Varyag back in Service?

[Pusser01]

Noting the pictures of the ex Varyag appatently being refurbished in the Photo Gallery, what are the chances of her entering service in the PLA-N?
Would she only be used as a basis to gain experience in carrier ops, or might the PLA-N spend the big bucks & get her to full operating status?
Any thoughts?

It doesn't make much sense to refurbish her for carrier landings if she is going to stay tied up to the pier. They could get the same benefit from a modified airstrip as they have been for years now. Either they are going to tow her out to sea for practice or they might try to put new engines in her and have their first carrier. It might not be cheaper than building a new one but it would certainly be faster.

[contedicavour]

Another way of looking at the Varyag issue is to think of what alternatives the PLAN has.
If the PLAN wants a new carrier, it would most likely be a clone of the Varyag because it would use Flankers, Helix and Russian technology.
So... if I were them I would fit engines and radars on the Varyag and start using those expensive navalized Flankers :confused:
Anyway, more than happy if they don't. Japan and Korea would answer back with carriers of their own and the whole Western Pacific would become a very dangerous area :(

:sniper :sniper Instead of bying navalised flankers, couldn't they just modify some of their own from the PLAAF or would the cost of that not be worth it? Also is it possible that they could use Q-5 Fantans as carrier borne mud-movers? finaly if they do commission the Varyag what specialized AAW or ASW warships does the PLAN have that would be able to protect the carrier?

The airframes of PLAAF fighters aren't strong enough for carrier ops. They're testing a primitive AEGIS type defense system, if operable would provide AAW but ASW is EXTREMELY lacking.

i thought that when china purchased this from ukraine that it was agreed it would not be used for military purposes wich is why the ukraine removed her power plant and electronic equipment it was supposed to be turned into a floating amuesment park but know its gaurded by heavy security,have they brokered a different deal with the ukraine or will china break the contract?

Most of the electronics, including the "Sky Watch" antanna, weren't installed; and the boilers were detubed prior to the ship being sold. The agreement with Ukraine was that the ship was sold to a private SOE (state-owned company) to serve as a casino; and in no way could serve as a mobile ship of any type.

What actually happened was as soon as the Varyag had cleared the Bosporus, the SOE went "bankrupt" and the Chinese gov't "forclosed" the ship.....so; technically they didn't legally break the business side of the arrangement.

As far as the military side; they are certainly making it somewhat operational in some regard. The photos show scaffolding on the island and welding on the main deck; that isn't routine hull maintenance. The PLAN will probably never formally recommission the ship to barely stay within the contract; until it's needed for combat. If taht should happen; all's fair in love & war as the saying goes and Ukraine has little to zero leverage against China.

If I had to put forth a guess, I'd say the Chinese want the ship not as a carrier at all, but as a makeshift LPH for amphibious ops. Given the gross unreliability of the Kiev/Kuznetzov proplusion plant (Kuznetzov has suffered five complete engine failures, and the Russians built a special ship that travels with her to provide steam when she's not actually in motion) I doubt the Chinese will retube the boilers and will instead install diesels. This would make for much reduced speed but would be perfect for using the ship as a "smart barge" for amphib ops.

The PLAN has built a Jeanne d'Arc type ship; the Shichang, to test the concept of this and is reportedly pleased.

:sniper

AFAIK the PLAN already has between 24 and 48 navalized Flankers ready.
Weaponry is comparable to SU-30, so these birds are good both at air-to-air combat and at air-to-surface combat with several standoff missiles of their own. Dangerous bunch indeed.
Although as Big-E points out, ASW is poor. A few Ka-28 helix helos won't be enough if a USN Improved Los Angeles gets the order to sink the Varyag with TLAMs or Harpoons.

Considering a refit Varyag would have a completely new set of engines I don't think the PLAN would put the same kind in after Russia's experience with this failure. This so called support ship you speak of, I have not seen it. Last time I saw the Kuznetzov she left a 3 mile oil slick but she was under her own steam.:confused: As I recall the Varyag was supposed to be nuclear wasn't she?

