I heard that the United States has developed a drone with Mach 30 per hour. Is it true?/You don't say.

When launching a satellite, the rocket must reach the first cosmic speed, 7.9 kilometers per second. Mach 30 is equivalent to 10.2 km per second. If you hurry, you can reach the second cosmic speed of110.2 km per second. Such an airplane can fly directly out of the atmosphere. I know what you want to ask is X-37B, which is an unmanned orbital plane, but the rocket carrying it can reach the first cosmic speed, not itself.
