Next Generation DDG and FFG thread (after 055, 052D, 054B)

[AndrewS]

If the Type 055B is a transitional model between the Type 055 and the next gen"national anti-missile warship," then we might see a VLS configuration similar to the Type 052D: mostly HT-1 VLS and a portion of the next-gen large-caliber HT-2 VLS.

This would allow for earlier sea trials and combat training of the HT-2 and next gen missile, and also ensure that the development achievements of the new missiles still can be transferred to older ships, just like the current YJ-20

This is why some people believe that the number of VLS units on the Type 055B may not increase or may even decrease—depending on how aggressively the HT-2 deployment ratio is implemented.

With the DDGX, the idea was for a bank of 32 VLS cells to be swappable with 12 CPS cells.
So they could have 64 Mk41 VLS cells plus 12 CPS cells.

If they can multi-pack HQ-9 missiles into a single HT-2 VLS cell, then there wouldn't need to be any need to compromise on the number of missiles?

Well that 20k tonne destroyer in that paper had a beam of 25 m so…

So the paper describes a ship with:

20k Tonnes Displacement
200m Length
25m Beam

---

So a 26m beam would be slightly larger.
To reach 32 knots (US aircraft carrier maximum speed?), such a ship would need about 80-90? MW for propulsion, based on the Kirov stats.

That would be possible with conventional propulsion, so they could build them pretty quickly.

---

So they could use two gas turbines such as the CGT-40 (44MW).
Ideally it would be an IEPS configuration, so they could have two 9MW diesels plus the two 44MW GTs, for a total of 106MW available.

That would leave about 30MW for an upgraded BMD radars, lasers, etc

I see a THAAD uses 2.1MW, so 4 such panels would mean 8.4MW for example.

---

I also wonder how the Chinese semi-submersible ship would fit into the fleet structure.

(It reminds me of the DDC (Corvette) concept with 32 VLS cells that the CSBA wrote about previously, where two destroyers were accompanied by four DDCs for example)

The Chinese ship does look like it is designed for high speed operations, and if I look at the fuel-consumption for 32 UVLS cells, such a Chinese DDC should have better [fuel consumption per UVLS cell] than the Type-052D or Type-055.

And if it is only ever designed to operate at periscope depth (20m), they could be built to surface warship standards.
At a depth of 20m, this should be enough for such a vessel to be undetectable/invulnerable to incoming surface missiles.

It could dispense with all the expensive sensors and defensive weapons, and literally just be the hull.
Such a ship should have a significantly lower [procurement cost per UVLS cell] compared to the Type-052D or Type-055.

So if such a Chinese semi-submersible DDC has a lower [procurement cost per UVLS cell] and [fuel consumption per UVLS cell], it makes sense to use DDCs as offboard VLS cells as much as possible.

This cost structure should also apply to a notional 20K tonne ship.

Judging by the hint, this warship is likely to be either a further development of the 055 DDG, or a successor to the 055 DDG. Perhaps some kind of (preliminary stage?) work is already underway by the looks of it?

In addition, there's something of note from sometime earlier this month (from the comment section of an unrelated post):

I believe that "Month M" likely means March (this year)?

I'm not sure if these guys are referring to the same ship as SOYO. Also, unlike SOYO, I'm not sure whether @一只在雪地上吃苹果的羊 is a dependable/reliable source, so kindly take his/her info with a pinch of salt.

Heh, so apparently Type 05X or next gen cruiser/large destroyer has allegedly a 26m beam which is far wider than any surface combatant PLAN has ever built, in fact it is probably going to be one of the widest modern combatants if true, with the only ship wider being the Kirov class nuclear cruisers.

He also seems surprisingly sure of this new ship so maybe he has heard some insider noise or something? I doubt it'll be from just reading a couple of papers etc. Has anyone has heard or seen someone else talk about this or some other info?

This does bring up the question...has it been confirmed that the new 071 hull is, in fact, a 071 hull?

What makes you think that hull is a DDG/CG?

If what SOYO has claimed about the dimension of the next-generation large DDG/CG is true:
- The 071 LPD would still be wider than the large DDG/CG by ~2 meters.
- Why would a DDG/CG need a large well deck and vehicle deck that take up more than half the length of the entire ship?
