Raytheon Company delivered the 28th Ship Self-Defense System (SSDS MK 2) hardware ship set ahead of schedule. The ship sets will be installed on new ships and will also upgrade legacy combat management systems on in-service ships, bringing them up to U.S. Navy-certified open architecture (OA) standards.

SSDS is an open, distributed combat management system in service on carriers and expeditionary warfare ships. It is designed to expedite the detect-to-engage sequence to defend against anti-ship cruise missiles. SSDS links and automates standalone sensors and weapon systems to provide the required combat reaction.
