Aster has an active radar seeker. CAMM is also being developed with an active radar seeker.
The diameter of 180mm for Aster must be the missile, not the booster, which is much fatter, as the drawings show. “Diameter” always refers to missile body, not including fins. The booster fills the width of a Sylver cell, & if you take away the booster you have a short-range missile.
Indeed. BTW, the active radar seeker used on Mica is very closely related to that on Aster.
I agree with Obi here, the turbines and boilers probably went in but the installation of pipework and systems were left.
If the Turbines are anything like the ones fitted to RN ships like HMS Belfast in London they are actually fairly simple devices that are over engineered. I know on western steam turbines they casing can be pulled apart to replace the blade sections. The boilers are a bit more of a concern if they have been sitting getting rusty but China and more importantly Dailan shipyard has plenty of experience of Steam turbine propulsion and for that matter overhauling large Russian ships like the Komandarn Fedko class vessel Quinghaihu which was purchased as an uncomplete vessel.
plus, there probably is some commonality with the propulsion plants of the 4 Sovremenny’s.
A-10 or A-9?
Basically with some work Mica could be Quad-packed, how hard is it to make the fins fold is it a difficult job? The fins on ESSM fold i think but im not sure about that i dont know very much about it if im honest just done a quick google.
Some line drawings on FAS/Global defence suggest ESSM – like SM2 – has folding fins.
Pj we all know CAMM is Quad-packed that is not in Question, nice pic from the MBDA site though.
What people are discussing is if the VL Mica can be quad packed atm, in my opinion the answer is not currently. However it should be quad-packable as it is not a huge missile therefore it just needs someone to order it quadpacked in a launcher, the Greek FREMM drawings and specs out there show 24 A35 cells each with a single missile so that is where im drawing my answer from.
Furthermore the DCNS Sylver PDF shows only one missile per cell> http://www.dcnsgroup.com/files/pdf/Sylver.pdf it’s on page 2 btw. Im sure there was some information somewhere on the great interweb about the exact dimensions of each cell that i read. If anyone knows the exact dimension’s please post.
EDIT: After trawling through some crap what i’ve found is each cell is 22 inches or 55.88 cm square, seems a bit small but that’s from The Naval Institute guide to world naval weapon systems.
The diameter of Tactom is 51.8 mm, and it loads almost full bore so that 55.88cm would seem correct. Finspan for Mica was given as 480mm. So, there, no quadpacking unless fins fold (which they don’t currently).
With a 48cm finspan and a body of 16cm, each fin measures 16cm. A strake appears about half the size of the fin that, so for MICA ‘strakespan’ would be something like 32cm. If the VLU-cell inside dimension is 55.88 cm square, and you’ld take that 32 cm to be the diagonal of one of 4 imaginary squares inside that vlu-cell then the side of each of those imaginary cells is about 22.6cm. 2 x 22.6 < 55.88 . Hence, with folding fins, it would be possible to quad pack MICA.
Do the fins on ESSM fold?
Where will the Chinese have obtained the engines and boilers from, have they got a domestic scource, or will they have managed to purchase them from Russia or Ukraine? If they have been obtained domestically what steam conditions will it they have?
What do you think they put into the old Luda’s, 051B and 051C? That’s home built steam plants.
I still; based on the information on the refit/rebuild of Victorious, find it rather strange that the ship was built to the stage it was without having engines and boilers fitted?
No functional propulsion need not equate no engines and boilers fitted.
The ship is drydocked right?. If thats the case dont even bother going down through the flight deck – that way you will still have a couple of decks to cut through to get to the engineering spaces with the big stuff.
Do what most people do in dry dock and cut a hole in the side at the correct deck level and go in that way. Makes a great deal more sense to jack up and push across heavy boilers and turbines rather than try and drop them down into the hull. Remember when you are shifting large chunks of metal gravity is not your friend!
Of course!
Over 4000 tons. The first one cost about $750 million. The second & third of class were expected to cost about $600 million each. The Congressional Budget Office estimate of the cost of the rest of the programme (published July 2009) is $2.9bn – for five ships.
I think we need more than two or three C3, but that’s all we’d get at that price. This ship is much too big, & far, far too expensive. C3 is supposed to be cheap.. At that price, with only a single 57mm, I’d say it’s too expensive for C2, let alone C3.
More about the cost, & other problems. http://www.seapower-digital.com/seapower/200904/?pg=38#pg38 This reckons that the fourth ship is expected to cost $560-590mn.

