严重怀疑，试飞了那么久，没有一张照片和视频，这也保密的太好了吧

纯技术研究，这个2020开始试飞了？试飞5年了？有相关报告和视频资料吗？

英文维基百科Boeing F-47上头一段就写明： United States Air Force (USAF) officials said experimental tests have been flown since 2020
另外防长海格塞斯今天刚刚公开声明：“美国F-47战斗机的实验版本已秘密试飞近五年，将成为历史上最致命的战机”。
It’s worth noting at this point that, while the NGAD terminology is used in the podcast to refer to the crewed sixth-generation combat jet that will be at the center of NGAD, the program of that name is a much broader initiative, also including efforts focused on the development of advanced drones with high degrees of autonomy, as well as new jet engines, weapons, electronic warfare suites, sensors, networking ecosystems, battle management capabilities, and more.
The Defense & Aerospace Report, citing unnamed “sources involved in the [NGAD] program,” concludes that the existence of three NGAD demonstrators indicates that, at one point, three prime contractors or teams were involved and that this has since been whittled down to two.

中国已经有了。波音能造出来吗？2100年吗？

In the biggest development for U.S. Air Force tactical air power in more than two decades, Boeing has been announced as the winner of the service’s Next Generation Air Dominance (NGAD) ‘fighter’ initiative. As the centerpiece of the NGAD effort, the new crewed sixth-generation stealth combat jet, now designated the F-47, is set to change air combat forever, with the Air Force hoping to begin fielding it in the next decade.
美国发展F35这种廉价版的F22的原因是按照F22的发展成本，到2050年美国全部空军军费只够买一架当时最先进的战机。
这次马斯克折腾国防部，揭露出F22的发动机f119的推重比不是10.8，而是7，F35的发动机f135的推重比不是10-11，而是6.7，都低于中国涡扇15的10.2，相当于十年前的涡扇10的水平，维基已经更新了页面数据。这可以知道不论F22还是F35都不满足五代机的门槛（都不能超音速巡航）。
而中国刚刚官宣了可以达到音速16倍的新航空发动机。
美国在航空技术上已经严重落后了。F35立项时的目标是单价不能超过5千万美元，如今超过一亿，给美军最低的版本也是7500万。
而最近透露F135的叶片是中国提供，最近被中国停了。
中国去年禁止四种稀土出口美国，影响到美国90%的武器生产，美国不可能在十年内建立供应链。因此即使美国可以设计出新战机，也不可能大规模生产。
