OPVs

http://www.defense-aerospace.com/cgi-bin/client/modele.pl?session=dae.4308111.1089903978.QPadasOa9dUAAESlMZk&modele=jdc_34

Another version of an OPV.  Starting to get up in size and not ice-strengthened but relatively fast at 24 knots and has a heli-deck.
 
It does not meet 2 requirements that I can think of right away.....for the OPV to be about up to 1700 tonnes and for it to be ice strengthened.
 
Just a thought - keeping with DND's tradition of recycling equipment wherever possible, would the 35mm AA guns that are set to be retired provide suitable armament for the OPV?  Or would a heavier gun be required?  I notice that the Italian OPVs and corvettes use the 76mm OTO, the same gun I believe as what our destroyers use.

I guess the question that needs to be answered is the what is the role the OPV's would fill?  Are they going to be limited to doing fishery patrols and inspections of merchant vessels in Canadian waters, or could they be deployed in foriegn waters, say to protect supertankers from small go-fasts in the Persian Gulf?
 
Things change but the primary role of the OPVs will be for Canadian waters to free up the CPFs and destroyers more or less for overseas missions. While the 35mm are nice we already recycled the 40mm and put them on the MCDVs and ended up with a barely functioning system. hopefull they will buy 76mm Oto Melara's so these ships will have some teeth.
 
Barely functioning how? I was out with the IST's a while back and it seemed fine....
 
I have seen so many OPDEF messages come across regarding the 40mm not working since the MCDVs came out its down right scary. They need a new main armament pure and simple.
 
Hey again Im sure you'd know better than i do. Ill ask around when I hit the coast next week. We didnt have any problems with them at my last shoot but like everything else Im sure it could stan to be replaced.
 
Agreed...I don't think you guys would mind having newer and better kit. I know we never do.
 
I think this is the vessel the New Zealanders are buying from Australia (2 of them) along with 2 30-35m inshore vessels and a small multi-role vessel (capable of transporting 250 troops with LAVs) all for 500 MNZDollars or about 427 MCAD.

Designed for the Roaring Forties and Ice Strengthened.

This ship has been developed in conjunction with the
Royal Australian Navy to meet the operational requirements
of the region. The ship has been optimised for seakeeping,
endurance and surveillance roles.

80 metre Offshore Patrol Vessel
An 80 metre vessel developed specifically for naval operations and support in the region

Construction
The hull is a shallow draft round bilge form with fine V sections forward.
It incorporates a spray rail forward and a trim wedge aft. The hull and
superstructure are of welded steel construction designed to meet
Classification Society requirements for unrestricted service.
Propulsion
To provide a high degree of flexibility, the main propulsion systems will
comprise a twin shaft arrangement with each shaft being driven by a
medium speed turbo charged marine diesel engine. Slow speed operation
is accomplished using an electric motor connected to each gearbox.
Sea Keeping
The vessel is optimised to provide excellent seakeeping and endurance.
Seakeeping has been extensively tank tested by MARIN of the
Netherlands. The vessel is ideally suited to long, arduous operations in the
ASEAN region.
The ship is designed for unrestricted operations including all weapons,
sensors and other equipment (including intermediate sized helicopter
operations) in Sea State 5 conditions.

From the CASR site. Talks about retaining SH60s if we get them for the OPVs if we get those:

the hard part would be getting the government to buy the seahawks that the US navy has. :)

RN River Class OPV has been redesigned for Falklands use - Ice strengthened and Merlin size Heli-deck.

Just another option - these vessels are leased and civvy supported but Navy crewed.

Looks like the navy OPVs won't be happening - CMS is keeping his eye on the JSS ball and doesn't want to lose it by considering other "priorities", and the Coast Guard has had funding approved for a project for six Mid-Shore Patrol Vessels and a fewer number of larger fishery patrol vessels.

As Martha would say:  "It's a good thing!".
 
Recent MERX call for proposals for the Mid Shore Patrol vessels.
