The authors of a photo book about the planes and . 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." B-17 Flying Fortress - Top Facts About the WWII American Bomber [140], After the first Y1B-17s were delivered to the Army Air Corps 2nd Bombardment Group, they were used on flights to promote their long range and navigational capabilities. Tora! [116] A series of disputed discussions and decisions, followed by several confusing and false reports of air attacks, delayed the authorization of the sortie. 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. Yenne, Bill, "B-17 at War": p. 16; Zenith Press; 2006: B-17 Erection and Maintenance Manual 01-20EE-2. The bombers were assumed either lost by various means or scrapped late in the war for their vital war materials. [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. The XB-38 was an engine testbed for Allison V-1710 liquid-cooled engines, should the Wright engines normally used on the B-17 become unavailable. Lacking a true heavy bomber at the start of World War II, the RAF purchased 20 B-17Cs. German Me 262s Gun Down B-17s | Military.com The Allied victory against the Axis was a long journeyone that actually took much longer than the war itself. Though many were shot down, many more severely damaged aircraft were able to return their crews safely to base. The B-17 was a sturdily built aircraft. In July 1940, an order for 512 B-17s was issued,[43] but at the time of the attack on Pearl Harbor, fewer than 200 were in service with the army. After Dallas airshow crash, how many B-17s are still flying? Frisbee, John L. "Valor: Gauntlet of Fire". [91], The USAAF began building up its air forces in Europe using B-17Es soon after entering the war. ", "Why Use Colourful Camouflage in World War 2? His views were supported by Eighth Air Force statisticians, whose mission studies showed that the Flying Fortress's utility and survivability was much greater than those of the B-24 Liberator. [30] One suggestion adopted was the use of a preflight checklist to avoid accidents such as that which befell the Model 299. The B-17G was the final version of the Flying Fortress, incorporating all changes made to its predecessor, the B-17F,[57] and in total, 8,680 were built,[68] the last (by Lockheed) on 28 July 1945. As the war intensified, Boeing used feedback from aircrews to improve each new variant with increased armament and armor. [citation needed], Another early World War II Pacific engagement, on 10 December 1941, involved Colin Kelly, who reportedly crashed his B-17 into the Japanese battleship Haruna, which was later acknowledged as a near bomb miss on the heavy cruiser Ashigara. [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 Germans broke off to refuel having shot down 15 B-17s. The competition for the air corps contract was to be decided by a "fly-off" between Boeing's design, the Douglas DB-1, and the Martin Model 146 at Wilbur Wright Field in Dayton, Ohio. World War 2 . . [20] The YB-17 incorporated a number of significant changes from the Model 299, including more powerful Wright R-1820-39 Cyclone engines. [123] The allied fighter pilots claimed 15 Zeros destroyed, while the B-17 crews claimed five more. [134] To address this problem, the United States developed the bomb-group formation, which evolved into the staggered combat box formation in which all the B-17s could safely cover any others in their formation with their machine guns. [33] The mission was successful and widely publicized. This was operated by German-speaking radio operators who were to identify and jam German ground controllers' broadcasts to their nightfighters. She was featured in a USAAF documentary, Memphis Belle: A Story of a Flying Fortress. 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. [69] Many B-17Gs were converted for other missions such as cargo hauling, engine testing, and reconnaissance. However, the use of this rigid formation meant that individual aircraft could not engage in evasive maneuvers: they had to fly constantly in a straight line, which made them vulnerable to German flak. [citation needed] As a result, the B-17s' loss rate was up to 25% on some early missions. 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. Gr. The RAF entered World War II with no heavy bomber of its own in service; the biggest available were long-range medium bombers such as the Vickers Wellington, which could carry up to 4,500 pounds (2,000kg) of bombs. Operational History. See answer . Some SB-17s had their defensive guns removed, while others retained their guns to allow use close to combat areas. The Me 262, however, had moderate success against the B-17 late in the war. "Smithsonian Panel Backs Transfer of Famed B-17 Bomber.". The Ball turret itself has inspired works like Steven Spielberg's The Mission. [173], The B-17, a versatile aircraft, served in dozens of USAAF units in theaters of combat throughout World WarII, and in other roles for the RAF. ", "Question How many bomber flight crews completed their 25 missions to go home?". Before the advent of long-range fighter escorts, B-17s had only their .50 caliber M2 Browning machine guns to rely on for defense during the bombing runs over Europe. The current total of surviving B-17 bombers located in the United States stands at 40: Nine (9) B-17 planes are airworthy, such as "Texas Raiders", "Sentimental Journey" and "Aluminum Overcast". During a bombing mission on July 5, 1943, Warner shot down 7 German fighters, for which he was given the Distinguished Service Cross. London: Arakaki and Kuborn 1991, pp. [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. By the time the B-17s and escorting Curtiss P-40 Warhawk fighters were about to get airborne, they were destroyed by Japanese bombers of the 11th Air Fleet. 