The fourth HMS Spragge (K572) and third ship of the name to enter service was a British Captain-class frigate of the Royal Navy in commission during World War II.

The ship was laid down as the unnamed U.S. Navy destroyer escort DE-563 by Bethlehem-Hingham Shipyard, Inc., in Hingham, Massachusetts, on 15 September 1943 and launched on 16 October 1943.

In May, the group was assigned to escort Allied landing forces during Operation Neptune, the initial assault of the upcoming invasion of Normandy scheduled for June 1944, as well as to defend convoys bringing supplies and reinforcements to the beachhead thereafter.

She continued in these duties until February 1945, when she collided with a landing craft during a voyage from Walcheren to the United Kingdom, injuring one rating and holing her bow, requiring her to undergo several weeks of repairs.

Between June and August 1945 – when the armistice with Japan brought World War II to a close – she underwent conversion for her new role, which involved removal of all of her armament and modifications to her electrical system, at Portsmouth Dockyard.

Based there, she carried out duties for the British Pacific Fleet – for a frigate typically consisting of patrolling the sea lanes in East Asia and transporting personnel and supplies to and between military garrisons in French Indochina, China, and Japan – until January 1946, when the Royal Navy selected her for return to the U.S.
