NASA's one-of-a-kind supersonic demonstrator, built at the Skunk Works in Palmdale to prove a sonic boom can be a thump. A 99-foot needle with no forward window: the pilot flies on a 4K camera. First flight October 28, 2025.

Fun fact

Its target boom is about as loud as a car door closing, roughly 16 times quieter than Concorde's.

How to spot one

A needle nose longer than the rest of the airplane, a tiny cockpit set far aft with no windscreen ahead of it, and a T-tail. NASA white with red and blue trim. Palmdale and Edwards only.

Sounds like
One GE F414, the Super Hornet's engine, in an airframe a third the weight. Sharp and rising, then gone.

One might be overhead right now.
