I still have some unresolved thoughts about optimal NZ patrolling within/outside of NZ's EEZ and into the Pacific (and Pacific Island EEZ's), the counter terrorism and peace keeping roles etc (i.e. the lower threat level stuff, not a shooting war scenario, but possibly also I'm thinking about the first things that could happen should "things start to go bad" e.g. the laying of mines, e.g. from disguised foreign fishing trawlers not so much a hostile warship as intelligence would most likely know of their existance etc. A sub might be a different matter of course, but I'm aware that there are/were underwater acoustic listening devices....).Having thought about the issue some more in regards to the OPV I'm more of the view now that any upgrades besides the main armament, should focus on developing Modular MCM, Environmental protection modules etc.
I think recce.k1 was referring to the LCS modular minehunting modules. Unfortunately, the OPVs don't have the same CICs, therefore, the system won't work with the OPVs. AGAIN, someone is attempting to get more out of an OPV than patrol. Get a clue, a NZ $90 million OPV ship will never be a NZ $500 million frigate, or a NZ $500 million littoral combat ship.I still have some unresolved thoughts about optimal NZ patrolling within/outside of NZ's EEZ and into the Pacific (and Pacific Island EEZ's), the counter terrorism and peace keeping roles etc (i.e. the lower threat level stuff, not a shooting war scenario, but possibly also I'm thinking about the first things that could happen should "things start to go bad" e.g. the laying of mines, e.g. from disguised foreign fishing trawlers not so much a hostile warship as intelligence would most likely know of their existance etc. A sub might be a different matter of course, but I'm aware that there are/were underwater acoustic listening devices....).
Firstly, to the unitiated such as myself, what do you mean by "modular" MCM (and environmental protection modules) and how would this compare with the current methods of MCM as practised on the IPC's?
Exactly. Patrols ships we certainly needed. We probably need another pair to go with them, but not for "combat" duties. You simply don't need a frgate to sail around the Solomons a few times a year. Or show the flag in the South Pacific.Don't expect more out of these OPVs than this. They are not warships, they are patrol ships.
The OPV's have a spot on the quarter deck for a ISO 20 ft container and two special forces RHIBS. Any modular concept revolves around using this space. There would be a requirement to install plug in electrical sockets etc. By modular I mean equipment that can be loaded for mission specific tasks. For example the Coastal Tanker runs aground. The OPV pulls into a port, loads an environmental protection module: Dispersent, Deployable oil boom etc and sails. The concept is becoming popular overseas with the Dainsh SF300 and the USN (overpriced) LCS.I still have some unresolved thoughts about optimal NZ patrolling within/outside of NZ's EEZ and into the Pacific (and Pacific Island EEZ's), the counter terrorism and peace keeping roles etc (i.e. the lower threat level stuff, not a shooting war scenario, but possibly also I'm thinking about the first things that could happen should "things start to go bad" e.g. the laying of mines, e.g. from disguised foreign fishing trawlers not so much a hostile warship as intelligence would most likely know of their existance etc. A sub might be a different matter of course, but I'm aware that there are/were underwater acoustic listening devices....).

Just so I am clear on your thinking, I assume you are thinking along the lines of a Frigate etc will have hull mounted sonars (and perhaps towed array sonars) to detect underwater objects, such as mines (or subs, especially if a tower array is deployed)? With the hull mounted sonar, the Frigate crew would be able to continuosly monitor for underwater objects? The NZ OPV on the other hand has no such capability, nor probably should one retrospectively fit such a system if it were not already designed "to be fitted for" such a system and with space reserved etc? Although if one could, the cost of fitting out the OPV would increase its price a lot more, thus (when other systems and weapons are taken into account) it's better to buy a properly outfitted Frigate rather than try and cram all this into an upgraded OPV?I think recce.k1 was referring to the LCS modular minehunting modules.

This sure sounds do-able with the added bonus of mix and match to the needs of the mission etc. For peace-time purposes or possibly for low-threat UN/Coalition peace-keeping purposes this presumably could work out reasonably well (although I assume detection ranges are smaller than a Frigate with dedicated sensors)? I assume this is all well and good if the OPV is actively searching for mines etc, but I wonder what would happen in a wartime situation if the OPV is in transit, without hull mounted sonar and I'm assuming the MCM drones aren't always deployed especially in transit, and runs into a minefield? Or am I wrong, are there sensors operating 24/7 in this modular system to detect and avoid minefileds etc?A modular MCM capability would consist on a portable decompression chamber http://www.msi-dsl.com/diving.html for a diving team, Remus and MCM drones with side scan, similar to that used by the RAN.
SHIPYARD TO CLOSE
07.05.2008

