As part of the 60th anniversary of PLAAF, we have received a lot of new recently on the latest additions to PLAAF. Most of our information basically comes from 2 videos here and here.
A lot of interesting things were brought up here regarding J-10 and the 4th generation fighter jet project. If you don't already know, 3rd generation in China is 4th generation in the West and 4th generation in China is 5th generation in the West. In the videos, J-10 was mentioned as transforming China from cloning aircraft to developing its own aircraft. The emphasis was on finally being able to produce a home grown 3rd generation fighter for PLAAF. Some basic stats of J-10 included take-off distance of 350 m, having 11 hard points and payload of 6 tonnes. The pictures introducing J-10 to the August 1st flight demonstration team is as follows:
It had additional stats like length of 16.43 m, width of 9.75 m, height of 5.43 m, normal take-off weight of 12.4 ton (not really sure what the configuration is), maximum speed of mach 2.0 and operation ceiling of 18000 m. I think the maximum speed is probably higher than that from previous articles, but we probably will need to wait longer for complete information to come out.
In the videos, they said that J-10, J-11 and J-8 are the main force of PLAAF for the time being. 3rd generation fighter is already the main force of PLAAF. They also said that 4th generation fighter will make its first flight soon. After the first flight, it will begin test flight program. It can join service in 8 to 10 years. 4th generation fighter jet program have already been in development for a while, many parts have already achieved breakthrough like large turbofan engine, stealth technology and electronics. The goal of this plane is to reach the level of F-22. The videos say that J-10 is on par with the best of 3rd generation fighter jets, so China's 4th gen plane should also be expected to be on par with the best of 4th generation fighter jets world wide. The news of 4th generation fighter jets came from the deputy commander of PLAAF, so it should be considered pretty solid.
Below are photos from the TV shows showing possible look of the 4th generation fighter.
