Raytheon [RTN] has delivered the 28th Ship Self-Defense System (SSDS MK 2), which is designed to protect aircraft carriers and expeditionary warships from anti-ship cruise missiles, the company said recently.

The system meets Navy standards on open architecture (OA) and will upgrade legacy combat systems, the company statement said.

The SSDS M2 is designed to expedite the detect-to-engage sequence to defend against cruise missiles. The system links and automates standalone sensors and weapon systems to provide the required combat reaction.

Under the contract, Raytheon is responsible for the assembly, testing and delivery of the hardware sets for integration on the ships.
