Quick Summary
The Department of the Navy (DEPT OF THE NAVY), specifically NAVSEA HQ, has published a Redacted Justification and Approval (J&A) for a sole-source contract modification. This J&A concerns the US Mark 11 (MK11) Sea, Air, and Land (SEAL) Delivery Vehicles (SDV) Performance Extension, providing continued engineering and technical support for the MK11 Shallow Water Combat Submersible (SDV) program. The modification is for contract N00024-19-C-6402 with Teledyne Brown Engineering (TBE), extending its period of performance through the end of the fiscal year. This is not a solicitation for proposals.
Scope of Work
The contract modification with Teledyne Brown Engineering (TBE) will provide:
- Increased labor hours for engineering and technical support.
- Increased Provisioned Item Orders (PIO) maximum value for material obsolescence and component replacements.
- Support for MK11 SDV design alterations and new capabilities.
- In-service vehicle maintenance.
- Other engineering and technical support as directed by Technical Instructions.
- Travel and ancillary Other Direct Costs (ODCs).
Contract Details
- Type: Sole-source modification to an existing contract (N00024-19-C-6402).
- Contractor: Teledyne Brown Engineering (TBE).
- Duration: Period of Performance extended through the end of the fiscal year.
- Set-Aside: This is a sole-source action; no set-aside applies.
- Authority: Justified under 10 U.S.C. 3204(a)(1).
- Place of Performance: Huntsville, AL.
- Published Date: February 5, 2026.
Rationale for Sole-Source
The government determined that Teledyne Brown Engineering (TBE) is the only responsible source due to their unique knowledge of the MK11 SDV system design and current production capability. Market research confirmed no other contractor possesses the necessary Note 5000 certification or manufacturing capacity for immediate performance. Awarding to any other contractor would result in unacceptable delays in fulfilling government requirements.
Future Considerations
The government plans to assess future competition for overhaul and sustainment requirements related to the MK11 SDV program.
