“联合攻击战斗机”(JSF)计划,是美国20世纪最后一个重大的军用飞机研制和采购项目。1996年美国国防部选定波音公司和洛克希德·马丁公司的方案进入方案演示验证阶段的决赛。两家公司先后各自制成了 JSF 的飞行验证机 X-32和 X-35,并分别于2000年9月18日和10月24日开始飞行试验。JSF 有三种型别:常规起落型(CTOL)、舰载型(CV)和短距起飞/垂直降落型(STOVL)。预计2001年完成验证机的对比试飞,胜者将获选进入工程研制阶段,为美国空军、海军、海军陆战队和英国皇家海军提供21世纪的新型战斗机。目前飞行试验还在继续,究竟鹿死谁手,尚待分晓。
The Joint Strike Fighter (JSF) program was the last major U.S. military aircraft development and procurement project in the United States in the 20th century. In 1996, the U.S. Department of Defense selected Boeing and Lockheed Martin to enter the final stage of the program demonstrations. The two companies each produced JSF flight verifier X-32 and X-35, and began flight tests on September 18 and October 24, 2000 respectively. There are three types of JSF: Conventional Undercarriage (CTOL), Shipborne (CV), and STOVL. The contractor is expected to complete the test flight in 2001. The winner will be selected for the project development phase, providing 21st-century fighter aircraft to the U.S. Air Force, Navy, Marine Corps and the Royal Navy. At present, the flight test is still going on.
