The Puma HC1 first entered service with the Royal Air Force in 1971, and following an extensive upgrade to HC2 standard, are still operational today. The Pumas are used as battlefield helicopters within the Joint Helicopter Command and provide tactical troop and load movement by day or by night. The aircraft can carry up to 16 passengers or 12 fully-equipped troops, or up to two tonnes of freight carried either internally or as an under-slung load. The other major role is that of medical evacuation support, for which up to six stretchers can be fitted. 230 Squadron will be providing a Puma HC2 for static display at the Air Show, which will be parked in the Battlefield Support ground displays.