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. [103] Additionally, 122 bombers were damaged and needed repairs before their next flights. [129] Surviving aircraft were reassigned to the 54th Troop Carrier Wing's special airdrop section and were used to drop supplies to ground forces operating in close contact with the enemy. One of the two "E" Flying Fortresses was photographed late in the war by U. S. aerial recon. [154], During the Allied bomber offensive, U.S. and British bombers sometimes flew into Swiss airspace, either because they were damaged or, on rare occasions, accidentally bombing Swiss cities. Smith and LeSchack parachuted from the B-17 and searched the station for several days. However, the USAAF continued using the B-17 as a day bomber, despite misgivings by the RAF that attempts at daylight bombing would be ineffective. 'Black Thursday': The bleakest day for U.S. Army Air Forces in World War II The first raid on 17 August 1943 did not result in critical damage to the factories, with the 230 attacking B-17s being intercepted by an estimated 300 Luftwaffe fighters. [72], The first four drones were sent to Mimoyecques, the Siracourt V-1 bunker, Watten, and Wizernes on 4 August, causing little damage. The idea of a pilot's checklist spread to other crew members, other air corps aircraft types, and eventually throughout the aviation world. But help soon arrived when the North American P-51 Mustang began to reach the beleaguered Eighth Air Force in large enough numbers to make a difference. info@nationalww2museum.org However, B-17s were operating at heights too great for most A6M Zero fighters to reach. Although initially deemed repairable, 40-2049 (11th BG / 38th RS) received more than 200 bullet holes and never flew again. How many b17 bombers were lost in ww2? The adoption of the 21 cm Nebelwerfer-derived Werfer-Granate 21 (Wfr. Additional armament included an additional dorsal turret in the radio room, a remotely operated and fired Bendix-built "chin turret" directly below the bombardier's accommodation, and twin .50in (12.7mm) guns in each of the waist positions. The aircraft was powered by four Pratt & Whitney R-1690 Hornet radial engines, each producing 750 hp (600 kW) at 7,000 ft (2,100 m). A New Orleans native, James Linn first became involved with the institution then known as The National D-Day Museum in 2001 as an eighth-grade volunteer on weekends and during the summer. [72], The B-17 began operations in World WarII with the Royal Air Force (RAF) in 1941, and in the Southwest Pacific with the U.S. Army. Crashed Model 299. For other uses, see, "Flying Fortress" redirects here. [167], During the last year of World War II and shortly thereafter, the United States Navy (USN) acquired 48 ex-USAAF B-17s for patrol and air-sea rescue work. Frisbee, John L. "Valor: First of the Few". The aircraft went through several alterations in each of its design stages and variants. B-17 Flying Fortresses The B-17 Flying Fortress became a symbol of the power of the United States and its air force. 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. The only prototype XB-38 to fly crashed on its ninth flight, and the type was abandoned. [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. Depends on when they flew. [225][226], "B-17" redirects here. [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. In 1957 the surviving B-17s had been stripped of all weapons and painted black. Assembly Ships", "Polka Dot Warriors > Vintage Wings of Canada", "Excerpts from B-17 Pilot Training Manual (The Story of the B-17). [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. And by 27 April 1945, 2 days after the last heavy bombing mission in Europe, the rate of aircraft loss was so low that replacement aircraft were no longer arriving and the number of bombers per bomb group was reduced. In theory, in the words of British Prime Minister Stanley Baldwin,the bomber will always get through. The Americans believed the B-17, with the Norden bomb sight, could be that bomber. A Fortress IIA from No. These losses were a result of concentrated attacks by over 300 German fighters. [6] But it was primarily employed by the USAAF in the daylight strategic bombing campaign over Europe, complementing RAF Bomber Command's night-time area bombing of German industrial, military and civilian targets. It was a relatively fast, high-flying, long-range bomber with heavy defensive armament at the expense of bombload. Serial number 44-85784 is the last airworthy B-17 in the United Kingdom and is based at the Imperial War Museum Duxford. Fewer than 10 are airworthy . 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. The Eighth Air Force vs. The Luftwaffe - The National WWII Museum [10] The B-17's armament consisted of five .30 caliber (7.62mm) machine guns, with a payload up to 4,800lb (2,200kg) of bombs on two racks in the bomb bay behind the cockpit. Frisbee, John L. "Valor: Crisis in the Cockpit". During World War II approximately 40 B-17s were captured and refurbished by Germany after crash-landing or being forced down, with about a dozen put back into the air. The B-17 saw early action in the Pacific War, where it conducted raids against Japanese shipping and airfields. Study now. The B-17 was designed by the Boeing Aircraft Company in response to a 1934 Army Air Corps specification that called for a four-engined bomber at a time when two engines were the norm. The two "E"s were used to develop B-17 air combat counter-tactics and also used as enemy aircraft in pilot and crew training films. They could also pose as ground controllers themselves with the intention of steering nightfighters away from the bomber streams. ", "Chapter 18: Rouen-Sotteville, No. [citation needed], Two additional groups arrived in Britain at the same time, bringing with them the first B-17Fs, which served as the primary AAF heavy bomber fighting the Germans until September 1943. Gift of Peggy Wallace, 2010.308.044, Group of B-17 bombers over Europe with vapor trail flowing behind them, 1944-45. 