It had a good rate-of-roll, better than the Spitfire, so I would say the plusses to the Spitfire and the Mustang just about equate. If I were in a dogfight, I'd prefer to be flying the Spitfire. The problem was I wouldn't like to be in a dogfight near Berlin, because I could never get home to Britain in a Spitfire! The U.S. Air Forces, Flight Test Engineering, assessed
2768-484: A more modern fighter. The prototype NA-73X airframe was completed on 9 September 1940, 102 days after contract signing, achieving its first flight on 26 October. The Mustang was designed to use the Allison V-1710 engine without an export-sensitive turbosupercharger or a multi-stage supercharger, resulting in limited high-altitude performance. The aircraft was first flown operationally and very successfully by

11937-405: The British Aircraft Purchasing Commission signed its first contract for the North American NA-73 on 24 April 1940, before Lend-Lease was in effect. Thus, the initial order for the P-51 Mustang (as it was later known) was placed by the British under the " cash and carry " program, as required by the US Neutrality Acts of the 1930s. After the arrival of the initial aircraft in the UK in October 1941,
12110-403: The British officials. Self was concerned that NAA had not ever designed a fighter, insisting they obtain the drawings and study the wind-tunnel test results for the P-40, before presenting them with detailed design drawings based on the agreed concept. NAA purchased the drawings and data from Curtiss for £56,000, confirming the purchase with the British Purchasing Commission. The commission approved
12283-484: The Crown made it part of the territory reserved for Indians west of the Appalachians, and then part of the British Province of Quebec . In 1778, George Rogers Clark claimed Illinois County for Virginia . In a compromise, Virginia (and other states that made various claims) ceded the area to the new United States in the 1780s and it became part of the Northwest Territory , administered by the federal government and later organized as states. The Illinois-Wabash Company
12456-617: The Desert Shield Tanker Task Force. In addition to refueling such aircraft as the F-16 and A-10, the units transported military passengers and cargo. The 182nd Tactical Air Support Group was responsible for security at Peoria Airport , MacDill Air Force Base , Florida and Luke Air Force Base , Arizona . The 169th Tactical Air Support Squadron deployed 20 soldiers to Fort Hood , Texas and Fort Irwin , California to support National Guard training. On 16 July 1993,
12629-550: The European theater, the most claimed by any Allied fighter in air-to-air combat) and 4,131 destroyed on the ground. Losses were about 2,520 aircraft. The 8th Air Force's 4th Fighter Group was the top-scoring fighter group in Europe, with 1,016 enemy aircraft claimed destroyed. This included 550 claimed in aerial combat and 466 on the ground. In air combat, the top-scoring P-51 units (both of which exclusively flew Mustangs) were
12802-788: The Fox ( Meskwaki ), Iowa , Kickapoo , Mascouten , Piankeshaw , Shawnee , Wea , and Winnebago ( Ho-Chunk ) came into the area from the east and north around the Great Lakes. French explorers Jacques Marquette and Louis Jolliet explored the Illinois River in 1673. Marquette soon after founded a mission at the Grand Village of the Illinois in Illinois Country . In 1680, French explorers under René-Robert Cavelier, Sieur de La Salle and Henri de Tonti constructed
12975-518: The German airbases fell to the point where they were no longer considered worthwhile targets. On 21 May, targets were expanded to include railways, locomotives, and other rolling stock used by the Germans to transport materiel and troops, in missions dubbed "Chattanooga". The P-51 excelled at this mission, although losses were much higher on strafing missions than in air-to-air combat, partially because
13148-854: The Governor of Illinois ordered 270 members of the 126th Air Refueling Wing to State Active Duty to support the Illinois National Guard's flood control mission during the Great Flood of 1993 . Members patrolled levees, sandbagged boils and provided security on a 24 hours basis. Many guardsmen aided in evacuation of residents. Medical personnel aided thousands. The unit had members in Alton, Anna, Carrollton, Carbondale, Cahokia, East St. Louis, East Carondelet, Edwardsville, Evansville, Grafton, Granite City, Hartford, Jerseyville, Murphysboro, Prairie du Rocher, Quincy, Springfield, and Winchester. By
13321-462: The Great Lakes, and the invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden . In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network facilitated trade, commerce, and settlement, making the state
13494-582: The Ia (NA-91), produced for the British, were not equivalent to the P-51A which was a later model (NA-99). Two British Mustang Is were held back by the USAAF and given the provisional model number XP-51. The USAAF held back 57 Mustang Ia aircraft armed with 4 x 20mm Hispano cannon, from the third British order, converting most of them to tactical reconnaissance aircraft and designating them P-51-2/F6A. North American retained
13667-742: The Illinois Air National Guard is traced to an armory on Michigan Avenue and 16th Street in Chicago, in 1927. This was the first home of the 108th Observation Squadron , the oldest unit in the Illinois Air National Guard. The original 16 officers and 74 enlisted men were mostly World War I veterans from Chicago, flying PT-1 aircraft. From this small contingent grew a major operation that moved to Midway Municipal Airport . The unit distinguished itself in World War II , performing anti-submarine patrols in North American O-47 aircraft from
13840-502: The Luftwaffe than to the Allies and was never a serious threat. The Me 262A was a serious threat, but attacks on their airfields neutralized them. The pioneering Junkers Jumo 004 axial-flow jet engines of the Me 262As needed careful nursing by their pilots, and these aircraft were particularly vulnerable during takeoff and landing. Lt. Chuck Yeager of the 357th Fighter Group was one of
14013-513: The Luftwaffe wherever it could be found. The aim was to achieve air supremacy . Mustang groups were sent far ahead of the bombers in a "fighter sweep" to intercept German fighters. Bomber crews complained, but by June, supremacy was achieved. The Luftwaffe answered with the Gefechtsverband ("battle formation"). This consisted of a Sturmgruppe of heavily armed and armored Fw 190As escorted by two Begleitgruppen of Bf 109s, whose task
14186-442: The Merlin, enabling long flights over water at 50 ft (15 m) altitude before approaching the enemy coastline. Over land, these flights followed a zig-zag course, turning every six minutes to foil enemy attempts at plotting an interception. During the first 18 months of Rhubarb raids, RAF Mustang Mk.Is and Mk.Ias destroyed or heavily damaged 200 locomotives, over 200 canal barges, and an unknown number of enemy aircraft parked on
14359-588: The Mustang helped ensure Allied air superiority in 1944. The P-51 was also used by Allied air forces in the North African, Mediterranean , Italian , and Pacific theaters. During World War II, Mustang pilots claimed to have destroyed 4,950 enemy aircraft. At the start of the Korean War, the Mustang, by then redesignated F-51 , was the main fighter of the United States until jet fighters , including North American's F-86 Sabre , took over this role;
14532-509: The Mustang then became a specialized fighter-bomber. Despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After the Korean War, Mustangs became popular civilian warbirds and air racing aircraft. In 1938, the British government established a purchasing commission in the United States, headed by Sir Henry Self . Self was given overall responsibility for RAF production, research, and development, and also served with Sir Wilfrid Freeman ,
14705-560: The Mustang's liquid-cooled engine (particularly its liquid coolant system) was vulnerable to small-arms fire, unlike the air-cooled R-2800 radials of its Republic P-47 Thunderbolt stablemates based in England, regularly tasked with ground-strafing missions. Given the overwhelming Allied air superiority , the Luftwaffe put its effort into the development of aircraft of such high performance that they could operate with impunity, but which also made bomber attack much more difficult, merely from
14878-744: The National Guard mobilizations for the Korean War. After 3 months of training, the unit moved to Langley Air Force Base , Virginia . On 30 October 1951 the wing flew their B-26 Invader bombers across the Atlantic Ocean to Bordeaux-Mérignac Air Base , France. In December, the Wing's remaining personnel and equipment arrived aboard the USS General H. F. Hodges . The Wing participated in NATO exercises in several countries to include France,
15051-681: The RAF and as a tactical-reconnaissance aircraft and fighter-bomber (Mustang Mk I). In mid 1942, a development project known as the Rolls-Royce Mustang X , replaced the Allison engine with a Rolls-Royce Merlin 65 two-stage inter-cooled supercharged engine. During testing at Rolls-Royce's airfield at Hucknall in England , it was clear the engine dramatically improved the aircraft's performance at altitudes above 15,000 ft (4,600 m) without sacrificing range. Following receipt of
15224-699: The USAAF had become so interested in the Merlin Mustang project that an initial contract for 400 aircraft was placed three months beforehand in August. The conversion led to production of the P-51B beginning at NAA's Inglewood, California, plant in June 1943, and P-51s started to become available to the 8th and 9th air forces in the winter of 1943–1944. Conversion to the two-stage supercharged and intercooled Merlin 60 series, over 350 lb (160 kg) heavier than
15397-602: The United Kingdom, West Germany and Italy. On 12 May 1952 the 126th moved 90 km north of Paris to Laon-Couvron Air Base . On 1 January 1953, the 126th Bombardment Wing was released from federal service and returned home. In 1961, the 126th Air Refueling Group received the first aerial refueling mission in the Air National Guard , flying the KC-97 Stratocruiser . The KC-97 would take
15570-532: The V-1710-39. The RAF later operated 308 P-51Bs and 636 P-51Cs, which were known in RAF service as Mustang Mk IIIs; the first units converted to the type in late 1943 and early 1944. Mustang Mk III units were operational until the end of World War II, though many units had already converted to the Mustang Mk IV (P-51D) and Mk IVa (P-51K) (828 in total, comprising 282 Mk IV and 600 Mk IVa). As all except
15743-843: The XP-51B. Based on the Packard V-1650-3 duplicating the Merlin 61's performance, NAA estimated for the XP-78 a top speed of 445 mph (387 kn; 716 km/h) at 28,000 feet (8,500 m), and a service ceiling of 42,000 feet (13,000 m). Initial flights of what was known to Rolls-Royce as the Mustang X were completed at Hucknall in October 1942. The first flight of the US version, designated XP-51B took place in November 1942, but
15916-601: The amphibious Dieppe Raid on the French coast (19 August 1942), four British and Canadian Mustang squadrons, including 26 Squadron, saw action covering the assault on the ground. By 1943–1944, British Mustangs were used extensively to seek out V-1 flying bomb sites. The last RAF Mustang Mk I and Mustang Mk II aircraft were struck off charge in 1945. Army Co-operation Command used the Mustang's superior speed and long range to conduct low-altitude " Rhubarb " raids over continental Europe, sometimes penetrating German airspace. The V-1710 engine ran smoothly at 1,100 rpm, versus 1,600 for
