I do tend to ignore opinions - sorry 'facts' - that come without the slightest empirical evidence to support them or any indication of original thought . In your rush to 'play the man rather than the ball' you forgot to address any of the issues by the way , do you actually have an opinion on Al Faw ?

But no you're quite right , we should accept without question everything our betters do or tell us because " they always know best " and any recourse to an open & free debate about naval matters is entirely out of order on a forum such as this .

BTW living where I do I actually know several Royal Marines personally and I wouldn't 'belittle' this fine body of men at all . Believe me strolling into the Brewers Arms and calling any of them a 'Pansy' would be most ill advised .
I didn't reply to your argument because I felt others had clearly and concisely addressed it already.

I'm not saying we should just get on with things without questioning, but most people here are nothing more than armchair generals, so to think that from talking to the odd squadie and reading wikipedia that we are qualified to tell one of the most experienced fighting forces in the world that we know better is absurd. The Navy knows what it wants and I for one am willing to believe them when they say that a 155mm gun will be useful. They aren't just 4 year olds who want the biggest toy, they have reasonable arguments, many of which have been presented here.

What I don't understand, and what others have also picked up on, in this scale you seem to have in your head, of what requires NGS. So far our examples of Al-Faw and the Falklands have fallen short. Perhaps if we could go back and replay those ops without NGS and compare casualty rates and mission success it'd change your mind. Personally I don't know if the outcome would have been different, but there'd certainly be at least a few more names on a wall somewhere.

And I would NEVER call an RM a pansy, especially not since I may end up having to serve alongside them in the future.

I did understand the new version was lighter than the old Compact but 22t is impressive. Having looked it up online I see the Italian Army is funding development of 155mm versions of Vulcano. I think I would prefer the heavy round, maybe those nice Italians could see if the LW mount could be upgunned to 155mm.
A 155mm Vulcano round would make the 155mm gun argument even stronger obviously. Why go to 127mm as other navies move away.

But why let the Italians do the 155mm gun first, if we get in there with the mount that is already complete, and British, we may actually get some exports. I understand people not wanting to spend money that we don't need to in the present climate but that then precludes any chance of actually earning any later. As the old saying goes "You gotta spend money to make money." When did the British defence sector forget that?

I do agree it would be great if BAe could get an order here, this is one area I would support spending on. Also I assume 155mm Vulcano rounds would fit a Mk 8 based 155m? But either way I think the 4.5" should be retired, not so much the lack of hitting power, as the lack of money to develop munitions...well both really.

A threat to a conventional 155mm could be if the ACS ever became commonly available, but I think the size issue would prevent this? But I am sure the ACS must eventually reduce USN interest in the 127mm.

If I was BAe I would take a risk and develop commerically, the RN will buy it if off the shelf and I'm sure RAN and other would prefer 100lb rounds to 60lbs.

I don't think the lack of a 4.5" hindered the T22s role in the Falklands, there were plenty of other ships that could do the NGS support role. Even if you don't agree surely you would accept the T42 would certainly have benefit from a 76mm + Phalanx along with the reduction of top weight.



I do think that this argument actually strengthens the case for an increase in major surface combatants and the inclusion of a medium gun on all of them when you contrast the numbers of major surface combatants available then and now. Then a few vessels without a medium gun was not a big deal as you say there were plenty of units with one; you should note that the RN has not designed one without since.

I agree that any of the CO’s of the period would have liked to have had the addition of a CIWS (I suspect that the post conflict fit would have been the outfit of choice if given one) and as I have said before it is unfortunate that cost was the major driver in the 42’s design which comes into stark contrast compared with the proceeding County class which although out of date by the Falklands war had the merit of being outfitted with area and point defence missiles, anti surface missiles, a medium gun, 20mm, light weight torpedo tubes and a ASW helicopter which was housed in possibly the smallest most inconvenient hanger this side of a Tribal class frigate.

As to the Type 22 batch one’s they were almost permanently close escort to the carriers but I would point out that all ships operational utility is dictated by its weapons fit and as we know later vessels do have a medium gun.

You mean AGS right? Well at the moment it is only slated for 3 vessels, and it is a very large, heavy, and energy intensive weapon system with no ability to use standard 155mm weapons (a major advantage of changing to a 155mm gun). I don't even know if an AGS could go on a standard frigate sized vessel, I doubt it. I think the USN will stick with 127mm until a new Arleigh Burke replacement can be found, which I don't see happening for quite some time. Apart from that the only orders AGS may get is on CG(X).

