American orbital plane completed a two-year secret mission

The experimental orbital plane X-37B Orbital Test Vehicle-4, which for more than 700 days was in space with a secret mission, landed at Cape Canaveral. This is reported by the official Twitter of the US Air Force.

Earlier in the Pentagon, it was reported that experiments were being prepared on the basis of the X-37B OTV-4 on the program for creating an ion engine and studying the changes in the properties of materials in space.

However, the full range of tasks of the American mini-shuttle is not disclosed. According to experts, the device can be a prototype of a space interceptor or reconnaissance aircraft.
