USS PT-194 was a motor torpedo boat of the United States Navy, the hull numbered PT-194. She was a PT, one of the small, fast torpedo craft the Navy used for work in narrow waters.
The night set down for her is 24–25 October 1944, in Surigao Strait. She was one of the motor torpedo boats on patrol there through that night.
Thirty-nine boats made up the patrol. PT-194 was counted among them as the strait was watched from the evening of 24 October into the morning of the 25th.
That patrol is how she enters the Battle of Surigao Strait, dated 25 October 1944. The battle line places her with the motor torpedo boats on duty in the strait, in the patrol rather than in any separate action of her own.
The note on her hull is the same night's duty. PT-194 is carried as one of the motor torpedo boats that patrolled Surigao Strait on 24–25 October 1944, among the thirty-nine boats out when the battle was fought.
