The Mk8 upgrade to 155mm was a specific solution to upgrade the RN's capability at a budget, and produce cost savings across the Army and Navy, it was only really an option because it meant reusing mounts. I don't see advantages for any other user unless they already have Mk mounts in service, that restricts the customer base to navies using ex RN ships, the potential for BAE to dominate this market is approximately naff all.
I did say there would need to be a new build option for the Mk 8. However BAE already do have a strong positon in the naval gun market, via mk 45 5", 155mm AGS, Mk 3 57mm. The RN has a requirement for c 19 mounts probably more than most other Navies in Europe together. Although there is a strong pull to 127mm, the greater hitting power of a 100lb v 60lb round plus the same argument about common ammunition with armies would play to most over Navies.

If BAE can mock up a Mk 8 155mm, why don't they suggest a Mk 45 based gun, if adopted I think the USN might follow suit. Either way I could see many other navies being interested.

Who are the rivals in this market, OM: 127mm & 76mm are great and sell well, the Russians, the French seem to be declining in this space and BAE.

Liberated from an AA role, 155mm stands out as the optimum calibre. This is a really useful/core capability, where the RN has probably the largest requirement (other the the USN). We should leverage our positiona and focus on driving OM out of the market.
 
Seriously:

Why the feck does an AAW destroyer need ASuW and LA[C|T]M within the Royal Navy? As a premier escort to the fat-ships they should have:

  • Anti-Surface support [Lynx/Wildcat thro' Dave-C],
  • Escort Arty (Frigates/OPV), or,
  • A couple of hyper-sensitive boats [Underwater, for the purpose of]?

Limited budget but specialised: Works for the 'Special' ones.... :confused:

So suggest it to BAe. If it's such a good idea, with real market prospects, I'm sure BAe will develop it with company money. If, on the other hand, it's only worth doing with a customer already signed up, then BAe won't do anything unless a government steps up with the money. But wait . . . haven't we already been here?

If BAe won't fund it, why should I? I don't want my taxes paying for yet another bespoke, UK-only, weapon system, at much greater cost than buying off the shelf. That money could be spent much more usefully.

I'd recommend state funding for development only if the USN, or several smaller navies, were already banging on the door asking for it, & if they were, BAe would already be developing it, without going cap in hand to George Osborne to pay.

i think we should just stick to the 4.5 until the rail gun technology is perfected then we could use that to replace both guns and ssm's. Also isn't the US looking at laser applications on naval vessels

Type 26 will have been decommissioned and replaced by something else by the time rail gun fits into a 5000 ton GP hull.

I think we should just buy something that works, is MOTS and greatly extends the range and enhances the terminal accuracy of gunfire from a surface ship. That'd be 127mm with Vulcano.

+1, like, wot he sed etc.

Camm is about as far out on a limb as I'd want to go (and that was already in development!)

Let's just stop buying super special stuff for a navy with less than twenty major surface combatants - let's all have a cup of reality coffee and try and pick off the shelf stuff instead?

I would strongly argue against (re-read post and missed out this vital word) going the railgun route, why should we buy a (i assume) VERY expensive weapon than the Oto when the latter is what we should be looking at, a very budget friendly weapon which offers a decent capability jump from the 4.5in? Which - more importantly - is available right now and not many years in the future.

As far as the system goes, I really cannot wait to see how it goes on the Zumwalt, but for the RN? Its a non-starter.

Railguns aren't even rumoured about for DDG so it'll be a while before we get some solid feedback on how railguns work in the real world.

Even when they do work, it's fairly obvious that they'll rely on a large infrastructure, power generation, capacitors etc - such that it'll be a very large chunk of even a 14kt ship like DDG1000.

Parking one inside a Type 26 at around 5kt standard doesn't seem credible.

Well most of the info i've been reading about the DDG do talk about the potential use of railguns in the future. Some sources have been incredibly ambitious and tossed around 2020 as the figure :rolleyes:

BAE have been firing a 32MJ example since late Feb/early March, looks much more like a 'naval gun' then previous lab examples that we have seen, bar the massive bank of capacitors however.

Certainly agree with you there, the Oto 127mm is by far the best choice for the RN.

I'm not sure where railguns would now fit - the DDG1000 has been curtailed to two or three ships and the last in class will only be fully worked up by about 2020 at this rate. First in class would be due for a rework of some sort shortly after but pulling a $150m
AGS installation out and sticking in a completely novel weapon seems a bit expensive.

I suppose it depends on how large and intrusive the installation will be,

Good news, I had no doubts that it would be successful though.

:rwb
I was pretty sure it'd work but it's kind of nice to have something you can point at and go "SEE? SEE?"

There's one guy over on Stratpage has been passionately and eloquently insisting that the damn thing could never intercept a supersonic target due to a mismatch in clock speeds (or whatever else he could think of..the missile being French or whatever)

Almost tempted to pop in and say hi to the bloke but it'll just lead to a tirade about how the test really failed and the result were faked etc.

I've read some of that stuff before, the bloke comes across as a bit of a euro hating crackpot.

