Vindex operated escorting convoys and doing anti-submarine work in the Atlantic and Arctic theatres. Her Swordfish aircraft were involved in the sinking of four U-boats during her service. She survived the war, and immediately afterwards served in the Far East transporting men and material to and from Japan. In 1947 she was decommissioned and sold to Port Line for commercial use, who operated the ship as the Port Vindex. In 1971 she was scrapped in Taiwan.
