This is an US military satellite of unknown purpose.
No details are known so far. It has been launched by an Atlas-5(531)² rocket with medium sized fairing.
A candidate object for this payload has been found by an amateur satellite observer in an ~11000 km MEO orbit with 58.5° inclination. There are no precedents for a satellite in this kind of orbit.
Note: The NROL designations refer to the launch, not to the payload.
