美国空军已开始制造F-47型战斗机,这是其第一代下一代战斗机,计划于2028年首次飞行。 The U.S. Air Force has started manufacturing the F-47, its first next-generation fighter, with an initial flight planned for 2028. 由波音开发并建在一个扩大的圣路易斯设施内,这架隐形飞机强调先进的遥感、通信和低能可观测性。 Developed by Boeing and built at an expanded St. Louis facility, the stealth aircraft emphasizes advanced sensing, communication, and low observability. 虽然该方案在拜登政府下暂停,后来又恢复,但目前缺乏预期到2030年预期的预定NGAP发动机,并将使用临时发动机进行早期测试。 Although the program was paused under the Biden administration and later revived, it currently lacks its intended NGAP engine, expected by 2030, and will use interim engines for early testing. F-47的产量是战斗机发展的一个关键里程碑,尽管在发动机供应方面持续出现拖延。 The F-47's production marks a key milestone in fighter development, despite ongoing delays tied to engine availability.