The launching of Whangarei's "own" inshore patrol vessel in a few weeks' time will mark the death-knell of the company that built her, Tenix Shipbuilding New Zealand Ltd.
Company manager Alistair Taylor yesterday confirmed the company will close down by the end of the year with the loss of 60 full-time jobs at the Port Rd site.
Mr Taylor was in the same position as everyone else in the workforce - "I'll be looking around to see what work options are available".
Workers have already been leaving, but about 150 remain at the Tenix base. About 90 of these are sub-contractors who will return to their own sites.
Mr Taylor said the closure was no surprise.
"We've lived with this for quite a long time.
"We have always known that this was a possibility at the end of the project," he said.
The pending billion-dollar sale of parent company Tenix Defence in Australia - the buyer is believed to be British Aerospace - had been a factor in closure becoming a certainty, he said.
The workforce had been gradually winding down, with about 16 already moving to jobs in Whangarei, Australia and even the United Arab Emirates.
Mr Taylor said he "preferred to focus on the positive of the tremendous achievement completion of the contract represented for skilled Whangarei workers and sub-contractors".
Australian defence and technology systems group Tenix won the New Zealand Defence Project Protector contract to build seven naval vessels about four years ago.
The $500 million deal for a 8870-tonne multi-role vessel, two 1600-tonne offshore patrol vessels, and four 340-tonne inshore patrol vessels included provisions to do much of the work in Whangarei - which has brought a $110 million tidal wave of cash to the district.
Tenix in Whangarei has built all four IPVs.
It also built some modules for the two 80m offshore patrol vessels, which were barged to the Tenix base in Williamstown, Melbourne, for completion. The 130m multi-role ship Canterbury was built in the Netherlands, also under contract to Tenix.
IPV Rotoiti was launched last August, Hawea late last year and Pukaki last Sunday. That same day, Taupo - whose home port will be Whangarei - was moved out of the shed to the spot vacated by Pukaki.
The Tenix land and buildings are owned by Port Nikau Ltd, the company that owns the former Port Whangarei.
The seven new vessels in Project Protector will increase the navy's number of ships to 13 and offer a wide range of capabilities.
The Government decided to follow naval tradition in naming the ships after earlier vessels that served in the Royal NZ Navy. The four IPVs are all named after lakes - Taupo, Rotoiti, Pukaki, and Hawea, which were the names of New Zealand's Loch Class frigates that fought in the Korean War between 1951 and 1953.
The names were also used for the patrol craft that carried out resource protection in NZ waters in the 1970s and 1980s.
The two OPVs were named after the provinces with which they will be affiliated, Otago and Wellington.
Taupo is associated with Northland, the Rotoiti with Hawke's Bay, the Pukaki with Nelson/Marlborough, and the Hawea with Westland. The Otago will also be associated with Southland.
I hope you are joking.Its important for New Zealand to keep the factory as is, unchanged, not allowing anyone else to make buses or tractors at this site. That is, unless the government is willing to spend on a new infrastructure again. It isn't easy maintaining a military industrial complex, as the Australians have discovered.
http://www.nzherald.co.nz/section/1/story.cfm?c_id=1&objectid=10509830The navy's Seasprite helicopters have got new teeth.
They have just been fitted with new Belgian FN MAG 58M machine guns to replace the old M60 machine gun
OPV's & MRV were supposed to get an 'obstacle avoidance sonar' according to old press releases & Aker yards design (latter for OPV). Whether they ever got this & whether it has utility in a MCM role I do not know...Just so I am clear on your thinking, I assume you are thinking along the lines of a Frigate etc will have hull mounted sonars (and perhaps towed array sonars) to detect underwater objects, such as mines (or subs, especially if a tower array is deployed)? With the hull mounted sonar, the Frigate crew would be able to continuosly monitor for underwater objects? The NZ OPV on the other hand has no such capability, nor probably should one retrospectively fit such a system if it were not already designed "to be fitted for" such a system and with space reserved etc? ...
...I simply wonder if some of these Patrol assets (OPV's and IPV's) could be pressed into a more aggressive or assertive defensive role? If so, a good cheap investment could be a few more OPV's, perhaps some in Reserve (but on Rotation), with an expanded Volunteer Naval Reserve force to work out on these ships on occassion? A couple more Frigates would be useful of course, but the point of this exercise is to put them to one side for this discussion.
In the Defending New Zealand, it was stated that the Navy didn't get everything they want'ed on the ANZAC's. So a lack of mine avoidance sonar wouldn't surprise me. Its only now been fitted to the Australian ANZAC's (Thales Petrel). I've searched the net to find out the type of obstacle avoidance sonar fitted to the Canterbury and OPV's as the navy website here http://www.navy.mil.nz/visit-the-fleet/cant/recent/mrv-launch.htmI am not even sure whether the New Zealand Anzac frigates ever received their mine avoidance sonar, much less any of the Project Protector fleet.

Wiki don't mention mine avoidance sonar for Ptoject Protector either.

The only information I have found is that the RNZN has three Remus 100 MCM AUV systems. Read link: http://mae.pennnet.com/articles/article_display.cfm?article_id=293821
I assume they are cross deckable.
