Since the "ideal PLAN FFG" armchair admiral thread is so popular, I thought I'd open one for DDG.

China has 2 major shipyards that build DDG's, Dalian Shipyard and Jiangnan Shipyard. Based on what we've seen with 051C vs. 052C, it'd appear that Dalian Shipyard tends to build ships with more imported Russian hardware, versus Jiangnan Shipyard tends to use domestically produced hardware.

In my hypothetical scenario, Dalian Shipyard is commissioned to build a new class of ASW DDG, while Jiangnan Shipyard will build ASW DDG's. I'll start with the ASW DDG.

Assumptions:

The ASW DDG will resemble the 051C with extended aft deck. The center section of the ship, where the SSM's go, will be replaced by a smooth superstructure housing 2 x 8-cel VLS system. The ship will weight approx. 6,000 - 8,000 tons.

Since this ship is being built in Dalian, we'll assume it uses many imported Russian systems. For accuracy, I used mostly systems listed in the Rosoboronexport Naval Systems Export Catalogue, located here:

ASW Systems

* 2 x 3S-14E (Kalibr-NKE) eight cel VLS for 91RTE2 ASW Missile, 3M-54TE super-sonic SSM, 3M-54TE1 subsonic SSM, and/or 3M-14TE LACM.
* RKPTZ-1E ASW system with 2 x KT-153E 10-barrel RL + auto-loader. The system can be armed with 111SG ASW rocket, 111SZ torpedo barrage rocket, or 111SO acoustic decoy rocket.
* 2 x 4 Paket-E/NK 324mm Anti-torpedo rockets
* ZARYA-ME sonar suite with underkeel, towed, & dipping sonar array
* Pallada or Anapa-ME combat swimmer detection sonar
* DT-65 anti-saboteur system with 2 x 10 barrel grenade launcher w/RG-55M underwater grenades
* PMK-2 ASW Mine system (? rounds)
* 2 ASW helicopters

Non-ASW Systems

* 76mm or 100mm Main Gun
* Shtil-1 ADMS with 24 x 9M317E SAM (arm launcher or 24-cel VLS)
* Kashtan ADGMS with 2 x 3R87-E combat modules + below-deck automatic reloader, with 64 x 3M311-1E SAM and 6,000 x 30mm rounds
* PK-10E decoy system with 2 x KT-216 sixteen-tube RL

===============

Originally, I was going to suggest installing 2x4 RPK-6 Vodopod (SS-N-16a) ASW Missile. But this system is not listed for export, and is quite old. I suspect the Russian Navy will retire it along with the SS-N-15 in near future. So I opted to stick with Klub-N system.

If 2 Kalibr-NKE VLS systems are too heavy, we can go with 1 Kalibr-NKE system + 6-cel Medvedka-VE (RPK-9) VLS system. If the Medvedka-VE is not ready, the older 2 x 4 retractable box launchers will work too. Also, if space and weight permit, we'd prefer to have 48-cel SA-N-12 VLS system.

I've left out other parts such as sensor suite and engines. It's assumed that the ship would be equipped with necessary sensors to operate the weapon systems, i.e. KMSUO fire-control for Shtil-1 ADMS and 3R-86-1E C&C for Kashtan ADGMS.

If this ASW ship will be used for data-link with shore-based ASW stations, we can also add AMGA-K system.

This ASW DDG follows my "triple layer" concept:

* ASW Detection:
Towed array sonar
Bow/hull mounted sonar
ASW helicopter dipping sonar

* ASW Attack
Helicopter-dropped torpedos
Klub-N ASW ASROC
111SG ASW rocket

* ASW Defense
Paket-E/NK anti-torpedo system
111SZ torpedo barrage rocket
111SO acoustic decoy rocket

* Missile defense:
Shtil SAM
Kashtan SAM
30mm CIWS gun

In addition, this ship will have passive ASW attack capability through PMK-2 ASW mine system that can either be remotely controlled, or programmed for automated detection/attack:

This ASW DDG is equipped with mostly imported Russian weapon suite as a stop-gap measure, since the PLAN does't have ASROC weapons ready. Let's call it CDX(ASW) for Chinese Destroyer X (ASW). I hope I've made it as realistic as possible with existing weapon systems that can be imported by the PRC.

