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


The 25th Bombardment Group was part of the American garrison in the Caribbean from 1940 until 1944 when it returned to the US before being disbanded.

The group moved to Puerto Rico in November 1940, after the Air Corps was given permission to built an airfield on the island.

In 1941 the 25th Bombardment Group formed part of a small composite wing based on Puerto Rico. In April 1941 the entire wing could only boast three A-17s and twenty-one B-18As, despite officially containing two full groups and one reconnaissance squadron.

After the American entry into the Second World War the 25th was used to fly a mix of antisubmarine patrols, convoy escorts and general defensive sorties. It remained on Puerto Rico until November 1942, and moved twice in the Caribbean before returning to the US in April 1944. The group was officially converted to the B-17, but disbanded on 20 June 1944.
