History - Books - Aircraft - Time Line - Commanders - Main Bases - Component Units - Assigned To


The 378th Bombardment Group was a short-lived anti-submarine warfare unit that served in the US during 1942.

The group was activated on 18 October 1942 and inactivated two months later, on 14 December. It was given three squadrons, and for those two months carried out anti-submarine patrols off the US east coast.

The group was inactivated because of a change in the structure of the anti-submarine forces. A number of normal sized groups were disbanded and their squadrons formed into larger anti-submarine wings, in this case the 26th Antisubmarine Wing.
