Lieutenant Haines remained at his station to assist in controlling the damage until overcome by asphyxiating gas generated by the explosion.

Departing Naples on 13 August, she escorted troop transports to the assault area, and later acted as a screening ship for the gunfire support group offshore.

She arrived at New York on 11 December and immediately entered the Brooklyn Navy Yard for conversion into a high speed transport.

She then served for several months at Norfolk and in Chesapeake Bay as a training ship for fast transport and destroyer escort crews.

Receiving orders to return to combat duty, Haines sailed from Norfolk for the Panama Canal on 8 August 1945.

She received word of the war's end while at Cristóbal, Canal Zone and proceeded to San Diego, California, where she continued to Pearl Harbor in early September.

For the next two months, the ship stopped at various Japanese ports while technicians and analysts from the strategic bombing survey team gathered data on the effectiveness of the aerial bombardments.
