Daito Jima. During the Okinawa campaign she took several enemy planes under fire as she guarded carriers. On 18 April in collaboration with destroyers , , , and and planes from aircraft carrier , Heermann sank , a carrier of the kaitens—human-guided torpedoes. She continued to support carrier operations off Okinawa until sailing to Leyte Gulf for replenishment and repairs in late June. On 1 July she helped to screen the fast carrier force that devoted the ensuing five weeks to almost continuous air strikes and bombardment. On 15 August 1945 Heermann was on radar picket station some southeast of Tokyo when, several hours after the announcement of the end of hostilities, a kamikaze emerged from a cloud bank and began to dive in Heermanns direction—only to be splashed by the destroyer's gunners in one of the final naval actions of World War II. In the following weeks Heermann operated in the screen of the fast carrier task force providing air cover and air-sea rescue service. The destroyer entered Tokyo Bay on 16 September 1945 and remained in the area to support the occupation forces until 7 October when she sailed for the United States. Heermann was decommissioned at San Diego on 12 June 1946. 1951–1957 Heermann remained in reserve at San Diego until re-commissioning on 12 September 1951. After training in local waters off California, she departed San Diego on 4 January 1952 for her new base, NS Newport, Rhode Island, where she arrived on 23 January. She spent 1952 training along the eastern coast from New England to the Virginia Capes, followed by ASW and fleet problems during winter months in the Caribbean. The destroyer returned to Newport for operations along the Northeastern seaboard. After a voyage to Plymouth, England, in June and July 1953, she participated in antisubmarine maneuvers between Newport and the Virginia Capes. Heermann departed on a world cruise 3 December 1953. First she sailed for Yokosuka, Japan, by way of the Panama Canal, San Diego, and the Hawaiian Islands. After a two-day replenishment in Yokosuka, she set course for Okinawa where she acted as part of the escort for 3d Marine Division amphibious warfare landings and conducted barrier patrol in support of the exercise. After more maneuvers took her to Korea, Iwo Jima, and the South Coast of Japan, she returned to Yokosuka which she cleared 22 May 1954 to resume her world cruise,