16089-558: The area. In addition to these three, largely latitudinally defined divisions, all of the region outside the Chicago metropolitan area is often called " downstate " Illinois. This term is flexible, but is generally meant to mean everything outside the influence of the Chicago area. Thus, some cities in Northern Illinois, such as DeKalb , which is west of Chicago, and Rockford —which is actually north of Chicago—are sometimes incorrectly considered to be 'downstate'. Illinois has
16262-414: The attacks in May destroyed 94 square miles (240 km ) of buildings, which was equivalent to one-seventh of Japan's total urban area. The minister of home affairs , Iwao Yamazaki , concluded after these raids that Japan's civil defense arrangements were "considered to be futile". On the first day of June, 521 B-29s escorted by 148 P-51s were dispatched in a daylight raid against Osaka. While en route to
16435-523: The bombers from England to Germany and back. By the time the Pointblank offensive resumed in early 1944, matters had changed. Bomber escort defenses were initially layered, using the shorter-range P-38s and P-47s to escort the bombers during the initial stages of the raid before handing over to the P-51s when they were forced to turn for home. This provided continuous coverage during the raid. The Mustang
16608-413: The bombers had destroyed much of the country's six largest cities, killing between 112,000 and 126,762 people and rendering millions homeless. The widespread destruction and high number of casualties from these raids caused many Japanese to realize that their country's military was no longer able to defend the home islands. American losses were low compared to Japanese casualties; 136 B-29s were downed during
16781-602: The bombers proved to be easy prey for the Mustangs, and had to be quickly withdrawn from combat. The Focke-Wulf Fw 190 A, already suffering from poor high-altitude performance, was outperformed by the Mustang at the B-17's altitude, and when laden with heavy bomber-hunting weapons as a replacement for the more vulnerable twin-engined Zerstörer heavy fighters, it suffered heavy losses. The Messerschmitt Bf 109 had comparable performance at high altitudes, but its lightweight airframe
16954-532: The campaign. In Tokyo, Osaka, Nagoya, Yokohama, Kobe, and Kawasaki, "over 126,762 people were killed ... and a million and a half dwellings and over 105 square miles (270 km ) of urban space were destroyed." In Tokyo, Osaka and Nagoya, "the areas leveled (almost 100 square miles (260 km )) exceeded the areas destroyed in all German cities by both the American and British air forces (about 79 square miles (200 km ))." P-51s also conducted
17127-718: The central Illinois River valley, one third of all adults died as a result of violent injuries." The next major power in the region was the Illinois Confederation or Illini, a political alliance. Around the time of European contact in 1673, the Illinois confederation had an estimated population of over 10,000 people. As the Illini declined during the Beaver Wars era, members of the Algonquian -speaking Potawatomi , Miami , Sauk , and other tribes including
17300-409: The city of Chicago and its suburbs, and the adjoining exurban area into which the metropolis is expanding. As defined by the federal government, the Chicago metro area includes several counties in Illinois, Indiana , and Wisconsin , and has a population of over 9.8 million. Chicago itself is a cosmopolitan city, densely populated, industrialized, the transportation hub of the nation, and settled by
17473-535: The city, the Mustangs flew through thick clouds, and 27 of the fighters were destroyed in collisions. Nevertheless, 458 heavy bombers and 27 P-51s reached the city, and the bombardment killed 3,960 Japanese and destroyed 3.15 square miles (8.2 km ) of buildings. On 5 June, 473 B-29s struck Kobe by day and destroyed 4.35 square miles (11.3 km ) of buildings for the loss of 11 bombers. A force of 409 B-29s attacked Osaka again on 7 June; during this attack, 2.21 square miles (5.7 km ) of buildings were burnt out and
17646-514: The development of the American labor movement . From Sunday, October 8, 1871, until Tuesday, October 10, 1871, the Great Chicago Fire burned in downtown Chicago, destroying four sq mi (10 km ). At the turn of the 20th century, Illinois had a population of nearly 5 million. Many people from other parts of the country were attracted to the state by employment caused by the expanding industrial base. Whites were 98% of
17819-580: The earliest aircraft were obtained under Lend-Lease, all Mustang aircraft still on RAF charge at the end of the war were either returned to the USAAF "on paper" or retained by the RAF for scrapping. The last RAF Mustangs were retired from service in 1947. Prewar doctrine was based on the idea " the bomber will always get through ". Despite RAF and Luftwaffe experience with daylight bombing, the USAAF still incorrectly believed in 1942 that tightly packed formations of bombers would have so much firepower that they could fend off fighters on their own. Fighter escort
17992-471: The elements of the Illinois ANG are subject to being activated by order of the Governor to provide protection of life and property, and preserve peace, order and public safety. State missions include disaster relief in times of earthquakes, hurricanes, floods and forest fires, search and rescue, protection of vital public services, and support to civil defense. The Illinois Air National Guard consists of
18165-548: The end of Indian resistance to white settlement in the Chicago region. The Indians had been forced to leave their homes and move to Iowa in 1831; when they attempted to return, they were attacked and eventually defeated by U.S. militia . The survivors were forced back to Iowa. By 1832, when the last Indian lands in Illinois were ceded to the United States, the indigenous population of the state had been reduced by infectious diseases, warfare, and forced westward removal to only one village with fewer than 300 inhabitants. By 1839,
