94-625: The Short Shetland was intended as a British long-range, four-engined flying boat built by Short Brothers at Rochester, Kent for use in the Second World War . It was designed to meet an Air Ministry requirement (defined in Specification R.14/40 ) for a very-long range reconnaissance flying boat. The design used the company's experience with large scale production of the Short Sunderland . Two prototypes flew, but

188-562: A United States naval aviator in an M.5. The Aeromarine Plane and Motor Company modified the Felixstowe F.5 into Aeromarine 75 airliner flying boats which with Aeromarine West Indies Airways flew Air Mail to Florida, Bahamas, and Cuba along with being passenger carriers. The German aircraft manufacturing company Hansa-Brandenburg built flying boats starting with the model Hansa-Brandenburg GW in 1916. The Austro-Hungarian firm, Lohner-Werke began building flying boats, starting with

282-469: A five-seat Sanchez-Besa from 1 August 1912. The French Navy ordered its first floatplane in 1912. None of these crafts to date were flying boats. In 1911–12, François Denhaut constructed the first flying boat , with a fuselage forming a hull, using various designs to give hydrodynamic lift at take-off. Its first successful flight was on 13 April 1912. Throughout 1910 and 1911 American pioneering aviator Glenn Curtiss developed his floatplane into

376-698: A fully enclosed cabin. Trials of the America began on 23 June 1914 with Porte also as Chief Test Pilot; testing soon revealed serious shortcomings in the design; it was under-powered, so the engines were replaced with more powerful engines mounted in a tractor configuration. There was also a tendency for the nose of the aircraft to try to submerge as engine power increased while taxiing on water. This phenomenon had not been encountered before, since Curtiss' earlier designs had not used such powerful engines nor large fuel/cargo loads and so were relatively more buoyant. In order to counteract this effect, Curtiss fitted fins to

470-581: A further sum" from the Women's Aerial League of Great Britain. American businessman Rodman Wanamaker became determined that the prize should go to an American aircraft and commissioned the Curtiss Aeroplane and Motor Company to design and build an aircraft capable of making the flight. Curtiss' development of the Flying Fish flying boat in 1913 brought him into contact with John Cyril Porte ,

564-585: A glide." At Felixstowe, Porte made advances in flying boat design and developed a practical hull design with the distinctive "Felixstowe notch". Porte's first design to be implemented in Felixstowe was the Felixstowe Porte Baby , a large, three-engined biplane flying-boat, powered by one central pusher and two outboard tractor Rolls-Royce Eagle engines. Porte modified an H-4 with a new hull whose improved hydrodynamic qualities made taxiing, take-off and landing much more practical, and called it

658-493: A heavily modified Short Empire flying boat. The larger Maia took off, carrying the smaller Mercury loaded to a weight greater than it could take off with. This allowed the Mercury to carry sufficient fuel for a direct trans-Atlantic flight with the mail. Unfortunately this was of limited usefulness, and the Mercury had to be returned from America by ship. The Mercury did set a number of distance records before in-flight refuelling

752-459: A joint bid. A company under combined ownership was then formed, Qantas Empire Airways. The new ten-day service between Rose Bay, New South Wales (near Sydney ), and Southampton was such a success with letter-writers that before long the volume of mail was exceeding aircraft storage space. A better solution to the problem was sought by the British government during the early 1930s, who released

846-592: A larger and more streamlined form of airship designed by German Count Ferdinand von Zeppelin , were outfitted to carry bombs to attack targets at long range. These were the first long range, strategic bombers. Although the German air arm was strong, with a total of 123 airships by the end of the war, they were vulnerable to attack and engine failure, as well as navigational issues. German airships inflicted little damage on all 51 raids, with 557 Britons killed and 1,358 injured. The German Navy lost 53 of its 73 airships, and

940-483: A major limitation, combined with the desire for accuracy and other operational factors, bomber designs tended to be tailored to specific roles. By the start of the war this included: Bombers of this era were not intended to attack other aircraft although most were fitted with defensive weapons. World War II saw the beginning of the widespread use of high speed bombers which began to minimize defensive weaponry in order to attain higher speed. Some smaller designs were used as

1034-538: A means of evading detection and attack. Designs such as the English Electric Canberra could fly faster or higher than contemporary fighters. When surface-to-air missiles became capable of hitting high-flying bombers, bombers were flown at low altitudes to evade radar detection and interception. Once "stand off" nuclear weapon designs were developed, bombers did not need to pass over the target to make an attack; they could fire and turn away to escape

