PT-151 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 4 November 1942 in Motor Torpedo Boat Squadron 9 and transferred to Squadron 12 on 10 May 1943.
On the night of 24-25 October 1944 Ensign John M. Ladd had her in Lieutenant (junior grade) Dwight H. Owen's section, with PT-146 and PT-190, northeast of Limasawa Island. The boats were among 39 under Commander Selman S. Bowling.
At about two miles she fired one torpedo. It ran straight and missed. She zigzagged off behind smoke under heavy fire. Shell fragments did minor damage. With PT-146 she put 40 mm hits into the illuminating destroyer's superstructure and knocked the searchlight out. The destroyer is not identified. She was not sunk.
She was stripped and destroyed on 26 October 1945.