18338-408: The escorts, the threat of mass attacks and later the "company front" (eight abreast) assaults by armored Sturmgruppe Fw 190As brought an urgency to attacking the Luftwaffe wherever it could be found, either in the air or on the ground. Beginning in late February 1944 , 8th Air Force fighter units began systematic strafing attacks on German airfields with increasing frequency and intensity throughout
18511-619: The expected Allied invasion fleet. While the P-51 pilots only occasionally encountered Japanese fighters in the air, the airfields were protected by antiaircraft batteries and barrage balloons . By the end of the war, VII Fighter Command had conducted 51 ground-attack raids, of which 41 were considered successful. The fighter pilots claimed to have destroyed or damaged 1,062 aircraft and 254 ships, along with large numbers of buildings and railway rolling stock. American losses were 91 pilots killed and 157 Mustangs destroyed. Two P-51 pilots received
18684-536: The first American pilots to shoot down an Me 262, which he caught during its landing approach. On 7 October 1944, Lt. Urban L. Drew of the 361st Fighter Group shot down two Me 262s that were taking off, while on the same day, Lt. Col. Hubert Zemke , who had transferred to the Mustang-equipped 479th Fighter Group , shot down what he thought was a Bf 109, only to have his gun camera film reveal that it may have been an Me 262. On 25 February 1945, Mustangs of
18857-507: The first production aircraft by January 1941. In March 1940, 320 aircraft were ordered by Freeman, who had become the executive head of the Ministry of Aircraft Production (MAP) and the contract was promulgated on 24 April. The NA-73X , which was designed by a team led by lead engineer Edgar Schmued , followed the best conventional practice of the era, designed for ease of mass manufacturing. The design included several new features. One
19030-536: The first squadron of Mustang Mk Is entered service in January 1942, the first being No. 26 Squadron RAF . Due to poor high-altitude performance, the Mustangs were used by Army Co-operation Command , rather than Fighter Command, and were used for tactical reconnaissance and ground-attack duties. On 10 May 1942, Mustangs first flew over France, near Berck-sur-Mer . On 27 July 1942, 16 RAF Mustangs undertook their first long-range reconnaissance mission over Germany. During
19203-526: The flight velocities they achieved. Foremost among these were the Messerschmitt Me 163 B point-defense rocket interceptors, which started their operations with JG 400 near the end of July 1944, and the longer-endurance Messerschmitt Me 262 A jet fighter, first flying with the Gruppe -strength Kommando Nowotny unit by the end of September 1944. In action, the Me 163 proved to be more dangerous to
19376-555: The following major units: The Militia Act of 1903 established the present National Guard system, units raised by the states but paid for by the Federal Government, liable for immediate state service. If federalized by Presidential order, they fall under the regular military chain of command. On 1 June 1920, the Militia Bureau issued Circular No.1 on the organization of National Guard air units. The History of
19549-412: The full tank were made. Since the fuel from the fuselage tank was used during the initial stages of a mission, the fuel tank would be fitted in all Mustangs destined for VIII Fighter Command . The P-51 Mustang was a solution to the need for an effective bomber escort. It used a common, reliable engine and had internal space for a larger-than-average fuel load. With external fuel tanks, it could accompany
19722-468: The fuselage behind the pilot, greatly increasing the aircraft's range over that of the earlier P-51A. NAA incorporated the tank in the production of the P-51B-10, and supplied kits to retrofit it to all existing P-51Bs. The Mustang was initially developed for the RAF, which was its first user. As the first Mustangs were built to British requirements, these aircraft used factory numbers and were not P-51s;
19895-476: The ground, for a loss of eight Mustangs. At sea level, the Mustangs were able to outrun all enemy aircraft encountered. The RAF gained a significant performance enhancement at low altitude by removing or resetting the engine's manifold pressure regulator to allow overboosting, raising output as high as 1,780 horsepower at 70 in Hg. In December 1942, Allison approved only 1,570 horsepower at 60 in Hg manifold pressure for
20068-663: The jurisdiction of the Governor of Illinois through the office of the Illinois Adjutant General unless they are federalized by order of the President of the United States. The Illinois Air National Guard is headquartered at Camp Lincoln, Springfield, led by its Commander, Major General Daniel (Dan) McDonough; Chief of Staff, Brigadier General Kevin Jacobs; and Command Chief Master Sergeant Marlon Burton. Under
20241-572: The limited scale of operations, no conclusive evidence showed American doctrine was failing. In the 26 operations flown to the end of 1942, the loss rate had been under 2%. In January 1943, at the Casablanca Conference , the Allies formulated the Combined Bomber Offensive (CBO) plan for "round-the-clock" bombing – USAAF daytime operations complementing the RAF nighttime raids on industrial centers. In June 1943,
20414-468: The nation's railroad hub since the 1860s, and its O'Hare International Airport has been among the world's busiest airports for decades. Illinois has long been considered a microcosm of the United States and a bellwether in American culture, exemplified by the phrase Will it play in Peoria? . "Illinois" is the modern spelling for the early French Catholic missionaries and explorers' name for
