Re: Current & Future Escorts - General Discussion
On the Type 45, if you were to rip out ALL the Sylver silos, how many Mk41's could you fit between the gun and the superstructure?

Re: Current & Future Escorts - General Discussion
I do not think T45 needs TLAM. For me, it is very low in priority. T45 is a primary AAW asset. Strike shall be provided by CVF itself, which is designed to provide "strike".
On the other hand, adding Mk.41 VLS is can be regarded as "for SM-3" BMD missiles. Note that Mk.41 VLS itself is not expensive, but the TLAM control unit and/or SM-3 system integration is much more costy.
Also, the proposed locations for "more CAMM" is very interesting I agree. How about the bow? Modern escorts has a covered-deck with big anchor handling space at the bow. I understand the space is not full, and adding narrow ExLS there will be easy.

I'll comment on those above in reverse order:Poiuytrewq wrote:Another possible location could be in one of the boat bays adjacent to the hanger. This area of the T45 has lots of under-utilised space
I am very much in favour of using the sides of the helo hangar, as they have done on the Canadian Halifaxes
- but, I read somewhere that this goes against RN policy and access between different parts of the ship must be there, on the deck, too
As for the first one, we are changing the modus operandi and T45s will not need to ' do singletons' anymore (much)
- a native helo is therefore not a must anymore (the helo deck is)
- use all of the hangar! Can we afford to fill so many silos? An arsenal ship, at long last

Re: Current & Future Escorts - General Discussion
I think the program will be cancelled. The basic idea is to chose an existing ship that can be modified & built quickly to meet a USN requirement that no existing ship can meet. I don't think that can be done.Poiuytrewq wrote:Who in your opinion is the favorite?Ron5 wrote:As for FREMM being a favorite for the USN, I'm still laughing. Not a hope in hell.
Personally I would like to see a Legend Class derivative win but maybe that's wishful thinking as I am a big fan of the design. Has Ingalls even confirmed which design they are putting forward yet?
As our armchair friend has pointed out, the requirement amounts to a mini Arleigh Burke that can catch submarines at a third to a half of the price!!!
I think the program will be cancelled and be replaced with an AB replacement program plus more fighty LCS.
Re: Current & Future Escorts - General Discussion
I'm afraid your question scored an F. In transferring equipment from the T23 to a T31, nothing is being replaced so DRC is totally irrelevant. But thanks for playingArmChairCivvy wrote:Ron5 wrote:It's quite simple.

- they won't come dirt cheap (that would be a result from straight-line depreciation, and resulting book value)
- as military inflation tends to be so high, there is something called Depreciated Replacement Cost (DRC), to obtain which indices are used to revalue the asset (which then is followed by the "normal" depreciation calculation)
In the prgrm context the above is by no means limited to the sonar transfers, but is a universal principle
So if the kit costs $10m brand new and the usable life is set at 20 years, after 5 years the book value is $10m x 15/20 = $7.5m. After 10 years it is $5m and after 20 years, it is zero.
But, and it is a huge but, book value is not real money, it is not cash, it is an accountants concept. The real money, the cash, has already been spent.
So mixing up actual cash that will be spent and an accountant concept of "virtual cash" which is solely used to spread the budgetary hit by large infrequent purchases of capital equipment is a major no, no. But of course the MoD and Treasury do it all the time. The effect to to leave the impression that more money is being spent than actually is. It's fake news.I did my best, time to read the exam question again.Ron5 wrote: Depreciated Replacement Cost (DRC)

