Posted today at the Top.81-Forum, this is one of the first two serial J-15s in full PLANAF markings. Identified were so far the numbers 102 and 103 (as shown).

Hmmm ... not really sure, we know the prototypes 551-556 + the J-15S prototype and now confirmed (rep.) the serials numbered 100-105.

By the way ... the PLANAF goes Topgun-style ... ;)

Whats the current status of the J-15 fleet? Google Earth tells me that the carrier air wing facility on the coast of the Bohai sea is complete and has been for sometime, there appear to be 24 shelters for J-15 type aircraft and then three much larger hangars suggesting that at least 24 aircraft will constitute the initial production batch?

Sorry that I've missed that post !

So far by numbers 11 aircraft are conformed (100-110) ... and it is expected when the Liaoning will finally came home these serial aircraft will take part in their first cruise ...

These two are from today.

IMO this could well be a serial J-15S !?! :confused:

If you compare with the original prototype (at least the first images), then it had originally always green tails, whereas this on is painted in the same standard yellow primer like all serial J-11/-16.

I would be shocked if the carrier they're currently building didn't have catapults. Thought I'd read they intend it to be another STOBAR carrier.

Some serious talk I've seen is that it's a STOBAR but might/will have a single waist catapult. Would allow PLAN to begin training toward a CATOBAR future without risking too much from a sudden changeover.

The carrier they're currently building almost definitely won't have catapults.

No, it's doubtful that it'll have a waist catapult -- it'll be a pure ski jump/STOBAR carrier

001A is meant to be a relatively low risk carrier with only minor improvements over 001 (Liaoning)

One crash won't change a single thing, let alone cause China to cancel it's blue-water/carrier plans.

Hi Deino, thanks for posting those images. What are the chances that 002 will be the next laid down in the dry-dock at Dalian that currently houses 001A and was previously used for Varyag/Lioaning?

To admit I don't think so. Following the most reliable reports and rumours, no. 002 will not be laid down at Dalian, but at Jingnan. However there are recently reports that before 002 will be laid down, another 001-derivate - some say 001B - will be build at Dalian.

But I think only time will tell.

Recent operational images of J-15 show centerline IFR pod testing. Looks like the same UPAZ-1 pod as seen on this test J-15 '556'.

First clear image of a J-15T prototype at the catapult track released

As noted in late January (Modern Chinese Warplanes-update 31) the PLANAF was conducting catapult launch tests off its facility at Huangdicun.

Now – reportedly taken from a lecture of Professor Ma Weiming - the main leader of the Chinese PLAN EMALS project at the Chinese Academy of Engineering – the first clearer image was released showing the J-15T prototype (no. 1x1) reportedly at the EMALS-catapult position.

If China decides to adopt the EMALS approach for their carrier operations the question being raised is how do they power the catapults? American carriers are nuclear powered. This means plenty of electrical power for the cats. China does not have that luxury of excessive electrical power. So unless the Chinese / PLAN has another method they will be at a disadvantage trying to use EMAL cats on their future carrier. Check this out:

"EMALS was designed for and into the Ford-class carrier. A proposal to retrofit it into Nimitz-class carriers was scuttled because EMALS needed more electrical power than provided by the carriers' two Westinghouse nuclear reactors. John Schank said, "The biggest problems facing the Nimitz class are the limited electrical power generation capability and the upgrade-driven increase in ship weight and erosion of the center-of-gravity margin needed to maintain ship stability." Therefore, the newer Ford-class carriers were equipped with power plants that produce more electricity than the ship currently needs. This allows unforeseen technological advances to be implemented later."

Does this mean that the later classes of PLAN carriers will be nuclear powered? That would be a big step over where the Chinese are now. As they say: Its more to it than talk!

Electrical power generation isn't a hard problem. The issue with the old carriers wasn't that the reactors didn't produce enough thermal power, but that they weren't set up to turn enough of that into electricity. The Fords have much larger Ship Service Turbogenerators that can easily provide the electricity but they aren't much more powerful in raw terms.

For a conventional ship, all-electric propulsion or dedicated generators would provide plenty of power.

When the Brits were looking at switching the QEII to catapults, there were lots of problems but i don't think getting enough electricity was one of them.

Weight? To generate that kind of power you will pay a penalty in weight for the dedicated generators on the ship.

The figure I've seen is roughly 6.5 MW to recharge one EMALS catapult at normal launch cadence. That's not a huge genset if you wanted a dedicated unit. And if you went for integrated all-electric propulsion, tapping that much power out of ship main propulsion power would be a very small speed penalty.

So my question is where did the United States navy go wrong with the EMALS system on the Ford? Is it the interconnected systems of the cats to where to service a problem with one EMALS cat all EMALS cats have to be taken off line? Is it a design issue or something else?
Or is it really a problem at all?

It's the very first shipboard installation an a couple of years from being operational. No surprise it has bugs.

Basically the USN got their timing wrong, the design and testing of EMALs wasn't in line with the CVN-21 build. To be honest they should have really built another Reagan instead of Ford to allow the new hardware to be fully tested and ready for operational duty.
Ideally they should have had a carrier spare, either the Kennedy or a Nimitz prior to refuelling to do a test of the EMALs at sea, possibly using a separate generation plant in part of the Hanger but they have been doing more with less leaving no spare capacity or funding for too long and as a result they didn't have the spare capacity and took some calculated risks.

As for the PLAN we will have to wait and see, we know they are testing EMALs, but we also know their second carrier is just a refined Kuznetsov so we have no idea as yet about the carrier design they are planning to use EMALS on.

That is, to my understanding, correct. There is plenty of existing generating capacity and space to add considerably more. You don't need nuclear reactors for EMALS. I am half expecting the Chinese to produce Varyag sized carrier with 2-3 EMALS catapults and GT propulsion/generation in an integrated electrical configuration.

the latest rumours from earlier this year suggest 002 will be a bit bigger than varyag, something like 75,000 tons full, with up to three catapults.


In any case, the EM catapults that Ma has been working on seem to have been well received.
