1. radar.
The radar of F35 is old and small, and has developed into an electronic warfare platform, so the detection distance to the air is only180km. We have given Xiaolong KJL7A 170km, from which we have deduced J- 10C220 and J- 16280km, and the larger and more advanced J-20 radar is 300km. The new generation radar has been optimized to detect and identify tiny targets such as stealth fighters and cruise missiles, and it also has a strong detection capability for the fourth generation aircraft. The head-on detection distance of F22 is about 120km, and that of F35 is 150km. At the same time, EODAS photoelectric system. There is also a J-20.
F35 radar, the forward detection range of J-20 is only 90km, which is 120km after improvement. If you want to go further, you can only change to a new generation of airborne radar. Therefore, the J-20 against F35 can be discovered by the enemy first, and then the enemy can seize the favorable height and position and fire first.
2. invisibility.
They are stealth aircraft, and the RCS is two or three times larger, and it doesn't matter if it is two or three times smaller. The RCS of the former J-20 will be smaller and the side will be similar. The RCS of the rear J-20 is indeed much larger. F-35 widely uses the most advanced aerodynamic design and radar absorbing materials, which is more effective and easier to maintain than F-22. The design of the nose and cockpit of the J-20 is similar to that of the American F-22, and its frontal stealth capability is excellent. However, due to the canard design and the vector engine without stealth optimization, the radar cross section of the side and tail of the J-20 is larger, and it is more likely to be discovered by radar.
3. Mobility and ammunition.
歼 20' s high thrust-to-weight ratio+super patrol+super maneuver+lightning 10E+ head aiming. In the battle, the J-20 can almost form an advantage close to the generation difference, and the F35 can only be dealt with by network-centric warfare and electronic interference.
4. Electronic warfare and network-centric warfare.
F35' s electronic warfare and network-centric warfare capabilities are beyond doubt. It is certainly effective for the pulse Doppler radar and data link of the third generation aircraft, but the J-20 is equipped with a new generation of large-size, high-power and digital array AESA, and the huge nose and fuselage are also equipped with a new generation of electronic warfare and network-centric warfare equipment. Comprehensive electronic warfare and network centric warfare capabilities should be better than the old F22, only slightly worse than the latest Sharp F35 in the United States. But this small difference is not intergenerational, nor is it decisive.
The cost of the J-20 is much lower than that of the F-35.
In terms of cost, there are three models of the F-35, the cheapest of which is the F-35A. The "cheap" here is ridiculous. In order to make the price look less high, Loma creatively invented a new pricing method, claiming that the unit price of the F-35A is 98 million dollars, without an engine. Nevertheless, the F-35 project has already spent 65,438+0,638.
The price of the J-20 is much lower than that of the F-35. The price of weapons made in China is usually one-fifth to one-third that of similar weapons in the United States, and the purchase price of its troops is generally 5% on the basis of the manufacturer's cost, which is a special treatment that the US military is also very envious of. Take the F-22 fighter as an example, its price is $654.38+50 million, so the price of the J-20 is about $30-50 million. Considering the high cost of the fifth-generation aircraft project, the final price is expected to be around 60 million US dollars. Even so, it is far lower than that of American fighters. The unit price of F-35A purchased by Israel is $65.438+$67 million.
See how to define quantity theory or quality theory.
Each has its own advantages and advantages. My evaluation is that j20 and f35 are basically the same.