No, not even close. The book value of an asset under the RBA used by the MoD is not based on its theoretical replacement cost but is based on it's actual acquisition cost spread over its useful life. There's a couple of downloads on the MoD site that explain their accounting methodology. You might find them interesting.ArmChairCivvy wrote:"R" in that means that the original "book" cost cost is revalued and the, in itself simple, straightline method run then, based on the "new" number.
By the way, many thanks to your pointer to the book on the history of UK sonobuoys. I'm half way through and its fascinating.
Re: Current & Future Escorts - General Discussion
TLAM is a political weapon as far as the UK is concerned, we will never have enough to be able to launch a meaningful strike, but they are good at saying that we are taking part. As for fitting ExLS to the T-45, this would be a piece of cake funding permitting. The three cell standalone could be fitted relatively easily, and it is very compact. Each carrying 12 Sea Ceptor (Why do people keep calling it its old name?) and we end up with a platform with 48 Aster 30 and say between 24 and 48 of the former by installing two to four ExLS launchers. You do not even have to penetrate the deck ot install them except for wiring. The RN could treat the standalone like it does Phalanx and have a pool shared amongst the fleet with as many vessels as possible plumbed for the system.

Re: Current & Future Escorts - General Discussion
Sea-Ceptor or CAMM in addition to ASTER 15/30 on the Type 45 makes a lot of sense. It might enable the number of T45 Escorts for a QEC Carrier to be reduced and therefore stretch farther across the Fleet. If the Type 31 (or a variant) could become an effective ASW escort as well, then it might enable the number of T26 Escorts for a QEC Carrier to be reduced also. Between 1 x T45 and 1 x T26 the number of CAMM would be very little different from the 2 of each accepted hitherto. Of course the T31 may bring some CAMM to the party as well!

Re: Current & Future Escorts - General Discussion
1) you can't reduce the number of T45 any lower than 1, which is what the CBG will have routinely unless 1) for a photo opportunity, 2) shit hits the fan, or 3) the CBG meets an additional T45 which is deployed near the CBG or is transmitting near by.Scimitar54 wrote:Sea-Ceptor or CAMM in addition to ASTER 15/30 on the Type 45 makes a lot of sense.

2) the T31 will have no ASW capacity of any value unless the scope of the programme, and budget, is increased. As it stands the only thing the T31 is likely to contribute to the T31 is 12+ additional Sea Ceptor

Re: Current & Future Escorts - General Discussion
Unless I misunderstood your point, you suggest that the carrier(s) could be deployed with fewer T45 escorts if Sea Captor were added to the T45s.Scimitar54 wrote:D M

My point is that I'm guessing the carrier(s) will only typically deploy with 1 T45 anyway, irrespective of whether Sea Captor has been fitted or not.
Given the low number of escorts, and the manning issues, I can't see a typical UK carrier group in peace time comprising more than:
1 QE
1 T45
2 T26/T23
1 tide
1 SSS
This will occasionally be augmented with whatever RN assets are also operating in the area and allied vessels.
Even so, with 18 or so F35s and the associated helicopter wing, that's a pretty badass force that only a handful of other nations can match. And, we'll have two such groups (though likely only one with a fixed wing airgroup) providing year round availability

Thank-you. I was suggesting the possibility that the escorts might be able to be comprised of 1 x T45 and 1 x T26 plus 1 (or perhaps 2) T31 suitably upgraded to conduct ASW. The (extra) CAMM that might be carried by a T45, would offset the reduction of a second T26 (for it's CAMM) and the loss of the ASTER 15 on a second T45.
In that way, suitable escorts could be released for independent deployments. The CSG escort could obviously be re-inforced with the additional vessels (and/or an SSN) as and when required.

Re: Current & Future Escorts - General Discussion
The key here is "continued and long term use". That's things like land & buildings that can last for hundreds of years (fixed assets) not items like guns and sonars which have a defined usable life. Seeing that we are discussing transferring sonars & guns from the T23's and not bricks and mortar, this is totally irrelevant. As I have stated before, book value of the guns & sonars will be based on their actual acquisition cost, not a theoretical replacement cost.ArmChairCivvy wrote:Well, the "how to do it " guidelines were circulated in 2012 and are still in force.Ron5 wrote:The book value of an asset under the RBA used by the MoD is not based on its theoretical replacement cost but is based on it's actual acquisition cost spread over its useful life.

