of World War II in early 1942, it was also used in the Mediterranean Theater and in Western Europe. After entering service with the United States Army aviation units, the aircraft quickly received the reputation of a " widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach speeds, and when they slowed to speeds below those stipulated in the manual the aircraft would often stall and crash.Ethell 1995, p. 242. The B-26 became a safer aircraft once crews were re-trained, and after aerodynamics modifications (an increase of wingspan and wing angle-of-incidence to give better takeoff performance, and a larger vertical stabilizer and rudder).Ethell 1995, pp. 242–243. The Marauder ended World War II with the lowest loss rate of any U.S. Army Air Forces bomber.Ethell 1995, p. 243. A total of 5,288 were produced between February 1941 and March 1945; 522 of these were flown by the Royal Air Force and the South African Air Force. By the time the United States Air Force was created as an independent military service separate from the United States Army in 1947, all Martin B-26s had been retired from U.S. service. After the Marauder was retired the unrelated Douglas A-26 Invader then assumed the "B-26" designation which led to confusion between the two aircraft.

, to meet the requirement, the Martin Model 179. Martin's design was evaluated as superior to the other proposals and was awarded a contract for 201 aircraft, to be designated B-26.''Air International'' January 1988, p. 23. The B-26 went from paper concept to an operational bomber in approximately two years.Trent 2008, p. 647. Additional orders for a further 930 B-26s followed in September 1940, still prior to the first flight of the type.''Air International'' January 1988, p. 25. The B-26 was a shoulder-winged monoplane of all-metal construction, fitted with a tricycle landing gear. It had a streamlined, circular section fuselage housing the crew, consisting of a bombardier in the nose, armed with a machine gun, a pilot and co-pilot sitting side by side, with positions for the radio operator and navigator behind the pilots. A gunner manned a dorsal turret armed with two machine guns (the first powered dorsal turret to be fitted to a U.S. bomber), and an additional machine gun was fitted in the tail. Two bomb bays were fitted mid-fuselage, capable of carrying of bombs, although in practice such a bomb load reduced range too much, and the aft bomb bay was usually fitted with additional fuel tanks instead of bombs. The aircraft was powered by two Pratt & Whitney R-2800 Double Wasp radial engines in nacelles slung under the wing, driving four-bladed propellers. The engines were manufactured at the Ford Dearborn Engine plant in

Accidents

The B-26's relatively small wing area and resulting high wing loading required a high landing speed of indicated airspeed depending on load. At least two of the earliest B-26s suffered hard landings and damage to the main landing gear, engine mounts, propellers and fuselage. The type was grounded briefly in April 1941 to investigate the landing difficulties. Two causes were found: insufficient landing speed (producing a stall) and improper weight distribution. The latter was due to the lack of a dorsal turret; the Martin power turret was not yet ready. Some of the very earliest B-26s suffered collapses of the nose landing gear. It is said that they were caused by improper weight distribution, but that is not likely to have been the only reason. The incidents occurred during low-speed taxiing, takeoffs and landings, and occasionally the strut unlocked. Later the Martin electric dorsal turret was retrofitted to some of the first B-26s. Martin also began testing a taller vertical stabilizer and revised tail gunner's position in 1941. The Pratt & Whitney R-2800-5 engines were reliable, but the Curtiss electric pitch change mechanism in the propellers required impeccable maintenance, not always attainable in the field. Human error and some failures of the mechanism occasionally placed the propeller blades in flat pitch resulting in an overspeeding propeller, sometimes known as a "runaway prop". Due to its sound and the possibility that the propeller blades could disintegrate, this situation was particularly frightening for aircrews. More challenging was a loss of power in one engine during takeoff. These and other malfunctions, as well as human error, claimed a number of aircraft and the commanding officer of the

s were proving the merits of the bomber. For a time in 1942, pilots in training believed that the B-26 could not be flown on one engine. This was disproved by several experienced pilots, including Colonel Jimmy Doolittle, who flew demonstration flights at MacDill Army Air Field, which featured take offs and landings with only one engine. Also, seventeen Women Airforce Service Pilots were trained to demonstrate the B-26, in an attempt to "shame" male pilots into the air. In 1942, aviation pioneer and company founder

"), which was investigating defense contracting abuses. Senator Harry S Truman of Missouri, the committee chairman (and future Vice President and 33rd President of the United States in 1945-1952), asked Martin why the B-26 had problems. Martin responded that the wings were too short. Senator Truman curtly asked why the wings had not been changed. When Martin replied that the plans were too close to completion, and his company already had the contract, Truman's testy response was quick and to the point: In that case, the contract would be canceled. Martin corrected the wings. (By February 1943, the newest model aircraft, the B-26B-10, had an additional of wingspan, plus uprated engines, more armor and larger guns.)

