X-Plane 9+ Martin B-26B Marauder. The Martin B-26 Marauder was a World War II twin-engined medium bomber built by the Glenn L. Martin Company. First used in the Pacific Theater in early 1942, it was also used in the Mediterranean Theater and in Western Europe. In early combat the aircraft took heavy losses but was still one of the most successful medium-range bombers used by the U. S. Army Air Forces. By the end of World War II, it had flown more than 110, 000 sorties. In 1945, when B26 production was halted, 5266 had been built. By Larry Cole.