What I don't understand with this calibre debate is why no one suggest changing from a 155mm AS90 to a 57mm gun. They're both for basically the same thing, just fired from a different location. When you look at it from a land perspective you get a lot fewer people suggesting it. Would anyone here suggest it?

. I can only say how wonderful it is that moderators such as your good self are here to clamp down on such outrageous exaggerations in a not at all pernickety or anally retentive manner.
Play the ball, not the man. The crack about moderators has nothing to do with Swerve's post and is pretty antagonistic - surely you can see that? I don't have a vested interest in this debate (though it is interesting) but when I read things like the above I get a little wary of the direction such sentiments could be headed. You started off very well, don't ruin it by getting excited over a little comment.

That's probably good advice for everyone here at the moment. Be civilised.

The attached PDF shows what the new 155mm mount will look like. The footprint is very similar to the exisitng 4.5" system thus minimising the structural and below-deck changes required to existing T23/45 vessels.

This may not be the ideal option, but it's certainly a marked improvement on the 4.5.

The following quote reference Aster was taken from the below site. Makes for interesting reading reference the relative merits of different systems (full article)

DDG Type 45: Britain’s Shrinking Air Defense Fleet

June 28/10: MBDA Systems announces that its Aster-30 missiles have added Britain’s PAAMS-equipped “Longbow” barge to the roster of successful test firings using modified missiles.

“Over the last month…. The trials were conducted over a range of scenarios of steadily increasing complexity, culminating in a final trial featuring a salvo firing against a sea skimming target performing a high-g terminal manoeuvre. All the trials [by Italy, France, and the UK] were fully successful.”

June 3/10: HMS Dauntless is formally commissioned into Royal Navy service, at a ceremony in Portsmouth Naval Base. Neither HMS Daring, nor HMS Dauntless, is operational with its primary air defense weapon. UK MoD.

May 25/10 – June 1/10: Italy and France conduct test-firings of the Aster-30 missile from their destroyer-sized Horizon Class air defense frigates. The Andrea Doria fires a missile on May 25/10, while France Forbin fires a missile on June 1/10.

The test-firings are meant to ensure that the problems identified in Britian’s test firings from its Longbow test barge have been fixed, and are touted as successful by the French DGA. Renewed firings from the Longbow are expected to begin in a few weeks, leading at some point to actual firings from Type 45 destroyers. Mer et Marine [in French].

April 1/10: Portsmouth’s The News confirms that the PAAMS test failures have been traced back to a design flaw with the Aster missiles, which are being redesigned.

I sorry yes the AGS is was late! I agree with you view on it, I would like to see a Mk 8 based 155mm and I'm sure it would appeal to other navies.

In your last paragraphy are you suggesting the 57mm in the shore bombardment role? I know BAe make this claim, and I'm a big fan, but I think the shell weight must limit its effectiveness?

Its always about money and the allocation of scarce resources. The Counties where excellent sea boats but as value for money/effective ships they were very poor. Reflecting in some of them having very short lves. The T42 was the opposite a poor sea boat but was well armed and effective ship, it was a replacement of the T82. Had they been fitted with the 3D radar planned I believe they would have performed better, I think the Batch 2 ships befored far better in the Falklands.

Both Sea Dart and Sea Wolf underperformed in the Falklands because they their development was unfunded. But both developed in to excellent systems post war. At the end of the day all budgets have a limt and if you chose to spend money in one area you will not have to much money in others. I struggle with 28t Mk 8 was the right choice for a T42. I feel strongly that numbers are important, not to the exclusion of quality. The T26 has the potential to take us to a fleet of 14 ships whichI feel is not sufficient.

Thanks for the info.
Looks like a good way to upgrade gun capabilities on UK ships to me.

But hey, I am German. What do I know about navy stuff... :D

How would modern guns with active homing seekers fare against the air defense of modern warships?

I expect a dozen intelligent rounds fired in quick succession from maybe 40km would be a problem for anything short of a air warfare destroyer/frigate? Would probably a more sensible approach to give the Darings an additional anti-ship capability than bolting some Harpoons onto them. (Yeah I know that it's a bit like comparing apples to oranges)

But maybe stuff like SRBOC could foil the rounds more easy as there can't be that much room for an advanced seeker in such a round.
Thinking about this post overnight are you referring to a ship based NGS or a shore based gun, firing something like a Vulcano round.