Other colorful nicknames included "Martin Murderer", "Flying Coffin", "B-Dash-Crash", "Flying Prostitute" (so-named because it was so fast and had "no visible means of support," referring to its small wings) and "Baltimore Whore" (a reference to the city where Martin was based). According to an article in the April 2009 edition of ''AOPA Pilot'' on Kermit Weeks' "Fantasy of Flight", the Marauder had a tendency to "hunt" in yaw. This instability is similar to "

". This would make for a very uncomfortable ride, especially for the tail gunner. The B-26 is stated by the 9th Air Force to have had the lowest combat loss rate of any US aircraft used during the war. Nevertheless, it remained a challenging aircraft to fly and continued to be disliked by some of its pilots throughout its military career. In 1944, in answer to many pilots complaining to the press and their relatives back home, the USAAF and Martin took the unusual step during war of commissioning large articles to be placed in various popular publications to educate the public and defend the flying/accident record of the B-26 against "slanders". One of the longest of these articles was in the May 1944 issue of '' Popular Mechanics''."They Said It Was Too 'Hot' To Fly."
''Popular Mechanics'', May 1944.


Operational history

The B-26 Marauder was used mostly in Europe, but also saw action in the Mediterranean and the Pacific. In early combat, the aircraft took heavy losses, but was still one of the most successful medium-range bombers used by the US Army Air Forces. The B-26 was initially deployed on combat missions in the South West Pacific in early 1942, but most of the B-26s subsequently assigned to operational theaters were sent to England and the Mediterranean area. By the end of World War II, it had flown more than 110,000 sorties, dropped 150,000 tons (136,078 tonnes) of bombs and had been used in combat by British, Free French and South African forces in addition to US units. In 1945, when B-26 production was halted, 5,266 had been built.

which required an intermediate stop at Port Moresby, New Guinea, on 5 April 1942. A second group, the 38th, began receiving B-26s in November 1941 and began transitioning into them at Patterson Field, Ohio. There, the 38th continued the testing of the B-26, including its range and fuel efficiency. Immediately after the entry of the United States into World War II, plans were tentatively developed to send the 38th BG to the South West Pacific and to equip it with B-26Bs fitted with more auxiliary fuel tanks and provisions for carrying

. In 1943, it was decided that the B-26 would be phased out of operations in the South West Pacific Theater in favor of the North American B-25 Mitchell. Nevertheless, the 19th Bombardment Squadron of the 22nd BG continued to fly missions in the B-26. The B-26 flew its last combat mission in the theater on 9 January 1944. Two more squadrons of torpedo armed B-26s equipped the 28th Composite Group and were used for anti-shipping operations in the Aleutian Islands Campaign, but there are no records of any successful torpedo attack by a USAAF B-26.

Mediterranean Theater

Three Bombardment Groups were allocated to support the Allied invasion of French North Africa in November 1942. They were initially used to carry out low-level attacks against heavily defended targets, incurring heavy losses with poor results, before switching to medium level attacks. By the end of the North African Campaign, the three B-26 groups had flown 1,587 sorties, losing 80 aircraft. This was double the loss rate of the B-25, which also flew 70% more sorties with fewer aircraft.''Air International'' February 1988, pp. 76–77. Despite this, the B-26 continued in service with the Twelfth Air Force, supporting the Allied advance through Sicily, Italy and

Loss rates were far lower than in the early, low-level days, with the B-26 stated by the 9th Air Force as having the lowest loss rate in the European Theater of Operations at less than 0.5%.

. Although nominally the B-26B-10 was the first variant to receive the longer wing, it was actually installed on B-26Cs before the B-26B-10, both being in production simultaneously. A total of 123 B-26Cs were used by the RAF and SAAF as the Marauder Mk II. Approximate cost then: $138,551.27/aircraft (1,210 built) ** TB-26C—Originally designated AT-23B.

. The offensive and defensive abilities of the B-26E were tested in combat simulations against normal aircraft. Although the tests showed that gains were made with the new arrangement, they were insignificant. After a cost analysis, it was concluded that the benefit did not justify the effort needed to convert production lines for the new turret position. (One converted) * B-26F—Angle-of-incidence of wings increased by 3.5º; fixed .50 caliber machine gun in nose removed; tail turret and associated armor improved. The first B-26F was produced in February 1944. One hundred of these were B-26F-1-MAs. Starting with 42-96231, a revised oil cooler was added, along with wing bottom panels redesigned for easier removal. A total of 200 of the 300 aircraft were B-26F-2s and F-6s, all of which were used by the RAF and SAAF as the Marauder Mk III. The F-2 had the Bell M-6 power turret replaced by an M-6A with a flexible canvas cover over the guns. The T-1 bombsight was installed instead of the M-series sight. British bomb fusing and radio equipment were provided. (300 built) * B-26G—B-26F with standardized interior equipment. A total of 150 bombers were used by the RAF as the Marauder Mk III.
