按美国空军观点,中国和俄罗斯的先进战斗机在2020年将完成,对抗五代机的反隐身技术届时也将实用化,中俄战斗机对F-22的有效探测距离将达47千米,战斗交换比可能会降低到3以下,这样的结果显然不能满足美国航空兵的优势观。发展更先进战斗机对美军不但是继续保持技术先进性的需要,也是装备发展中现实的问题。美国六代机的压制目标是与F-22同级的五代机。五代机的隐身是提高自 According to the US Air Force, advanced fighter jets from China and Russia will be completed in 2020 and the anti-stealth technology against the fifth generation will also be put into practical use. The effective detection range of the F-22 by China-Russia fighter planes will reach 47 km. The battle-exchange ratio May be reduced to below 3, such a result obviously can not meet the American aviation superiority concept. The development of more advanced fighter jets is not only the need for the U.S. military to continue to maintain its advanced technology, but also a reality in the development of equipment. The sixth generation of the United States to suppress the target is the same level with the F-22 Five generations of machines. Five generations of stealth is to improve self
