PBJ (B-25) Mitchell

The B-25 Mitchell was an incredibly versatile aircraft for the Allies during WWII. It proved its effectiveness by being utilized in every single theater of the war, after being introduced in 1942. Continued modifications assured its usefulness throughout the war and beyond.

It also showed how effective it was by the high rate of manufacturing during the war. So much so that the Army Air Corp looked to pass some off to other military branches. The Marines were happy to take them on, and these B-25s were designated PBJ. The “PB” stands for Patrol Bomber, and the “J” is an alpha-code that notes the manufacturer of B-25s - North American Aviation. The bomber visiting Tucson is painted in the colors of a Marine Corps PBJ-1J, named “Semper Fi” with Globe and Anchor painted on the starboard nose.
