PBJ-1 with APS-3 radar
The U.S. Navy acquired a total of 236 B-25H Mitchell bombers, which were redesignated as PBJ-1Hs for naval service. These aircraft were primarily operated by the U.S. Marine Corps and were adapted for various roles in the Pacific Theater during World War II. Here’s an overview of the modifications and roles of the PBJ-1H:
Modifications and Features:
- Search Radar Installations:
- Wingtip Radar: Some PBJ-1Hs were equipped with a search radar mounted on the right wing tip. This radar was used for maritime patrols, enabling the aircraft to detect enemy ships and submarines at greater distances, even in poor visibility conditions.
- Nose Radome: Other PBJ-1Hs had a radome installed on the nose of the aircraft, housing the radar equipment. This configuration was often used for anti-shipping missions and bombing runs, allowing the crew to identify and target enemy vessels more effectively.
- No Radome: A portion of the PBJ-1Hs were operated without any radome at all. These aircraft were likely used in roles where radar was less critical, such as close air support or missions where visual targeting was sufficient.
Operational Role:
Marine Corps Operations:
- The PBJ-1H served extensively with the Marine Corps, which used these aircraft in a variety of roles, including anti-shipping, close air support, and patrol missions. The Marine Corps adapted the PBJ-1H for the challenging conditions of the Pacific Theater, where its heavy armament and versatility made it a valuable asset against Japanese forces.
Multi-role Capabilities:
- The PBJ-1H’s powerful nose armament, which included four .50-caliber machine guns and a 75mm cannon, made it ideal for strafer missions and low-level attacks. The addition of radar allowed for night operations and improved the aircraft’s effectiveness in poor weather or against camouflaged targets.