[Francois]

Not nuclear.
The Su-27s never could take off from the Kuz with more then a reco-pod or a single missile. No catapult, not enough power.

The support ship is/was nameless, hull # ENS-357. Soviet designation was Pr. 305 elektrostantsiye sudno ("ship supplying steam & electricity"); the NATO reporting name was "Tomba". Four were built in Poland at the same time the Kievs were building; three decom'ed in 1991 and the ENS-357 this spring. I'll be darned if I can find a picture but she looked like a typical 5000ton freighter; except she had a second funnel identical to the amidships one on the poop deck (it looked strange) and a "mack" mast on the foc'sle. In addition to her own powerplant; she had three extra diesels hooked up to generators and an electric boiler. She could provide an alongside carrier with direct electricity or steam.

The Kievs and Kuznetzov have rube goldberg engine rooms with eight boilers, four turbines, crosstied condensers, etc. It's just a doubled arrangement of the Moskva's propulsion layout, which makes no sense considering the problems they had with those two ships. All had engine fires; the last Kiev (Gorshkov) had fires in 1992, 1993, 1994, and 1996. The Kuznetzov has had no fires but lots of breakdowns. Here's a picture of the Moskva's engine room on fire. PHOTO: http://www.hazegray.org/navhist/carriers/images/russia/moskva-2.jpg

The two Kuznetzovs were never designed to be nuclear. You aren't off base though; the Soviets had two planned CVN classes: the Orel (about 80,000tons, planned for the late 1970s but cancelled to fund the Kievs) and the Ulyanovsk (76,000tons, laid down in 1988; she was about 90 days from being launched when the Nov '91 coup happened; the shipyard workers struck and never resumed work after the coup.) The hull was scrapped in 1994. Here's a pic of Ulyanovsk: PHOTO: http://www.fas.org/man/dod-101/sys/ship/row/rus/ulyanovsk-line.gif

No, the mk2s really are not navalized flankers, they are just flankers serving in PLANAF. It's not known whether China will buy su-27kub or get licensed production or develop its own with the help of the Russians. We will see. I'd like to see Varyag sailing out of the port on its power first.

In 1997 they tried to buy a sister ship to Chakri Narubet from the Bazan yards in Spain, they couldn't agree to a price. I'm surprised they haven't tried to buy Narubet itself; as the Thais barely ever sail her. Maybe there is a no-resell condition on the Thais' contract?

Supposedly they wanted the Clemenceau as well; the EU still has an arms embargo from Tienemmen so that went nowhere.

I'm assuming any future CV would have a ski jump. The Chinese are right now negotiating for the patent on the AL-31FN thrust-vecoring engine.

[long live usa]

im not sure if this is true or not but some speculated that when india offered to train crews for thailand's new carrier they were trying to prevent just that(the carrier being sold to china)?,but i doubt thailand would sell it now because it is intrested in a second carrier to protect its maritime zones in the andaman sea,although right now they lack the submarines for escort duty

Having done some reasearch on the capability of the Kuznetsov air wing, the 29th KIAP, wouldn't it make sense for the Chinese to lengthen the Kuznetsov in order to extend the take off runs for the aircraft or would they install catapult systems. The reason i ask is because the Su-33's and Su-25UBK are not able to take off with a full fuel load or even a heavy weapons load.:kar

If there going to go to all that trouble they might as well build another one. I think it would do PLAN a world of good just to get their naval aviation arm up and running buy refitting Varyag in her current config. It will help immensly to getting a better program started earlier when they start producing carriers domestically.

I know this is a little off topic, but i was wondering if the rumors that i have heard that have said that the russian federation said that they are working on a completly new design for two large fleet carrier size "aviation crusiers" one for the baltic sea fleet and one for the pacific fleet. The statement said that construction would begin in 2010 and be over around 2016. acording to some simple math i did, this is particullarily how long it would have taken them to build the UL'Yanovsk CVN. Also, with the Nikolayev ship yard now on Ukranian turf, would the Ukranians lease it to the russians or would the russians have to modify one of their other fleet bases in order to build these carriers, for example the baltic fleet base, which is where they built the Kiev's.:)

I wouldn't doubt them saying it as they have proposed some pretty lofty goals in the past and as it turns into today we find they go unrealized. They don't have the budget to get these new builds done on time. They spend all their money trying to operate obsolete Soviet era ships when they need to scrap them all and restructure the fleet. They have so many hulls that get started but end up running out of funding that by the time their completed their ready for the scrap yard.:(

The airframes of PLAAF fighters aren't strong enough for carrier ops. They're testing a primitive AEGIS type defense system, if operable would provide AAW but ASW is EXTREMELY lacking.