Re: Current & Future Escorts - General Discussion
OF course it would be better if we stuck 4-6 3 Cell ExLS (48-72 Sea Ceptor) onto the QE and PoW to dramatically increase their fire power. The lack of the above is as bad as the UK's policy on how to organise the air group for the carrier. I can only see a T-31 joining a Carrier group if it is part of a PR photo op to try to convince people it is a proper warship. 1x T25 and 2x T-25 with a SSN when one is available and of course FRA support, of 1 tanker and 1 Solid stores platforms.
In fact how the T-31s are actually used when they enter service is going to be quite interesting, will they be given duties that are appropriate to their actual capabilities or are we going to have the naval equivalent of the "Snatch Land Rover" mess, where a platform was used in situations for which it was neither designed or capable of handling.

Re: Current & Future Escorts - General Discussion
We should keep the TLAMs solely on the SSNs with the Astute successor being fitted with a VLS for them. We rely on the systems as a surprise strike weapon fired in twos and threes. Having them on an SSN also allows the UK to bluff opponents by announcing a SSN is moving towards an area even if one isn't. It will only be worth installing TLAM even on the T-26 if we greatly enlarge out inventory of he weapon by a considerable margin.

Re: Current & Future Escorts - General Discussion
I struggle with the logic of current planning regarding the T45 and TLAM. Why invest so much time, effort and money in a Frigate design big enough to accommodate strike length Mk41 cells when we already have 6 hulls in the water capable of receiving them? It seems bonkers.shark bait wrote:It should be there for compatibility with the T26 and future cruise missiles.donald_of_tokyo wrote:I do not think T45 needs TLAM. For me, it is very low in priority

I understand the argument that the T45 is an AAW platform and also conducting strike operations at the same time is problematic but the simple solution is to send two T45's. Do we really think that in a conflict situation a single T45 will be looking after the entire CSG? No chance.
This is why I think we should give the T45's the full TLAM capability and downgrade some of the T26's to simple CSG ASW escorts and try and get more hulls in the water.
Even if the first 3 T26's got the full Mk41/TLAM setup and the remaining hulls were built to a basic 24 CAMM non TLAM spec, it would still provide 9 TLAM capable vessels in the fleet. Do we really need more?

Re: Current & Future Escorts - General Discussion
Taking 3 VLS modules off the T26 is going to save peanuts, the modules cost about three million a piece.
I don't think conducting AAW and Cruise Missile strikes at the same time is at all problematic, the Burke class has been doing it for decades. I would say its preferable to use the Destroyers for that role, if the RN go popping off a few cruise missiles that can expect to see a few coming back in their direction. The French and American ships we're on high alert for such an event for days after the Syria strikes.

Sorry Ron, the MoD have a lot of downloads about the changes they make to their reporting. As RAB happened at the beginning of this millennium, the changes since may make interesting reading (for understanding the published figures):Ron5 wrote: As I have stated before, book value of the guns & sonars will be based on their actual acquisition cost, not a theoretical replacement cost.
"The MOD is one of the largest owners of non-current assets in the United Kingdom. The

This valuation method complies with financial reporting standards with values being on an existing
use basis rather than market value at disposal. Overseas estates for which the Crown holds no
legal title, but which are used for garrison and training purposes by British Forces, are included in the MOD non-current assets register. UK bases occupied by visiting forces are also included.
As at 31 March2017, the value of MOD non-current assets stood at £130.6 billion
, which is a rise of £2.8 billion compared to the
figure for the previous year. The recent increases in value have
been caused mainly by the reclassification of inventory as non-current assets.
The largest value non-current assets were Single Use Military Equipment at
£33.1billion and Land and Buildings worth £31.6billion. "
What's £2 or 3 bn between friends? The sums are so big that no one would have noticed.
