History
Hubbard was named in honor of Commander Joseph C. Hubbard (1900-1942), who was killed in action, while serving aboard the heavy cruiser USS San Francisco (CA-38) during the Naval Battle of Guadalcanal on 13 November 1942. She was launched by the Charleston Navy Yard on 11 November 1943; sponsored by Mrs. Helen L. Hubbard, widow of Commander Hubbard; and commissioned on 6 March 1944, Lieutenant Commander L. C. Mabley in command.
Hubbard sailed on 26 December 1944 with other destroyer escorts to hunt down weather-reporting U-boats in the Atlantic. Equipped with the latest direction-finding gear, the ships scouted the suspected area until they came upon U-248 on 16 January 1945. Depth charge attacks sank the German marauder late that morning. The ships arrived in New York on 6 February and, after additional training in Casco Bay, sailed again to search for submarines 4 April from NS Argentia, Newfoundland. As part of "Operation Teardrop", she took part in the destruction of the last desperate U-boat group to sortie, with escort carriers Bogue (CVE-9), Core (CVE-13), and many sister ships. Frederick C. Davis (DE-136) was torpedoed and sunk suddenly on 24 April, and Hubbard joined in hunting the attacker. After many depth charge attacks, four by Hubbard alone, U-546 surfaced. The destroyer escorts' guns quickly sank the submarine.
