We're not configuring half the RN to do small stuff, we're taking the existing class of MCM vessels (something like 12 in all) and also the River class OPV's plus a pile of other vessels and replacing them with a single, larger, more flexible hull that can do MCM if needed, easily handle extended patrols, sea control duties, and can easily overwhelm any number of blokes with RPG's as needed. They could also take on a large chunk of say, the Iranian Navy and come out on top as they're largely using small boghammers etc - 40 knots won't outrun a burst of 76mm or a Wildcat firing Sea Skua or the latest beam rider from Thales.

What we're not doing is the thing 1805 is always protesting the RN does and gold plating it by fitting it with kit which it won't need for the role and which will compete with resources for the Type 26. By not fitting with or for roles it's not designed to handle we can buy more of them and have a reasonable chance of rounding out an otherwise depleted fleet.


If you start specifying FLAADS/Artisan plus other "GP" fit items, the cost goes up and you're basically going to lose type 26's to this cost spiral.

Nothing wrong with working in space for RAM (twenty tons of topweight and needing little support other than a basic search radar) and by all means leave some hard points and power worked in for Exocet if it can be done easily but let's not make this thing £200m or more by tacking on extra kit.

Once you equip with a Wildcat you have included most of the offensive capability of a frigate it makes sense to include modular options for 1/3-1/2 to be equiped to deal with a sea skimmer fired from the shore, or help out with ASW in a major Falklands type operation.

There would be no point in SSM, but a fit of say 16 CAMM or alternatively RAM. T26 numbers will be low why not anticipate and focus on a fewer highend ships and have the option to back up with 8-10 TAS. the advantage of a modular approach would be near 100% availablity you to available active ships.

even if the ships fully fitted did cost £200m it would only be a c£100 marginal increase for as you would be spending the £100m for the C3 roles anyway. I am assuming patrol and survey work can be dropped in a major crisis. So if 8 ships fully fitted a cost of say £800m worth the sacrifice of a couple of T26. Its the 80/20 rule, these ships would give you in a single role 80% of capability for 20-25% of the cost.

I your opinon (and in fairness the RN for what thats worth with their track record) based on the assumption that sufficient numbers of T26/T45 are available. However how realistic are these number?

To be clear I don't think we are not talking about fully arming all these vessels, but a Stanflex modular approach, prehaps a 1/3 fully armed, 1/3 partial and 1/3 just a gun.

You may not agree with this approach but it is not completely out of the realms of possibility. I find the hostility to this common sense approach quite strange.
Very difficult to make a multi function radar modular in the Stanflex mould, it would probably be completely impractical and therefore very expensive, a better solution would be to add a MFR to all of the MHCP vessals as standard, which would make it considerably more expensive. The costs Swerve quoted for difference between the Dutch OPVs and BAM is £16m, that's basically all down to the sensor mast of the Dutch ships, and they don't have the modular equipment of the BAM, so you'd need to add to it's displacement, you're jack of all trades class are starting to look pretty damn expensive.

I don't consider it a particularly common sense approach for someone to say we won't get enough T26 because they will cost too much and then go and make MCHP much more expensive to both buy and run to compensate.

As Stobiewan says you're needlessly gold plating stuff, and I'd refer you to the LCS programme as a reference to what happens to an inexpensive ship class meant to bought in numbers which gets over spec'd.

I'm not gold plating, I would be happy with a 57mm on all ships for AA/CIWS. 8Phalanx, and a similar number of RAM. The key to it all is numbers and working with the suppliers to ensure there are no fallow periods of construction. If CAMM can't me matched to a cheap radar its doesn't have much of an export future.

c2,500t is a popular export size. The only hot war role I would see it undertaking is ASW with a TAS. Agreed that would be expensive, but worth it.

We could easily leave space for fitting a stabilised Starstreak mount or the like, or even RAM (though that's not in inventory or planned for any other RN ships, so would be a significant extra cost). Mounts for Sea Skua Mk 2 or the like should also be possible, if desired. But however desirable it might be, the UK doesn't have a Stanflex-type system, & developing one, & modules for desired weapons, would be an extra cost.

I presume that like the built-to-a-tight-budget Holland, Thetis, & Meteoro (BAM) classes, MHPC will have some defensive aids, so will not be completely helpless against anti-ship missiles.

As far as not getting enough T26 goes, I understand that BAe has a commitment from the government to build 15 warships, including the two carriers. That seems to mean 13 T26, which could explain why the government is keen to keep the cost of each ship down: it can't save money by cutting numbers. In the circumstances, I suspect we're far more likely to get a full complement of under-equipped T26s (C2 masquerading as C1) than a reduced number of full on T26s (C1) plus up-gunned MHPCs (C2 masquerading as C3).

ASW with a TAS needs extra equipment aboard the vessel to use the TAS & interpret the data from it. It also means getting a TAS from somewhere. We'd either have to deprive a T26 of one, or buy more.

I agree, Phalanx & RAM on the majority of MCM/OPV/hydrography ships isn't gold plating. It's more like platinum or rhodium plating.

