Re: River Class (OPV) (RN)

Hi Donald, I'm intrigued by your proposal. It's clear you have given this a lot of thought :thumbup: First question, for deployments like APT(N) or Falklands patrol, does an OPV really need a Merlin capable flight deck? Would Wildcat capable be enough? Is this the compromise that could allow the RB...

Re: River Class (OPV) (RN)

Thanks ...When I thought about this in the past I generally came to the same conclusion, they're just a little bit too short, so i'm very intrigued by your proposal to extend them. I didn't know such a stern extension was possible, could you expand on that part please? Not sure enough, but there are...

Re: River Class (OPV) (RN)

.... The 5 B2 Rivers are right for FRE, surveillance and anti terrorist operations in UK and BOT EEZs - with some enhancements they can also play a role in layered ASW defence also. I was thinking of this for the new year period. Although a bit fantasy, this is my thought. The main aim is to 1: Add...

1: PoW is the primary "LPH" I fully understand between 2010 and 2015 a 'role' had to found for PoW to avoid it being cut and Ocean without replacement was part of the sacrifice but for how long are we going to have to keep up this charade? We don't need a £3bn LPH. We could have built 10 ...

Re: Current & Future Amphibious Capability - General Discussion

The reason why Bay-class LSD is used for APT-N and not Albion-class LPD is clear = much efficient. The reason Albion isn't used for APT(N) is due to its lack of Aviation. It's a massive oversight with the design just like the RB2's. We mustn't make the same mistakes again. I think it is more the is...

Re: Italian Armed Forces

A question, would M-345 be so much cheaper than M-346 so that Italian Air Force will have two pretty similar aircrafts in service? I think yes. I think these two is NOT pretty similar. M-345 is designed to be as cheap as a turbo flop trainer (not sure if it was successful). The original S211 was de...

Re: River Class (OPV) (RN)

As far as a new UKCG ship goes maybe something like the 62 meter Vita with a Scanter 4100 radar would be a good fit with a 35 knot top speed room for 2 ribs maybe even a Hero or Camcopter S100 with I Master radar I'm afraid it is way too expensive. Damen 4207 will be much better; cheap to build, op...

No scan eagle to search, no MPA, and no data link on the helicopters to send live video to the patrol vessels. = Utterly unprepared.

On the assets to be forward deployed. I see no problem sending T31e. Any of the Leander, Arrowhead 140, and MEKOA200 (?) is a perfect match for, at least some of those tasks. 1: Against China or Russia, its modest fighting power is not a problem, even a T45 or a T26 is "nothing" in their v...

Re: Current & Future Amphibious Capability - General Discussion

The 3rd flat top must not, and will not have (because of lack of F35b), any F35 to be carried. No need, RN has two CVF, that is enough. The point of LPH is to keep the air asset far beyond the horizon. A ship with well dock must be located near the shore, which is totally not needed for LPH. As PoW ...

Re: River Class (OPV) (RN)

"USVs" and "CAPTAS-1" both are applicable to Type-31 frigates . As can be easily imagined, adding (even) CAPTAS-1 to T31 will be very promising. But, as ASW-USV can be carried on 5 River B2, 5 T31e, 8 T26 (and even 3 Bays, 2 CVFs, 8-10 (?) MHCs (or 2 Echo)), it is more worth tryi...

River is 13.6m wide and 90m long, so it can go anywhere. Israeli SeaGull USV is good that they worked in sea state 5-6, but it is not clear if it is also true for ASW (I understand it was on MCM). This two things are both promising = good things. But, I agree USV option will be "more advanced&q...
