Northrop Grumman Systems Corporation

Northrop Grumman Systems Corporation Marine Systems Division, doing business as Northrop Grumman IS, operates as a direct supplier of mechanical, electrical, and structural components for military aircraft, naval vessels, and defense systems to the federal government, competing as a large prime contractor without set-aside protections across nearly all awards (98% prime). The division is a subsidiary of Northrop Grumman Corporation, headquartered in Falls Church, Virginia, and executes work from its primary facility in Sunnyvale, California.

The Marine Systems Division's capability portfolio centers on high-volume spare parts procurement and component logistics for defense platforms. Concrete work includes sleeve bushings, STEM fluid valves, gaskets, seals, turbine liners, wiring harnesses, bearing and shaft components, and specialized fasteners spanning aviation and maritime applications. Representative recent awards include a $31.56 million definitive contract with Naval Strategic Systems Programs for Trident II launcher long lead material procurement (December 2025), a $225.6 million delivery order with Naval Supply Systems Command for seat and valve components (April 2026), a $1.01 million definitive contract with Naval Supply Systems Command for STEM subassembly (July 2026), and a $384.8 million delivery order with Defense Logistics Agency Aviation for turnbuckle components (November 2025). The division executes hundreds of smaller delivery orders ranging from under $1,000 to several hundred thousand dollars under DLA Aviation basic ordering agreements.

Customer concentration is heavily weighted to defense logistics. The top five funding agencies account for 91% of recent awards. Defense Logistics Agency Aviation dominates by award count (2,056 awards, $1.12 billion combined potential value), followed by Department of the Navy Naval Supply Systems Command (1,004 awards, $79.1 million), Defense Logistics Agency Land and Maritime (761 awards, $24.1 million), Defense Logistics Agency Troop Support Hardware (354 awards, $3.5 million), and Department of the Navy Naval Sea Systems Command (300 awards, $230.5 million). By potential value, the top ranking shifts: Department of the Navy Strategic Systems Programs leads with 115 awards valued at $1.24 billion combined, followed by DLA Aviation at $1.12 billion. This split reflects Strategic Systems Programs' larger individual contract values (particularly the Trident II program work) versus DLA Aviation's high-volume transactional model.

The division's primary vehicle footprint comprises five basic ordering agreements and indefinite delivery contracts. Two DLA Aviation BOAs dominate the portfolio: SPE4A117G0003 with 1,210 task orders worth $54.9 million combined potential value and SPE4A122G0004 with 1,134 task orders worth $54.2 million, both running through February 2027. Additional significant vehicles include DLA Troop Support BOA SPM4A111G0006 (765 task orders, $19.5 million), an indefinite delivery contract SPM7AX06G0002 (376 task orders, $13.2 million), and SP070003G0001 (182 task orders, $317 thousand). Task order counts reflect streamlined procurement under established frameworks rather than competitive re-solicitation on individual orders.

Award activity has grown substantially year over year, from 216 awards in 2022 to 447 in 2025, with 80 awards recorded in 2026 to date. Within the next twenty-four months, 281 awards reach ultimate completion with combined potential value of $140.6 million, presenting significant recompete exposure across the DLA Aviation and Naval Supply Systems Command portfolios where the division holds fortress-like positioning through its two primary BOAs.

SCI-reported invoicing for federal service contracts above the $150,000 threshold shows $598.4 million across FY2022–FY2025, with FY2024 invoicing of $170 million across 333 FTEs and FY2025 invoicing of $143.5 million across 326 FTEs. Government-paid hourly rates on SCI-reportable contracts run a median of $191.15/hr with senior labor pricing reaching the 90th percentile of $327.71/hr, positioning the division at mid-to-premium pricing for mechanical and logistics support work. Across SCI-reportable prime contracts, subcontractors represent approximately 1% of contractor hours, with only three named subcontractors reported, confirming the division's model as a direct supplier and manufacturer with minimal subcontractor reliance.

The Marine Systems Division operates primarily as a prime contractor, with 98% of recent awards structured as prime contracts and only 2% as subcontracts. The subcontract footprint is limited but strategically significant: recent sub-awards to Huntington Ingalls Inc. focus on CVN 75 Refueling and Complex Overhaul advance planning and CVN 80 engineering efforts, with component-level deliverables spanning turbine components, seals, valves, bearings, fasteners, and thermal management hardware for naval carrier refurbishment. This teaming pattern reflects the division's role as a specialized supplier and component manufacturer rather than a systems integrator; it feeds established primes on major shipbuilding and platform modernization efforts while maintaining dominant volume through its own DLA-direct spare parts logistics position.

Work is performed at the Sunnyvale, California facility with subordinate delivery across military aviation, maritime, and strategic missile programs nationwide. The top category concentrations by NAICS reflect the division's component focus: Other Aircraft Parts and Auxiliary Equipment Manufacturing (2,104 awards), Switchgear and Switchboard Apparatus Manufacturing (1,138 awards), and All Other Miscellaneous General Purpose Machinery Manufacturing (390 awards). Top PSC categories include Packing and Gasket Materials (628 awards), Steam Turbines and Components (526 awards), and Valves, Nonpowered (402 awards), confirming mechanical and fluid systems specialization across defense platforms.
