Northrop Grumman Systems Corporation

Northrop Grumman Systems Corporation Marine Systems Division, doing business as Northrop Grumman IS, manufactures mechanical, electrical, and structural components for military aircraft, naval vessels, and defense systems, operating as a prime contractor (98% of recent awards) on spare parts procurement and equipment logistics for the Department of Defense.

The Marine Systems division is a subsidiary of Northrop Grumman Systems Corporation, a for-profit manufacturer of goods headquartered in Falls Church, Virginia. Northrop Grumman competes on full-and-open basis—no set-aside designations appear across its award footprint. The division specializes in concrete capability delivery: valves (stem fluid, safety relief, ball, steam chest), seals and seal rings (metal, gland, exhaust, lip), gaskets, turbine liners, bushings, fasteners, wiring harnesses, shaft components, and specialized tooling. Recent representative work includes a $31.56 million cost-plus-fixed-fee definitive contract with Naval Strategic Systems Programs for Trident II (D-5) launcher long lead material procurement (awarded December 2025, completion December 2027); an $8.58 million firm fixed-price contract with Naval Sea Systems Command for Ship Service Turbine Generator repair materials on Virginia-class submarines USS Delaware and USS Mississippi (awarded September 2025, completion December 2027); and a $4.42 million definitive contract with Naval Sea Systems Command for Ships Service Turbine Generator material (awarded September 2025, completion July 2027). The division also executes hundreds of smaller delivery orders under Defense Logistics Agency Basic Ordering Agreements—exemplified by individual orders valued from $888 to $384,792 for mechanical hardware across aviation and maritime platforms.

Customer concentration is extreme and strategically distributed. DLA Aviation anchors the portfolio with 2,028 awards ($1.12 billion combined potential value, 49% of all dollars), followed by Naval Strategic Systems Programs with 115 awards ($775 million, 34% of all dollars), Naval Sea Systems Command with 300 awards ($230.3 million), Naval Supply Systems Command with 999 awards ($77.6 million), and DLA Land & Maritime with 761 awards ($24.2 million). These five agencies account for 98% of combined potential value. The concentration split between volume (DLA Aviation dominating award count) and dollars (Strategic Systems Programs anchoring value through fewer, larger awards) signals a dual-track business model: high-volume spare parts logistics to DLA Aviation and strategic component supply to Navy shipbuilding and ballistic missile programs.

The Marine Systems division operates primarily through two high-volume BOAs: Basic Ordering Agreement SPE4A117G0003 (1,210 task orders, $54.9 million potential value) and SPE4A122G0004 (1,106 task orders, $54 million), both with DLA Aviation running through early 2027. Two additional vehicles anchor larger strategic work: Indefinite Delivery Contract SP070003G0001 with Naval Strategic Systems Programs (182 task orders, $317 thousand reported; actual strategic value concentrated in definitives executed under related authorities) and IDC SPM7AX06G0002 (376 task orders, $13.2 million). The BOA structure with DLA—each $10 million through February 2027—enables rapid, streamlined delivery of component-level spare parts without formal competition on individual orders, a model the division executes at scale with cumulative task orders exceeding $2 million per BOA.

Recent activity shows growth through 2024 followed by partial-year 2025–2026 data: 216 awards in 2022, 239 in 2023, 441 in 2024, 445 in 2025, and 49 in the partial 2026 snapshot. This trajectory signals sustained high-volume procurement, though the recompete cliff window (next 24 months) exposes 346 awards worth $186.7 million in combined potential value to recompete—a material exposure given the concentration in BOAs and definitives with near-term completions (February 2027 for DLA Aviation BOAs).

Across SCI-reportable federal service contracts, the Marine Systems division reported $454.9 million in invoiced revenue spanning FY2022–FY2024 (FY2022: $130.4 million across 308 FTEs; FY2023: $154.6 million across 321 FTEs; FY2024: $170 million across 333 FTEs). These figures capture only service contracts above the $150,000 reporting threshold and exclude the vast majority of the division's goods-based spare parts business. Government-paid hourly rates on SCI-reportable contracts median around $191/hr, with senior labor pricing through $327/hr. Across SCI prime contracts, subcontractors account for roughly 1% of total hours—the division builds its own delivery teams and sources three named subcontractors for specialized support. This low sub-engagement aligns with its role as a direct supplier and manufacturer rather than a systems integrator.

The division subcontracts to Huntington Ingalls Inc. on CVN-class aircraft carrier overhaul and modernization work, delivering turbine generator components, valves, gaskets, springs, fasteners, and associated structural hardware in support of engineering and advance planning phases for USS Dwight D. Eisenhower (CVN-75) refueling and complex overhaul (RCOH) and USS George H.W. Bush (CVN-80) construction. These sub-awards, ranging from component supply to proposal preparation support, reflect the division's niche as a critical supplier within larger defense industrial programs. No other named prime subcontracting relationships appear in the source material; the focus is on direct prime awards from DLA and Navy agencies.

Northrop Grumman Systems Corporation Marine Systems Division operates as a high-volume, specialized logistics and component supplier to defense agencies with a fortress position in DLA Aviation spare parts procurement and a strategic role in Navy strategic systems and shipbuilding programs. Recompete risk over the next 24 months is material ($186.7 million in awards nearing completion), and the concentration in BOAs expiring February 2027 presents both renewal opportunity and competitive exposure.