20587-572: The neighboring country of Kuwait. This invasion brought a quick NATO response in the form of a massive military deployment to the Persian Gulf . By 7 August, the first U.S. troops were deployed to the Middle East in support of Operation Desert Shield . President George H. W. Bush called for limited reserve forces on 22 August, but did not activate Illinois National Guard units until September and November. The Illinois National Guard provided
20760-507: The north and center, and natural resources such as coal, timber, and petroleum in the south. Owing to its central location and favorable geography, the state is a major transportation hub : the Port of Chicago has access to the Atlantic Ocean through the Great Lakes and Saint Lawrence Seaway and to the Gulf of Mexico from the Mississippi River via the Illinois Waterway . Chicago has been
20933-631: The northern part of the state. The southern part of the state shipped food north, and this may have contributed to its name, " Little Egypt ", after the Biblical story of Joseph in Egypt supplying grain to his brothers. In 1832, the Black Hawk War was fought in Illinois and present-day Wisconsin between the United States and the Sauk , Fox (Meskwaki) , and Kickapoo Indian tribes. It represents
21106-468: The order comprised 320 NA-73s, followed by 300 NA-83s, all of which were designated Mustang Mark I by the RAF. The first RAF Mustangs supplied under Lend-Lease were 93 Mk Ia designated as P-51s by the USAAF, followed by 50 P-51As used as Mustang Mk IIs. Aircraft supplied to Britain under Lend-Lease were required for accounting purposes to be on the USAAC's books before they could be supplied to Britain, but
21279-459: The order had been placed; it first flew on 26 October 1940, 149 days into the contract, an uncommonly short development period even during the war. With test pilot Vance Breese at the controls, the prototype handled well and accommodated an impressive fuel load. The aircraft's three-section, semi-monocoque fuselage was constructed entirely of aluminum to save weight. It was armed with four .30 caliber (7.62 mm) AN/M2 Browning machine guns in
21452-399: The population of Illinois was 12,812,508 in the 2020 United States census , moving from the fifth-largest state to the sixth-largest state (losing out to Pennsylvania). Illinois' population slightly declined in 2020 from the 2010 United States census by just over 18,000 residents and the overall population was quite higher than recent census estimates. Illinois is the most populous state in
21625-470: The promising outlook of a Merlin Mustang, along with the subsequent work in progress by Rolls Royce on the Mustang X, NAA representatives including Mustang designer Schmued visited the UK to examine and discuss the project in detail. The promising calculations and modification progress by Rolls Royce led in July 1942 to a contract being let for two NAA Merlin prototypes, briefly designated XP-78, but soon to become
21798-497: The resulting detailed design drawings, signing the commencement of the Mustang project on 4 May 1940, and firmly ordering 320 on 29 May 1940. Prior to this, NAA only had a letter of intent for an order of 320 aircraft. Curtiss engineers accused NAA of plagiarism. The British Purchasing Commission stipulated armament of four .303 in (7.7 mm) machine guns (as used on the Tomahawk), a unit cost of no more than $ 40,000, and delivery of
21971-503: The revolutionary Illinois campaign prefigured American involvement in the region. Following U.S. independence in 1783 , which made the Mississippi River the national boundary, American settlers began arriving from Kentucky via the Ohio River. Illinois was soon part of the United States' oldest territory, the Northwest Territory , and in 1818 it achieved statehood . The Erie Canal brought increased commercial activity in
22144-467: The second aircraft of this batch to help develop the P-51A. The Allison engine in the Mustang I had a single-stage supercharger that caused power to drop off rapidly above 15,000 feet (4,600 m). This made it unsuitable for use at the altitudes where combat was taking place in Europe. Allison's attempts at developing a high-altitude engine were underfunded, but produced the V-1710-45, which featured
22317-596: The second-most populous urban area in Illinois with over 700,000 residents. Other major urban areas include the Peoria metropolitan area , Rockford metropolitan area , Champaign–Urbana metropolitan area (home to the University of Illinois ), Springfield metropolitan area , the Illinois portion of the Quad Cities area, and the Bloomington–Normal metropolitan area . The United States Census Bureau found that
22490-431: The single-stage Allison, driving a four-bladed Hamilton Standard propeller, required moving the wing slightly forward to correct the aircraft's center of gravity . After the USAAF, in July 1943, directed fighter aircraft manufacturers to maximize internal fuel capacity, NAA calculated the P-51B's center of gravity to be forward enough to include an additional 85 US gal (320 L; 71 imp gal) fuel tank in
22663-423: The southern tip of Lake Michigan. Such a boundary would have left Illinois with no shoreline on Lake Michigan at all. However, as Indiana had successfully been granted a 10 mi (16 km) northern extension of its boundary to provide it with a usable lakefront, the original bill for Illinois statehood, submitted to Congress on January 23, 1818, stipulated a northern border at the same latitude as Indiana's, which
22836-402: The southern tip to around 35 in (889 mm) in the northern portion of the state. Normal annual snowfall exceeds 38 in (965 mm) in the Chicago area, while the southern portion of the state normally receives less than 14 in (356 mm). The all-time high temperature was 117 °F (47 °C), recorded on July 14, 1954, at East St. Louis , and the all-time low temperature
23009-578: The spring, with the objective of gaining air supremacy over the Normandy battlefield. In general, these were conducted by units returning from escort missions, but beginning in March, many groups also were assigned airfield attacks instead of bomber support. The P-51, particularly with the advent of the K-14 gyro gunsight and the development of "Clobber Colleges" for the training of fighter pilots in fall 1944,
