LCS SUW Mission Modules

The LCS SUW Mission Modules program is a Navy initiative funded under budget line item 1603, designed to enhance the Littoral Combat Ship's (LCS) capabilities in surface warfare. The primary goal of this program is to increase the firepower and defensive/offensive capabilities of LCS vessels against fast, highly maneuverable small craft threats. This enables the Navy to protect sea lanes and rapidly maneuver through strategic waterways. The Surface Warfare (SUW) Mission Package is modular, allowing for flexible deployment and tailored mission sets based on operational needs.

The Gun Mission Module (GMM) is a key component of the SUW Mission Package, consisting of two high-velocity 30mm cannons that supplement the ship's 57mm gun. The GMM also integrates support aircraft, including the MH-60R helicopter equipped with Hellfire missiles and the MQ-8B Fire Scout VTUAV, which provide enhanced detection, identification, and classification of surface contacts. Program objectives include procurement and modernization of the GMM, specifically through technology refreshes such as the Gun Module Remote Control System (GMRCS) and Gun User Interface Device (GUID). These upgrades replace end-of-life computational equipment to maintain operational effectiveness.

The Surface-to-Surface Missile Module (SSMM) equips the LCS with the ability to engage sea-based and shore-based threats using the Army's Longbow Hellfire missile. The SSMM is composed of the MK 61 MOD 0 SSMM Enclosure and MK 210 Launchers, forming a self-contained launcher system with remote operation capabilities. The module is designed to counter Fast Attack Craft/Fast In-shore Attack Craft (FAC/FIAC) threats, providing standoff engagement capability. Budget objectives for the SSMM include procurement of launcher sets, engineering change proposals to support producibility, and production engineering for factory acceptance testing and technical support.

The Maritime Security Module (MSM) enhances the LCS's ability to conduct Level II Visit, Board, Search, and Seizure (VBSS) operations, as well as anti-piracy and maritime interdiction missions. The MSM includes hardware procurement for two 11-meter Rigid Hull Inflatable Boats (RHIBs), boat cradles, communications and tactical equipment, and support containers. Funding also covers production, assembly, installation, and system checkout, ensuring the module meets operational requirements for maritime security operations.

The SUW MP Obsolete/Tech Refresh line addresses the replacement of obsolete commercial off-the-shelf (COTS) components within the SUW Mission Package, such as computers, navigation systems, HVAC components, sensors, and other critical hardware. This objective is essential for maintaining the reliability and sustainability of the mission modules. The deployed GMMs, MSMs, and SSMMs face increasing obsolescence and sparing challenges. The budget supports modernization efforts to ensure continued operational readiness and effectiveness.

The Consulting Services budget line provides program management, engineering, technical support, studies, analysis, and evaluation for the SUW Mission Modules. These services are necessary for ongoing oversight, system integration, and performance assessment, supporting the Navy's ability to adapt the modules to evolving threats and operational requirements. The FY 2026 request for consulting services was reduced to promote cost efficiencies in alignment with Executive Order 14222.
