Don't get me wrong, I have a lot of respect for the Sigma platform (Love the compact Sigma also), that by the way can expand into a lot of sizes and be customized a lot (Aster for example), but here we are talking about the Vietnamese 9814 Sigma. My original statements are based in regards to the Vietnamese Sigma and Vietnamese Gepard. You are taking things out of context.
They are just as useless against a chinese fleet as a p28 - even a modified one - would be. Which doesn't mean they are useless per se. THere is a cost-effectiveness question here.
What are you talking about with P
roject 20350? How the capabilities of a 4500 ton frigate have anything to do with what I said that the Gepard can only house one VLS? The Gepard is a 2200 ton ship. The 20350 is double the size.
Typo, I referred to a variant of 20380 (Steregushy, 2200 ton fld) not 22350 (Gorshkov, 4500 ton fld). The variant is 20385, and has additional vls for Redut.
The Palma/Palash on the Gepard (rear end) are in very particularly limited, very tight spots, is very questionable that can put a VLS there, all the VLS systems in Russian ships are in areas where they are taking a lot of space.
See pic above. The 15km range 9M100 missile can be quad packed and is relatively short so, given the number of cells, I expect the 40km 9M96 to be used also (e.g. a 8+14 or 16+12). If so, you'ld need 4.75 minimum depth (1.5-2 decks). Less if it is only 9M100 (2.5m, about 1 deck). There is room taken up below Palma/Palash on Gepard that can be used.

Yes, I know there is no customized P28 except the proposed version for Philippines but we are talking about what the article mentions, assuming that the article is true, which we don't know yet, then there is a project for a customized P28 for Vietnam that seems pretty good.
I agree. Still, since warship cost in predominantly a factor of systems on board, rather than the actual ship, why not a bigger unit so as to make sure there is ample space and electrical power to support the weapons in question with the best possible radar fit and a more than adequate number of missiles (esp. SAMs) while retaining e.g. RBUs.
Everything that I've read about the Sigma of those sizes such as the ones for Indonesia, Algeria, etc does not include anything about special noise reduction measures such as done in P28. If that were to be the case, then it would be mentioned as a feature, but never heard of it. This has nothing to do with the capabilities of Damen, of course Damen is capable of doing it, they also make advance destroyers, but again, we are talking about the Vietnamese Sigma 9814 for Vietnam. You are taking my points out of context if you compare to other Sigma version or about Damen capabilities.

UNder General Information you find:
Standards: Naval / Commercial, naval intact / damaged stability, noise reduced, moderate shock
Same with all other Sigma family members
By comparison, with 6000 ton LCF (Zeven Provincien class) it says:
Vulnerability: Full NBC citadel, Shock & blast protection, Extensive Damage Control, redundancy and separation, Blast and fragment protection, Signature reduction: RCS, URN, IR, Magnetic, Electric
By comparison, with the Holland class OPV it says:
Standards: Naval / Commercial, naval stability
RELIABLE PERFORMANCE
The first SIGMA corvette built exceeded all performance predictions. Notable were the very low noise and vibration characteristics up to maximum speed. The second corvette confirmed the performance of the first one.

I don't think there is anything that compares to Barak 8 (including Aster).
CAMM - while clearly a different system - gives it a run for its money
Just because something is part of the S-300 / 400 does not make it mighty just because of that.
The missiles of Redut are part of S-350 (which is a S-300
replacement) and also used in S-400. While I do not claim Redut to be a magic bullet (which is what some here would have you believe about Barak-8), you cannot dismiss these missiles as ineffective off hand.
What makes the S-300 / 400 a very special system is the long range missiles, the ones with 250 and 400 km range, those are the ones that are very special, the short range missiles are nothing special, that's why a S-300 / 400 battery always operates protected by a Pantzir battery. If it were to include Barak 8 as a short / medium range missile (500 m to 90 km range, yes I said 500 m, do you know any other system like that?) it would not need a Pantzir system.
I suggest you read up on S-350 and S-400. S-400 only employs the long range 9M96 missile i.e. it has no organic point defence missile. S-350 (Naval version: Redut) on the other hand has both the long range 9M96 and point defence 9M100 and would not need Pantsir for battery protection at all.
You forgot that the article specifically mentioned 32 Barak 8 missiles (not 16 as you mentioned). That already give you some clues about how extensive the customization of the P28 for VN is since the standard P28 will carry only 16 Barak 8.
I would not be surprised at all if it is also stretched (if needed) in order to house a Brahmos VLS where the RBU-6000s are located now.
Interesting, since the original P28 was to get 2x8 Barak-1, not 2x 2x8. Remember, the Godavari's got just 3x8 and Viraat just 2x8. Only P15 and Rajput classes of destroyer were refitted with 2x 2x8, as were new major ships like p17 and p15A. Good luck shoehorning in 2x16 on P28.
