John H. Northrop & Associates, Inc.

John H. Northrop & Associates, Inc. (JHNA), a Service-Disabled Veteran-Owned Small Business based in Clifton, Virginia, provides systems engineering, professional technical and engineering services, and research and development support to the Department of Defense and civilian agencies as both a prime contractor (52% of recent awards) and as a subcontractor (48%) on major defense programs. JHNA competes predominantly under the SDVOSB set-aside, with recent prime awards split across full-and-open and SDVOSB-designated vehicles.

JHNA's prime award portfolio centers on defense engineering and R&D work. The vendor holds a $151 billion multiple-award IDIQ with the Missile Defense Agency under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program, awarded December 29, 2025, covering research and development, systems engineering, prototyping, weapon design, test and evaluation, and cybersecurity across classified and unclassified work with facility clearance requirements. JHNA also holds a multi-billion-dollar OASIS+ SDVOSB IDIQ (General Services Administration, awarded September 30, 2024) for integrated professional services in engineering, systems engineering, and program management across the federal government. On the Air Force side, JHNA operates under a $900 million multiple-award IDIQ with Air Force Life Cycle Management Center (AFLCMC/XA) for multi-domain systems capabilities and rapid prototyping (June 30, 2023, maturing November 14, 2027) and a $92 billion multiple-award Eglin Wide Agile Acquisition Contract (EWAAC) for armament and weapons development (February 25, 2022, through September 9, 2031). The vendor also holds a GSA Federal Supply Schedule contract with a $40 million ceiling (September 13, 2024, through September 12, 2029) covering engineering services, IT professional services, and engineering research and development across 39 labor categories ranging from $51.72 to $304.51 per hour. Recent representative delivery orders include a $28.1 million Total Small Business set-aside delivery order from the Army Research, Development and Engineering Command for professional engineering and analysis services supporting aviation mission systems research and development at Fort Eustis (November 17, 2023, through May 31, 2029), and a $3.6 million SDVOSB incremental funding award from the Army Training and Doctrine Command for training support at Fort Rucker, Alabama (August 28, 2024, through February 27, 2029).

Customer concentration is heavily weighted toward the Department of the Air Force, which accounts for $92.9 billion (100% of combined potential value across top-five customers) driven almost entirely by the EWAAC and SHIELD IDIQ vehicles. The Department of the Army Research, Development and Engineering Command places the second-largest concentration by count (10 awards, $61.2 million combined potential value), followed by GSA Federal Acquisition Service (3 awards, $83.7 million), the Army Training and Doctrine Command (1 award, $3.6 million), and the Navy Naval Air Systems Command (4 awards). The top customers by award count account for 59% of recent awards. The ranking by potential value is dominated by Air Force IDIQs, which represent structural capacity rather than active task order obligation — as of the source snapshot, only $63.1 million is obligated across the $93.05 billion combined potential value in recent prime and sub awards.

JHNA's capability portfolio concentrates on systems engineering, professional engineering analysis, and R&D support for aviation and defense platforms. The vendor subcontracts to primes including HII Mission Technologies Corp (power, mobility, and combat capabilities R&D for Army Combat Capabilities Development Command, July 2024 through April 2025), Modern Technology Solutions, Inc. (mission integration and technical engineering services under OUSD(R&E), August 2025 and December 2025), Georgia TECH Applied Research Corp (aviation electronic warfare analysis for Naval Aviation Enterprise, September 2024), Intuitive Research and Technology Corporation (systems engineering and modular open systems architecture for Program Executive Office Aviation, January 2024), American Systems Corporation (software engineering for the Future Vertical Lift program, May 2023), Science Applications International Corporation (hardware-in-the-loop aviation systems engineering under GSA OASIS, August 2024), Mantech Advanced Systems International (RDT&E engineering services, October 2025), and Canvas II, LLC (programmatic support for the Aviation Mission Systems and Architecture program, September 2021). Across subcontractor work, JHNA delivers systems engineering, software sustainment, JCIDS documentation, logistics robotics expertise, and program management analysis.

JHNA operates through a subsidiary, Technology Security Associates, Inc., a Subchapter S corporation. The Service Contract Inventory dataset captures minimal federal services activity — $0 invoiced revenue on prime contracts across FY2022 and FY2024, with roughly 4.8 to 6.0 FTEs delivered across prime and subcontractor SCI-reportable work. This sparse SCI footprint reflects JHNA's emphasis on large IDIQs and government supply schedule positions that generate task order work not yet captured in the SCI timeline, as well as the vendor's substantial subcontractor role where SCI reports the prime contractor's invoicing rather than JHNA's sub-tier revenue. On the GSA Multiple Award Schedule, JHNA's labor portfolio spans entry-level project administrators and software engineers through senior IT subject matter experts and architects, with no security-cleared roles offered under that vehicle. Recent activity shows growth from 2 awards in 2022 to 9 in 2024, though the 2025 year-to-date count (7 awards) remains early in the fiscal cycle.
