[57] The B-17E was an extensive revision of the Model 299 design: The fuselage was extended by 10ft (3.0m); a much larger rear fuselage, vertical tailfin, rudder, and horizontal stabilizer were added; a gunner's position was added in the new tail;[note 4] the nose (especially the bombardier's framed, 10-panel nose glazing) remained relatively the same as the earlier B through D versions had; a Sperry electrically powered manned dorsal gun turret just behind the cockpit was added; a similarly powered (also built by Sperry) manned ventral ball turret just aft of the bomb bay replaced the relatively hard-to-use, Sperry model 645705-D[60] remotely operated ventral turret on the earliest examples of the E variant. The B-17 Flying Fortress became symbolic of the United States of America's air power. The B-17's greatest success in the Pacific was in the Battle of the Bismarck Sea, in which aircraft of this type were responsible for damaging and sinking several Japanese transport ships. M/SGT Michael Arooth shot down 17 enemy aircraft to reach triple "Ace" status. [20] The YB-17 incorporated a number of significant changes from the Model 299, including more powerful Wright R-1820-39 Cyclone engines. Wixley, Ken. Wagner, Ray, "American Combat Planes of the 20th Century", Reno, Nevada, 2004, Jack Bacon & Company, This page was last edited on 24 February 2023, at 16:26. In 1942, when Eighth Air Force heavy bombers based in Britain first went operational in Europe, they mostly flew what were termed "milk runs" over France, accompanied by fighter escorts. The idea of a pilot's checklist spread to other crew members, other air corps aircraft types, and eventually throughout the aviation world. As many as half a million civilians remained in Stalingrad when the Germans approached in the late summer of 1942. One of the two "E" Flying Fortresses was photographed late in the war by U. S. aerial recon. Gr. The bomber's topside surfaces were repainted a dark olive drab, but retained its light gray under wing and lower fuselage surfaces. The most famous B-17, the Memphis Belle, toured the U. S. with her crew to reinforce national morale (and to sell war bonds). The adoption of the 21 cm Nebelwerfer-derived Werfer-Granate 21 (Wfr. Nonetheless, this deed made him a celebrated war hero. The 19th Bombardment Group had deployed to Clark Field in the Philippines a few weeks before the Japanese attack on Pearl Harbor as the first of a planned heavy bomber buildup in the Pacific. [160][168] PB-1Ws continued in USN service until 1955, gradually being phased out in favor of the Lockheed WV-2 (known in the USAF as the EC-121, a designation adopted by the USN in 1962), a military version of the Lockheed 1049 Constellation commercial airliner. [158][159] Strategic Air Command (SAC), established in 1946, used reconnaissance B-17s (at first called F-9 [F for Fotorecon], later RB-17) until 1949. [149] Others, with the cover designations Dornier Do 200 and Do 288, were used as long-range transports by the Kampfgeschwader 200 special duties unit, carrying out agent drops and supplying secret airstrips in the Middle East and North Africa. There are very few films left in existence showing the Me 262 in action, especially shooting down allied bombers with P-51 escorts. 206 Squadron RAF sank U-627 on 27 October 1942, the first of 11 U-boat kills credited to RAF Fortress bombers during the war.[86]. [221] Both films were made with the full cooperation of the United States Army Air Forces and used USAAF aircraft and (for Twelve O'Clock High) combat footage. Tora! [42] Improved with larger flaps and rudder and a well-framed, 10-panel plexiglas nose, the B-17Bs were delivered in five small batches between July 1939 and March 1940. [ Via] B17f-42-30336 landed in a field at Norholm Estate near Varde Denmark on 9.10.1943 after developing engine trouble, the crew baled out and the pilot landed the plane . Frisbee, John L. "Valor: Rabaul on a Wing and a Prayer". [112], On 7 December 1941, a group of 12 B-17s of the 38th (four B-17C) and 88th (eight B-17E) Reconnaissance Squadrons, en route to reinforce the Philippines, was flown into Pearl Harbor from Hamilton Field, California, arriving while the surprise attack on Pearl Harbor was going on. The B-17 evolved through numerous design advances[4][5] but from its inception, the USAAC (later, the USAAF) promoted the aircraft as a strategic weapon. This. It carried Swiss national white cross insignia in red squares on both sides of its rudder, fuselage sides, and on the topside and underside wings. An