CLASS JUSTIFICATION AND APPROVAL (CJ&A) FOR MEDIUM LANDING SHIP BLOCK 1 CONSTRUCTION

This document is a Class Justification and Approval (CJ&A) for use of other than full and open competition, issued by the Department of the Navy's Naval Sea Systems Command, Shipbuilding Contracts Division (SEA 022). The CJ&A authorizes the award of a class of contractual actions for construction of up to four Medium Landing Ship (LSM) Block 1 vessels using the Landing Ship Transport (LST) 100 design. Authority under this approval expires September 30, 2031. The contract actions will be awarded either directly by the Navy or as a directed subcontract through the Navy's Vessel Construction Manager (VCM) on a sole-source basis to Fincantieri Marinette Marine (FMM). The contract scope includes construction of the vessels, associated design artifacts, specifications, data rights, and technical information necessary to operate and maintain the vessels and support future alterations for Government-Furnished Equipment. The Navy also intends to issue provisioned item orders (PIOs) for materials and engineering support related to this effort.

The Navy justified the single-source award to FMM under 10 U.S.C. § 3204(a)(3) to maintain the industrial base and achieve industrial mobilization. The Navy determined that FMM is essential to maintaining a balanced and resilient source of supply for concurrent LSM production across multiple shipyards, particularly given that only three shipyards other than FMM have demonstrated interest in the requirement and the urgent need to field LSMs to the fleet. The contracting officer determined the anticipated costs are fair and reasonable. The Navy indicated it intends to compete all future LSM requirements either directly or through the competitively awarded VCM contract. The Senior Procurement Executive approved this solicitation on February 17, 2026. The estimated total dollar value for fiscal years 2025-2031 was redacted from the document.
