The Seasprite helicopter is operated by a three-person crew: a pilot, an observer who specialises in warfare and mission command, and a helicopter loadmaster who directs utility operations.

Delivered in 2015 to replace the previous SH-2G(NZ) model, these helicopters have an important role in enhancing the capabilities of our naval fleet and fulfil a range of roles.

They can embark in HMNZ Ships Te Kaha, Te Mana, Aotearoa, Canterbury, Wellington and Otago.

The SH-2G(I) can be equipped with Penguin anti-ship missiles, Mk 46 torpedoes and the Mag 58 General Purpose Machine Gun. 

The SH-2G(I) is primarily used for:

  • Anti-surface warfare
  • Underwater warfare
  • Maritime patrols and surveillance

The SH-2G(I) is also used for:

  • Search and rescue
  • Utility operations (winching and load lifting)
  • Domestic tasks for Government agencies such as the Department of Conservation and Ministry of Primary Industries
  • Training of pilots, observers and helicopter loadmasters
  • Training of ship’s Flight Deck Teams