23182-432: The state at the confluence of the Mississippi and Ohio Rivers, served as a strategically important supply base and training center for the Union army. For several months, both General Grant and Admiral Foote had headquarters in Cairo. During the Civil War, and more so afterwards, Chicago's population skyrocketed, which increased its prominence. The Pullman Strike and Haymarket Riot , in particular, greatly influenced
23355-407: The state capital; Quincy ; Decatur ; Bloomington-Normal ; and Champaign - Urbana . The third division is Southern Illinois , comprising the area south of U.S. Route 50 , including Little Egypt , near the juncture of the Mississippi River and Ohio River . Southern Illinois is the site of the ancient city of Cahokia , as well as the site of the first state capital at Kaskaskia , which today
23528-438: The state's population. Bolstered by continued immigration from southern and eastern Europe , and by the African-American Great Migration from the South, Illinois grew and emerged as one of the most important states in the union. By the end of the century, the population had reached 12.4 million. The Century of Progress World's fair was held at Chicago in 1933. Oil strikes in Marion County and Crawford County led to
23701-419: The state, including the lead mining region near Galena . More importantly, it added nearly 50 miles of Lake Michigan shoreline and the Chicago River. Pope and others envisioned a canal that would connect the Chicago and Illinois rivers and thus connect the Great Lakes to the Mississippi. In 1818, Illinois became the 21st U.S. state. The capital remained at Kaskaskia, headquartered in a small building rented by
23874-422: The state. In 1819, Vandalia became the capital, and over the next 18 years, three separate buildings were built to serve successively as the capitol building. In 1837, the state legislators representing Sangamon County , under the leadership of state representative Abraham Lincoln , succeeded in having the capital moved to Springfield , where a fifth capitol building was constructed. A sixth capitol building
24047-448: The state. The Tri-State Tornado of 1925 killed 695 people in three states; 613 of the victims died in Illinois. Chicago is the largest city in the state and the third-most populous city in the United States, with a population of 2,746,388 in 2020. Furthermore, over 7 million residents of the Chicago metropolitan area reside in Illinois. The U.S. Census Bureau currently lists seven other cities with populations of over 100,000 within
24220-421: The state. This includes the Chicago satellite towns of Aurora , Joliet , Naperville , and Elgin , as well as the cities of Rockford , the most populous city in the state outside of the Chicago area; Springfield , the state's capital; and Peoria . The most populated city in the state south of Springfield is Belleville , with 42,000 residents. It is located in the Metro East region of Greater St. Louis ,
24393-411: The superiority of the wing designed with the NAA/NACA 45–100 airfoils . The other feature was a new cooling arrangement positioned aft (single ducted water and oil radiators assembly) that reduced the fuselage drag and effects on the wing. Later, after much development, they discovered that the cooling assembly could take advantage of the Meredith effect , in which heated air exited the radiator with
24566-417: The test results and after further flights by a number of USAAF pilots, the results were so positive that North American began work on converting several aircraft developing into the P-51B/C (Mustang Mk III) model, which became the first long range fighter to be able to compete with the Luftwaffe 's fighters. The definitive version, the P-51D , was powered by the Packard V-1650-7 , a license-built version of
24739-473: The theater. Since that mobilization, smaller numbers of wing personnel and aircraft have continually supported Operations Enduring Freedom and Iraqi Freedom. On 28 December 2003, a 182nd AW crew delivered earthquake relief supplies to Iran, becoming the first U.S. aircraft to land there since 1981. The 183rd FW conducted numerous overseas deployments, including six to Southwest Asia/Iraq, two to Denmark , one to Panama , one to Curaçao , and one to Thailand . As
24912-417: The time the crisis was under control in the early fall, over 700 personnel from the 126th Air Refueling Wing and assigned units had pulled duty in the flood ravaged towns. In 1996, the 182nd AW wing began participation in ongoing flying missions for Operation Joint Endeavor in Bosnia . After the September 11 attacks 2001, Illinois ANG members were called up to support the USAF at various locations around
25085-446: The two-speed, two-stage- supercharged Merlin 66 , and was armed with six .50 caliber (12.7 mm) AN/M2 Browning machine guns . From late 1943, P-51Bs and P-51Cs (supplemented by P-51Ds from mid-1944) were used by the USAAF's Eighth Air Force to escort bombers in raids over Germany , while the RAF's Second Tactical Air Force and the USAAF's Ninth Air Force used the Merlin-powered Mustangs as fighter-bombers, roles in which
25258-469: The war in Europe wound down, the P-51 became more common. With the capture of Iwo Jima , USAAF P-51 Mustang fighters of the VII Fighter Command were stationed on that island starting in March 1945, being initially tasked with escorting Boeing B-29 Superfortress missions against the Japanese homeland . The command's last major raid of May was a daylight incendiary attack on Yokohama on 29 May conducted by 517 B-29s escorted by 101 P-51s. This force
