Seaport Next Generation (Seaport-NXG)

The Department of the Navy Naval Sea Systems Command awarded Seaport Next Generation, a multiple-award master IDIQ, on January 2, 2019, with ordering authority extending through December 31, 2028—approximately 2 years and 5 months remaining. The vehicle succeeded SeaPort-e and carries a combined potential value of $101.34 billion across 4,655 task orders issued to 2,888 distinct primes, with $32.72 billion obligated (32% of combined potential value).

Recent ordering momentum has accelerated significantly: after averaging 276 orders annually from 2022 through 2024, the vehicle issued 1,280 orders in 2025 before settling to 90 orders in 2026 year-to-date. The most recent award was in September 2026, confirming active procurement.

Seaport-NXG funds engineering services and program management across the Navy enterprise. Task order descriptions reveal scope spanning combat systems engineering, C5ISR systems integration, software development and cyber security, platform integration and lifecycle support, undersea warfare systems, ship control and propulsion systems, training and personnel support, and technical logistics. Cost-plus-fixed-fee and cost-plus-award-fee arrangements dominate, with firm-fixed-price orders for administrative and training support.

Competitive concentration is moderate among primes. Booz Allen Hamilton leads by both order count (57 orders) and potential value ($5.5 billion), followed by Science Applications International Corporation (54 orders, $3.36 billion combined potential value) and Serco Inc. (28 orders, $2.4 billion). The top five primes by potential value account for roughly 15% of combined potential, indicating a broad-based competitive landscape across 2,888 awardees.

Customer concentration is heavily skewed toward Naval Sea Systems Command (NAVSEA), which placed 3,509 orders valued at $60.55 billion in combined potential—roughly 75% of vehicle activity. The Information Warfare Systems Command follows distantly with 251 orders and $17.61 billion combined potential value. The remaining funding agencies collectively account for less than 12% of task orders.

The vehicle is 96% unrestricted competition; small-business set-asides represent 3% of orders, service-disabled veteran-owned small business 1%, and remaining socioeconomic categories less than 1% combined. Typical task-order ceilings range from roughly $9 million to over $300 million, with representative recent awards at $80.2 million, $143.9 million, and $308.8 million. Place of performance spans Naval Sea Systems Command field activities (Naval Surface Warfare Center Dahlgren, Newport, Indian Head), Naval Air Warfare Center divisions (Lakehurst, Patuxent River), Naval Submarine Warfare Center, and dispersed Navy activity locations.

Awardees of the Seaport-NXG IDIQ provide qualified personnel, materials, facilities, equipment, test instrumentation, data collection and analysis, hardware and software, and other services to support the Department of the Navy (DON) in the execution of its overall organizational functions and the specific missions of the individual activities and ordering offices. This includes services that potentially span the entire spectrum of mission areas and technical capabilities supported by the DON ordering activities. Seaport-NXG awards fall into two broad categories; Engineering Services and Program Management Services.
