You know the Airforce has had those “secret” launches over the years and then there was that “rocket plane” flight that went of for what.. a year maybe before coming back down to Earth.

Too good to have not been tested. A Tianjin, China explosion in 2015 is rumored to have been a Rods of the Gods strike.
It is in the realm of actual secrets and speculation without the evidence of something like Israeli nukes.
