In the 1970s and ’80s, helicopters provided immeasurable support to both Royal Navy and the Army. The Westland Lynx flew with both branches in the anti-submarine (AS) and anti-tank (AT) role, as well as being used for transportation and battlefield support. The Westland Sea King served with the Royal Navy in the AS, airborne early warning, air-sea rescue (ASR), support and commando support roles. The diminutive Westland Wasp (Navy) was used in the AS role while the Scout (Army) was used in the transportation and AT roles. The Westland Wessex was used by the Royal Navy in a variety of roles including AS, general utility, commando support and ASR. The venerable Westland Whirlwind was also used in the ASR role. With over 180 black and white and colour photographs, this book, the sixth in a series on British combat aircraft of the 1970s and ’80s, showcases the major and minor helicopter types of the Royal Navy and Army and their part in the latter stages of the Cold War.
