PT-127 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 September 1942 in Motor Torpedo Boat Squadron 7.
On the night of 24-25 October 1944 Ensign Dudley J. Johnson had her in Lieutenant (junior grade) John A. Cady's section, near Camiguin. The boats were among 39 under Commander Selman S. Bowling. She did not make the first visual contact. She made the first radio report.
At 0010 on 25 October, with Lieutenant (junior grade) Ian D. Malcolm aboard and PT-130's own set dead, Johnson's boat sent the position, course, and speed of Vice Admiral Shoji Nishimura's force. The chain ran from PT-130 to PT-127 to the tender Wachapreague to Louisville. She was not hit.
She transferred to Squadron 12 on 15 February 1945 and was stripped and destroyed on 26 October 1945.
