Dace was a Gato-class submarine, SS-247. Electric Boat at Groton launched her on 25 April 1943, and the Navy commissioned her on 23 July 1943.
On the morning of 23 October 1944 she was in Palawan Passage with Darter, on the route Kurita's force was taking toward Leyte. Darter sank Atago and torpedoed Takao. Dace sank Maya. The heavy cruiser did not reach the Sibuyan Sea the next day.
That night Darter grounded on Bombay Shoal while she was closing the damaged Takao. Dace took off Darter's crew before dawn. No one from Darter was lost. Darter's demolition charges failed. Dace's torpedoes exploded on the shoal, and she put 21 four-inch hits into the hull. Dace was not sunk.
Dace survived the war.
