2003-054A
A new ocean surveillance SIGINT was launched in Dec 2003 on MLV-14. The Centaur IIA has two RL10A-4-1B engines. The unclassified launch name was Libra. Two satellites were deployed, rather than the expected three, confirming the new Atlas-launched system was a different design to its predecessors.
The satellites each made a stationkeeping burn to join the operational constellation on 2004 Mar 24.
