The Walrus-class. Although it is a smaller boat, it is a semi-double hull meaning that compared to its submerged displacement it can carry relatively more fuel than a single hull submarine like the Collins [source Gabler; Submarine Design]. That confirms that Jane’s reports an equal range for the Walrus and the Collins. The endurance of both subs is set at 50 days. Another possibility could be the Kilo-class.
In response to the photo with 2 Collins from a few weeks ago here 2 pictures with 3 out of 4 Walrus-class subs at sea at once. The personnel shortages are almost solved!
The yard that produced these subs in the first half of the 1990s (RDM) no longer is in business. Of the remains of that yard, RDM submarines BV soldiered on for a while untill it went bankrupt in 2004. It was active only in trying to sell old Zwaardvis/Swordfish boats to Malaysia (similar to Taiwan’s Hai Lung) and marketing a new type called Moray. The design and engineering bureaus (Nevesbu, Verebus), still exist however.

While googling I came upon a rare gem: a detailed account of the Admiral Kuznetsov’s propulsion problems over its operational lifetime; from a Russian Admiral and former Chief of Staff.
Russian link:
http://www.zavtra.ru/cgi/veil/data/zavtra/07/735/52.htmlIt’s quite a revealing tale, I had no idea the carrier’s condition was that severe. All those proud flag-waving visits that were actually risky exercises that threatened another tragedy like the Kursk..
How OLD is this article, and when did the problems being discussed occur?
Well, I am not very sure about your concern, the number 79 fighter jet in the picture is a well documented Su-33 shipborne fighter.
What concern? (Do note the smiley š
No, the aft start position is where I marked it red to the left of the green line. You can see the exhaust shield there.
Indeed, that’s where there is an official third start position, complete with jet blast shields. But what would prevent the Chinese from adopting yet another position on deck, one without shielding. Just considering posibilities.
What about a line along which to locate helicopter spots (LHA role)?
Too long and wrong position, could be a deck marking.
Indeed looks like a deck marking, but passes between both forward aircraft launch positions to the middle of the ramp, it being closer to the left p[osition than to the right position. Might be a line for use of a long starting run (i.e. way to launch a more fully loaded Su-27/33 derivative, or a conventional aircraft e.g. some AEW/COD plane?).
From the latest pics the Varyag looks more complete than the Gorshkov/Vikramaditya! That says something about the speed and advancement of Chinese shipbuilding.
But even after all these years there’s still very little technical data available on it. For example
-How did the Chinese build the ship’s propulsion system? The Varyag was designed for steam propulsion with Russian KVG-series boilers. What did the Chinese substitute, given there’s no news of a Russian sale of boilers and steam turbines?
Chine builds naval steam plants, which are derivatives of originally russian designs, of which the Varyag plants are also developments. So chances are these plants are similar, to say the least.
As for no news of Russian sale of certain items, not everything aborad the russian ships is built in russia. In a lot of cases, Ukraine produced components and sometimes other eastern european countries as well. So, you might not have noticed a sale of such items if you were only monitoring Russia’s trade with China.
Gorshkov is being rebuilt by the country which originally owned her, & which has access to the manufacturers of her original equipment. She was operational for several years, & had a full fit of equipment. The original boilers & turbines were therefore available – though I’m not sure in what condition.
Varyag was bought as a hulk, with no propulsion. The Chinese did not have the option of refurbishing.
Given the length of time the Chinese have been working on Varyag, I don’t think we need worry about any difficulty in adapting her for different engines & boilers. They’ve had time to make any internal changes necessary, or make new boilers to fit.
No FUNCTIONAL propulsion, that’s all we know.
Look at the fighter on the left in below image, isnāt there clearly a āfull-span leading-edge slatsā as well? So itās also without āfoldableā wings according to your observation, but the plane on the left is a real Su-33 and we know itās with foldable wing.
Conclusion simply can’t be drawn in such a way.
I can’t find the tailhoook on the left plane …. (ok, maybe it has been lowered and is obscured from view, but still š
Interestingly, the French employ a company that flied Hawker Hunters for similar purposes.

Ticonderoga use the AN/SPY-1A/B
Arleigh Burke use the AN/SPY-1D
F100 use the AN/SPY-1D
Fridtjof Nansen use the AN/SPY-1F
THe F100 being significantly smaller than AB and Tico (NOT the radar)
Its a false economy in my opinion.
This applies at soooo many levels.
Not at all mate, I believe that all military training in every form should be handled by the military and not contracted out to corporate contractors who don’t really care about the country- just their profits.
Would you subscribe to that, but applied the the government as a whole (the military is just part of govenment). Contracting is quite common, since the 1980s.
I think the point is that the SPY1 radar, which is designed in the 70’s, is really that big and thus the structure of the ship has to be that big (or bulky) too to accommodate it. Be it the ship is designed in the late 70’s (Ticonderagas) or in the new millneimum (KDX-3). It is the same radar.
Although I’m not 100% sure, I thought the Spanish F100 has the same antennea. But this is clearly a lot smaller than the US ships. Besides, even the Burkes are a lot least chunky than the Ticos, for the same radars.
Getting back to9 the L-29’s, it seems the US is running out of money in a fast way if they are having to contract private firms to fulfill military training requirements.
The two L-29’s
N179EP
N5959LAre privately owned planes who rent out their services in a similar fashion to many other “Week End Warrior” companies over there in the US.
I know the USN are scratching around for $$$ but would this actually be an option that saves money? Most private ventures I know actually charge more. IMHO it would have been cheaper for the USN to use some of their T-45’s which better simulate the characteristics of modern day skimmer missiles, this evident by the RAAF using their Hawk Mk127’s in the same way during their regular excercises!
Rather than blaming them for spending more (too much) money, you are now blaming them for spending less (not enough) money?
Thanks, that was informative.