1128-458: A publicity stunt. It flew to America in 1930–31, crossing the Atlantic via an indirect route over 9 months. It was the largest flying boat of its time, but was severely underpowered and was limited by a very low operational ceiling. Only three were built, with a variety of different engines installed, in an attempt to overcome the lack of power. Two of these were sold to Italy. The Dornier Wal

1222-598: A result of this action, British flying boats were dazzle-painted to aid identification in combat. The Curtiss Aeroplane and Motor Company independently developed its designs into the small Model "F", the larger Model "K" (several of which were sold to the Russian Naval Air Service), and the Model "C" for the U.S. Navy. Curtiss among others also built the Felixstowe F.5 as the Curtiss F5L, based on

1316-449: A retired Royal Navy lieutenant, aircraft designer and test pilot who was to become an influential British aviation pioneer. Recognising that many of the early accidents were attributable to a poor understanding of handling while in contact with the water, the pair's efforts went into developing practical hull designs to make the transatlantic crossing possible. At the same time the British boat building firm J. Samuel White of Cowes on

1410-667: A single Sunderland operating off Norway was attacked by six German Junkers Ju 88C fighters; during the engagement, it shot one down and damaged another until it retreated and drove off the rest. The Germans reputedly nicknamed the Sunderland the Fliegendes Stachelschwein ("Flying Porcupine") due to its defensive firepower. Sunderlands in the Mediterranean theatre proved themselves on multiple high-profile occasions, flying many evacuation missions during

1504-493: A specification calling for a new large aircraft capable of carrying up to 24 passengers in spacious comfort along with adequate room for airmail or freight while simultaneously being capable of a cruising speed of 170 mph and a range of at least 700 miles; the capacity for an extended range of 2,000 miles to serve the North Atlantic route was also stipulated. Originally intended for use by IAL, partner Qantas agreed to

1598-562: A weak hull and poor water handling. The combination of the new Porte-designed hull, this time fitted with two steps, with the wings of the H-12 and a new tail, and powered by two Rolls-Royce Eagle engines, was named the Felixstowe F.2 and first flew in July 1916, proving greatly superior to the Curtiss on which it was based. It was used as the basis for all future designs. It entered production as

1692-433: Is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and

1786-492: Is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. During WWII with engine power as a major limitation, combined with the desire for accuracy and other operational factors, bomber designs tended to be tailored to specific roles. Early in the Cold War however, bombers were the only means of carrying nuclear weapons to enemy targets, and held

1880-488: Is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. This role is filled by tactical bomber class, which crosses and blurs with various other aircraft categories: light bombers , medium bombers , dive bombers , interdictors , fighter-bombers , attack aircraft , multirole combat aircraft , and others. The first use of an air-dropped bomb (actually four hand grenades specially manufactured by

1974-799: The Bristol Aeroplane Company . They were fitted with a prismatic Bombsight in the front cockpit and a cylindrical bomb carrier in the lower forward fuselage capable of carrying twelve 10 lb (4.5 kg) bombs, which could be dropped singly or as a salvo as required. The aircraft was purchased for use both by the Royal Naval Air Service and the Royal Flying Corps (RFC), and three T.B.8s, that were being displayed in Paris during December 1913 fitted with bombing equipment, were sent to France following

2068-538: The Felixstowe F.1 . Porte's innovation of the "Felixstowe notch" enabled the craft to overcome suction from the water more quickly and break free for flight much more easily. This made operating the craft far safer and more reliable, although similar devices had been in use in France since 1911. The "notch" breakthrough would soon after evolve into a "step", with the rear section of the lower hull sharply recessed above

2162-498: The First World War , flying boats rapidly grew in both scale and capability during the interwar period , during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during the Second World War . Their advantage lay in using water instead of expensive land-based runways, making them

2256-683: The German seizure of Crete , each carrying as many as 82 passengers. One Sunderland flew the reconnaissance mission to observe the Italian fleet at anchor in Taranto before the famous Royal Navy Fleet Air Arm 's torpedo attack on 11 November 1940 . The largest flying boat of the war was the Blohm & Voss BV 238 , which was also the heaviest plane to fly during the Second World War and

