The 35th Bombardment Squadron is an inactive United States Air Force unit. It was activated in January 1940 as the United States built up its armed forces prior to World War II. In the fall of 1941, it deployed to the Caribbean and, following the attack on Pearl Harbor engaged in antisubmarine patrols. Following the transfer of the land based antisubmarine mission to the Navy, and with the lessening of threats to the Panama Canal, the squadron returned to the United States, where it was disbanded in June 1944.
