Intruder
Intruder was a naval electronic intelligence satellite for the National Reconnaissance Office (NRO).

Status: Operational 1990. First Launch: 1990-06-08. Last Launch: 2015-10-08. Number: 26 .

Compared to earlier satellites on this mission, the launch vehicle was changed from the Titan to the Atlas. Placed by two burns of the Atlas Centaur upper stage into an 1100 x 1100 km x 63 deg orbit. The design was apparently different from earlier generation NOSS satellites since only one companion satellite was deployed rather than two, in line with the lower payload capability of the Atlas. Prime contractor for the new satellites was believed to be Lockheed Martin Astronautics at Denver. The NRL probably continued to have a management and technical role in the program under overall NRO auspices.