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. They also desired, but did not require, a range of 2,000mi (3,200km) and a speed of 250mph (400km/h). The Allison V-1710 was allocated to fighter aircraft. 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. [99], Since the airfield bombings were not appreciably reducing German fighter strength, additional B-17 groups were formed, and Eaker ordered major missions deeper into Germany against important industrial targets. National Archives and Records Administration - ARC Identifier 2870 / Local Identifier 18-C-406-2 - AIR WAR IN EUROPE - War Department. B-17's Shot Down During Raid - YouTube The experience showed both the RAF and USAAF that the B-17C was not ready for combat, and that improved defenses, larger bomb loads and more accurate bombing methods were required. (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. [25] Army Chief of Staff Malin Craig cancelled the order for 65 YB-17s, and ordered 133 of the twin-engined Douglas B-18 Bolo, instead.[19][20]. A merica joined Britain's strategic air campaign designed to destroy Nazi Germany's industrial capacity soon after her entrance into World War Two. A sobering statistic: Out of 1,419 Loaches built, 842 were destroyed in Vietnam, most shot down and many others succumbing to crashes resulting from low-level flying. [110] The escort fighters reduced the loss rate to below 7%, with a total of 247 B-17s lost in 3,500 sorties while taking part in the Big Week raids. [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. List of surviving Boeing B-17 Flying Fortresses - Wikipedia The prototype B-17, with the Boeing factory designation of Model 299, was designed by a team of engineers led by E. Gifford Emery and Edward Curtis Wells, and was built at Boeing's own expense. Their first operation, against Wilhelmshaven on 8 July 1941 was unsuccessful. The B-17 Flying Fortress became symbolic of the United States of America's air power. Designed by Dr. Sanford Moss, engine exhaust gases turned the turbine's steel-alloy blades, forcing high-pressure ram air into the Wright Cyclone GR-1820-39 engine supercharger. Losses were relatively low - below the 5% threshold that was the. Many historians have written about the famous Buffalo Soldiers of the all-Black 92nd Infantry Division, who fought with distinction during World War II.

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. The Name [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. 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. Leonard "Smitty" Smith Humiston, co-pilot on First Lieutenant Robert H. Richards' B-17C, AAF S/N 40-2049, reported that he thought the U.S. Navy was giving the flight a 21-gun salute to celebrate the arrival of the bombers, after which he realized that Pearl Harbor was under attack. On landing, the aircraft overran the runway and ran into a ditch, where it was then strafed. [168], Thirty-two B-17Gs[169] were used by the Navy under the designation PB-1W, the suffix -W indicating an airborne early warning role. Its main use was in Europe, where its shorter range and smaller bombload relative to other aircraft did not hamper it as much as in the Pacific Theater. Linn joined The National WWII Museum staff in 2014 andservedas a Curator until 2020. Ramsey, Winston G. "The V-Weapons". [37] Scheduled to fly in 1937, it encountered problems with the turbochargers, and its first flight was delayed until 29 April 1938. [114], By 1941, the Far East Air Force (FEAF) based at Clark Field in the Philippines had 35 B-17s, with the War Department eventually planning to raise that to 165. While the US Fifteenth Air Force also had B-17s, the most famous group to fly them during the war was the US Eighth Air Force based out of England. As sufficient Consolidated Liberators finally became available, Coastal Command withdrew the Fortress from the Azores, transferring the type to the meteorological reconnaissance role. Memphis Belle (aircraft) - Wikipedia Tragically, the plane stalled and spun into the ground soon after takeoff, bursting into flames.

On 2 March 1943, six B-17s of the 64th Squadron flying at 10,000ft (3,000m) attacked a major Japanese troop convoy off New Guinea, using skip bombing to sink Kyokusei Maru, which carried 1,200 army troops, and damage two other transports, Teiyo Maru and Nojima. [143] This durability, together with the large operational numbers in the Eighth Air Force and the fame achieved by the Memphis Belle, made the B-17 a key bomber aircraft of the war. 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. The B-17 finally had a fighter which could escort them in and out of Germany, and began to overwhelm German defenses and industry. What was the life expectancy of a B-17 crewman flying over - Quora How effective was WWII bombers self defense anti-air armament? The B-17s attracted a number of Mitsubishi A6M Zero fighters, which were in turn attacked by the P-38 Lightning escorts. "[22][23], The crashed Model 299 could not finish the evaluation, disqualifying it from the competition.

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. Yes, for instance, M/SGT Michael Arooth shot down 17 enemy aircraft to reach triple "Ace" status. But because the bombers could not maneuver when attacked by fighters and needed to be flown straight and level during their final bomb run, individual aircraft struggled to fend off a direct attack. [62][63], The YB-40 was a heavily armed modification of the standard B-17 used before the North American P-51 Mustang, an effective long-range fighter, became available to act as escort. In January 1938, group commander Colonel Robert Olds flew a Y1B-17 from the U.S. east coast to the west coast, setting a transcontinental record of 13 hours 27 minutes. Who manufactured the Norden bombsight? - TimesMojo Originally, the B-17 was also chosen because of its heavy defensive armament, but this was later removed.
