About this opportunity
The Department of the Navy Naval Sea Systems Command is soliciting proposals for Unmanned Maritime Systems (UMS) support services under Request for Proposal N6133126R3102, issued through the Seaport NxG Multiple Award Contract (MAC) framework. This engineering services procurement seeks qualified contractors to provide professional engineering and technical support for unmanned maritime systems operations and development. Eligibility is strictly limited to current Seaport NxG MAC holders, and all responses must be submitted through the PIEE solicitation module by January 16, 2026 at 4:00 PM CST. The solicitation builds upon previous industry engagement, including a Source Sought Notice issued on June 13, 2025, and an Advance Planning Notice/Pre-Solicitation Notice dated August 20, 2025. Contractors should reference the official Seaport announcement and its Amendment Log for complete RFP details, evaluation criteria, and any updates to requirements or deadlines.
This opportunity is designated as a Service-Disabled Veteran-Owned Small Business (SDVOSB) set-aside, restricting award eligibility to qualified businesses meeting this small business designation. The solicitation does not specify an incumbent contractor or disclosed budget ceiling, though contractors should review the complete Seaport NxG announcement for contract value information and cost estimates. The contract is classified under NAICS 541330 (Engineering Services) and PSC R425 (Support—Professional: Engineering/Technical), indicating a focus on specialized technical expertise. While specific performance timelines and quantities are not detailed in this notice, contractors should expect multi-year MAC performance requirements consistent with Seaport NxG contract vehicles. The location of performance and additional contractual details are available within the official RFP documentation on the Seaport opportunities portal.
