HMS Danae was a Leander-class frigate of the Royal Navy, launched on 31 October 1965 and commissioned on 10 October 1967. Constructed at Devonport Dockyard, the vessel measured 372 feet (113.4 meters) in length overall, with a waterline length of 360 feet (109.7 meters). It had a beam of 41 feet (12.5 meters) and a maximum draught of 18 feet (5.5 meters). The ship's displacement was 2,380 long tons (2,420 tonnes) standard, increasing to 2,860 long tons (2,910 tonnes) at full load. Powered by Y-136 machinery built by J. Samuel White, Danae featured two oil-fired Babcock & Wilcox boilers feeding steam at 550 psi and 850°F to twin double reduction geared steam turbines rated at 30,000 shaft horsepower, enabling her to reach a top speed of 28 knots. Her armament initially included a twin 4.5-inch Mark 6 gun mount forward, a quadruple Sea Cat surface-to-air missile launcher on the hangar roof, two Oerlikon 20 mm cannon, and a Limbo anti-submarine mortar aft. She also had a helicopter deck and hangar to operate a Westland Wasp helicopter for extended anti-submarine and surface operations. Danae's radar suite comprised a Type 965 long-range air search radar, Type 993 short-range radar, and Type 974 navigation radar, complemented by an MRS3 fire control system and a GWS22 director for Sea Cat missiles. Her sonar equipment included Type 177 or 184 medium-range search sonar, Type 162 bottom search, and Type 170 attack sonar, with a well for Type 199 VDS sonar, which was never fitted. Throughout her service, Danae participated in various operational duties, including Gibraltar guardship duties, royal escort missions, Beira Patrols, and deployments to the Far East and North Atlantic. She served as a NATO flagship and was featured in the BBC TV series "Warship" in the 1970s. In 1977, she participated in HM Queen Elizabeth II’s Silver Jubilee Fleet Review. A significant modernization occurred between 1977 and 1980, replacing her original armament with Exocet anti-ship missiles, enlarging the flight deck, and upgrading sensors and anti-aircraft systems. In the early 1980s, Danae continued active deployments, including involvement in the South Atlantic post-Falklands War. She was decommissioned in 1991 and transferred to the Ecuadorian Navy, renamed BAE Morán Valverde, where she operated until her decommissioning in 2008 and subsequent scrapping in 2010.
