When the United States Navy assumed full responsibility for the antisubmarine campaign in 1943, it became the 867th Bombardment Squadron and provided the cadre for a new Consolidated B-24 Liberator group.

[citation needed] Following the attack on Pearl Harbor the squadron began flying antisubmarine patrols off the Atlantic coast.

The emphasis on operations in the Gulf of Mexico was demonstrated when the squadron moved to Miami Army Air Field in June.

[8] The squadron remained at Barking Sands Army Air Field for additional training and modifications to its planes to meet theater standards until late September 1944, when it deployed to Angaur Airstrip in the Palau Islands.

[8] Although some unit aircrews flew combat missions with the 30th Bombardment Group from Saipan, the air echelon only began to arrive on Angaur on 24 October 1944, after the Seabees and Army engineers had prepared the airstrip for heavy bomber operations.

It also attacked the Philippines, hitting gun emplacements, bivouacs, and storage depots on Corregidor and Caballo Islands at the entrance to Manila Bay.

Early in 1945, the 867th struck ammunition and supply dumps in the Davao Gulf and Illana Bay areas of Mindanao and airfields on the island.

In December, the squadron returned to the United States, where it was inactivated at the Fort Lawton Port of Embarkation on 7 January 1946.

In May 2016 it was redesignated as the 867th Attack Squadron at Creech Air Force Base, Nevada and assigned to the 732d Operations Group of the 432d Wing.