overwhelming majority of them were women and children. [105] German fighters needed to respond, and the North American P-51 Mustang and Republic P-47 Thunderbolt fighters (equipped with improved drop tanks to extend their range) accompanying the American heavies all the way to and from the targets engaged them. This articleis part of an ongoing series commemorating the 75th anniversary of the end of World War II made possible by Bank of America. [115] When the FEAF received word of the attack on Pearl Harbor, General Lewis H. Brereton sent his bombers and fighters on various patrol missions to prevent them from being caught on the ground. [107][108], A third raid on Schweinfurt on 24 February 1944 highlighted what came to be known as "Big Week",[109] during which the bombing missions were directed against German aircraft production. He also broke the west-to-east coast record on the return trip, averaging 245mph (394km/h) in 11 hours 1 minute. Britain in WW2 . Serial number 44-85784 is the last airworthy B-17 in the United Kingdom and is based at the Imperial War Museum Duxford. [92], The U.S. did not offer B-17s to the Soviet Union as part of its war materiel assistance program, but at least 73 aircraft were acquired by the Soviet Air Force. The Americans, on the other hand, were proponents of daylight, precision bombing using their state-of-the-art and top-secret Norden bomb-sight. Swiss aircraft attempted to intercept and force individual aircraft to land, interning their crews; one Swiss pilot was killed, shot down by a U.S. bomber crew in September 1944. The only prototype XB-38 to fly crashed on its ninth flight, and the type was abandoned. Its famous nickname came from the fact it carried 13 .50 caliber M2 Browning machine guns for protection, and had a legendary toughness for carrying its crew home on one engine or even with the tail shot away. [20] While the air corps was still enthusiastic about the aircraft's potential, army officials were daunted by its cost;[24] Douglas quoted a unit price of $58,200 (equivalent to $916,000 in 2021) based on a production order of 220 aircraft, compared with $99,620 (equivalent to $1,568,000 in 2021 ) from Boeing. [150][151] One B-17 of KG200, bearing the Luftwaffe's KG 200 Geschwaderkennung (combat wing code) markings A3+FB, was interned by Spain when it landed at Valencia airfield, 27 June 1944, remaining there for the rest of the war. The Air Corps was looking for a bomber capable of reinforcing the air forces in Hawaii, Panama, and Alaska. [note 1] Boeing also claimed in some of the early press releases that Model 299 was the first combat aircraft that could continue its mission if one of its four engines failed. Japanese fighter pilots machine-gunned some of the B-17 crew members as they descended and attacked others in the water after they landed. Ramsey, Winston G. "The V-Weapons". The B-17 finally had a fighter which could escort them in and out of Germany, and began to overwhelm German defenses and industry. 0. How many b17 are still flying? [14] The most distinct mount was in the nose, which allowed the single machine gun to be fired toward nearly all frontal angles. They were brave. It was a very effective weapons system, dropping more bombs during the . [citation needed] It was subsequently used in various films and in the 1960s television show 12 O'Clock High before being retired to the Planes of Fame aviation museum in Chino, California. Gift of Peggy Wallace, 2010.308.044, Group of B-17 bombers over Europe with vapor trail flowing behind them, 1944-45. [85] These were augmented starting in July 1942 by 45 Fortress Mk IIA (B-17E) followed by 19 Fortress Mk II (B-17F) and three Fortress Mk III (B-17G). A merica joined Britain's strategic air campaign designed to destroy Nazi Germany's industrial capacity soon after her entrance into World War Two. [30] One suggestion adopted was the use of a preflight checklist to avoid accidents such as that which befell the Model 299. Also, the Y1B-17A's new service ceiling was more than 2 miles (3.2km) higher at 38,000 feet (12,000m), compared to the Y1B-17's 27,800 feet (8,500m). [138][139][140] Wally Hoffman, a B-17 pilot with the Eighth Air Force during World WarII, said, "The plane can be cut and slashed almost to pieces by enemy fire and bring its crew home. Clearly, something had to be done because the bomber was not getting through. Of 2,900 men in the crews, about 650 did not return, although some survived as prisoners of war. "[141] Martin Caidin reported one instance in which a B-17 suffered a midair collision with a Focke-Wulf Fw 190, losing an engine and suffering serious damage to both the starboard horizontal stabilizer and the vertical stabilizer, and being knocked out of formation by the impact. Quote: "At the peak of production, Boeing was rolling out as many as 363 B-17s a month, averaging between 14 and 16 Forts a day, the most incredible production rate for large aircraft in aviation history." 