Lol... But why would it? There's only 3 of these things and they've only launched 7 missions. They're also only 29 feet long. And are payload hogs on their launch vehicles.

It's about 500 times easier to just piggy back 20 micro-sats on the next atlas or falcon.

The whole "x37 is a spy program" was literally started by speculation in an opinion piece with zero evidence. It being a visible and public program mean it's absolutely almost certainly not an active spy program. Especially combined with it's mission profiles.
