Thanks for the complements on the picture.
yep, similar size. With the common VLS concept I have in mind, the various missiles don't have to fit into the same tubes (as on the US system), instead the VLS is just seen as an empty box into which modules of various missiles are 'plugged in'. The main limitation is the depth of the VLS box - I envisaged it above the ship's boat hanger I've drawn (the hole in the side of the boat). Therefore I can't imagine it being deep enough to carry Klub.

That's a hell of a lot of different systems to fit into a Frigate.

The 9K37 SAM is about 5.5 meters long and 400mm in diameter, comparred to the 91RE2 at 6.5 meters length and 533mm diameter. The 91RE2 is only 1 meter longer, but weights twice as much as the SAM at 1,300 kg.

Using the same ship model as the one you proposed, I'd go with the following arament load:
* UDAV-1 ASW MLRS system
* 8-cel Klub-N VLS (91RE2, 3M-54E1, or 3M-14E)
* 24-cel VLS launcher for SA-N-12 SAM & RPK-9 ASW rocket
* 2 x Kashtan CIWS system
* 1 x 76mm gun
* 1 x ASW Helicopter + hanger
* 1 x Mission module under aft deck

This design would make the ship fairly flexible. Under the aft helicopter deck, you'd have a removable mission module, and a choice of ASW warfare, special operations, mine-laying, or other types of equipments.

Beautiful, and may I add "sexy"? I think the conceal storage of the gun barrel is a good idea. Care to give some detailed view of the CIWS? Btw in your last post you said 16 YJ-62. Why change to 8?
The gun barrel idea I got from the Bofors Mk3 57mm gun fitted to the Swedish Visby class:

On the subject of Visby, this is the manufacturers concept for a frigate based on the technology:

Re My stealthised Type-730 CIWS, it would look something like this:

This consists of a faceted casing with angles of slope matchig those of the faceted hull.

I believe I have told you about the limitations of TAS in the operating environment of the 054A?
weren't you trashing 054A for not having TAS? Now, you are saying it shouldn't get TAS.
Singapore is well known for their meticulous requirements planning in the military procurement circle. If the RSN determined that the Formidable needed a bow sonar, it would have had one. It seems that the RSN determined that the VDS and the Heli could do the job.
Well, That's what I said about PLAN too. If PLAN choose to use bow and hull mounted sonar + Heli, let it be so. My point is that if it chooses to add Towed Array Sonar, it has indigenous TAS to add.
Finally, when we take into account the ship as a whole, with ASW capability and ASuW capability, it is pretty obvious that the Formidable has an advantage over the 054A.
where? you haven't shown anything. Your entire argument about ASuW lies in the SH-60, I've already shown that providing targetting information is not a problem for both ships. So, now it comes down to the missiles themselves.
Ironical, when all you have provided so far are assumptions. :rolleyes:
You rely on Internet documents for a Western system and I rely on pictures and posts of big shrimps from Chinese forum. Take your pic.
But you don't know yet if they have achieved the integration of the HQ-7 with a 'common VLS' don't you? You don't know that the VLS is for the SHtil or the HQ-16 don't you. You don't know a lot of things yet, yet you said that the 054A will have HQ-7s as part of its layered anti-air system?
- When SM-3 didn't come out yet, did people not assume that it will eventually go on AB? How is assuming HH-7 going on 054A in the future so far fetched? Besides, we got until 2009
- Have you heard about China purchasing any VLS shtil? We heard about China purchasing 2 sets of rif-m, no news about VLS shtil. We have 4 054As getting built right now, if they are using VLS shtil, we should have heard about 4 systems of VLS shtil by now.
The Saar V was not aware of the missile attack and took no measures to stop the missile. So its Barak and soft kill systems are not ineffective. They were just not operating at the time. Finally, there was a report of one of the ASM missiles locking onto the wrong target and hitting a cargo vessel. That could be the result of the significance of a small RCS despite no soft-kill measures like decoys or ECM being deployed.
your entire argument was about the advantage that formidable had over 054A due to its more stealth shaping, why are you bringing in other systems? If you want to bring in Air defense and soft kill systems, then you are pretty much admitting that the stealth shaping can't do all that much. The fact is that a really old version of C-802 (whose seeker is no where as advanced as that of C-802A, which is not as advanced as YJ-83) launched and given targetting information from a radar sitting on a truck hit a much more stealth target. Now, if 054A is to launch this, YJ-83 would have a more sophisticated seeker, a more advanced search radar, a huge radar dedicated to guide it against a more visible target.
Is the jamming aircraft going to be so near the missiles? Otherwise they are at a disadvantage since the Asters are MUCH closer to the ASMs than the jammers are. Also, can the jammers jam both the Aster's radar and the Herakles at the same time, which are operating on two different bands?
are you questioning the capability of EW planes? Besides, as I said, when facing an aircraft, a missile can get fooled much more easily than a shipborne illuminator.
You are pulling figures from your posterior.
I guess you haven't worked with predator + prey programming problems? You never want to intercept an incoming missile with just one missile.
Which is why your early assumption that all 4 FCRs can be brought to bear is wrong. At most 3 can be brought to bear against a single vector stream attack.
nope, directly in front or directly behind, there is an angle where all 4 can illuminate targets and both CIWS can also face off.
I thought we were comparing ships and not navies? Or do you sense that your position is untenable and hence this effort to bring in the rest of the PLAN into debate?
if you are in a system using some type of "Aegis type" defense like USN, you are obviously going to offer better air protection than a system not using one like Russian Navy. These types of systems are developed to handle saturated attack.

