About this opportunity

The Department of the Navy Naval Sea Systems Command is soliciting proposals under RFP N61331-26-R-3101 for LCAC C4N and Cybersecurity Systems Program Support through the Seaport NxG Multiple Award Contract (MAC). This engineering services procurement seeks support for command, control, communications, and network (C4N) systems as well as cybersecurity capabilities for Landing Craft Air Cushion (LCAC) platforms. Eligibility is strictly limited to current Seaport MAC holders, which serves as a primary contract requirement for submission consideration. All proposals must be submitted through the PIEE Solicitation Module, and questions and answers will be conducted through the Seaport NxG Opportunities portal. The solicitation was posted on December 30, 2025, with a due date of January 30, 2026, indicating a compressed timeline for proposal submission.

This solicitation carries no small business set-aside designation and represents a competitive opportunity among existing Seaport MAC contractors. The effort builds on prior market research activities, including a Sources Sought Notice issued on January 23, 2025, and an Advance Planning Notice/Pre-Solicitation Notice from April 2025. The primary place of performance is located at 110 Vernon Ave, Panama City, Florida 32407, where LCAC-related operations and systems support activities are centered. While specific contract value and performance timeline details are not provided in this solicitation notice, contractors should consult the complete RFP documentation available within the Seaport Opportunities portal and review the Amendment Log for any updates or clarifications issued after the initial posting.