I'm wondering to what extent the supposedly Chinese AEGIS programme is not just an evolution of Russian designs. I would be surprised if China had right now the technology to field a system comparable to US AEGIS !
I agree Udaloys are big ASW ships (not really DDGs at all, unless we're just talking size and tonnage) with old technology.
Unless the post above talked about the Admiral Chabanenko which is an enlarged Udaloy with the AAW of the Sovremenny. A very good ship... for the early '90s ;)

well, China had the choice of Udaloy or Sovremenny in the 90s, and decided to choose Sovremenny. I personally think they should've taken Udaloy, but that's just me.

The Chinese "Aegis" program is probably an evolution of a lot of things. I wouldn't just limit it to one source.

Not sure about French involvement, could be that they got some help from Thales. As for the radar, it's definitely indigenous, but it might have gotten assistance from the kvant.

The CCS is a derivative of the first generation of TAVITAC.
Was sold before the TAM slaughter.
Can't be improved by chinese, because it is NOT possible to rev-eng.

The radar is definitively an Ukrainian design.
Very few countries can design such system entirely.

If it's a pre-TAM then it can't be very sophisticated and without the ability to rev-eng then it's garbage. The Ukranian radars deficiency with the lack of data capability of this system would be lucky to engage two targets at a time with any accuracy.:lol3

[Francois]

Usually, softwares are very difficult to rev.
Especially this type of soft.

The Ukrainians got ALL the experience from the Russians' mistakes.
I would hope it is far better then the first gen.
By contrario with their Northern neighbors, the Ukrainians did really quickly apply the Western design solutions (with the great help of Isreal I have to add).

I changed my mind lately, and subsequently, I call the 052C a potent threat, not to underestimate.
Again, against second tier navies around the South China Sea, it is perfect.
I would not put it in front of either SKN, SingN or MSDF, but a small navy like Philippines or else, yes.

Nobody knows how long China has been working on it and what kind of assistance China got from it. I'm sure China got Ukrainian assistance, but to what extent, nobody other than lab 14 would know. And yes, lab 14 developed it. I mean, has anyone ever even seen the kvant design to know how much lab 14 got out of it?

I haven't heard of any plans for new CV's; but they are planning two "assault cruisers" of the Ivan Gren (Project 11711) class.

The Russians are keen to develop a limited-but-rapid affordable power projection capability; kind of like the Brits, French, and Italians now have.

Very interesting, and probably worth a separate thread.
The Russians still have 3 Ivan Rogov and several Ropuchas. I doubt building new LST or LPDs should be their first priority. I would focus on preserving and modernizing some of the surviving Udaloy and Sovremenny...

Varyag never had its engines installed and has been left to rust for about a decade. It will never enter military service. China has repeatedly bought carriers from other nations, and EVERY time people have speculated and reported that the new acquisition was going to be put into PLAN service. It has never happened and its not going to happen with Varyag. The amount of work that would be required to get the totally alien and decaying ship back into service would probably exceeded the work required to build a whole new carrier.

And as for the Russian amphibious assault ships, that’s a real project but as yet the ships have not been funded. It might seem like an odd thing for Russia to buy, but think about it. How much naval combat goes on these days, vs. land combat? Russia is far more likely to make use of an amphibious expeditionary capability then it is to go toe to toe with enemy warships.
Amphibious ships are also not that expensive ton per ton since most of the ship is just empty space to house equipment and supplies, a USN Wasp class amphibious assault ship for example displaces about 40,000 tons, yet only costs as much as a 9000 ton Burke class destroyer.
