Northrop Grumman Systems Corporation

Northrop Grumman Systems Corporation, a wholly owned subsidiary of Northrop Grumman Corporation, manufactures and supplies aerospace and defense components, aircraft parts, and repair and sustainment services to the Department of Defense as a prime contractor, competing predominantly in full-and-open procurement without set-asides. Headquartered in Oklahoma City, Oklahoma, with multiple operating locations including El Segundo and Gardena, California, Northrop Grumman Systems Corporation (doing business as Northrop Grumman Systems Corp and Northrop Grumman Technical Services) operates under primary NAICS codes 336413 (Aircraft Parts and Auxiliary Equipment Manufacturing) and related PSC categories covering structural components, electrical and mechanical assemblies, and aircraft maintenance and repair services.

The company's customer base concentrates heavily on Air Force sustainment. The Air Force Sustainment Center (Air Force Materiel Command) anchors the portfolio with 100 awards worth $2.16 billion in combined potential value—91% of the vendor's tracked federal dollars—while the Defense Logistics Agency Aviation drives volume with 129 awards valued at $179.1 million. These two customers account for 97% of recent awards. Air Combat Command and DLA Land and Maritime contribute $34.4 million and $1.7 million respectively, with the remaining activity scattered across aeronautical systems and other Air Force components. The extreme concentration by dollar value (Air Force Sustainment Center) versus volume (DLA Aviation) reflects a mix of large-dollar sustainment contracts under single-award IDCs and numerous smaller component purchase orders.

Northrop Grumman Systems Corporation holds five named parent indefinite delivery contracts worth $534.5 million in combined potential value. The largest is a $495 million single-award IDC with the Air Force Sustainment Center (awarded July 2025, through July 2030) for specialized technical experience and OEM engineering data supporting the 448th Strategic Control Wing's managed end items and piece parts. A $35.1 million single-award IDC (awarded November 2025, through November 2030) covers repair and overhaul of B-2 tailpipe ducts and assemblies at El Segundo; one delivery order valued at $4.6 million was issued in December 2025 with completion by May 2026. Two legacy IDCs total $2.4 million ceiling: a $1.4 million B-2 Ground Handling Adapter repair IDC (through January 2029, nine delivery orders issued to date) and a $1.0 million B-2 power supply repair and calibration IDC (through September 2028). The vendor also works under at least five DLA Aviation IDC vehicles (FA811917D0003, FA811920D0003, FA811924D0004, FA811917D0010, and others), with task orders for component procurement and electrical equipment supply.

Capability work centers on B-2 stealth bomber sustainment and Air Force aircraft parts supply. Representative prime contracts include a $264.9 million cost-plus-fixed-fee delivery order (awarded December 2025, completion July 2034) for rudder components; an $84.8 million firm-fixed-price delivery order (April 2024, completion March 2029) for B-2 tailpipe forward duct assemblies; a $134.1 million delivery order (September 2024, completion October 2028) for B-2 Tailpipes Phase II overhaul and repair; an $11.2 million firm-fixed-price definitive contract (January 2025, completion July 2031) for B-2 product support services at Whiteman Air Force Base, Missouri; a $46.0 million definitive contract (December 2022, completion November 2028) for B-2 aircraft rudder and elevon composite flight control surfaces including first-article testing, with subcontractors Prime Machine Inc., Hexcel Corp, Advanced Composite Products and Technology Inc., and Roc-Aire Corp.; and a $13.76 million B-2 Mission Planning contract with Air Combat Command (December 2022, completion November 2027). Beyond B-2 work, the vendor supplies conduit assemblies, thermal insulation, wiring harnesses, connectors, fasteners, exhaust system components, and electrical components through DLA Aviation purchase orders. Aircraft access doors, bleed duct assemblies, safety relief valves, and RF filters represent higher-dollar component categories. A $1.95 million purchase order (November 2023, completion November 2025) for radio frequency filters from DLA Aviation, with Federal Industries (United Valve Company) as subcontractor, illustrates the vendor's electrical and electronic component supply reach.

Activity has accelerated over the reporting period: 27 awards in 2022, 19 in 2023, 42 in 2024, and 49 in 2025. Thirty awards with combined potential value of $43.9 million reach ultimate completion within the next twenty-four months, exposing the vendor to recompete risk primarily in B-2 tailpipe and ground handling adapter work and in routine DLA Aviation component replenishment.

The vendor operates predominantly as a prime contractor (95% of awards), with only 13 sub-awards documented; Northrop Grumman Systems Corporation subcontracts under CAE USA Inc. on B-2 training and aircrew instruction work and under Rockwell Collins (now Collins Aerospace) on C/KC-135 avionics sustaining engineering. Across SCI-reportable service contracts (a strict subset excluding goods and micro-purchases), the vendor invoiced $3.3 million in federal services revenue from FY2022 through FY2024, with $3.1 million in FY2023 across 8.6 FTEs and $194 thousand in FY2024 across 2.2 FTEs; median government-paid hourly rates on prime contracts run around $109/hr, ranging from $56/hr at the 10th percentile to $162/hr at the 90th percentile. SCI self-performance is near total (0% average subcontractor hours share), indicating the vendor builds internal labor for service work. The combined $1.26 billion obligated across all awards represents 53% of combined potential value, reflecting both completed and ongoing work across a multi-year B-2 sustainment engagement and a large base of component replenishment orders.
