China's J-15 fighter superior to Russian Su-33
(People's Daily Online)
On Nov. 25, 2012, China's carrier-borne J-15 fighter jet has successfully undergone a series of sailing and technological tests on the Liaoning, China's first aircraft carrier, marking a great success of the carrier-borne fighter jet independently developed by China and a major breakthrough in the development of aircraft carrier technology.
The J-15 is equipped with two high-power engines and a brand-new system of high lift device, takeoff and landing device and arrester hook. Its wing can be folded up to both maintain the excellent combat capability and meet the special requirement of landing on the Liaoning. Featuring large combat radius, excellent maneuvering performance and high bombs carrying capacity, the J-15 has a fighting capability of full sea and full airspace.
Foreign media especially Russian media guessed that the J-15 is a copy of Russian Su-33 carrier-borne fighter jet because its appearance is similar to Su-33. In this regard, spokesman of the Ministry of National Defense of China Geng Yansheng said on Nov. 29, "The world military affairs have an objective law of development. Many weapons have the same design principle and some command and protection methods are also similar. Therefore, it at least is non-professional to conclude that China copied the aircraft carrier technology of other countries only by simply comparison.”
First, J-15 has an avionics more advanced than Su-33. Su-33 is equipped with old-fashioned ARINC429 discrete avionics system of one-way low-speed data bus, while J-15 adopts joint avionics system of bidirectional data bus.
TS-100, the Su-33's fire-control computer, has a computing speed of only 170,000 times per second, while the J-15's fire-control computer has an estimated computing speed of over several million times per second.
The J-15 owns a much more advanced radar system than the Su-33. Due to its backward avionics system, the Su-33 can only serve as interceptors, and is incapable of air-to-ground precision strike.
The J-15 adopts improved materials and production techniques, and thus has greater strength and lighter weight.
Finally, the J-15 is powered by home-made Taihang (WS-10) turbofan engine, which is more powerful than the Su-33's engine. Overall, the J-15 is superior to the Su-33, and is comparable to world-class carrier-based aircraft such as the United States' F-18 and France's Rafale.
I think they got the carrier launch system hooked up backwards.

Well, a copy built 30 years after original, with new materials and technology available has to be better than the original.
Looks like the child of an F-16 mated with an F-18.
The Russians themselves replaced their Su-33s with the Mig 29Ks so I don’t see what deal is :)
I realize the J15 and Mig29K are different classes, but considering they are both carrier craft, it would be interesting to compare them.
Well, Su-33 is a naval version of Su-27 which is a rough equivalent for F-15, Mig-29k is a carrier version of a Fulcrum which is in a class of F-16.
J15 is a reverse engeneered version (at least it’s airframe) of T10 - a Su-33 propotype Chicoms bought from Ukraine along with the carrier.
Russians replaced Su-33 with Migs in order to keep Mig company afloat in the first place. It also make sense to have a smaller aircraft for carrier operations. Su-33 on a carrier looks just like a cow on a small inflatable.
I would dare to say Chinese steel or aluminum, well hell any of their metals are so far below industry standards they are not much better than bamboo.
Never in my whole life have I ever seen superior Chines steel.
And like most Chines products it will work for only a short time, designed to fail premature to ensure customer purchasing in a repetitive fashion.
Exactly! I am quite surprised at the Chinese for trying to obfuscate what can be clearly seen. The 'indigenous' J-15 is a direct copy of the SU-33. It just happens to be that the J-15, built a couple of decades later, has newer avionics than the original.
BTW - I would still rather purchase an updated SU-33 than the J-15, even with the Chinese claims.
if i had to guess, i'd say the steel used in their military equipment is higher quality than what they export simply because they won't get SHOT for exporting inferior steel or anything else where it is a distinct possibility if they sell same to their military...
Here's a photo of the pilot:
