NZ3801 joined No.3 Squadron in June 1966 and was upgraded to UH-1H in the mid 70’s. Amongst the many duties, NZ3801 saw overseas service in support of UN-operations in East Timor early in the new millennium, marked ‘UNO-075’ and later 'UNO-077'.
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.
