美国一直把从20世纪50年代迄今喷气战斗机的发展划分为四代,而2006年初美国国防部和空军的一些官方文件中,时而也把 F-22和 F-35称为第五代战斗机,这是为了满足宣传上的需要,还是对喷气战斗机的发展进行了新的划分?本文对此谈了自己的观点。
The United States has been dividing the development of jet fighters from the 1950s up to the present into four generations. In some official documents of the U.S. Department of Defense and the Air Force in early 2006, the F-22s and F-35s were sometimes called fifth-generation fighters. Is it to meet the needs of publicity, or the development of jet fighter a new division? This article talked about their own point of view.
