SH-2G(I) Seasprite Helicopter

The Defence Force has 8 SH-2G(I) Seasprite maritime helicopters, operated by No. 6 Squadron.

They are flown by Royal New Zealand Navy aircrew and maintained by Royal New Zealand Air Force maintainers.

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 multiplying the capabilities of our naval fleet and fulfil a range of roles.

They can embark on Royal New Zealand Navy Ships HMNZS TE KAHA, TE MANA, CANTERBURY, WELLINGTON and OTAGO.

Seasprites are equipped with Penguin anti-ship missiles, torpedoes and the Mag 58 General Purpose Machine Gun.

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

  • Anti-surface warfare
  • Underwater warfare
  • Maritime patrols and surveillance
  • Search and rescue
  • Force protection
  • Utility operations (winching and load lifting)
  • Training of pilots, observers and helicopter loadmasters