945 Magazine Street, New Orleans, LA 70130 [1][13] The day before, Richard Williams, a reporter for The Seattle Times, coined the name "Flying Fortress" when observing the large number of machine guns sticking out from the new airplane he described it as a "15-ton flying fortress" in a picture caption. Frisbee, John L. "Valor: The Right Touch". Still, the Air Corps ordered 13 more B-17s for further evaluation, then introduced it into service in 1938. Initially, it could carry a payload of 2200 kg along with 5x .30-inch machine guns. [144], After examining wrecked B-17s and B-24s, Luftwaffe officers discovered that on average it took about 20 hits with 20 mm shells fired from the rear to bring them down. The first Eighth Air Force units arrived in High Wycombe, England, on 12 May 1942, to form the 97th Bomb Group. [180], Many B-17 crew members received military honors and 17 received the Medal of Honor, the highest military decoration awarded by the United States:[197], Data from The Encyclopedia of World Aircraft[38], Hollywood featured the B-17 in its period films, such as director Howard Hawks' Air Force starring John Garfield and Twelve O'Clock High starring Gregory Peck. The plane was pulled out of front-line service and used as a transport plane and even drones. The B-17F variants were the primary versions flying for the Eighth Air Force to face the Germans in 1943 and had standardized the manned Sperry ball turret for ventral defense, also replacing the earlier, 10-panel framed bombardier's nose glazing from the B subtype with an enlarged, nearly frameless Plexiglas bombardier's nose enclosure for improved forward vision. Army Air Forces. coast. On landing, the aircraft overran the runway and ran into a ditch, where it was then strafed. [135] In order to more quickly form these formations, assembly ships, planes with distinctive paint schemes, were utilized to guide bombers into formation, saving assembly time. As he maneuvered his unarmed B-17 bomber over the island of Oahu, U.S. Army Lt. Robert Thacker was puzzled. This led to more widespread conversion of B-17s as drones and drone control aircraft, both for further use in atomic testing and as targets for testing surface-to-air and air-to-air missiles. Although the conversion was not complete until mid-1943, B-17 combat operations in the Pacific theater came to an end after a little over a year. 504-528-1944, Jenny Craig Institute for the Study of War and Democracy, Black Volunteer Infantry Platoons in World War II, Kasserine Pass: German Offensive, American Victory, Gallantry against Great Odds: LTC George Marshall and Operation RESERVIST, Prelude to Liberation: Genesis of American Amphibious Assault in the ETO, Black Thursday October 14, 1943: The Second Schweinfurt Bombing Raid, An Exercise in Depravity: The Establishment of the Warsaw Ghetto, Unsung Witnesses of the Battle of Stalingrad, Stalingrad: Experimentation, Adaptation, Implementation. Wiki User. "Operation Pointblank: Evolution of Allied Air Doctrine During World WarII". Instead of building models based on experimental engineering, Boeing had been hard at work developing their bomber and now had versions ready for production far better than would have been possible otherwise. Forty-five planes survive in complete form [1] [a], including 38 in the United States. Four B-17s were shot down in these operations.[171]. [75], Three damaged B-17s, one "D" and two "E" series, were rebuilt during 1942 to flying status by Japanese technicians and mechanics, using parts salvaged from abandoned B-17 wrecks in the Philippines and the Java East Indies. The Name In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. National Archives and Records Administration - ARC Identifier 2870 / Local Identifier 18-C-406-2 - AIR WAR IN EUROPE - War Department. Unlike the fighter pilots, individual bomber gunners did not receive official credit for any of their shootdowns. Gift of Peggy Wallace, 2010.308.040. These aircraft had landed with mechanical trouble during the shuttle bombing raids over Germany or had been damaged by a Luftwaffe raid in Poltava. Also on board were Wright Field test