The 304th Bombardment Group was formed as a standard bombardment unit, but briefly served as an antisubmarine warfare unit in November and December 1942 before being inactivated at the end of December.

The group was activated on 15 July 1942, and was allocated four Bombardment Squadrons. The new group was based on the US West Coast, where it began to train as a bomber unit. After a few months of this it was decided to convert it into an anti-submarine unit. During November three of its squadrons were redesignated as antisubmarine squadrons (1st, 18th and 19th). The 19th began operations on around 1 November, the 1st on 10 November and the 421st Bombardment Squadron began at around the same time. The 18th Antisubmarine Squadron was used as an operational training unit.

The group had a short life span. The USAAF decided to organise its anti-submarine squadrons directly into wings, but the group began to shrink before the new wings became operational. The 1st Squadron was attacked to VIII Bomber Command when it began operations while the 421st came under the the control of Newfoundland Base Command on 6 November. Finally on 30 December 1942 the remaining two squadrons were transferred to the 25th Antisubmarine Wing, and the 304th Bombardment Group was inactivated.
