These walk-around photos were taken at the RAF Museum London in Hendon in 2019. They show a Westland Sea King HAR.3, serial XZ585 — the very first RAF Sea King to fly, and one of the most historically significant helicopters in the museum's collection. Originally designed by Sikorsky as an anti-submarine warfare helicopter, the Sea King was adapted by Westland for RAF search and rescue duties as the HAR.3, powered by two Rolls-Royce Gnome turboshaft engines and equipped with advanced navigation and search systems for all-weather operations. For nearly four decades its distinctive yellow livery was a familiar and reassuring sight along Britain's coastlines and mountains, rescuing both military personnel and civilians from some of the most inhospitable environments in the UK. XZ585 made its maiden flight on 6 September 1977 and was the first of its type in RAF service, initially retained by Westland for development work before joining No. 202 Squadron. Over its long career it served with multiple SAR flights around the UK, participating in countless rescues at sea and off mountain and cliff faces. In 2011 it was flown by HRH Prince William during his service as a search and rescue pilot at RAF Valley. After retirement in 2015, when the RAF's SAR role was transferred to civilian contractor Bristow Helicopters, XZ585 was donated to the RAF Museum and has been on display at Hendon since 2018.
