One of two Bell 47’s on display at the Air Force Museum is NZ3705. The Sioux was the first helicopter to enter RNZAF service, with the first batch joining newly-formed No.3 (Battlefield Support) Squadron at Hobsonville in December 1965 and January 1966.
The last remaining Sioux helicopters left RNZAF-service in 2012. NZ3706 was initially retained for the RNZAF Historic Aircraft Flight at RNZAF Base Ohakea, but eventually came to the Air Force Museum of New Zealand, Wigram, in November 2021.
