The USS Aaron Ward (DD-132) was a Wickes-class destroyer constructed by Bath Iron Works in Bath, Maine, with her keel laid on August 1, 1918. She was launched on April 10, 1919, and commissioned on April 21, 1919, under the command of Lieutenant Commander Raymond A. Spruance. Her initial dimensions and armament reflected typical Wickes-class specifications, designed for versatility and speed during the post-World War I period. Upon commissioning, she joined the Atlantic Fleet's Destroyer Division 13, participating in her first notable duty in May 1919 as a picket for the transatlantic flight of three Curtiss NC flying boats, including the historic NC-4. Later that year, she was transferred to the Pacific Fleet, where she engaged in salvage operations in Angeles Bay, Baja California, recovering a downed Army aircraft and its crew. Her service also included rescue missions near the Panama Canal Zone, notably searching for the crashed NC-6 flying boat and rescuing survivors from the destroyer Woolsey after a collision. In 1920, her hull classification was updated to DD-132. After nearly three years of active duty, she was decommissioned on June 17, 1922, and placed in the Reserve Fleet at San Diego. She remained inactive until her recommissioning on May 24, 1930, serving intermittently with the Rotating Reserve until full activity resumed in December 1934. She was again decommissioned on April 1, 1937, but was recommissioned on September 30, 1939, in response to the rising global tensions. During World War II, USS Aaron Ward served as flagship of Destroyer Division 65 in the Pacific and later conducted neutrality patrols in the Gulf of Mexico and West Indies. On September 9, 1940, she was decommissioned at Halifax, Nova Scotia, and transferred to the Royal Navy under the destroyers-for-bases agreement, renamed HMS Castleton. She was modified for convoy escort duties, including the removal of some armament and the addition of anti-submarine weaponry such as depth charges and a Hedgehog mortar. HMS Castleton served throughout the Atlantic campaign, participating in convoy escort missions and hunting U-boats, notably detaining survivors of U-464 in 1942. Relegated to an air target ship in October 1944, she was paid off in March 1945 and sold for scrap in January 1948. The USS Aaron Ward's service exemplifies the versatility and enduring utility of Wickes-class destroyers through both World Wars and in allied cooperation efforts.