For the air defense destroyer, it'd be equipped with mostly domestically made systems, which I'll get to later. We'll call that one CDX(ADS) for Chinese Destroyer X (Air Defense Ship).

Why not just make the DDG go nuclear... and I believe it's called a pump jet propulser?
Instead of 2 CIWS just give me 2 Metal Storm.....

I'm not a fan of nuclear, but I see your logic.

I think with metalstorm you could only fit say 4 rounds per barrel and maybe 20 barrels giving you just 80rds before you're out of ammo.

Using an electro-thermo-chemical howitzer as the main gun would give awesome range and muzzle velocity. I'm sure that's an advance that will happen but despite many people experimenting in the area, mainly for tank guns, we've yet to see anything operational.

I'm pretty sure you can fit more, on youtube there was one which they got 36 barrels... imagine if you jam that with 9 mm, a wall of bullets enough to rip through any missile.. or imagine if you jam it with exploding rounds with blow apart to give you smaller balls...

Is that the same a railgun?

CDX(ADS)

The CDX(ADS) ship will be built by Jiangnan Shipyard in Shanghai, and resemble an enlarged 052C with 7,000 - 8,000 ton displacement. The primary function is air-defense, with anti-ship and ASW as secondary.

The ship will have HQ-9 SAM's installed in the front, behind the 100mm gun. HQ-7 on top of the aft helicopter hanger, one Type 730 CIWS to each side. In the center of the ship, we'll install a superstructure to house 2x4 SSM's and a single Kalibr-NKE 8-cel VLS system for 91RE2 ASROC's. To the front & side we'll install 4 x 18-cel domestically made MLRS system for ASW rockets and decoys. Instead of the old 2x3 ASW torpedos, we'll use 2x4 Paket-E/NK anti-torpedo rockets for self-defense.

Araments
8 x 6-cel VLS HQ-9 (48 missiles)
1 x HQ-7 SAM with auto-reloader
2 x Type 730 CIWS
2 x 4-cel YJ-62 SSM
1 x Kalibr-NKE 8-cel VLS for 91RTE2 ASROC
4 x 18-barrel MLRS
1 x 100mm gun
ANAPA-ME underwater saboteur detection sonar w/2 x DT-65 grenade launchers
2 x 4 Paket-E/NK 324mm Anti-torpedo system
2 x Helicopters (1xASW, 1xAEW)

===========================================

Depending on the mission, the Kalibr-NKE VLs can be armed with ASROC, SSM, LACM, or a mix of the missile types. If weight doesn't allow the Kalibr-NKE system, then the RPK9 system can be subsituted.

For those unfamiliar with PAKET-E/NK system, please see here:

If a navalized version of the S-400 is avail, I'd obtain license production and upgrade the HQ-9 with S-400 SAM. But for now we'll stick with what's avail (HQ-9).

I'm just going to stick with ADS, since that's where I think PLAN is going
Currently, 052C is 7000 tonne in full load, so I'd hope CDX to be at least 8000 tonne in full load and maybe as much as 9000 tonne in full load.

I'm going for an attempt to reach the armament of flight II Arleigh burke.

ASW:
a bow mounted and a hull mounted sonar
MLRS
two triple 324 mm torpedoe tubes
towed array sonar

helicopter
hangar for 2 helicopters, 1 as ASW helicopter, the other as an AEW helicopter (ie: 1 ka-28 and 1 ka-31)

ASuW:
8 YJ-62 (or whatever the most powerful Ashm in PLAN is) or 16 YJ-83.
a surface search radar
Bandstand OTH radar + light bulb datalink

For AAW:
a common 72 cell VLS. Now, each cell would be able to hold 1 HH-9 improved, or 4 HH-7 or (2 to 4) HH-16.
1 76 mm main gun in the front
1 type 730 in front of hangar
2 type 730 on the sides like on 054A and 051C
those 4 huge radars
necessary illuminators
advanced ESM/ECM suite
"Aegis like" C3I system

might not reach this for a while,
an interim step from 052C
would be 8000 tonne at full load
room for 1 helicopter
no towed array sonar
64 cell VLS of HH-9
1 octuple launcher of HH-7 with auto-reloader and 24 missiles
100 mm main gun
2 type 730 CIWS

Well I think I would go to bit more realistic solution than some proposal made in this thread.

