2006-057A
The first United Launch Alliance launch. NROL-21 is thought to be an LMSC experimental prototype for the FIA program; originally developed by Boeing, the prime contractor role was transferred during development. After launch, the spacecraft reportedly failed to respond to ground commands. As reentry approached in early 2008, the decision was made to use an AEGIS SM-3 to intercept the satellite.
Mass was about 2300 kg, including 450 kg of hydrazine.
The second stage was placed in a low orbit and probably reentered after a few days.
