Hamilton Associates Inc.

Hamilton Associates Inc., operating its Air Techniques International (ATI) Division and doing business as Air Techniques International, is a small business manufacturer of optical detection technology and sensors that supplies calibration, maintenance, and repair services for CBRN defense equipment to the Department of Defense as a prime contractor on 520 of its 524 recent federal awards. The vendor competes full-and-open; no set-asides characterize its prime footprint, though it has received four total small business set-aside awards (one $1 million JSMLT upgrade BPA call, one $95 thousand M46 mask leak tester purchase order, and two smaller BPA calls under $14 thousand combined). Hamilton Associates is a for-profit Subchapter S corporation headquartered in Owings Mills, Maryland, with primary NAICS in analytical laboratory instrument manufacturing and other electronic and precision equipment repair and maintenance.

The vendor's capability portfolio centers on calibration and repair of aerosol photometers, Joint Service Modular Laser Testbed (JSMLT) systems, gas mask and protective mask leak testers, and related optical detection equipment serving CBRN defense programs across Army, Navy, and Air Force installations. Representative work includes a $135.9 thousand Naval Sea Systems Command purchase order for photometers for nuclear applications (August 2024), a $1 million Army Joint PEO Chemical and Biological Defense BPA call for JSMLT upgrades (November 2021), a $95.1 thousand Air Force small business set-aside purchase order for M46 mask leak testers (June 2023), a $30.9 thousand Air Force purchase order for JSMLT upgrades (September 2023), and an ongoing $28.7 thousand Army Research Development and Engineering Command preventative maintenance contract for photometers and TDA-100 testers at Aberdeen Proving Ground running through September 2026.

Customer concentration is extreme and Army-anchored. The top five customer entities account for 59% of recent awards by count: the Department of the Army Acquisition Support Center PMPEO PBUSE (120 awards, $18.1 million), Naval Sea Systems Command (65 awards, $758 thousand), the Army Materiel Command Research Development and Engineering Command (55 awards, $25.8 million), the Department of the Army general (37 awards, $3 thousand), and Army Contracting Command Aberdeen Proving Ground (32 awards, $7.7 million). The top five by potential value represent 30% of combined dollars, led by Army RD&E Command at $25.8 million. The Army, Navy, Air Force, and Marine Corps account for the overwhelming majority of awards; the vendor has served 55 distinct customer agencies but concentrates its delivery in three defense organizations.

Hamilton Associates holds positions on five named parent vehicles. The Indefinite Delivery Contract W911QY09D0008 carries 122 task orders valued at $2.5 million combined; the Blanket Purchase Agreement W911QY17A0010 has 62 task orders at $10.5 million combined; the IDC W911SR05D0012 has 31 task orders at $27.2 million combined (the largest single vehicle); the GSA Federal Supply Schedule GS24F1099B holds 33 task orders at $136 thousand; and the Information Analysis Center Multiple-Award Contract carries 3 task orders. These vehicles are primarily single- or limited-award structures anchored to Army procurement offices, not government-wide GWACs. The vendor also holds a single-award Indefinite Delivery Contract from Naval Sea Systems Command (valued at $64.8 thousand with ultimate completion September 2027) for calibration of up to twenty photometers annually, with one $13.6 thousand delivery order issued September 2025.

Activity has remained consistent across the past five years (2022–2026), ranging from six to nine awards annually, with minimal recompete exposure: only four awards totaling $195 thousand face ultimate completion within the next twenty-four months. Total awards across the vendor's entire federal footprint number 524 with combined potential value of $197 million and combined obligations of $83.1 million (42% of potential). SCI-reportable invoicing shows minimal service-contract-level activity: $1.3 million invoiced in FY2023 across 2.4 contractor FTEs, with $0 reported in FY2022 and FY2024. Government-paid hourly rates on SCI-reportable contracts (FY2023 only) ran at a flat $258.97 per hour across all percentiles, reflecting a single large service contract. The vendor subcontracts to other primes in 1% of its award footprint (four sub awards). Named prime contractors include Battelle Memorial Institute (three sub awards for CBRN defense testing, analytics, and JSMLT mask tester maintenance since January 2022) and Fluor Marine Propulsion LLC (one December 2023 sub award for naval nuclear laboratory photometer work).

The vendor's footprint reflects a specialized, equipment-centric supplier model: 99% of recent awards are primes (predominantly firm fixed-price purchase orders and BPA calls in the $1.5 thousand to $1 million range), manufacturing and calibration-focused work with minimal services content, and highly concentrated Army exposure centered on JSMLT programs and photometer support across Army RD&E Command and Joint PEO Chemical and Biological Defense. This is a niche defense vendor with deep Army entanglement and Navy secondary exposure, competing without set-aside protection on a broad base of recurring maintenance and equipment-supply orders.
