    Secret payload for the National Reconnaissance Office. The intended orbit was thought to be a "Molniya" elliptical 12-hour orbit with an inclination of 63 degrees. American data relay and signals intelligence satellites have used this orbit in the past, notably the Jumpseat series of 1971-1983. A secondary payload was later confirmed to be the first SBIRS-HEO (Space-based Infrared System) sensor. SBIRS was the successor to the DSP (Defence Support Program), which provided early warning of missile launches. Also carried the NASA/Los Alamos TWINS-A magnetospheric research payload


2008 March 13 - . 10:02 GMT - . Launch Site: Vandenberg. Launch Complex: Vandenberg SLC3E. LV Family: Atlas V. Launch Vehicle: Atlas V 411.
  • USA 200 - . Payload: Raven 5 / NROL-28. Nation: USA. Agency: Martin. Class: Surveillance. Type: ELINT. Spacecraft: Raven satellite. USAF Sat Cat: 32706 . COSPAR: 2008-010A. Apogee: 35,780 km (22,230 mi). Perigee: 1,112 km (690 mi). Inclination: 63.6000 deg. Period: 720.00 min.

    Classified National Reconnaisance Office satellite placed in a Molniya orbit; orbital parameters are estimated. Believed to be the second in a new series carrying combined signals intelligence and early warning payloads. Probable sensors included the SBIRS HEO-2 infrared missile early warning package and the NASA/Los Alamos TWINS-B magnetospheric research payload.
