[3] As antisubmarine warfare assets were realigned to meet the growing threat in the North Atlantic, the 13th Group moved to Westover Field, Massachusetts.

At March, it converted to the Consolidated B-24 Liberator and replaced the 30th Group's 21st Bombardment Squadron, which had deployed to Alaska to participate in the Aleutian Campaign in 1942.

[1] The squadron moved forward to Saipan in the last week of July 1944, where the rest of the group joined it at Kobler Field in early August.

Its final bombing mission was at Iwo Jima on 19 February 1945,[citation needed] the same day three Marine divisions invaded the island.
