The Naval Sea Systems Command (NAVSEA) issues solicitation N00024-26-R-6311 for Operations and Sustainment (O&S) for the Littoral Combat Ship (LCS) Mission Modules (MMs) and Small Unmanned Surface Vessels (sUSVs). Program Executive Office Unmanned and Small Combatants (PEO USC), LCS MM Office (PMS 420) is procuring the effort required for the operations and sustainment of the LCS MMs and sUSVs.

LCS MMs support the LCS fleet in its mission to defeat asymmetric threats and to ensure naval and joint force access into congested littoral regions. The LCS MM Program has employed an incremental development approach to deliver capabilities, allowing for insertion of mature capabilities throughout the life of the program without the need for modifications to the LCS seaframe. The LCS MM Program is also the integrator of separately procured MM equipment (e.g., berthing augmentation, gun and missile weapon systems, mine countermeasures payload delivery systems, etc.) and sUSVs (e.g. interceptors, maritime domain awareness, logistics, etc.).  LCS MM Program product lines make use of common support containers, designs for which are based upon an International Organization for Standardization (ISO)-compliant shipping container (i.e., Conex box) to preserve anonymity and provide “roll on, roll off” capabilities for LCS seaframe and sUSV primary mission sets.
