USA-186 (also known as KH-11 14 and NROL-20) is an American reconnaissance satellite which is operated by the National Reconnaissance Office. Launched in October 2005, it is the first KH-11 Block 4 reconnaissance satellite.[2][3][4][5][6]

Overview

The satellite launched on the Last Titan IV launch and is last Titan rocket launch and ending its many decades of service to US National Security missions, future KH-11 mission will be launch on the Delta IV Heavy rocket.[7]
