About this opportunity
The Naval Sea Systems Command seeks to modify Contract No. N00024-25-C-2414 through a sole-source justification to award a directed subcontract to Damen Naval for engineering and design agent support services for the Medium Landing Ship (LSM) Program. The services include design baseline management, configuration control, engineering and technical support, production support, technical data package management, and configuration control across multiple U.S. shipyards for the LST 100 design through fiscal year 2031. The Navy justifies the sole-source award under 10 U.S.C. § 3204(a)(1) because Damen is the original source of the LST 100 design, and any alternative contractor would incur substantial cost duplication and cause unacceptable schedule delays; this conclusion was reached following an industry-wide Request for Information issued on January 7, 2025, which identified only two mature designs meeting requirements. The estimated total value covers royalty fees for 15 ships plus engineering changes and design agent services across LSM Block 1 construction subcontracts. The CJ&A was approved on February 17, 2026, with authority expiring September 30, 2031, and the original contract was awarded on July 30, 2025.
Notice text
See attached redacted CJ&A in accordance with 10 U.S.C. § 3204(a)(1), only one responsible source and no other supplies or services will satisfy agency requirements.
Please note the following:
- The award date is based on the original contract award date. A future modification will be issued to incorporate the scope increase.
- The CJ&A is to increase the scope of work to include engineering support for the Medium Landing Ship (LSM) Program and award of a directed subcontract by the Navy’s Vessel Construction Manager (VCM) for engineering and design agent support for the future LSM Block 1 procurements.
Awarded contract N00024-25-C-2414 to unknown vendor for unknown amount on 2025-07-30.
