The squadron also took over the responsibility for the Westland Wessex HAS1 helicopters operating from s. In 1969, the HAS1 was replaced by the Wessex HAS3. In December 1964, 829 NAS handed over the task of Wasp conversion to 706 Naval Air Squadron, and was relocated to RNAS Portland, Dorset. Until the Wasp was retired in 1988, the squadron remained responsible for all Wasp-equipped Ship's Flights. This led to several Wasps from the squadron, re-painted as a fictional HMS Hero Flight, being used in the popular 1970s BBC television drama series Warship.
