Quick Summary
The Department of the Navy (NAVSEA HQ) has published a Justification for Other Than Full and Open Competition for LST-100 Design (Medium Landing Ship (LSM) Block 1) engineering and design agent support. This action modifies an existing contract (N00024-25-C-2414) with Damen Naval to increase the scope of work. The justification is based on 10 U.S.C. § 3204(a)(1), citing only one responsible source. The place of performance is Gorinchem, Netherlands. This justification is valid until September 30, 2031.
Scope of Work
This modification expands the scope to include engineering support for the Medium Landing Ship (LSM) Program and awards a directed subcontract to Damen Naval for engineering and design agent support for future LSM Block 1 procurements. Damen Naval will serve as the Design and Configuration Agent for construction subcontracts awarded by the Navy's Vessel Construction Manager (VCM). Services include:
- Design Baseline Management
- Configuration Control
- Engineering and Technical Support
- Support to Production for the LST 100 design
Contract & Timeline
- Type: Justification for Other Than Full and Open Competition (Modification to existing contract N00024-25-C-2414)
- Product/Service Code: 1905 (Combat Ships And Landing Vessels)
- Set-Aside: None (Sole Source Justification)
- Published Date: April 13, 2026
- Justification Validity: Until September 30, 2031
Justification & Rationale
The Navy asserts that Damen Naval is the original designer and builder of the LST 100. Awarding this scope to any other source would result in substantial cost duplication and unacceptable delays. Market research, including an RFI and a pre-solicitation synopsis on SAM.gov, identified Damen's LST 100 and Bollinger's ND-LSV as the only two mature designs meeting requirements, with the LST 100 selected as the official design basis. No responses from other potential sources were received during market research.
Additional Notes
The Navy currently has no plans to compete future contract actions for these specific supplies/services. The award date mentioned in the original description refers to the initial contract award, with this modification incorporating the scope increase.
