The official word has been spoken. I'm curious as to what the members of this forum think about this little tidbit;



Is this the truth or just a ploy to keep us China watchers including the US DoD in the dark on the capabilities of this ship? And if there is no catapult what happened to China's research and development on catapults,both steam and EMAL, in general? Was the reported development of catapults a smokescreen or just fan boi dreams?

We know that the Chinese cat much be nearly ready for prime time because we saw a photo of a J-15 nose gear designed for its use.
Forty years ago I learned in a lecture by Professor Kohlman about the advantage of using a ski ramp for take off, not just for Harriers, the British mini-flattops were then being built, but also for aircraft without thrust vectoring. I knew already about linear motors so I could have invented the cat in a ski ramp if I had thought of it. The Chinese were thinking of it more than a quarter of a century ago and are likely to have been developing such a cat at least since they thought about buying Varyag in the early nineties. I would think we would have heard more about the development of China's cat if they were just imitating US work.
So if 001A has a cat in the ski ramp the official was not lying when he said they were using the ski ramp.

Here is the for people who poo poo the idea of catapult on Chinese carrier. They decide not too because they thought it is easier to integrate the J 15 seamlessly without any further training and not for lack of technology

China’s first home-made aircraft carrier will be a copy of a Soviet-era vessel with some refinements, with the navy rushing to ramp up its combat capacity as maritime tensions rise in the region, according to analysts.

The defence ministry confirmed on Wednesday that the country’s second aircraft carrier was under construction in the port of Dalian.

It would be conventionally powered, with a standard displacement of 50,000 tonnes, and have a ski-jump flight deck, features that are very similar to those of the Liaoning, a Soviet-made vessel sold to China in 1998.

The new warship will be slightly lighter than the Liaoning but have more space for fighter jets, according to Ifeng.com, an online news arm of Hong Kong-based Phoenix TV.

J-15 fighter jet pilots and crew were training on the Liaoning and be able to transition seamlessly to the new carrier, the report said.

Retired major general Xu Guangyu said military assessments indicated that China was ready and able to develop a catapult launch system but top brass had opted for a more dated ski-jump take-off because it would allow for a smoother transition for the J-15.

PLA Daily quoted Zhang Junshe, a researcher at the PLA’s Naval Military Academic Research Institute, as saying that the country would need at least three aircraft carriers to meet its demands for naval patrols, training and maintenance.

EMALS need a lot of electrical energy in a very short time - and you don't have this at conventional powered ships

You put extra steam boilers for conventional steam-cat carriers and extra diesel generators for em-cat conventional carriers. In second case, a IEP propulsion should eliminate dead weight of the extra diesel generators.

That's possible but then the rate of fuel consumption would go up for the extra power needed? Do EMALS consume more power vs steam cats?