observer John Cutting, and mechanic Mark Koegler. How many b17s were shot down? 7071, 83, 92, 256, 26869. Major General Frank Maxwell Andrews of the GHQ Air Force believed that the capabilities of large four-engined aircraft exceeded those of shorter-ranged, twin-engined aircraft, and that the B-17 was better suited to new, emerging USAAC doctrine. All of these modifications made the YB-40 well over 10,000lb (4,500kg) heavier than a fully loaded B-17F. The first bomber to hit Japan after Pearl Harbor, the B-25 Mitchell was found in every theater of the war and was a rugged, multipurpose bomber beloved by her aircrew for its survivability and ease to fly. ", "Second-Generation Norden Bombsight Vault", "Aviation Photography: B-17 Flying Fortress. [176] In a well-publicized mission on 12 May of the same year, three Y1B-17s "intercepted" and took photographs of the Italian ocean liner SS Rex 610 miles (980km) off the Atlantic coast. (U.S. Air Force photo) The Boeing B-17 was one of the primary heavy bombers built by the United States during World War II. [136][137] Luftwaffe fighter pilots likened attacking a B-17 combat box formation to encountering a fliegendes Stachelschwein, "flying porcupine", with dozens of machine guns in a combat box aimed at them from almost every direction. With its usual nose-mounted armament of four MK 108 cannons, and with some examples later equipped with the R4M rocket, launched from underwing racks, it could fire from outside the range of the bombers' .50in (12.7mm) defensive guns and bring an aircraft down with one hit,[147] as both the MK 108's shells and the R4M's warheads were filled with the "shattering" force of the strongly brisant Hexogen military explosive. [21] Doyle notes, "The loss of Hill and Tower, and the Model 299, was directly responsible for the creation of the modern written checklist used by pilots to this day. Arriving over the target, LeMay's bombers encountered little flak and were able to place approximately 300 tons . In 1964, the latter film was made into a television show of the same name and ran for three years on ABC TV. General Ira C. Eaker and the Eighth Air Force placed highest priority on attacks on the German aircraft industry, especially fighter assembly plants, engine factories, and ball-bearing manufacturers. Brereton planned B-17 raids on Japanese airfields in Formosa, in accordance with Rainbow 5 war plan directives, but this was overruled by General Douglas MacArthur. Meantime 60 B-17's were lost to all causes (including flak). No traces of the 3 captured Flying Fortresses were ever found in Japan by Allied occupation forces. How many helicopters were shot down in Vietnam? [11] It combined features of the company's experimental XB-15 bomber and 247 transport. [84], As use by Bomber Command had been curtailed, the RAF transferred its remaining FortressI aircraft to Coastal Command for use as a long-range maritime patrol aircraft. For other uses, see, "Flying Fortress" redirects here. ", "Why Use Colourful Camouflage in World War 2? ", Frisbee, John L. "Valor: A Point of Honor. [155], Official Swiss records identify 6,501 airspace violations during the course of the war, with 198 foreign aircraft landing on Swiss territory and 56 aircraft crashing there. [67], By the time the definitive B-17G appeared, the number of guns had been increased from seven to 13, the designs of the gun stations were finalized, and other adjustments were completed. [91], The USAAF began building up its air forces in Europe using B-17Es soon after entering the war. In early 1942, the 7th Bombardment Group began arriving in Java with a mixed force of B-17s and LB-30/B-24s. in 1970, and in Memphis Belle with Matthew Modine, Eric Stoltz, Billy Zane, and Harry Connick Jr. in 1990. [36] Experiments on this aircraft led to the use of a quartet of General Electric turbo-superchargers, which later became standard on the B-17 line. . The B-17 was reported as shot down by observers, but it survived and brought its crew home without injury. Although the prototype was company-owned and never received a military serial (the B-17 designation itself did not appear officially until January 1936, nearly three months after the prototype crashed),[29] the term "XB-17" was retroactively applied to the NX13372's airframe and has entered the lexicon to describe the first Flying Fortress. [16] On 20 August 1935, the prototype flew from Seattle to Wright Field in nine hours and three minutes with an average cruising speed of 252 miles per hour (406km/h), much faster than the competition. Those who survived the initial onslaught and did not manage to flee, had to eke out a living on a battleground ravaged by incessant bombardment and street fighting. 