Lockheed Martin is developing the Aegis ballistic missile defence (BMD) capability for the Aegis combat system to engage ballistic missiles with the SM-3 missile. 15 Arleigh Burke destroyers have been fitted with the Aegis BMD system, which provides the capability for long-range surveillance, tracking and engagement of short and medium-range ballistic missiles. The system received US Navy certification for full deployment in September 2006. Work was completed on the 15 destroyers at the end of 2008 and the vessels, with three Ticonderoga cruisers, form the Aegis BMD fleet.