2350-603: The Gnome Omega –powered Hydravion , a trimaran floatplane. Fabre's first successful take off and landing by a powered floatplane inspired other aviators and he designed floats for several other flyers. The first hydro-aeroplane competition was held in Monaco in March 1912, featuring aircraft using floats from Fabre, Curtiss, Tellier and Farman. This led to the first scheduled seaplane passenger services at Aix-les-Bains , using

2444-551: The Handley Page Type O ; the majority of bombing was done by single-engined biplanes with one or two crew members flying short distances to attack enemy lines and immediate hinterland. As the effectiveness of a bomber was dependent on the weight and accuracy of its bomb load, ever larger bombers were developed starting in World War I, while considerable money was spent developing suitable bombsights. With engine power as

2538-763: The Isle of Wight set up a new aircraft division and produced a flying boat in the United Kingdom. This was displayed at the London Air Show at Olympia in 1913. In that same year, a collaboration between the S. E. Saunders boatyard of East Cowes and the Sopwith Aviation Company produced the "Bat Boat", an aircraft with a consuta laminated hull that could operate from land or on water, which today we call an amphibious aircraft . The "Bat Boat" completed several landings on sea and on land and

2632-585: The Italo-Turkish War , with the first major deployments coming in the First World War and Second World War by all major airforces, damaging cities, towns, and rural areas. The first bomber planes in history were the Italian Caproni Ca 30 and British Bristol T.B.8 , both of 1913. Some bombers were decorated with nose art or victory markings . There are two major classifications of bomber: strategic and tactical. Strategic bombing

2726-648: The Lohner E in 1914 and the later (1915) Lohner L which was copied widely. In September 1919, British company Supermarine started operating the first flying boat service in the world, from Woolston to Le Havre in France , but it was short-lived. A Curtiss NC-4 became the first aircraft to fly across the Atlantic Ocean in 1919, crossing via the Azores . Of the four that made the attempt, only one completed

2820-692: The Shin Meiwa US-1A and the Martin JRM Mars . In the 21st century, flying boats maintain a few niche uses, such as dropping water on forest fires , air transport around archipelagos, and access to undeveloped areas. Many modern seaplane variants, whether float or flying boat types, are convertible amphibious aircraft where either landing gear or flotation modes may be used to land and take off. The quest for an aircraft that could take off or land from water began with float planes, which are not flying boats. The Frenchman Alphonse Pénaud filed

2914-641: The Turkish railway station of Karağaç (near the besieged Edirne ) from an Albatros F.2 aircraft piloted by Radul Milkov , during the First Balkan War . This is deemed to be the first use of an aircraft as a bomber. The first heavier-than-air aircraft purposely designed for bombing were the Italian Caproni Ca 30 and British Bristol T.B.8 , both of 1913. The Bristol T.B.8 was an early British single engined biplane built by

3008-966: The V bomber force was phased out; the last of which left service in 1983. The French Mirage IV bomber version was retired in 1996, although the Mirage 2000N and the Rafale have taken on this role. The only other nation that fields strategic bombing forces is China , which has a number of Xian H-6s . Currently, only the United States Air Force , the Russian Aerospace Forces ' Long-Range Aviation command, and China's People's Liberation Army Air Force operate strategic heavy bombers. Other air forces have transitioned away from dedicated bombers in favor of multirole combat aircraft . At present, these air forces are each developing stealth replacements for their legacy bomber fleets,

3102-521: The 1930s, flying boats made it possible to have regular air transport between the U.S. and Europe, opening up new air travel routes to South America, Africa, and Asia. Foynes , Ireland and Botwood , Newfoundland and Labrador were the termini for many early transatlantic flights. In areas where there were no airfields for land-based aircraft, flying boats could stop at small island, river, lake or coastal stations to refuel and resupply. The Pan Am Boeing 314 Clipper planes brought exotic destinations like

3196-509: The 1950s-designed B-52s are projected to remain in use until the 2040s. Similarly, the Soviet Union used the intermediate-range Tu-22M 'Backfire' in the 1970s, but their Mach 3 bomber project stalled. The Mach 2 Tu-160 'Blackjack' was built only in tiny numbers, leaving the 1950s Tupolev Tu-16 and Tu-95 'Bear' heavy bombers to continue being used into the 21st century. The British strategic bombing force largely came to an end when

3290-629: The Allied Armies." When the war started, bombing was very crude (hand-held bombs were thrown over the side) yet by the end of the war long-range bombers equipped with complex mechanical bombing computers were being built, designed to carry large loads to destroy enemy industrial targets. The most important bombers used in World War I were the French Breguet 14 , British de Havilland DH-4 , German Albatros C.III and Russian Sikorsky Ilya Muromets . The Russian Sikorsky Ilya Muromets ,

