The Westland Wasp is a British-built helicopter that was used primarily by the Royal Navy, Army Air Corps and RAF. Nicknamed “the flying dustbin” due to its shape, it is best known for its role in the 1982 Falklands War. The Wasp has seen action across four decades of military service with many countries around the world. It’s sturdy design means that it can take off from rough ground or water without needing an airstrip or helipad. This versatility made it one of Britain’s most popular helicopters during the 1970s and 80s, when there were concerns about terrorist attacks on British soil.