21) rocket mortar by the Luftwaffe in mid-August 1943 promised the introduction of a major "stand-off" style of offensive weapon one strut-mounted tubular launcher was fixed under each wing panel on the Luftwaffe's single-engine fighters, and two under each wing panel of a few twin-engine Bf 110 daylight Zerstrer aircraft. The B-17, for all its armor and firepower, was simply unable to continue to fly unescorted against swarms of German fighter aircraft and their sophisticated air defense system. [12] [223][224] Works such as The Death of the Ball Turret Gunner by Randall Jarrell and Heavy Metal's section "B-17" depict the nature of these missions. In October 1943 the Swiss interned Boeing B-17F-25-VE, tail number 25841, and its U.S. flight crew after the Flying Fortress developed engine trouble after a raid over Germany and was forced to land. [105] The 8th Air Force alone lost 176 bombers in October 1943,[106] and was to suffer similar casualties on 11 January 1944 on missions to Oschersleben, Halberstadt, and Brunswick. No products in the cart. [57] The B-17's turbocharged Wright R-1820 Cyclone 9 engines were upgraded to increasingly more powerful versions of the same powerplants throughout its production, and similarly, the number of machine gun emplacement locations was increased.[61]. To enhance performance at slower speeds, the B-17B was altered to include larger rudders and flaps. B-17 Flying Fortresses of the 398th Bombardment Group, 8th Air Force, taking fire from flak over Germany, 1944-45. Moreover, German fighter aircraft later developed the tactic of high-speed strafing passes rather than engaging with individual aircraft to inflict damage with minimum risk. Work on using B-17s to carry airborne lifeboats had begun in 1943, but they entered service in the European theater only in February 1945. Water spouts just offshore . The 4x Hornet Radial Engines could produce 750 HP at 2100 meters. During World War II, the B-17 equipped 32 overseas combat groups, inventory peaking in August 1944 at 4,574 USAAF aircraft worldwide. It was code-named "Tachikawa 105" after the mystery aircraft's wingspan was measured (104-ft.) but never identified. One of these Taiwan-based B-17s was flown to Clark Air Base in the Philippines in mid-September, assigned for covert missions into Tibet. [127] On the morning of 4 March 1943, a B-17 sank the destroyer Asashio with a 500lb (230kg) bomb while she was picking up survivors from Arashio. 7375, 15859. The first two ex-USAAF B-17s, a B-17F (later modified to B-17G standard) and a B-17G were obtained by the Navy for various development programs. As the war intensified, Boeing used feedback from aircrews to improve each new variant with increased armament and armor. These modifications resulted in a 20% increase in aircraft weight. ", "Langley B-17s paved way for independent Air Force", "World War II General Electric Turbosupercharges", "Flying Fortress (B-17G): A Survey of the Hard-hitting American Heavy Weight. "Smithsonian Panel Backs Transfer of Famed B-17 Bomber.". [103] However, due to the slow 715mph velocity and characteristic ballistic drop of the fired rocket (despite the usual mounting of the launcher at about 15 upward orientation), and the small number of fighters fitted with the weapons, the Wfr. "Boeing's Battle Wagon: The B-17 Flying Fortress An Outline History". 60 Of the 291 attacking Fortresses, 60 were shot down over Germany, five crashed on approach to Britain, and 12 more were scrapped due to damage - a loss of 77 B-17s. Log in. The first Schweinfurt-Regensburg Raid occurred during >World War II (1939-1945). The 8th Air Force then targeted the ball-bearing factories in Schweinfurt, hoping to cripple the war effort there. [36], A 14th Y1B-17 (37-369), originally constructed for ground testing of the airframe's strength, was upgraded by Boeing with exhaust-driven General Electric turbo-superchargers, and designated Y1B-17A. Many historians have written about the famous Buffalo Soldiers of the all-Black 92nd Infantry Division, who fought with distinction during World War II. Subjects > Humanities > History. The Soviets restored 23 to flying condition and concentrated them in the 890th bomber regiment of the 45th Bomber Aviation Division,[153] but they never saw combat. [7] The USAAF bombers attacked by day, with British operations chiefly against industrial cities by night.