How many do you think we're going to get? It ain't going to be two dozen. They won't replace the Hunts, Sandowns, Rivers & Echos one for one, let alone an increase in numbers.

CAMM as per all decent SAM systems needs an MFR to work. You want Phalanx and RAM on it as well? or instead?

2500 tonnes might be a popular export size but I can't see how you're going to get all you want in that displacement, the Holland class OPVs are 3000t and don't have any modular equipment fit or SAM systems. The Spanish BAM is 2500t but only has a range of 3500 miles, doesn't have a radar capable of interfacing with CAMM, and probably doesn't have enough crew space for all the people you're super MHCP/GP Frigate would need.

To be honest I think you should probably just go the whole hog and suggest equiping the T26 for Mine counter measure and hydrography work too, eliminate one class all together because you're super MHCP/GP class is starting to sound almost as expensive.

.
BAM has a much greater range than that. The Armada presents it confusingly, saying 3500 miles at 15 knots, 3500 miles at 12 knots, & so many hours loitering at 6 knots, IIRC. That's actually cumulative, so it can definitely do more than 7000 miles at 12 knots.

Otherwise, I agree completely. It has 35 crew plus room for another 35. Add lots more equipment & weapons & you might have to cut into crew space, & unless we revert to WW2 crew space allocation, we'd have great trouble fitting in the crew numbers needed. Of course, if we did that, we'd no longer have any overcrowding, because we'd lose too many recruits to be able to man the vessels.

I guess that will teach me to read things properly.

It always makes me laugh when I see people quoting WW2 era displacement figures as a means for how large a modern warship needs to be, it always makes me think of hammocks.

I've never been a fan of trying to weapons onto a small ship so would concede to the knowledge of Swerve etc and this idea that you can change the fit of a cheap patrol vessel "if it needs to defend itself" seems ludicrous.

I'm no expert but defend against what? The link below is a study of a Type 23 Ops room, now this is a ship designed to fight high end with already a small crew, with lessons learnt from the losses in 1982. Its quite boring stuff but it does suggest that "defending itself" is a rather more complicated task than bolting on a few weapons. The Ops room of a Type 23 requires 15 people to crew the systems at anyone time, now with the watch system thats a lot of crew to work 24/7. Then add the officer on the watch and all the other functions of a ship.

Arent these new MHPC supposed to be lean manned, 30 or so crew? Isnt that the idea, cheap as chips to run? So surely once you start trying to add the ability to defend itself in a proper hot environment , the size, complexity and complement increase would be astronomical? Maybe there is a playstation type console you can add so a single crew member can fight the battle space with these bolted on CAMMS/ SSM. TAS? but I doubt it and haven't seen anything on line that suggest anything of the like.

http://bura.brunel.ac.uk/bitstream/...wareness_in_dynamic_systems_Stanton_et_al.pdf

I would suspect the RN has it right, to defend against a semi decent and determined rival with his own ships, aircraft and subs, you need a very complex and expensive ship, tying to do it with a pimped up patrol ship seems a recipe for disaster.

My two pence anyway , although the small ships are best debate was done to death a while back in these pages.

Just another question for the more technical minded, to drag a TAS arent you putting extreme stress on the ship? Can a small ship of 2000 tonnes really drag one through terrible sea conditions and last long? wasn't that why the Type 23 was scheduled for a short life as it would have been slogging away in the north atlantic dragging a TAS? Doesnt a dedicated TAS platform really require a specialist and suitable robust hull from the start?

Don't know myself but it makes sense that if you're dragging a bloody great TAS around then you need a pretty strong hull to do the job, also probably need a beefier propulsion fit too.

Instead. Actually to make this easier I would build something very similar to the Abukuma class. But without SSM/ASROC but with a hanger for a Wildcat. Bearing in mind this design is 20 years old and doesn't have mission modules. I would also see a basic engine arrangement giving 25knots, automation likely to have a maximum including mission crew of c100.

You're maximising flexibility of individual ships, when the fleet is not under resource pressure. Once the pressure's on, & ships are needed for their main roles, that flexibility becomes difficult to use. An RFA can't do MCM when it's accompanying a carrier group to provide fuel or other stores, nor can an LPD full of troops.
We will always have a finite number of RN ships, that's not the point. The point I am making is that with technological advances MCM / Survey capabilities are able to modularised, which are relatively easier to move from vessel to vessel. Warfighting capabilities including weapons, sensor fit, survivablility etc are not.


Here we go again . . . how can they do this role quickly if they're otherwise occupied? You can't make a ship be in two places at once, doing two different roles, just by making it capable of both. And no, I'm not saying it would be quicker to build new escorts (it would, of course, be quicker to upgrade the MHPCs), but that the WW2 scenario is an inappropriate comparison, since we're not equipped for it & wouldn't be whatever C3/MHPC we build. In that environment, we'd be doing everything at once, up to the limit of our physical & financial resources. That isn't the world we're in now. We have a limited budget, & it is NOT going to increase. We don't have the budget for your ships.
Again, the point I am making is that in a serious war the C3s would be quickly upgraded to be escorts, not used as MCMVs unless that was the priority. With MCM / Survey capabilities modularised, building new MCMV or adapting merchant vessels would be quicker. I think we do have the budget for these, it's just that the MOD (wrongly in my view) has prioritised other capabilities. For example, a £150M ship represents about 1% of the UK High Level Defence Equipment & Support Budget (based on 2007 / 2008 numbers).

