Secret hypersonic aircraft and spacecraft are unlikely. Those put out so much energy that they're just impossible to hide.

I've heard of it but I doubt it actually exists. There's no real mission for it that can't be done better by satellites or low-observable drones.

They kept a Mach 3 plane secret for a long time…

No they really didn't. The Soviets, North Vietnamese, and North Koreans all detected and tracked the A-12 / SR-71 planes during operational missions. They didn't know all the details, but the existence wasn't at all a secret to our adversaries.

It was secret from the public. Which means there are certainly military projects right now that are also secret from us, even if Russia knows
