**Buyer:** NAVSEA
**Posted:** October 07, 2026
**Respond By:** November 25, 2026
**Identifier:** DON27BZ01-NV003
**NAICS:** 541715, 332999

The Department of the Navy is seeking SBIR research and development proposals for an improved cargo door actuator for DDG-51 Class destroyers.
- Government buyer: Department of the Navy, through Naval Sea Systems Command (NAVSEA) and the DON SBIR/STTR Program Management Office.
- Core requirement: Develop an improved, corrosion-resistant cargo door actuator that can withstand saltwater, marine fuel, and other chemicals; meet mechanical and safety requirements for heavy doors; and closely match the existing actuator’s form, fit, and function.
  - The actuator should be cost-effective over its life cycle and easy for Navy personnel to maintain, repair, or replace.
  - No commercial part number, purchase quantity, or OEM/vendor is identified.
- Development scope: Phase I covers concept development and feasibility demonstration. Follow-on work may include prototype development, maritime testing, Navy transition planning, and fleet-use documentation.
- Phase I terms: The Navy topic specifies a six-month base period and a separate six-month option, with cost caps of $200,000 and $115,000, respectively.
- The broader Navy release also lists research topics for a TDR tank-level sensor cleaner, fire-resistant joiner bulkhead, secure shipboard signal-processing IOU, and intermediate-temperature cooling unit; these are separate from the cargo actuator topic.
- No OEMs or vendors are named in the provided materials.
