Flown exclusively by the US Marines, the PBJ was one of those rare examples of an air force type being procured by the navy due to its ability to do exactly the job that was required of it. Bought as a land-based patrol bomber for operations in the Atlantic and Pacific, the PBJ (Patrol, Bomber, North American) was kitted out to hunt down submarines as well as surface vessels. Identical to its air force counterpart, except for its ability to lay mines, deploy depth charges and launch torpedoes, some 706 PBJs were delivered to the Marine Corps from 1943-45. This book outlines the aircraft's history and technology, and takes a closer look at the men who flew it.