Hey Planeman, YJ-62 is actually much lighter and takes up much less space than Klub. YJ-63 is a whole different animal though.

I thrashed the 054A for having less ASW capability than the Formidable, as is evidently so. I didn;t trash it specifically for not having a TAS.

Well, That's what I said about PLAN too. If PLAN choose to use bow and hull mounted sonar + Heli, let it be so. My point is that if it chooses to add Towed Array Sonar, it has indigenous TAS to add.

Uh, China isn't exactly known in military procurement circles as a 'reference customer the way Singapore is. Besides, even if the indigenous TAS is fitted, do you think it can match the standards of western equivalents? I don't think so, but you are free to assume whatever you want, as you seem to do. :D

where? you haven't shown anything. Your entire argument about ASuW lies in the SH-60, I've already shown that providing targetting information is not a problem for both ships. So, now it comes down to the missiles themselves.

I have shown that the Formidable is more capable than the 054A by virtue of its ability to target and ID the enemy silently with its VDS, as well as its superior organic heli, the SH-60. I will elaborate later.

You rely on Internet documents for a Western system and I rely on pictures and posts of big shrimps from Chinese forum. Take your pic.

You rely on assumptions and rumours. They may be right, they may not be right. At the end of the day, you are just choosing the parts you'd like to be true. And yet you demand concrete proof from others. :rolleyes:

You working for the PLAN? Do you know all their purchases?

your entire argument was about the advantage that formidable had over 054A due to its more stealth shaping, why are you bringing in other systems? If you want to bring in Air defense and soft kill systems, then you are pretty much admitting that the stealth shaping can't do all that much.

Now, if 054A is to launch this, YJ-83 would have a more sophisticated seeker, a more advanced search radar, a huge radar dedicated to guide it against a more visible target.

The more you talk the less you show about how much you understand about the concept of 'stealth'. Stealth is not a stand alone measure. Stealth is part of a repertoire of measures, ALL working towards the end goal of improving survivability. Hard-kill, soft-kill, LO measures, they are all part of the survivability toolbox. Stealth does not negate the use of other measures, and hence there is no reason why stealth cannot be mentioned beside hard-kill and soft-kill measures, especially when stealth can affect the effectiveness of soft-kill measures.

Stealth improves survivability through two ways. One is by making the ship harder to find, and thus target. Another is by improving the effectiveness of its soft kill suite because they do not have to mimic a ship with a large RCS. As you should be able to see, these two advantages the Formidable has over the 054A give it an edge in Survivability with respect to ASuW. Another thing is that the Formidable is better able to target the enemy with its VDS and more capable heli, the SH-60. These advantages all taken together makes the Formidable a clear winner in ASuW.

are you questioning the capability of EW planes? Besides, as I said, when facing an aircraft, a missile can get fooled much more easily than a shipborne illuminator.

EW planes are much further away than the ASTER is to the ASM missiles. That decreases the EW effectiveness. In fact, when facing an aircraft, the aircraft is likely to have an easier time jamming the SARH seeker of the missile since the illuminator's radar waves have travelled a further distance than the Aster's.

I guess you haven't worked with predator + prey programming problems? You never want to intercept an incoming missile with just one missile.

All I said was that you were pulling figures from your posterior. Since they were from your S, any debate around them is like flies around whatever comes out from your bum.

nope, directly in front or directly behind, there is an angle where all 4 can illuminate targets and both CIWS can also face off.

In two specific angles only, yet you gave the impression that 4 FCRs could be used under all circumstances?

if you are in a system using some type of "Aegis type" defense like USN, you are obviously going to offer better air protection than a system not using one like Russian Navy. These types of systems are developed to handle saturated attack.

