This space plane 

is also known as the Orbital Test Vehicle.. It's completely autonomous and can even land on a runway without a human pilot.

The X-37B

has flown several highly classified payloads on long-duration missions.

For its first flight,

the X-37B launched on an Atlas V rocket from Cape Canaveral and it orbited the Earth for 224 days.

The U.S. Space Force has

a mini-fleet of two robotic X-37B space planes, which have been flying secret missions since 2010.

NASA's space shuttle, only it's much smaller and doesn't have any windows.
