Completed in 1954, the Daring-class destroyer HMS Diana (D126) saw action during the 1956 Suez Crisis. On 31 October, she was involved in the last sinking of a warship purely by gunfire to date, when she and the cruiser Newfoundland sank the Egyptian frigate Domiat. That same year, she was ordered to steam through the fallout zones from two nuclear tests to test the effects on the ship and crew. She served in the Royal Navy until 1969, when she was sold to Peru. Renamed BAP Palacios (DM-73), she was substantially rebuilt, replacing the foremast, and installing new radar, along with Exocet missiles, new guns, and a helicopter pad. Palacios remained active until she was decommissioned in 1993.
