[2] On 23 June 1948, Agincourt collided with the naval Motor Fishing Vessel MFV 1161, breaking off a 3 ft (0.9 m) length of deck plating from the destroyer.

A 12 feet (3.7 m) length of planking was torn off from Agincourt's port side, while Cadiz's starboard anchor was damaged.

In 1962, Agincourt returned to active duty and saw service in the Home and Mediterranean Fleets with a variety of squadrons.

[5] On 16 November 1962 Agincourt took part in the search for a helicopter from the aircraft carrier Hermes that had ditched off St David's Head in South west Wales (and in particular, the politician Lord Windlesham who was missing after the crash), and on the next day, was refuelling at Milford Haven when she was ordered to go to the aid of the replenishment tanker RFA Green Ranger, which was in difficulty while being towed in heavy seas off Hartland Point on the coast of Devon.

By the time Agincourt reached Hartland Point, Green Ranger's towline had parted, and the tanker had run aground.
