of a longer-range, faster and higher-flying aircraft that could carry an extra ton of bombs. Early orders were for France (delivered to the RAF after the fall of France) and Britain, already at war, with just a batch of 36 for the USAAF. Neither the USAAF nor the RAF judged
18216-598: Was to have an estimated gross weight of 101,000 lb (46,000 kg). The first contract for two XB-32s was signed on 6 September 1940, the same day as the contract for the Boeing prototype XB-29. The first XB-32-CO, AAF s/n 41-141, was constructed next to the Army Air Forces (AAF) Base Tarrant Field Airdrome at the AAF Aircraft Plant No. 4 just west of Fort Worth, Texas along the south side of Lake Worth. The Consolidated Vultee Bomber Plant assembly line
18354-489: Was too great for fighter escorts based in Japan, so the B-29s flew alone. In November, Mikoyan-Gurevich MiG-15s flown by Soviet pilots started to intercept the US bombers over North Korea. The MiG-15 was specifically designed to destroy US heavy bombers; it could out-perform any fighter deployed by United Nations air forces until the capable F-86 Sabre was produced in greater numbers and brought to Korea. After 28 B-29s were lost,
18492-442: Was used by Consolidated and the USAAC to test armor installations as well as self-sealing fuel tanks . Initially, these aircraft were to be given USAAC serials 39–681 to 39-687. Due to deferments of the US requirements, the US purchase was twice postponed, and the serial numbers were changed to 40–696 to 40-702. When the RAF purchased the first six YB-24 aircraft, the serial numbers were reassigned to an early batch of B-24D funded by

18906-441: Was vital for missions of a radius less than 1,000 mi (1,600 km), in both the Atlantic and Pacific theaters where U.S. Navy PB4Y-1s and USAAF SB-24s took a heavy toll of enemy submarines and surface combatants and shipping. The United States Army Air Forces (USAAF) took delivery of its first B-24As in mid-1941. Over the next three years, B-24 squadrons deployed to all theaters of the war: African, European, China-Burma-India,
19044-421: Was written off due to battle damage and the other crash-landed on a beach. US-based Liberators entered combat service in 1942 when on 6 June, four LB-30s from Hawaii staging through Midway Island attempted an attack on Wake Island , but were unable to find it.