25431-424: The waterways of the Illinois area for thousands of years before the arrival of Europeans. The Koster Site has been excavated and demonstrates 7,000 years of continuous habitation. Cahokia , the largest regional chiefdom and Urban Center of the Pre-Columbian Mississippian culture , was located near present-day Collinsville, Illinois . They built an urban complex of more than 100 platform and burial mounds ,
25604-414: The west and quickly improved their battle direction. In fall 1943, the 8th Air Force's heavy bombers conducted a series of deep-penetration raids into Germany, beyond the range of escort fighters. The Schweinfurt–Regensburg mission in August lost 60 B-17s of a force of 376, the 14 October attack lost 77 of a force of 291—26% of the attacking force. For the US, the very concept of self-defending bombers
25777-408: The wings and two .50 caliber (12.7 mm) AN/M2 Browning machine guns mounted under the engine and firing through the propeller arc using a gun-synchronizing gear . While the USAAC could block any sales it considered detrimental to the interests of the US, the NA-73 was considered to be a special case because it had been designed at the behest of the British and all dealings were directly between
25950-650: The world. During a September 2002 deployment to Oman , 182nd AW aircraft flew combat supply missions into Afghanistan for Operation Enduring Freedom . On 29 March 2003, SSgt Jacob Frazier of the 169th Air Support Operations Squadron was killed in action while serving with United States Army Special Forces in Afghanistan. He was the first member of the 182nd AW to die in combat. In March 2003, immediately following mobilization, six Illinois ANG C-130 aircraft and over 350 personnel were deployed to Minhad, United Arab Emirates , for Operation Iraqi Freedom . These airmen returned in August after providing airlift support throughout
26123-455: Was Illinois's largest city. With the tremendous growth of mines and factories in the state in the 19th century, Illinois was the ground for the formation of labor unions in the United States . In 1847, after lobbying by Dorothea L. Dix , Illinois became one of the first states to establish a system of state-supported treatment of mental illness and disabilities, replacing local almshouses . Dix came into this effort after having met J. O. King,
26296-459: Was a decisive element in Allied countermeasures against the Jagdverbände . The numerical superiority of the USAAF fighters, superb flying characteristics of the P-51, and pilot proficiency helped cripple the Luftwaffe ' s fighter force. As a result, the fighter threat to the US, and later British, bombers was greatly diminished by July 1944. The RAF, long proponents of night bombing for protection, were able to reopen daylight bombing in 1944 as
26469-467: Was a low priority, but when the concept was discussed in 1941, the Lockheed P-38 Lightning was considered to be most appropriate, as it had the speed and range. Another school of thought favored a heavily up-armed "gunship" conversion of a strategic bomber . A single-engined, high-speed fighter with the range of a bomber was thought to be an engineering impossibility. The 8th Air Force started operations from Britain in August 1942. At first, because of
26642-468: Was a wing designed using laminar flow airfoils, which were developed co-operatively by NAA and the National Advisory Committee for Aeronautics (NACA). These airfoils generated low drag at high speeds. During the development of the NA-73X, a wind-tunnel test of two wings, one using NACA five-digit airfoils and the other using the new NAA/NACA 45–100 airfoils, was performed in the University of Washington Kirsten Wind Tunnel. The results of this test showed
26815-415: Was adopted in 1970, replacing the 1870 document. The first Farm Aid concert was held in Champaign to benefit American farmers, in 1985. The worst upper Mississippi River flood of the century, the Great Flood of 1993 , inundated many towns and thousands of acres of farmland. Illinois entered the 21st century under Republican Governor George Ryan . Near the end of his term in January 2003, following
26988-415: Was also one of the first aircraft to have a fuselage lofted mathematically using conic sections ; this resulted in smooth, low-drag surfaces. To aid production, the airframe was divided into five main sections—forward, center, rear fuselage, and two wing halves— all of which were fitted with wiring and piping before being joined. The prototype NA-73X was rolled out in September 1940, just 102 days after
27161-409: Was an early claimant to much of Illinois. The Illinois Territory was created on February 3, 1809, with its capital at Kaskaskia , an early French settlement. During the discussions leading up to Illinois's admission to the Union , the proposed northern boundary of the state was moved twice. The original provisions of the Northwest Ordinance had specified a boundary that would have been tangent to
27334-419: Was born and raised in the state. Illinois honors Lincoln with its official state slogan Land of Lincoln . The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago. Illinois has a highly diverse economy , with the global city of Chicago in the northeast, major industrial and agricultural hubs in
27507-406: Was called into question, but instead of abandoning daylight raids and turning to night bombing, as the RAF suggested, they chose other paths; at first, bombers converted to gunships (the Boeing YB-40 ) were believed to be able to escort the bomber formations, but when the concept proved to be unsuccessful, thoughts then turned to the Lockheed P-38 Lightning. In early 1943, the USAAF also decided that
27680-506: Was disbanded on 1 May 1944. On 24 May 1946, the United States Army Air Forces , in response to dramatic postwar military budget cuts imposed by President Harry S. Truman , allocated inactive unit designations to the National Guard Bureau for the formation of an Air Force National Guard. These unit designations were allotted and transferred to various State National Guard bureaus to provide them unit designations to re-establish them as Air National Guard units. Led by Lt.Col. Ralph Pickering,
