USA 250 - . Payload: NROL-67. Mass: 3,600 kg (7,900 lb). Nation: USA. Class: Surveillance. Type: SIGINT. Spacecraft: Mercury ELINT. USAF Sat Cat: 39652 . COSPAR: 2014-020A. Apogee: 35,790 km (22,230 mi). Perigee: 35,780 km (22,230 mi). Inclination: 0.00 deg. Period: 1,436.00 min. It appeared likely that the Centaur stage made three burns to deploy the USA 250 payload in geosynchronous orbit. The payload was suspected to be a large NRO signals intelligence satellite..