3384-600: The Curtiss Model E, and soon tested landings on and take-offs from ships using the Curtiss Model D. In Britain, Captain Edward Wakefield and Oscar Gnosspelius began to explore the feasibility of flight from water in 1908. They decided to make use of Windermere in the Lake District , England's largest lake to test their floatplane. The latter's first attempts to fly attracted large crowds, though

3478-518: The Far East within reach of air travelers and came to represent the romance of flight. By 1931, mail from Australia was reaching Britain in just 16 days – less than half the time taken by sea. In that year, government tenders on both sides of the world invited applications to run new passenger and mail services between the ends of the British Empire , and Qantas and IAL were successful with

3572-473: The Felixstowe F.2A, being used as a patrol aircraft, with about 100 being completed by the end of World War I. Another seventy were built, and these were followed by two F.2c, which were built at Felixstowe. The Felixstowe F.5 was intended to combine the good qualities of the F.2 and F.3, with the prototype first flying in May 1918. The prototype showed superior qualities to its predecessors but, to ease production,

3666-604: The German Army lost 26 of its 50 ships. The Caproni Ca 30 was built by Gianni Caproni in Italy . It was a twin-boom biplane with three 67 kW (80 hp) Gnome rotary engines and first flew in October 1914 . Test flights revealed power to be insufficient and the engine layout unworkable, and Caproni soon adopted a more conventional approach installing three 81 kW (110 hp) Fiat A.10s . The improved design

3760-598: The Italian naval arsenal) was carried out by Italian Second Lieutenant Giulio Gavotti on 1 November 1911 during the Italo-Turkish war in Libya – although his plane was not designed for the task of bombing, and his improvised attacks on Ottoman positions had little impact. These picric acid -filled steel spheres were nicknamed "ballerinas" from the fluttering fabric ribbons attached. On 16 October 1912, Bulgarian observer Prodan Tarakchiev dropped two of those bombs on

3854-620: The L series, and progressing with the M series. The Macchi M.5 in particular was extremely manoeuvrable and agile and matched the land-based aircraft it had to fight. 244 were built in total. Towards the end of the First World War, the aircraft were flown by the Italian Navy Aviation, the United States Navy and United States Marine Corps airmen. Ensign Charles Hammann won the first Medal of Honor awarded to

3948-616: The Navy, as a member of the Royal Naval Air Service . Appointed Squadron Commander of Royal Navy Air Station Hendon , he soon convinced the Admiralty of the potential of flying boats and was put in charge of the naval air station at Felixstowe in 1915. Porte persuaded the Admiralty to commandeer (and later, purchase) the America and a sister craft from Curtiss. This was followed by an order for 12 more similar aircraft, one Model H-2 and

4042-569: The River Seine with a towed kite glider on floats. The first of his unpowered flights was 150 yards. He later built a powered floatplane in partnership with Louis Blériot , but the machine was unsuccessful. Other pioneers also attempted to attach floats to aircraft in Britain, Australia, France and the USA. On 28 March 1910, Frenchman Henri Fabre flew the first successful powered floatplane,

The B-21 would be capable of loitering near target areas for extended periods of time. Occasionally, military aircraft have been used to bomb ice jams with limited success as part of an effort to clear them. In 2018,

Notably, bombing campaigns formed a part of the British offensive at the Battle of Neuve Chapelle in 1915, with Royal Flying Corps squadrons attacking German railway stations in an attempt to hinder the logistical supply of the German army . The early, improvised attempts at bombing that characterized

4324-459: The aircraft burnt out at its moorings on 28 January 1946 as a result of a galley fire. With the end of the war, the second prototype (serial number DX171 ) was completed as a civil transport and designated Shetland II . It was designed to carry 70 passengers but only 40 seats were fitted. Registered G-AGVD, the Shetland Mk.II's first flight took place on 17 September 1947. After trials, it

4418-465: The aircraft crashed into the lake. Wakefield's pilot however, taking advantage of a light northerly wind, successfully took off and flew at a height of 50 feet to Ferry Nab, where he made a wide turn and returned for a perfect landing on the lake's surface. In 1913, the Daily Mail newspaper put up a £10,000 prize for the first non-stop aerial crossing of the Atlantic which was soon "enhanced by

