PT-146 was an 80-foot Elco from the Elco Works at Bayonne: about 56 tons, three Packard gasoline engines, roughly 40 knots, and a crew of about 14 to 17. She was placed in service on 20 October 1942. She had passed through Squadrons 8 and 2 before returning to the Southwest Pacific.
On the night of 24-25 October 1944 Ensign Buford M. Grosscup had her in Lieutenant (junior grade) Dwight H. Owen's section, northeast of Limasawa Island, with PT-151 and PT-190. The boats were among 39 under Commander Selman S. Bowling.
She got off one torpedo, which ran erratic. With PT-190 she raked the illuminating destroyer with 40 mm fire until the light went out. The destroyer is not identified. She was not seriously damaged. The three boats fought with cannons and torpedoes until they were driven off.
She was stripped and destroyed on 26 October 1945.