I'd love to see this rammed down Lewis Page's throat as well.

Because they won't always be escorting carriers (certainly not for the next eight years). They will be called on to conduct independent operations - as HMS Daring is doing now in the Gulf. They will therefore need to exercise control of the surface and sub-surface battlespace around them without relying on other ships. The T45's constitute around 30% of our surface fleet and in an era of fewer hulls it is important each hull is not nailed to a single specialist role. No other western navy has omitted an ASuW capability from their AAW warships and the reason we have done so is not because we know sometihng they all don't but because we've cut costs (as proved by the T45 not having CEC which is crucial to its primary AAW mission).

A helicopter is all well and good but no SSM's limits the T45 to carry Wildcat instead of Merlin as the latter can't carry Sea Skua. Sea Skua also can't be used against ships with an area SAM capability without risking the helicopter due to its range. And you have to have the helicopter available and properly configured which you can't always rely on (aka HMS Cornwall who's Lynx was refuelling when it was needed to support her boarding crew when they were intercepted by the Iranians)

I'm not sure there's anything to ram down Lewis's throat. I'm delighted that Aster has passed the test but I find it astonishing that it's key capability (shooting down supersonic anti-ship missiles) around which two whole new classes of ships and their radars have been constructed has not been tested until two or three years after those ships were being commissioned. That seems a bit bizzare to me though someone here might have a rational explanation I guess.......

I'm sure we would all love T45s to be permanently fitted with an ASuW missile, but the reality of costs dictate that have to accept the fact that we could add it quite quickly if need be, but for the moment it is not on. However let us get a few facts straight.

  • The T45s do not have no ASuW capability, apart from helos, they also have the nice shiny gun on the front. That might not cover all situations, but it would often be more effective than a missile, especially in the sort of limited ROE situations that will occur at short notice when there is no time to add a missile for a larger outbreak of war
  • Harpoon is not exactly state of the art, and against an area AAW system may not be any more effective than a helo
  • Harpoon would have been no use at all when the Iranians captured the boat crew
  • CEC is not 'crucial' . It would be good to have it yes, but I would prefer a v good radar (Sampson) to old radars (say Spy 1-x) and CEC by far

As for PAAMS finishing testing after the ships were built: how could you do a full system test until they were built. The radar and C2 is part of that system. You wouldn't build a ship around an old and proven missile that is about to be obsolete would you?

1) The original poster was painting a picture that ASuW wasn't necessary. I agree with your point that it has been omitted due to cost not a lack of operational need. We discussed a few posts back some of the capabilities elswehere in the forces I'd be prepared to give up to pay for properly equipped warships. I might also stop the foreign aid we give to India that we begged them not to stop asking us for. That would pay for ASuW and CEC. We can afford it. We choose not to.

2) Sure, they could be fitted. I'm sure if Iran does take any action in the Gulf (or any other aggressor in any other theatre) that they will give us a months notice so that we can do so.

3) I never said the T45 had no ASuW capability. The gun has a limited range against surface warfare targets that would require the T45 to be in the envelope of most of the SSMs that an adversary might carry - not a great idea. My point was about the zone of control ships exert around themselves due to their offensive systems. I think it's better to keep adversaries 80+ miles away from your ship due to it's own SSM's than 15 miles due to its main gun.

4) Harpoon isn't state of the art but it is readily available (the surplus missiles from the T22's) so is available now and cheap. We could then move to a common next generation SSM (that hopefully also has a land attack capability) for all surface combatants when we select the system we want for the T26.

5) I never said that Harpoon would have been useful against the Iranians in the HMS Cornwall fiasco. The point I was making is that there is a danger in having no back up capability to helicopter borne systems as helicopters become unavailable. At least in the SSM role there is a gun as limited back-up but the lack of ASW torpedoes leave the T45 with no ASW capability at all if here helo is not available.

6) You argue we shouldn't fit Harpoon because it is not top rank and then argue that the key top rank AAW enabling technology offered by the CEC is a nice to have. It's a vital to have. Read back a few posts to the ones from the RN guy talking about when they trialled it on the T23 and how effective it was. You create a choice which doesn't exist. We could have Sampson and CEC. We just choose to spend our money on other things.

7) Aster was trial fired from barges. That was where they found there were problems with some of the missiles which delayed their entry into service. There genuinely might be an explanation for the sequence of the testing as I'm far from being an expert but I can't think why it would not have been tested from the firing barge against supersonic targets before building the ships that would carry it. Surely you want to know that your billion pound a piece warships main missile works before you build it?

Supersonic missile simulators cost a *fortune* - the existence of the ships is irrelevant as the missile has existed for many years and that's the system being stressed and tested. Setting up a full scale test using a decent simulator like Coyote is an expensive and difficult test to make.

If you read the GAO's reports on supersonic testing of SM2, ESSM and SM3, it's only the SM2 that is flagged as satisfactory - the other two most prevalent missiles in USN service haven't been adequately proofed either.

Let's get this in perspective, it works, as advertised.

And yes, Lewis needs this rammed down his throat as it's a positive test so ner..