4512-400: The aircraft failed to take off and required a re-design of the floats incorporating features of Borwick's successful speed-boat hulls. Meanwhile, Wakefield ordered a floatplane similar to the design of the 1910 Fabre Hydravion. By November 1911, both Gnosspelius and Wakefield had aircraft capable of flight from water and awaited suitable weather conditions. Gnosspelius's flight was short-lived as

4606-633: The basis for night fighters . A number of fighters, such as the Hawker Hurricane were used as ground attack aircraft, replacing earlier conventional light bombers that proved unable to defend themselves while carrying a useful bomb load. At the start of the Cold War, bombers were the only means of carrying nuclear weapons to enemy targets, and had the role of deterrence . With the advent of guided air-to-air missiles, bombers needed to avoid interception. High-speed and high-altitude flying became

4700-617: The basis for international airlines in the interwar period. They were also commonly used as maritime patrol aircraft and air-sea rescue , particularly during times of conflict. Flying boats such as the PBY Catalina and Short Sunderland played key roles in both the Pacific Theater and the Atlantic of the Second World War. The popularity of flying boats gradually tailed off during the Cold War era, partially because of

4794-431: The best flying boat of the conflict, the Kawanishi H8K . Its design was based upon its immediate predecessor, the Kawanishi H6K , but was a considerably larger and longer-ranged aircraft designed at the request of the Navy just prior to the outbreak of war. On the night of 4 March 1942, two H8Ks conducted the second raid on Pearl Harbor , refuelling en route by submarine at French Frigate Shoals in order to achieve

4888-436: The blast. Nuclear strike aircraft were generally finished in bare metal or anti-flash white to minimize absorption of thermal radiation from the flash of a nuclear explosion . The need to drop conventional bombs remained in conflicts with non-nuclear powers, such as the Vietnam War or Malayan Emergency . The development of large strategic bombers stagnated in the later part of the Cold War because of spiraling costs and

4982-434: The change being made official on 1 April 1940. BOAC continued to operate flying boat services from the (slightly) safer confines of Poole Harbour during wartime, returning to Southampton in 1947. When Italy entered the war in June 1940, the Mediterranean was closed to allied planes, and BOAC and Qantas operated the Horseshoe Route between Durban and Sydney using Short Empire flying boats. The Martin Company produced

5076-418: The competitive tender for R.14/40; Saro proposed the Saunders-Roe S.41 . Rather than selecting either company's design, the Air Ministry asked the companies to submit a combined project, stipulating the terms under which the work was to be shared between them. The detailed design was performed by Saro, its experience with the Saro Shrimp contributing to the hull shape, as well as building the wing. Shorts built

5170-426: The development of the Intercontinental ballistic missile (ICBM) – which was felt to have similar deterrent value while being impossible to intercept. Because of this, the United States Air Force XB-70 Valkyrie program was cancelled in the early 1960s; the later B-1B Lancer and B-2 Spirit aircraft entered service only after protracted political and development problems. Their high cost meant that few were built and

5264-407: The difficulty in maintaining operations in inclement weather when sea conditions may easily prevent takeoffs and landings while land based aircraft are unaffected, and investments in airports during the conflict that eased the introduction of larger, and more efficient, land-based airliners. Despite being largely overshadowed, limited use of the type continued with some operators, such as in the case of

5358-420: The early part of the war slowly gave way to a more organized and systematic approach to strategic and tactical bombing, pioneered by various air power strategists of the Entente , especially Major Hugh Trenchard ; he was the first to advocate that there should be "... sustained [strategic bombing] attacks with a view to interrupting the enemy's railway communications ... in conjunction with the main operations of

5452-419: The end of World War II prevented the Shetland from entering production. It was the first aircraft designed with a 110 volt electrical system. Specification R.14/40 replaced an earlier specification R.5/39 which was an up-armed revision of specification R.3/38 for a faster flying boat than the Short Sunderland . Shorts , among others, had tendered a design for R.5/39 but the ministry had changed its mind about

5546-489: The end of the conflict, the Navy opted to scaled back their order, buying only the five aircraft. The five Mars were completed, and the last delivered in 1947. The U.S. used several 4-engine flying boats during World War II, including those that had been operating as civilian airliners. This included five Boeing B-314 Clippers , four more as the C-98s; two Martin M-130 Clippers ,a Martin XPB2M-1/XPB2M-1R prototype, and one JRM-1 Mars ; three Sikorsky VS-44s (JR2S-1). However,

