Phalanx CIWS SEARAM

Abstract

The MK 15 MOD 40 Close in Weapon System (CIWS) RAM Defense Capability (CRDC) configuration is fielded aboard Nimitz Class Carriers (CVN). It is a fast reaction, rapid fire, computer-controlled radar system that employs the Rolling Airframe Missile (RAM) as an effector for Anti-Ship Missile (ASM) defense. The MK 15 MOD 40 CIWS (CRDC) configuration was fielded in FY 2020, limited to the RAM BLK 2 missile variant. The purpose of this project is to develop and integrate the latest RAM missile variant (BLK 2B) into the MK 15 MOD 40 baseline. The RAM Block 2B missile defends against highly maneuverable Anti-Ship Cruise Missile (ASCM) threats and emerging complex raid attacks utilizing an advanced infrared (IR) seeker and Missile-to-Missile Link (MML) while maintaining all the proven capabilities of previous RAM variants (BLK 2): accurate terminal guidance, proven lethality, and post-launch fire and forget capability. Without this effort the Nimitz class carriers will be unable to utilize the latest and most capable RAM Block 2B missile which entered production in FY 2023.
