SHARP 1 (USA-250) (NROL-67)

This series of satellites is likely a new series of geostationary ELINT/SIGINT satellites. Likely they consist of a large antenna and are three axis stabilized. Leaked NRO bugets documents identfy the SHARP (SIGINT High Altitude Replenishment Program) program, which could also be a possibility for this payload. These satellites might otherwise represent a next generation of the Orion satellites. Another possibility is a geostationary version of the Trumpet Follow-On series.