5640-647: The enemy's ability to wage war by limiting access to resources through crippling infrastructure or reducing industrial output. Current examples include the strategic nuclear-armed bombers: B-2 Spirit , B-52 Stratofortress , Tupolev Tu-95 'Bear' , Tupolev Tu-22M 'Backfire' and Tupolev Tu-160 "Blackjack" ; historically notable examples are the: Gotha G.IV , Avro Lancaster , Heinkel He 111 , Junkers Ju 88 , Boeing B-17 Flying Fortress , Consolidated B-24 Liberator , Boeing B-29 Superfortress , and Tupolev Tu-16 'Badger'. Tactical bombing , aimed at countering enemy military activity and in supporting offensive operations,

5734-486: The final Porte hull designs and powered by American Liberty engines . Meanwhile, the pioneering flying boat designs of François Denhaut had been steadily developed by the Franco-British Aviation Company into a range of practical craft. Smaller than the Felixstowes, several thousand FBAs served with almost all of the Allied forces as reconnaissance craft, patrolling the North Sea, Atlantic and Mediterranean oceans. In Italy, several flying boats were developed, starting with

5828-449: The first patent for a flying machine with a boat hull and retractable landing gear in 1876 but failed to build one. Austrian Wilhelm Kress is credited by some with attempting to build the first successful seaplane Drachenflieger , a floatplane , in 1898, although its two 30 hp Daimler engines were inadequate for take-off and it later sank when one of its two floats collapsed. On 6 June 1905, Gabriel Voisin took off and landed on

5922-528: The flight plan; the aircraft was a conventional biplane design with two-bay, unstaggered wings of unequal span with two pusher inline engines mounted side-by-side above the fuselage in the interplane gap. Wingtip pontoons were attached directly below the lower wings near their tips. The design (later developed into the Model H ), resembled Curtiss' earlier flying boats, but was built considerably larger so it could carry enough fuel to cover 1,100 mi (1,800 km). The three crew members were accommodated in

6016-449: The flight. Before the development of highly reliable aircraft, the ability to land on water was a desirable safety feature for transoceanic travel. In 1923, the first successful commercial flying boat service was introduced with flights to and from the Channel Islands . The British aviation industry was experiencing rapid growth. The Government decided that nationalization was necessary and ordered five aviation companies to merge to form

6110-417: The forward lower hull section, and that characteristic became a feature of both flying boat hulls and floatplane floats. The resulting aircraft would be large enough to carry sufficient fuel to fly long distances and could berth alongside ships to take on more fuel. Porte then designed a similar hull for the larger Curtiss H-12 flying boat which, while larger and more capable than the H-4s, shared failings of

6204-401: The hull, tail and the final assembly. The first prototype and what was to be the only Shetland I ( military serial number DX166 ) first flew on 14 December 1944, piloted by Shorts' chief test pilot John Lankester Parker as captain and Geoffrey Tyson as co-pilot. The aircraft flew without gun turrets (its role having been revised to that of unarmed transport before its maiden flight. It

Being ordered from aviation manufacturer Short Brothers , the Empire was reportedly hailed as being "one of the world's boldest experiments in aviation", while early sceptics referred to the order less favourably as being a 'gamble'. IAL were so impressed by the Empire that it placed a follow-on order for another 11; when combined with

Months later, it was strafed and partially sunk while moored on Lake Schaal , to the east of Hamburg ; it never returned to flight, instead being intentionally sunk in deep water after the end of the conflict. The Imperial Japanese Navy operated what has been often described as

Bomber A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs , launch torpedoes , or deploy air-launched cruise missiles . Bombs were first dropped from an aircraft during

6580-444: The most notable of these flights was a 43,500 km (27,000 mi) expedition conducted during 1927 and 1928; it was carried out by four Southamptons of the Far East Flight , setting out from Felixstowe via the Mediterranean and India to Singapore . Both the RAF and Supermarine acquired considerable acclaim from these flights, as well as proving that flying boats had evolved to become reliable means of long-distance transport. In

6674-448: The necessary range; poor visibility caused this attack on Pearl Harbor to fail to accomplish any significant damage. An improved H8K2 variant of the type, featuring extremely heavy defensive armament, was also introduced. In November 1939, IAL was restructured into three separate companies: British European Airways , British Overseas Airways Corporation (BOAC), and British South American Airways (which merged with BOAC in 1949), with

