Naval aviation operates a fleet of eight Kaman SH-2G(I) Seasprite Helicopters. They are flown by Royal New Zealand Navy aircrew and maintained by Royal New Zealand Air Force No. 6 Squadron personnel.

The helicopters are deployed to Royal New Zealand Navy ships TE KAHA, TE MANA, CANTERBURY, OTAGO and WELLINGTON. When onboard TE KAHA and TE MANA the aircraft fulfil a combat and surveillance role as well as providing transport and vertical replenishment capabilities. When deployed onboard CANTERBURY, OTAGO and WELLINGTON the aircraft are primarily tasked to provide surveillance, reconnaissance, transport and vertical replenishment capabilities.

The Seasprite can be armed with a combination of:

  • homing torpedoes