If the former I would say it is unlikely because any potential aggressor ship is in the same space as if trying to launch a SSM. So vunerable to air attack its not going to get close enough.

However if the latter, you have a very good point. Again I would see control of the air would be key to giving the advantage to naval forces?

I did get me thinking about what is the most hostile enviroment you could realistically expect a naval assault force to face?

I thought more of ship vs ship engagements. RoEs, target location and restricted waters may very well lead to ships being some 40-60km away from each other when the shooting starts. Shooting a magazine of 14 active homing rounds so that they arrive together with the 2-4 harpoons one fired a bit earlier might become a big problem for the ship at the receiving end.

And one could shoot up a bunch of smaller boats which were spotted for example by an UAV. (IMHO better than the idea to kill them with something like NLOS...).

As for shore to ship fire. The Norwegians experimented a little bit with the PzH2000 in the coastal artillery role. They had good results when used against ships conducting shore bombardement or against amphibs unloading their troops (using impact, air burst and bomblet rounds). With active homing rounds mobile coastal artillery may become very lethal again. You don't even need dedicated guns for it. One can just use some batteries of SPHs.

I do think we should be seeking value for money and would have thought it prudent to build some (4) C2 spec ships first (governments do get the figures wrong) to replace the 22’s particularly as the 23’s are the last of the present generation warships to retire. I would see the C2 spec as pretty much identical to the C1 but fitted for and not with in some areas ie towed array as the 23’s are still around to cover that role.
As I understand it, the intention has long been that C1s will get the towed arrays from T23s, leaving T23s to perform the C2 role.

Sorry to hear of your sense of humor failure , just trying to lighten the mood of forum that maybe takes itself a tad too seriously sometimes . Your confident prediction that the T26 will turn out as quote : "a lot, lot, cheaper" than the T45 has been noted for future reference . :)

As for the serious crime of daring to call a 6850 tonne (full load) design a '7000 tonne' ship I'm guilty as charged . I can only say how wonderful it is that moderators such as your good self are here to clamp down on such outrageous exaggerations in a not at all pernickety or anally retentive manner .

.
I didn't moderate your post. I replied to it as a member of the forum. Any moderator responses should be clearly marked as such, e.g.
[Moderator]
This is a moderator message.
[/Moderator]

If there's no such indication, feel free to treat moderators with no more (or less) respect than any other members.

Now, back to normal service. Note: this is NOT in my role as moderator. For the purpose of this post, I am, as usual, in normal member mode.

You've been minimising on one side, & maximising on the other, for example using precisely defined standard displacement vs full load plus a bit. Personally, I find that an objectionable mode of debate. And as for 'sense of humour fail' - well, in my experience, that's usually the complaint of the sort of person who thinks any mention of 'surrender' & 'French' in the same sentence is hilarious.

The expected cost of T26 isn't my prediction. It's what the RN demands, & has every reason to expect. T26 has to be much cheaper than T45, or it'll be unaffordable. Price has been publicly stated to be a major factor in the design, & it should be far cheaper. It'll have much cheaper sensors (Artisan instead of SMART-L & Sampson), cheaper weapons, no massive PAAMS development cost to be split over only 6 ships (T45 would be mucb less than £1 billion each without that), smaller (yes, really!), etc., etc. Even the MoD will be hard-pressed to inflate the cost to anywhere near £1 billion in the circumstances.

I was looking at a small promotional clip on you-tube of Volcano and it had what looked like PzH2000 firing at armour and a ship based 127mm engaging FAC, being directed by UAVs. I think it highlights the need for the RN to get access to this sort of ammunition asap. It does beg the question are these more dangerous to ships or shore?

Another thought on your 2- 4 harpoon & 14 127/155mm rounds arriving in close succession. If you had an airburst 155mm round, what effect that would have on sensors, and the ships ability to continue a sustained defence?

A 155mm Vulcano round would make the 155mm gun argument even stronger obviously. Why go to 127mm as other navies move away.
IIRC 155mm Vulcano is 127mm saboted to 155mm, & is intended for use in land-based guns.

