She went on to sink two Japanese sailing vessels, three Japanese coasters, a barge and a tug. Another coaster was forced ashore on Panjang Island. Spark was attacked by an enemy escort which dropped sixteen depth charges, but managed to escape damage. She returned to the UK in October 1945.

She was sold on October 28, 1949. Spark was broken up at Faslane in October 1950.
