I am pretty sure the NH-90's are too heavy for the OPV's flight deck for a start let a lone how large all round they are... the NH-90's can only operate from HMNZS Canterbury, Manawanui and Aotearoa. (and to be fair I don't believe they have tested HMNZS Manawanui yet (but could be wrong there)

The changes to the SH-2G(I) from the RAN configuration was purposefully kept as minimal possible, RAST was replaced by Decklock being the main one. Almost everything else was kept the same, including the ASuW capability. The NH90 can't replace the Seasprite, it wont fit on most of our surface fleet, and has no ASuW or ASW capability, which are the two primary roles of the Seasprite. Wasn’t the troublesome fully automated ITAS flight control system also deleted, or disabled? That was the primary reason the RAN walked away from the aircraft. It was never reliable enough to allow the aircraft to be used against an adversary with state of the art AAW capability. No helicopter can be used against an "adversary with state of the art AAW capability", Ukraine is the best example of that. The ITAS was never reliable enough (for the RAN) period. Plus the cancellation of the OPV's meant the Sea Sprite didn't really have a small ship to play with. |

Back in the mid 1990s though, most ships carried RIM-7 or equivalent, which are pretty short ranged by today’s standards. Even the USN used AGM-119 on Seahawks. Up against a ship with ESSM or equivalent, it is a different story. No doubt those changing realities helped the RAN make up its mind whether to persevere with the Sea Sprite. |

Up against a ship with ESSM or equivalent, it is a different story. No doubt those changing realities helped the RAN make up its mind whether to persevere with the Sea Sprite. Sure, against ESSM or similar that is basically true. That said there were plenty of Russian vessels with longer range SAM's. Whether they were ever a realistic threat to the RAN is another matter. The inability of the ITAS to meet the RAN's reliability requirements for a single pilot (2 crew) helicopter was by far the main factor. Add in the OPV cancellation and some institutional dislike but the ITAS / single pilot was the biggie. The Missile was the one part of the programme that appeared to work as advertised. There was some thought of integrating it on the S-70B2. Once the OPV went there was really no point in Seasprite as the ANZAC could operate the S-70B2. Integrating Penguin on S-70B2 (if you still wanted the standoff range) and buying more (or the USN variant) would probably have been better |

Here you go Dave and Shorty (tongue only slightly in cheek) ITAS = Integrated Tactical Avionics System AAW = Air to Air warfare SAM = Surface to Air Missile OPV = offshore Patrol vessel (Sometimes called OPC offshore patrol combatant) ANZAC = in this case it refers to the class of ships. Surely I don't need to explain it's original meaning  RAN = Royal Australian Navy ESSM = Evolved SeaSparrow Missile USN = United States Navy AGM = Air to ground Missile HMNZS = (now) His Majesty's New Zealand Ship ASuW = Anti Surface Warfare ASW = Anti Submarine warfare RAST = Recovery Assist, Secure and Traverse MOTS= Military of the shelf FLIR = Forward Looking Infrared NVG = Night Vision Googles USD =United States Dollars CONOPS = Concept of Operations RNZAF = Royal New Zealand Air Force If I've missed any sing out |

Of course you could add:

You get the general idea.

And this from Scramble Link: www.scramble.nl/military-news/will-new-zealand-continue-using-the-nh90 Photo: NHIndustriesWill New Zealand continue using the NH90? Until now the NHIndustries NH90 has not developed into the success story it was supposed to have been. A number of its military users have obviously lost their faith in the European helicopter design. On 10 December 2021 Scramble reported on the Australian decision to withdraw their MRH90 Taipans ten years earlier than expected. The type entered the Australian Army service in 2008 and, despite its speed, range, and troop capacity performance advantages over the Black Hawk it replaced, has been plagued with poor availability and a number of fleet-wide groundings in Australian service. According to Australian sources these problems were caused by a lack of spares and configuration management issues. More recently, on 22 March 2023 Australian Army Aviation Corps (AAAC) NHIndustries NH90 MRH Taipan A40-025 made a forced landing in Jervis Bay off New South Wales during a night time antiterrorist exercise. This accident has speeded up the replacement of the NH90 by US manufactured UH-60M Blackhawk helicopters. It was around a year ago, on 10 June 2022, that Scramble posted on the situation in Norway, a country which instantly stopped operating the NH90 at that time. Since then Norway wants USD 500 Million refund from NHIndustries (NHI). Sweden has announced that it is bound to follow its neighbor country in retiring the NH90. Unlike Norway, Sweden has envisaged a gradual withdrawal of the NH90 from use in 2024 with the entire fleet retired by 2030. Both countries have decided that the NH90 is definitely not able to meet the needs of the Armed Forces. France and Germany are said to have changed the NH90 maintenance scheme trying to keep theirs in the air longer. And the list is not complete without Belgium: the country wants to replace its army NH90TTHs by Airbus H145Ms. Australia’s neighbour, New Zealand on the other hand has been quite satisfied as they are getting acceptable flying time from their eight NH90s. However the situation can change. The decision to select the NH90 at time was partly influenced by the fact that Australia chose the type, making future modifications easier (and cheaper) and ensure interoperability. Now Australia has decided to say goodbye to its NH90s, one wonders what New Zealand will do. This especially in respect to the future replacement of New Zealand’s Kaman Seasprite Naval helicopters. |

With fewer than planned-for users, will the price/availability of spares be worse? Possibly not so bad for us given our relatively basic fitout?