Other navies aren't moving away from 127mm. Germany considered & rejected such a more, & the USA is maybe doing it, with a hugely expensive, heavy, specialised gun with unique ammunition, for large ships only. I don't think that is significant. AFAIK, everyone else is content with 127mm.

So it doesn't count, unless it's on the scale of WW2? Okaaay...

1805, I think you've found your soul-mate!

Anyway, here's some news:

It seems the problem with Sea Viper/Aster has been solved, and Dauntless' trials of the system are back on track
More complete version at MBDA press releases

Note this:
Antoine Bouvier, Chief Executive Officer, said: “These successful firing trials demonstrate that MBDA has fully mastered the technical issue with the Aster strake that was uncovered last year on recent missile manufacturing."
So . . a strake problem, on recent missiles only. Sounds like a manufacturing problem, not design.

I expect that a fire mission with airbursts is going to result at least in a partially mission kill and maybe in a full mission kill. The sensor suites of modern ships should be highly vulnerable to the shrapnel. I expect that some of the bigger pieces will also be able to penetrate for example the launch tube of a harpoon or torpedo which might be nasty for the ship.

I have no idea how thick the top of a VLS cell is and if it can withstand shrapnel.

What about the bridge? Are the windows of modern warships hardened in any way? Shredding the bridge including the sailors on it would also be rather bad...

They would have to be at least slightly hardened to withstand the pressure of their gun firing at the very minimum wouldn't they? Not sure how protective it would be against shrapnel though.

As to the Type 22 batch one’s they were almost permanently close escort to the carriers but I would point out that all ships operational utility is dictated by its weapons fit and as we know later vessels do have a medium gun.
Although a welcome bolt on, Phalanx was never a potential for the Type 42 pre 1982 unless in the 1960's the naval architects could have persuaded the tight wad treasury to "build for but not with" (sounds familiar) to future proof the ship, however that was most unlikely, as common sense isnt a treasury strong point.

A ship would generally get a contemporay weapon, the MK 8 was designed in the late 1960's, first getting stuck on a ship in 1971, the RN getting it on Bristol in '73 (google is amazing!) and at 26tonnes was likely seen as a great improvement over the 40 tonnes of the earlier twin mount.

Type 42 was designed in the same period as the Mk8, Sheffield being ordered in 1968, commissioned in 1975, so a logical gun would have been the Mk8. I think the Oto 76 was also designed late 60's but only in the less impressive compact model, supposedly with issues such as falling apart at rapid fire rates (probs also marred the mk8 though) and a 76mm would have needed a new ammo type. I suppose that the choice facing the admiralty in the late 60's was use a UK system being designed, using the same ammo on a smaller mount or buy foreign. In that sense I dont think76mm would have been an option, not due to system weakness but on general balance of probabilities and just what we do eg national pride, industry needs even sometimes over common sense.

Phalanx was offered to the US Navy for evaulaution in 1973, by that stage 5 of the first batch of T42 had already been laid down on a cut down ,cramped design. Production of Phalnx didnt start until 1978 , the US would have got all the first systems and Coral Sea was the first shio to get it in 1980, by which time 11 of our Type 42 's had already been launched...too tight dimensions and weight, at a time of dire financial probs and imminent naval cuts (pre Falklands)

Now for the T42 to have been built "for" Phalanx would have required the type of foresight we rarely see. It would have been great to have prchased and early batch 1982 but that would never have been instead of of Mk8 or something else, the devlopment schedules just dont match.

If only the Treasury had agreed to an extra 1000 tonnes, the Type 42 could have reicieved that urgent bolt on, quite a good reminder in my opinion that building the T45 and Type 26 on the bigger side :relis probably wise, it gives so many more options CAMM, Sea Ram, some starstreak derivative etc.

I think I read Phalanx was considered as an urgent war purchase but the schedule was too tight, though it did arrive immediately after.
A final point forgotten is that the Mk8 in that period also fired a chaff round, so although not ideal, it added to the soft kill. Neither a Mk 8 or an OTO compact have much chance in downing an exocet, (maybe the Super Rapide that arrived much later>/ so I dont actually think a CO of a T42 on picket duty would have been too fussed what he had, phalanx yes, but He would be really lamenting not having Gannet AEW/Phanton./Sea Vixen (would it have still been viable had we kept the carriers??)/Harrier aloft giving him protection.

You are right though, the County's have a certain appeal others just dont, they look hard if you know what I mean.