Exactly. Which is why we can't multi-task the high-value ships with jobs that can be done by low-value ones. They have other things to do.
The point is that we need to maximise the use of every vessel. As per my previous comment, MCM / Survey duties could be given to non-RN vessels if none are spare.


Development and production. Comparing system price, including fixed costs such as development costs for a radar, engine, & much else, with the unit production cost of a ship using OTS equipment is not valid. We can't save any of that development cost by diverting money from the Typhoon programme to ships.

The production cost of a Tranche 2 Typhoon (what's currently building) is 55 mn euros..[/QUOTE]

Typhoon Tranche 3a are estimated as 90 mn euros (not including development costs) which is £80M at the current exchange rate. The Typhoon is just an example, as I say the money we are talking here is less than one percent of the total equipment budget.


Short for the RN. There have also been 'peacekeeping' (really peace enforcing) missions, where there was no threat that a BAM couldn't cope with.
Really? Which peace enforcing missions were you thinking of?

We're not configuring half the RN in this role. We're configuring maybe a third of the RN as multi-role vessels, which can, among their other capabilities, function as OPVs.
You are replacing 14 MCMVs, 4 Patrol Vessels and probably 2 survey ships - that's 20, that's half of the RN signifcant surface fleet in my book.

On the one in three rule, Somalia is currently absorbing SIX escorts. That's a third of what we're heading for. If we had some smaller, cheaper warships we could cover that with a fifth of the manpower, & far less cost.
This is before the T22s were withdrawn - are we still expecting to commit two going forwards? You are probably freeing up ships that are already on the scrap heap.

Yes, we have two out there. And the speed that matters in this role is the helicopter speed. We've deployed RFAs for the same role. I've not noticed that they're faster, or have better sensors.
Like Fort Victoria which is armed with CIWS and has a Type 993 3-D surveillance Radar - doesn't sound like the MHPC you've been describing.

BTW, the MHPCs should be better able to defend themselves than our current MCMVs, which we deploy to the Gulf.
Absolutely true, but we also have a gulf patrol frigate (HMS Iron Duke currently I believe), would your MHPC replace this also?

True that most of Iranian military hardware is more for show than bite. But they do have things such as midget submarines and costal missile batteries which could easily blow a MHPC out of the water hence the need for proper escorts in the area.

I don't believe that what we are talking here is to make the C3 into the C2. Looking at developments such as Vulcano projectiles for naval guns is an example where people have thought of ingenious ways of upgrading standard equipment without drastically increasing the base cost of the vessel.

The current Khareef class being built for Oman by BAE in Portsmouth is an example. £400M for 3 vessels which includes a training package (£133M each). Again, I don't expect the C3 to be armed with Exocet as standard, but the 12-cell VL Mica launcher is an interesting addition.

Abukama without SSM and Asroc but with a hangar is basically the Navantia BAM, which is where we started..and BAM has a crew of forty.

Needs to be a bit quicker for your spec but otherwise, job's a good 'un?

No FLAADS then?

Yes, but they have a sonar fit and where designed for TAS (though never fitted), they also are faster 25knot. Personally I would have thought a modular form of CAMM would not be as difficult or as expensive as those on here claim, particularly as I thought a version was planned to replace Rapier....but I give up and would accept a 57mm & a CIWS. But I stress I would only have 8 ASW equipment sets, so in a crisis we could say field 8 T26 & 8 ASW focused light ships, but could field 30 hulls for patroling (6 T45, 8 T26 & 16 of whatever we call them.

Probably going to need to add at least 500 tonnes to that for the mission modules and the hanger, also I suspect the range is a bit limited.

That's because you're not thinking it through, just to repeat it's not CAMM that is the problem it's the MFR it needs to work, you can't make this modular without a great deal of work and an MFR is way beyond what we would expect to put on an MHCP vessel, it adds to displacement and cost, in answer to your earlier point RAM also needs a decent MFR to work, although SeaRam doesn't.

Use of Volcano ammunition could be useful for the MHCP, it would make into a useful gunboat at relatively low-cost.

The Khareef is it stands is 2500 tonnes of ships that don't do anything that MHCP requires, can do the patrolling but not at the range we want, no potential for Hydgrapic surveying or Mine counter measures. The Khareef that was offered to the MOD as meeting the the C3 requirement was substantially modified and had a displacement approximately 500 tonnes heavier.

I don't think any particular one vessel in service anywhere is what we want. What quite a few people on this forum are saying is that we cannot make the C3 into a more useful warship without making it into a C2 and somehow bankrupting the country, with a bit of thought using technologies like volcano ammo or VL micro launcher I believe we can.

Also, I don't personally think that range has to be a key requirement especially if for significant operations they were with a JSS.
