LOCKHEED MARTIN Astronautics has selected an upgraded version of the Agena upper-stage rocket engine for its entry into the US Air Force's Evolved Expendable Launch Vehicle (EELV) competition.

Team Agena 2000, consisting of Atlantic Research and Aerojet, is to provide a modified Agena storable-propellant main axial engine to power the new upper stage which Lockheed Martin plans to develop for the EELV. The EELV family is to replace McDonnell Douglas Delta and Lockheed Martin Atlas and Titan launchers and can place medium, intermediate and heavy payloads into orbits.
