A particular B-25H Mitchell underwent modifications by the Armament Laboratory of the Air Technical Service Command at Wright Field, Ohio. In this experimental variant, the aircraft’s standard 75-mm cannon was replaced with two experimental weapons known as rocket guns. Additionally, a single rocket gun was mounted under the forward fuselage.
Key Features:
Rocket Guns: These were distinct from the typical 4.5-inch triple rocket tubes that were commonly used on various U.S. aircraft during the period. The rocket guns were an innovative attempt to enhance the B-25H’s firepower, exploring new ways to integrate rocket-based weaponry into aerial combat.
Testing and Outcome: Despite the innovative approach, the rocket gun tests ultimately did not result in their adoption for operational use. The tests provided valuable data but were not seen as sufficiently effective to warrant widespread implementation on the B-25H or other aircraft.