6768-589: The need for an immediate replacement for the Sunderland. R.5/39 had considered a maximum weight up to 84,000 lb (38,102 kg) – R.14/40 allowed for a maximum takeoff of nearly 100,000 lb (45,359 kg) with a bomb load of 20,000 lb (9,072 kg). The projected engines were the Bristol Centaurus radial or the Napier Sabre inline. Shorts and the other British manufacturer of big flying boats, Saunders-Roe (Saro), were involved in

6862-491: The original order for 28 flying boats, this was the largest single order to have ever been placed for a British civil aircraft at that time. Delivering the mail as quickly as possible generated a lot of competition and some innovative designs. One variant of the Short Empire flying boats was the strange-looking " Maia and Mercury ". It was a four-engined floatplane "Mercury" (the winged messenger) fixed on top of "Maia",

6956-421: The outbreak of war. Under the command of Charles Rumney Samson , a bombing attack on German gun batteries at Middelkerke , Belgium was executed on 25 November 1914. The dirigible, or airship, was developed in the early 20th century. Early airships were prone to disaster, but slowly the airship became more dependable, with a more rigid structure and stronger skin. Prior to the outbreak of war, Zeppelins ,

7050-583: The over-water sectors of the Deutsche Luft Hansa South Atlantic Airmail service. The military value of flying boats was well recognized, and every country bordering on water operated them in a military capacity at the outbreak of the Second World War . Flying boats such as the PBM Mariner patrol bomber, PBY Catalina , Short Sunderland , and Grumman Goose were procured in large numbers. The Sunderland, which

7144-575: The production version was modified to make extensive use of components from the F.3, which resulted in lower performance than the F.2A or F.3. The Felixstowe flying boats were extensively employed by the Royal Navy for coastal patrols, including searching for German U-boats . In 1918 they were towed on lighters towards the northern German ports to extend their range; on 4 June 1918 this resulted in three F.2As engaging with ten German seaplanes, shooting down two confirmed and four probables at no loss. As

7238-541: The prototype XPB2M Mars based on their PBM Mariner patrol bomber, with flight tests between 1941 and 1943. The Mars was converted by the Navy into a transport aircraft designated the XPB2M-1R. Satisfied with the performance, 20 of the modified JRM-1 Mars were ordered. The first of the five production Mars flying boats entered service ferrying cargo to Hawaii and the Pacific Islands on 23 January 1944. Following

7332-501: The remaining as Model H-4 's. Four examples of the latter were assembled in the UK by Saunders . All of these were similar to the design of the America and, indeed, were all referred to as America s in Royal Navy service. The engines, however, were changed from the under-powered 160 hp Curtiss engines to 250 hp Rolls-Royce Falcon engines. The initial batch was followed by an order for 50 more (totalling 64 Americas overall during

7426-585: The role of deterrence . With the advent of guided air-to-air missiles, bombers needed to avoid interception. High-speed and high-altitude flying became a means of evading detection and attack. With the advent of ICBMs the role of the bomber was brought to a more tactical focus in close air support roles, and a focus on stealth technology for strategic bombers. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets such as supply bases, bridges, factories, shipyards, and cities themselves, to diminish

7520-406: The sides of the bow to add hydrodynamic lift, but soon replaced these with sponsons , a type of underwater pontoon mounted in pairs on either side of a hull. These sponsons (or their engineering equivalents) and the flared, notched hull would remain a prominent feature of flying boat hull design in the decades to follow. With the problem resolved, preparations for the crossing resumed. While the craft

7614-568: The state-owned Imperial Airways of London (IAL). IAL became the international flag-carrying British airline, providing flying boat passenger and mail transport links between Britain and South Africa using aircraft such as the Short S.8 Calcutta . During the 1920s, the Royal Air Force (RAF) Far East flight performed a series of "showing the flag" long-distance formation flights using the newly developed Supermarine Southampton . Perhaps

7708-540: The successful Curtiss Model D land-plane, which used a larger central float and sponsons. Combining floats with wheels, he made the first amphibian flights in February 1911 and was awarded the first Collier Trophy for US flight achievement. From 1912 his experiments resulted in the 1913 Model E and Model F , which he called "flying-boats". In February 1911, the United States Navy took delivery of

7802-480: The vast distances of the Pacific Theater and the Atlantic , locating enemy vessels and sinking numerous submarines. In May 1941, the German battleship Bismarck was discovered by a PBY Catalina flying out of Castle Archdale Flying boat base , Lower Lough Erne , Northern Ireland. A flight of Catalinas spotted the Japanese fleet approaching Midway Island , beginning the Battle of Midway . On 3 April 1940,

