As for the 1st floor, it is really irritating to say that I have no AWACS. China's early-warning aircraft Airborne Police-2000 came out a few years ago, the 1st floor of the somewhat uninformed.
The Air Alert 2000 is improved on the basis of Il-76, the Air Alert 2000 uses phased-array radar technology, more advanced than the current U.S. and Russian products. Its service to fill the PLA has not been equipped with early warning aircraft blank its advanced radar technology, but also shocked the world. The early-warning aircraft using the Russian-made IL-76 for the carrier, but solid-state active phased array radar, the apparent proximity of the table, software, gallium arsenide microwave monolithic integrated circuits, high-speed data processing computers, data buses and interfaces are all designed and produced for China.
This is the introduction, but I think that even so our early warning aircraft will not be better than the United States, after all, we have only begun to develop, and suddenly from Russia to buy a transport aircraft a modification of the world is invincible that is not possible.
As for the specific performance of the American and Russian planes, the owner should look it up himself
