Convair XB-46 45-59582 LateThese are 1 72 scale decals for Convair XB 46 45 59582, depicted in its later configuration with United States Air Force (USAF) markings following the establishment of the independent Air Force in September 1947. The XB 46 was Convair's elegant entry in the postwar jet medium bomber competition, featuring a slender fuselage, straight wings with four Allison J35 turbojet engines in paired underwing nacelles, and a beautifully clean aerodynamic design.
