Northrop Grumman Systems Corporation

Northrop Grumman Systems Corporation, doing business as Electronic Systems Company (Esco), is a subsidiary of Northrop Grumman Corporation that operates as a large prime contractor delivering radar systems, advanced electronics, software development, and engineering services to the U.S. Marine Corps and Army without set-aside designation. The company competes full-and-open across defense platforms and does not hold SBA certifications.

Esco's federal footprint is dominated by Ground/Air Task Oriented Radar (G/ATOR) development and sustainment work for the Marine Corps. Recent representative G/ATOR awards include a $16.26 million cost-plus-fixed-fee delivery order (August 2026) for digital receiver/exciter component-level subsystem design and development, a $39.4 million sustainment engineering delivery order (September 2025) for software development, a $40.5 million engineering support delivery order (April 2024) for Expeditionary Capability Package development and Digital Radar Exploitation testing, and a $59.65 million firm fixed-price contract (April 2023) for spares and initial issue provisioning. Esco has accumulated over $1.5 billion in G/ATOR production contracts and numerous sustainment orders. The company also delivers network infrastructure, cybersecurity, and logistics support across G/ATOR and related Marine Corps C4ISR systems. Army work spans communications equipment manufacturing, electronic assemblies, and engineering services through Aberdeen Proving Ground and CECOM contracting channels.

Customer concentration is stark. Of 262 total awards tracked across prime and sub work, the Marine Corps accounts for 26 awards but commands $3.24 billion in combined potential value—approximately 76% of Esco's entire federal award portfolio. The top five customers (covering 73% of award count and 98% of potential value) are the Marine Corps, Army Materiel Command Aberdeen Proving Ground (57 awards, $478.8 million), Army Acquisition Support Center PEO Enterprise Information Systems (22 awards, $286.9 million), Army Communications Electronics Command (35 awards, $112 million), and Army Mission and Installation Contracting Command Fort Belvoir (1 award, $55.5 million). The Marine Corps-Army split reflects Esco's positioning as a radar and electronic systems specialist aligned with Marine Corps air defense and Navy aviation modernization priorities, with secondary Army revenue in communications and IT infrastructure.

Esco places task orders under five named indefinite delivery vehicles: Indefinite Delivery Contract DAAB0702DD001 (58 task orders, $123.9 million), Indefinite Delivery Contract W15P7T07DL002 (35 task orders, $830.2 million), Basic Ordering Agreement M6785420G0032 (19 task orders, $417.8 million), Indefinite Delivery Contract DAAB0700DD902 (17 task orders), and Indefinite Delivery Contract W15P7T04DH602 (9 task orders, $190 thousand). These vehicles represent standing procurement relationships with the Marine Corps and Army for sustainment engineering, logistics support, communications equipment production, and radar development activities.

Activity has grown over the past five years, from four awards in 2022 to seventeen in 2025, with three awards recorded in 2026 to date. Five awards (combined potential value $142.8 million) complete within the next twenty-four months, representing moderate recompete exposure concentrated on G/ATOR and related Marine Corps sustainment task orders. Esco operates predominantly as a prime contractor (88% of awards) and engages an established subcontractor network for specialized components and services; named subcontractors include Saab Inc., General Dynamics, Telephonics, Curtiss-Wright Controls Electronic Systems, SRC Inc., Marki Microwave, Moog Inc., and smaller specialized suppliers in microwave components and precision fabrication. When Esco subcontracts as a sub (12% of awards), it performs radar systems engineering, software sustainment, and avionics systems work under Boeing (P-8A and AWACS programs, Disruptive Futures Modular Missile Systems, F/A-18E sustainment), HII Mission Technologies (C4ISR research and development at Tobyhanna Army Depot), and CAE USA (F-16 training simulator AESA radar integration).

SCI-reported invoicing totaled $35.4 million in FY2024 across 79 FTEs on five prime service contracts (FY2022 and FY2023 SCI records show zero invoicing and zero FTEs, reflecting recent capture into the SCI dataset). On federal services contracts captured in SCI, government-paid hourly rates ranged from a 10th percentile of $64.93/hr to a median of $184.51/hr and a 90th percentile of $523.11/hr, reflecting a mix of junior technical labor and senior engineering and program management staff. SCI records show negligible sub-hours engagement across prime contracts, indicating Esco builds most of its delivery teams internally on these particular service contracts. SCI data represents a strict subset of Esco's federal revenue and excludes the G/ATOR production and spares contracts that dominate the portfolio by dollar value.
