Modernization and Obsolescence Machinery Control Systems

Naval Sea Systems Command awarded this Master IDIQ on July 1, 2021, for systems engineering analysis, shipboard control systems troubleshooting, and fleet modernization and cyber security upgrades for DDG-51 machinery control systems, with ordering closed on June 29, 2026.

The vehicle is now closed to new orders and past its ceiling date. Eight prime contractors shared 17 task orders totaling $51.2 million in combined potential value, with $42.3 million already obligated (83% of capacity). Ordering momentum declined sharply: eight orders in 2021 tapered to five in 2022, then two orders each in 2023 and 2024, with the most recent award in August 2024. All task orders fund Navy programs exclusively through Naval Sea Systems Command.

Green Expert Technology Inc. dominates the vehicle, holding six orders worth $25.2 million in combined potential value—roughly 49% of the total. Noblis MSD LLC and EHS Technologies Corp each hold three orders, worth $12.9 million and $7.9 million respectively. These three primes account for 82% of task-order count and 94% of combined potential value; the remaining five primes hold one order each.

Scope centers on Arleigh Burke-class (DDG-51) machinery control systems across new construction, modernization, in-service engineering, and fleet sustainment. Work includes lifecycle engineering support, hybrid electric drive integration, software and systems engineering, shipboard troubleshooting and installation, product integration, cyber support, and technical refresh. Representative recent orders range from $4.8 million to $7.3 million in ceiling value, priced on a cost-plus-fixed-fee basis with performance periods through mid-2026.

The vehicle carries minimal set-aside designation: 16 of 17 orders (94%) are unrestricted, with a single total-small-business order awarded in August 2024. All work performed at the Land Based Engineering Site and Test Facilities in Philadelphia, Pennsylvania, or shipboard worldwide.

This IDIQ includes systems engineering analysis in order to interface control systems with other new or modified shipboard systems; troubleshooting control systems hardware and software issues at the Land Based Engineering Site (LBES) or Test Facilities in Philadelphia, PA, as well as sustainment and fleet modernization efforts around the world; upgrading the cyber security features of the existing and future control system variants; and addressing obsolete hardware with the most cost effective solutions possible.
