Northrop Grumman Systems Corporation

Northrop Grumman Systems Corporation Land And Self Protection Systems Division, operating as Denro Systems, provides maintenance, repair, and remanufacturing services for self-defense vehicle system components and aviation electronics to the Air Force and Federal Aviation Administration as a prime contractor under full-and-open competition with no set-aside designation. Denro Systems is a division of Northrop Grumman Systems Corporation, a subsidiary of the aerospace and defense contractor Northrop Grumman Corporation, and competes across federal procurements without SBA certifications.

Denro Systems' federal footprint concentrates heavily on repair and sustainment of aviation and electronic systems. The vendor holds a $2.2 million single-award IDIQ with the Air Force Air Education and Training Command covering maintenance, diagnostics, remanufacturing, and component replacement for self-defense vehicle systems across five Air Force bases, from which it issues frequent firm-fixed-price delivery orders. Representative work includes a $51.7 thousand delivery order in October 2023 to service six self-defense vehicle system parts for Vance Air Force Base over one year, a $20.6 thousand delivery order in August 2023 to repair three SDVS parts for Sheppard Air Force Base, and a $1 million definitive time-and-materials contract awarded July 2023 for ARSR-4 antenna system maintenance and repair in Oklahoma City. Recent activity centers on Columbus Air Force Base and Vance Air Force Base, with delivery orders for repair of proximity ignition processors, operator processors, power supplies, and threat evaluation display modules valued in the range of $4,200 to $71,300 per order.

Customer concentration sits overwhelmingly with the Federal Aviation Administration and the Air Force. The FAA Technical Center accounts for $877.7 million of the $1.17 billion combined potential value across all 1,991 prime awards in the source data (75% of total portfolio value), though only two awards carry that value. FAA Headquarters represents 653 awards worth $244.7 million, and FAA Aeronautical Center represents 265 awards worth $21.4 million. The Air Force places 123 awards worth $4.9 million, the majority flowing to Denro Systems' SDVS IDIQ. The Defense Information Systems Agency accounts for 438 awards. Together, the top five customer agencies by award count cover 79% of all awards, with the top three agencies by potential value covering 99%.

Denro Systems' parent-vehicle footprint routes primarily through FAA-managed indefinite delivery contracts. The largest vehicle is Indefinite Delivery Contract DTFAAC14D00068 with 745 task orders worth $29.9 million combined potential value. Indefinite Delivery Contract DCA20093D0014 carries 375 task orders, and DTFAAC11D00073 carries 117 task orders worth $7.5 million. The vendor also places work under the Air Force's FA302215D0003 IDIQ (35 task orders, $451 thousand potential value) and Basic Ordering Agreement DAAB0782DD004 (53 task orders).

Activity has declined. The vendor received 11 awards in 2022, declining to 7 in 2023, 4 in 2024, 3 in 2025, and 1 award year-to-date through February 2026. One award with a combined potential value of $95.2 million carries an ultimate completion date in the next twenty-four months, presenting recompete exposure. The vendor operates as a 100% prime contractor with no subcontract footprint in the source data. Capability framing aligns with NAICS 336322 (Other Electronic and Precision Equipment Repair and Maintenance) and PSC 2F971 (Maintenance/Repair/Rebuild Of Equipment—Electrical And Electronic Equipment Components), reflecting the repair-focused nature of its federal work across avionics, self-defense electronics, and aviation system components.