And what has that got to do with the Formidable? :eek:ff

Hey Planeman, YJ-62 is actually much lighter and takes up much less space than Klub. YJ-63 is a whole different animal though.
The stats suggest that:
YJ-62
Length: 6.1m (withou booster); 7m (with booster)
Diameter: N/A
Wingspan: N/A
Launch weight: 1,140kg (without booster); 1,350kg (with booster)

Klub (3M-54E)
Length (m) 8.220
Diameter (m) 0.533 (21' for torpedo tubes)
Weight (kg) 2,300

BUT, from the phot evidence of the 052Cs shows that the YJ-62 tubes are MUCH fatter than 21' (about that of the YJ-63 tubes) making them take up more space.
Please, Log in or Register to view URLs content!
Also, because they are mounted in incline launchers they take up more deck space, which has a greater effect on the number of weapons carried.

In my previous concept I envisaged a folding fin YJ-62 type of weapon making it take up the same amount of deck space as the YJ-63/Harpoon etc. A diagram of the weapons layout of my previous design:
4g9a8ba.jpg

As you can see the two quad YJ-62 launchers are mounted behind the bridge firing out over the side of the ship. Behind that the vertical launch modules are mounted, limited in depth by the boat stowage below.

A revised layout has a large missile deck within the ship, of similar dimensions to the vehicle deck on the fast ferries on which the hull is based. The missile deck is shown as having four quad YJ-62 launchers, two firing port and two starboard (you can only see two because the others are directly behind them, firing out the other side). This arrangement takes up a large amount of internal space but allows for the non-compact missile launchers seen on the 052C.
2hnc935.jpg

The missile deck could be cleared for alturnative weapons fits, or "commando" configuration.

In this version I have used the deck space saved by the elimination of the SSM launchers behind the bridge to relocate the vertical launch modules into a single bigger module in the centre of the ship.

The ship's launch would have to be relocated, so the boat shed under the hanger deck could be enlarged.

I have shown that the Formidable is more capable than the 054A by virtue of its ability to target and ID the enemy silently with its VDS, as well as its superior organic heli, the SH-60. I will elaborate later.

You can detect, track and target the enemy with VDS but ID is something else unless you can verify the ship's echo and noise signature by matching with a database. Silently is another thing; definitely you won't be silent because any form of sonar will be picked up.

Also to Planeman, great work, you must have spent a lot of time making this design and coming up with your specifications.

Not too sure what you're talking about here. Of course to ID an enemy vessel/sub its acoustic profile must have already been gathered and entered into an existing database. But to collect the target and ID of an enemy ship/vessel the VDS does NOT have to go active. Hence the Formidable remains undetected by the enemy.

What about using wire guided unmanned underwater vehicles (wire link also allows it to be powered by the ship's generators and be winched in even if you hotfoot it in the opposite direction at more knots than it can propel itself), with an active sonar of some sort, so that you can be 'loud' yet not give away your position? You could even use a UAV or rocket stage to about 10km before entering the water?

How thin are underwater power/control cables relative to the cables used by ATGWs?

You're talking about passive sonar then. If that is the case, you don't even need VDS to do that. Unlike radar, sonar being sound does not need to travel in a straight line by the way. Just so long the target has active sonar but what if it doesn't? Anyone can sit still and listen to each other for their propeller noises and the occasional pings.

For that matter the 054A if that's really a Bandstand up there, has Mineral ME2, which is also a passive radar complex that will also do the same above water, and you simply identify target through its radar emissions, obtain bearing and direction, then let the AshM do the rest.

WHAT?! It took you this long to realise that I was talking about the VDS being used passively?!

If that is the case, you don't even need VDS to do that. Unlike radar, sonar being sound does not need to travel in a straight line by the way. Just so long the target has active sonar but what if it doesn't? Anyone can sit still and listen to each other for their propeller noises and the occasional pings.

Err, I believe I have told explained convergence zones and stuff. You might want to find out more about that and how it limits bow sonars.

For that matter the 054A if that's really a Bandstand up there, has Mineral ME2, which is also a passive radar complex that will also do the same above water, and you simply identify target through its radar emissions, obtain bearing and direction, then let the AshM do the rest.

That depends on an opponent who has no idea of EMCON, right? Whereas with VDS, the Formidable doesn't have to rely on the opponent being stupid, neither does it have to give itself away with active emissions. Of course, with its own C Pearl-M ESM, it can like the 054A intercept the radar signals of an enemy emitting itself to oblivion.
