２１世纪美国不同军种空中力量将以发展和装备Ｆ－２２、ＪＳＦ和Ｆ／Ａ－１８Ｅ／Ｆ三种最新美国战术飞机为重点，其装备数量之大，预计耗资高达２０００亿美元。但布什新政府坚持要发展国家导弹防御系统和由于更加重视发展远程打击力量，打算重开Ｂ－２Ａ生产线，同时也需要巨额的国防经费投入，这么多的重头戏要唱，孰轻孰重，自然要费一番掂量？美国三种最新战术飞机计划能否顺利发展还是一个问号

However, as the new Bush administration insists on developing the national missile defense system and intends to reopen the B-2A production line by paying more attention to the development of long-range strike forces and also requires huge investment in defense funds, so many major events should be sung. How much? Whether the U.S. plan for the latest tactical aircraft can smoothly develop is still a question mark