To take advantage of the already existing destroyer designs, this is my suugestion to ideal PLAN DDG at the moment:

Common hull. Why? Becouse china is becoming a superpower and superpowers need large navies with lots of hulls. Also superpowers doesen't need to settle for multipurpose hulls like smaller countries (multipurpose means that your ship scrach the surface of several fields but not good at any of those). But to ease the construction and designig, a common hull to field specialized shiptypes is quite good decision. In fact PLAN already have the 052B/C following this logic and as the hulls are acceptable size for any possiple need of fleet units, My suggestion is based around making the 052B/C to be "what they supposed to be".

First step, like with the ideal frigate is propulsion. I belive the current GODOG arragemt with only two gas turbines of LM2500 size is inadequate for ships of that size. I think that GOGAG arragment, like in the Alreigh Burkes is better so the ships would have four gas turbines. This will mean some rearragments in the midship section. The sole funnel in 052B/C will be transfered bit forward, just behind the main superstrcuture in the place of the engine ventilation box. A seccond funnel is placed on the place of the main mast (which will be positioned mid between the funnels and having far stronger precence). In effect the funnel layout is somewhat similar as in the 051B/C but the funnels are beamier. Both the airdefence and ASW ship would have the same type of arragments, only differnece being the mainmast which would hold the main air search radar in the ASw model.

Like in the ideal frigate, all the missile armament in both ships will be fitted in VLS. Thus we need a common VLS wich can launch all the missiles in PLAN inventory. In the ideal FFG thread I overruled this option, but in this thread we need to ressuerect it as it's the only way to make my proposal workable.
In the ASW version, the main armament will be the Klub-N system. It will be intergrated to the chinese VLS. The VLS will be able to handle the new chinese long range LACM when it comes operational (alongside the Land attack 3M-14E missile from the Klub-N family). Airdefence missile would be the HQ-16/SA-N-12. In the ASW ship, there would be two 32 missile VLS in the place of the front SA-N-7 in the 052B and in the rear between the douple hangar and the last funnel.

The Airdefence variants mainweapon will be the HQ-9 SAM. It would be intergrated to the Common VLS so that the russian style space-eating rotary launchers could be left in the past. Alongside the mainspears, YJ-62 (also in the VLS) would be fielded. So the Puma firecontrol radar for the ASW version would be replaced with the "what-ever-is-inside-the-052C-Bandstand-lookalike-dome" radar system. Both ships will have the Type-730A (with the TY-90 missiles incorporated like in the landbased test vehicle) CIWS in the same locations as their real life counterparts. Helicopter faciliates are enlargened in both ships to accomodate two helicopters.

Regardless of the size of the future chinese fleet, the ratio of these ships should be 1:2 (one airdefence variant per ASW ship).

Why does no one else try illustrating their ideas, a picture tells a thousand words.

Here's my evolved design:
aswddgxi1.jpg

(Note that the hull below the waterline is 'borrowed' from a picture of an Australian DDG I found on DefenceTalk).

My design is somewhat like the Kongo except that it has a far less bulky superstructure and a single fire control/search phased array on a rotating position much like on the Type 051C.

although it's not so obvious from this angle, the main feature is a very large helipad (about twice as long as on most DDGs) and a hanger capable of carrying 3 x Ka-28 Helix, Z-9s or Z-15s. 2 x Chinese designed rotory UAVs would also be carried.

Because of the extensive helicopter facilities, all the missiles (except the point defence ASW rocket torpedos) are carried forward of the bridge. Working fore to aft along the forward decks:
1 x 100mm gun with stealth measures
1 x 24 cell VLS for SS-N-27 Klub ASW and Anti-ship missiles (the raised section). LACMs versions could also be purchased. A typical fit is 12 anti-ship versions and 12 ASW versions.
1 x 48 cell S-400 SAM system with both "long" and "short" missiles.

2 x Type 730 CIWS with stealth casings complete the weapons fit.

A large bow mounted sonar and a towed system are also fitted.

Nice Planeman nice..You pics will soon be all over the Chinese military sites as the latest and greatest PLAN ships...and soon find their way back here...:D

With those two VLS cells where do you plan for the crew to sleep and eat? Those cells take up a lot of space.

What program do you use to draw those ships? Thanks!

Keep up the good work.
