The Iroquois is one of the world’s most iconic helicopters, famous for its extensive role in the Vietnam War and distinctive ‘whock-whock’ sound.

The Iroquois first entered RNZAF service in 1966, with five aircraft operating with No. 3 (Battlefield Support) Squadron at Hobsonville. Nine more were delivered in 1970. Two aircraft were based for many years at the No. 3 Squadron Detachment at Wigram for Army support and search and rescue duties, and four served in Singapore until 1989. RNZAF Iroquois were used in the Antarctic, in the South Pacific (especially in Bougainville and Solomon Islands), and in Timor Leste, performing a wide range of duties, before finally being retired from service in 2015.
