context_page_description: The North American B-25 Mitchell is a medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included a few limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber.

  One PBJ-1H was modified with carrier takeoff and landing equipment and successfully tested on the USS Shangri-La, but the Navy did not continue development.
  PBJ-1J
  U.S. Navy designation for the  B-25J (Blocks −1 through −35), it had improvements in radio and other equipment. Beside the standard armament package, the Marines often fitted it with 5-inch underwing rockets and search radar for the antishipping/antisubmarine role.
