Manned by a Coast Guard crew, Huron conducted shakedown training off Bermuda during October and November.

While bringing together merchant ships which had become separated during the night, Huron was rammed by SS James Fenimore Cooper shortly after midnight on 8 December.

Though the engine room flooded rapidly, the ship's damage control work was timely and skillful, keeping her afloat.

After temporary repairs, Huron was towed through rough weather by Choctaw (AT-70), arriving at Bermuda on 15 December 1944.

Huron arrived at Key West, Florida, on 22 February 1945 for training operations at the Fleet Sonar School.