7896-566: The war). Porte also acquired permission to modify and experiment with the Curtiss aircraft. The Curtiss H-4s were soon found to have a number of problems; they were underpowered, their hulls were too weak for sustained operations and they had poor handling characteristics when afloat or taking off. One flying boat pilot, Major Theodore Douglas Hallam, wrote that they were "comic machines, weighing well under two tons; with two comic engines giving, when they functioned, 180 horsepower; and comic control, being nose heavy with engines on and tail heavy in

7990-522: Was "easily the greatest commercial success in the history of marine aviation". Over 250 were built in Italy, Spain, Japan, The Netherlands and Germany. Numerous airlines operated the Dornier Wal on scheduled passenger and mail services. Wals were used by explorers, for a number of pioneering flights, and by the military in many countries. Though having first flown in 1922, from 1934 to 1938 Wals operated

8084-442: Was adopted. Sir Alan Cobham devised a method of in-flight refuelling in the 1930s. In the air, the Short Empire could be loaded with more fuel than it could take off with. Short Empire flying boats serving the trans-Atlantic crossing were refueled over Foynes; with the extra fuel load, they could make a direct trans-Atlantic flight. A Handley Page H.P.54 Harrow was used as the fuel tanker. The German Dornier Do X flying boat

8178-467: Was bought by the Italian Army and it was delivered in quantity from August 1915 . While mainly used as a trainer , Avro 504s were also briefly used as bombers at the start of the First World War by the Royal Naval Air Service (RNAS) when they were used for raids on the German airship sheds. Bombing raids and interdiction operations were mainly carried out by French and British forces during

8272-539: Was delivered to Short's factory at Belfast, but no orders were forthcoming and it performed only limited flight trials before being scrapped in 1951. Data from British Flying Boats General characteristics Performance Armament Aircraft of comparable role, configuration, and era Flying boat Though a flying boat’s fuselage provides buoyancy, it may also utilize under-wing floats or wing-like hull projections (called sponsons ) for additional stability. Ascending into common use during

8366-508: Was delivered to the Marine Aircraft Experimental Establishment (MAEE) at Felixstowe in October 1945. Testing indicated satisfactory water handling but the stabilising floats were mounted too low and did not offer sufficient clearance for takeoffs with maximum load. Flight testing revealed problems with the harmonisation of controls and marginal longitudinal stability. Before the trials were complete,

8460-527: Was developed in parallel to the civilian Empire flying boat, was one of the most powerful and widely used flying boats throughout the conflict, while Catalinas were one of the most produced ASW of the war, with over 2,661 being produced in the US alone. Flying boats were commonly utilized to conduct various tasks, from anti-submarine patrol to air-sea rescue and gunfire spotting for battleships. They would recover downed airmen and operate as scout aircraft over

8554-478: Was duly awarded the Mortimer Singer Prize . It was the first all-British aeroplane capable of making six return flights over five miles within five hours. In the U.S. Wanamaker's commission built on Glen Curtiss' previous development and experience with the Model F for the U.S. Navy which rapidly resulted in the America , designed under Porte's supervision following his study and rearrangement of

8648-400: Was found to handle "heavily" on takeoff, and required rather longer take-off distances than expected, the full moon on 5 August 1914 was selected for the trans-Atlantic flight; Porte was to pilot the America with George Hallett as co-pilot and mechanic. Curtiss and Porte's plans were interrupted by the outbreak of the First World War. Porte sailed for England on 4 August 1914 and rejoined

8742-508: Was noticeably different from its UK and U.S.-built counterparts. It had wing-like protrusions from the fuselage, called sponsons , to stabilize it on the water without the need for wing-mounted outboard floats. This feature was pioneered by Claudius Dornier during the First World War on his Dornier Rs. I giant flying boat, and perfected on the Dornier Wal in 1924. The enormous Do X was powered by 12 engines and once carried 170 persons as

8836-525: Was the first four-engine bomber to equip a dedicated strategic bombing unit during World War I . This heavy bomber was unrivaled in the early stages of the war, as the Central Powers had no comparable aircraft until much later. Long range bombing raids were carried out at night by multi-engine biplanes such as the Gotha G.IV (whose name was synonymous with all multi-engine German bombers) and later