MICA also has tail fins, & the strakes protrude more from the body. ESSM was specifically designed for quad-packing in a Mk41 cell, & the strakes are sized appropriately. MICA was designed without reference to the internal dimensions of Sylver.
I think this picture (MBDA official model, displayed at LAAD 2009) gives a better impression of MICA & its fins.
And here is a photo from MBDA, of an actual MICA on an aircraft, which confirms the accuracy of the model.
I suspect that some modifications would be needed to MICA before it could be quad-packed in Sylver, whether aerodynamic, or to make fins fold.
ESSM also has both strakes and (folding) fins, and the span of those fins is beyond that of the strakes as well, just as with MICA. Moreover, the missile body of ESSM has a wider diameter (20.8/25.4cm) than Mica (16m). ESSM overall is the bigger missile. Still, ESSM finspan does not exceed the 0.62m span of RIM7-M/P, the sleekest Sparrow version, while finspan for Mica is 48 cm. Problem I think is VL Mica fins don’t fold.
By comparison, finspan for RIM-156 Standard SM2 is 1.57 m!
Friedman’s Naval Institute guide to world naval weapons systems, 1997-1998 giveS the following for Aster 15:
missilebody 18cm x 2.6m, span 36cm
boosterbody 36cm x 1.6m (2.2m for Aster 30)
(by comparison, Aster 15 total length 4.2m, Aster 30 4.9m according the MBDA)
To be honest the reason why i dont think it can be quad-packed is because the Greek FREMM’s are said to carry 24 VL Mica and the launchers for them are beside the hangar so 24 missiles 24 cells. I could be wrong as i dont have much to go on really apart from some sketchy info.
That only means there hasn’t been a quad pack developed yet. Not that it’s impossible.
Swerve very good point the diameter will not include the fins for the Mica missiles and no they dont fold and im pretty sure of it, well the land based VL Mica certainly doesn’t and thats the same as the naval one.
Structurally, Mica is more like ESSM than VT1 and there is no problem quadpacking ESSM even though it too has strakes rather than fins.
VT1 has folding fins. AFAIK, MICA doesn’t. Makes a big difference.
Like Mica, ESSM has strakes…
VT1 doesn’t have strakes, only fins.
UPDATE:
it clearly showes that they have put some new stuff in those compartiments, possibly the electronics for the control tower and the radar.
Could you be a bit more precies about what and where? IMHO it only shows some areas painted and possibly closed off. Not much else (yet).
perhaps they gonna lower the parts for the engine in the hull piece by piece, and build the engine inside the engine room 😎
pls, this is the umpteenth time someone suggests that and it has been proven a dumb idea (why go through a superstructure located on one side of the shiup only when you have easier access accross the full width of the ship, through main deck and hangar?) including by drawings of internal layout..
nope.
general dynamics 30mm mk 46
Mk46 Mod 1 30mm Close-In Gun System:

– also used on LPD-17
– dual-axis stabilised 30 mm chain gun
– variable ROF up to 250 rounds a minute.
– can be operated locally at the gun turret or remotely in the combat information centre.
– system uses a forward-looking infrared sensor, a low light television camera and laser rangefinder with a closed-loop tracking system, to optimise accuracy against small, high-speed surface targets.
Yup Wanshan you are correct i have also read the PDF that’s on the website many times before to comapre it with the Mk.41 VLS. I’ve always thought that the A43 and Aster 15 are a waste of space as the are not much smaller than the A50 Aster 30 combo. VL Mica is an option for the Greek FREMM’s if i remember correctly and will use the A35 launcher for them. I now deduct that the Khareef class use a launcher built by MBDA and as far as i can gather the VL Mica cannot be quad packed.
I would like to see the CAMM missile used with the A35 in RN service as it’s a common control system with the larger launchers and would be ideal for the export market as i think Swerve pointed out.
From what I understand, Sylver A-35 through A50 fire Mica and can quad pack VT-1.
VT-1
Length: 2.89 m
Diameter: 0.15 m
Span: 0.54 m
Mica
Length: 3.1 m
Diameter: 0.16 m.
Span: 0.48 m
ESSM
Length 3.66 m
Diameter 0.203 cm to 0.254 cm body (0.254 m rocketmotor)
Span: ?
Juding from the above, it should be feasible to quad pack Mica (which does not mean it can already today).
