美国试飞过三架六代机原型机吗? 没有照片,没有视频佐证。 一切都是秘密,都是据说。

Additionally, the US is believed to have been the first to fly a sixth-generation demonstrator in 2020. Now at least three NGAD demonstrators have flown (likely from Boeing, Lockheed Martin, and Northrop Grumman). These have been flown in secret and there are no publically available images for them.
