This is the fifth book in the series of photographs of British combat aircraft of the 1970s and 1980s and covers the RAF helicopters in service during those two decades and their part in the latter stages of the Cold War.The Westland Whirlwind was used in the air-sea rescue (ASR) role before being replaced by the Westland Sea King, both aircraft being prominent around the British coastline with their bright yellow colouring.The Westland Wessex was used by the RAF in a variety of roles including search and rescue.The A rospatiale Puma was introduced to service with the RAF in 1968 and is still being flown today while the Boeing Chinook came into service in 1981, just in time to take part in the Falklands War, and is still in service today.Containing 180 photographs, this book is a pictorial compendium of these iconic machines.