27853-442: Was erected in 1867, which continues to serve as the Illinois capitol today. Though it was ostensibly a " free state ", there was nonetheless slavery in Illinois . The ethnic French had owned black slaves since the 1720s, and American settlers had already brought slaves into the area from Kentucky . Slavery was nominally banned by the Northwest Ordinance, but that was not enforced for those already holding slaves. When Illinois became
28026-401: Was even more greatly affected by increases in armament. The Mustang's much lighter armament, tuned for antifighter combat, allowed it to overcome these single-engined opponents. At the start of 1944, Major General James Doolittle , the new commander of the 8th Air Force, released most fighters from the requirement of flying in close formation with the bombers, allowing them free rein to attack
28199-424: Was fitted to all Mustang X prototypes. Initially, the Mustang's steadfast champion, USAAC/F Assistant Air Attaché Major Thomas Hitchcock, was concerned that the USAAF had little or no interest in the potential of the P-51A and its development with the Merlin engine. He wrote: "Its development in this theatre has suffered for various reasons. Sired by the English out of an American mother, the Mustang has no parent in
28372-415: Was granted to the 170th Fighter Squadron , the precursor to the 183d Fighter Wing, with 60 men meeting Thursday nights at the State Armory. During the Korean War , the 170th Fighter Squadron was ordered to federal duty for 21 months on 1 March 1951. Ten days later, the squadron deployed to Bergstrom Air Force Base , Texas . In April the unit was re-designated the 170th Fighter Bomber Squadron. On 31 July,
28545-410: Was intercepted by 150 A6M Zero fighters, sparking an intense air battle in which five B-29s were shot down and another 175 damaged. In return, the P-51 pilots claimed 26 "kills" and 23 "probables" for the loss of three fighters. The 454 B-29s that reached Yokohama struck the city's main business district and destroyed 6.9 square miles (18 km ) of buildings; over 1000 Japanese were killed. Overall,
28718-453: Was running at capacity, so P-40s were in short supply. North American Aviation (NAA) was already supplying its T-6 Texan (known in British service as the "Harvard") trainer to the RAF, but was otherwise underused. NAA President "Dutch" Kindelberger approached Self to sell a new medium bomber , the North American B-25 Mitchell . Instead, Self asked if NAA could manufacture P-40s under license from Curtiss. Kindelberger said NAA could have
28891-425: Was shot down and killed by friendly fire on Christmas Day 1944 during the Battle of the Bulge . In early 1945, P-51C, D, and K variants also joined the Chinese Nationalist Air Force . These Mustangs were provided to the 3rd, 4th, and 5th Fighter Groups and used to attack Japanese targets in occupied areas of China. The P-51 became the most capable fighter in China, while the Imperial Japanese Army Air Force used
29064-443: Was so clearly superior to earlier US designs that the 8th Air Force began to steadily switch its fighter groups to the Mustang, first swapping arriving P-47 groups to the 9th Air Force in exchange for those that were using P-51s, then gradually converting its Thunderbolt and Lightning groups. By the end of 1944, 14 of its 15 groups flew Mustangs. The Luftwaffe's twin-engined Messerschmitt Bf 110 heavy fighters brought up to deal with
29237-415: Was submerged beneath a shallow sea and located near the Equator. Diverse marine life lived at this time, including trilobites , brachiopods , and crinoids . Changing environmental conditions led to the formation of large coal swamps in the Carboniferous . Illinois was above sea level for at least part of the Mesozoic , but by its end was again submerged by the Western Interior Seaway . This receded by
29410-541: Was to keep the Mustangs away from the Fw 190s as they attacked the bombers. This strategy proved to be problematic, as the large German formation took a long time to assemble and was difficult to maneuver. It was often intercepted by the P-51 "fighter sweeps" before it could attack the bombers. However, German attacks against bombers could be effective when they did occur; the bomber-destroyer Fw 190As swept in from astern and often pressed their attacks to within 90 m (100 yd). While not always able to avoid contact with
29583-614: Was topped by a structure thought to have measured about 105 ft (32 m) in length and 48 ft (15 m) in width, covered an area 5,000 sq ft (460 m ), and been as much as 50 ft (15 m) high, making its peak 150 ft (46 m) above the level of the plaza. The finely crafted ornaments and tools recovered by archaeologists at Cahokia include elaborate ceramics, finely sculptured stonework, carefully embossed and engraved copper and mica sheets, and one funeral blanket for an important chief fashioned from 20,000 shell beads. These artifacts indicate that Cahokia
29756-443: Was truly an urban center, with clustered housing, markets, and specialists in toolmaking, hide dressing, potting, jewelry making, shell engraving, weaving and salt making. The civilization vanished in the 15th century for unknown reasons, but historians and archeologists have speculated that the people depleted the area of resources. Many indigenous tribes engaged in constant warfare. According to Suzanne Austin Alchon, "At one site in
29929-436: Was −38 °F (−39 °C), recorded on January 31, 2019, during the January 2019 North American cold wave at a weather station near Mount Carroll , and confirmed on March 5, 2019. This followed the previous record of −36 °F (−38 °C) recorded on January 5, 1999, near Congerville . Prior to the Mount Carroll record, a temperature of −37 °F (−38 °C) was recorded on January 15, 2009, at Rochelle , but at
