A-P-T Research, Inc.

A-P-T Research, Inc., doing business as Apt Research, is a small, employee-owned engineering and technical services firm headquartered in Huntsville, Alabama, that delivers safety analysis, systems engineering, software assurance, and risk assessment services to federal agencies primarily as a prime contractor (90% of recent awards) across defense, civilian, and space portfolios. The vendor competes full-and-open on most work and holds positions on both total small business set-aside vehicles and unrestricted governmentwide IDIQs, reflecting a diversified competitive posture without a single dominant set-aside category.

A-P-T Research's core capability portfolio centers on explosives safety analysis, explosion effects and consequences modeling, blast-resistant structural engineering, and mission assurance support for complex defense and space systems. Representative prime work includes a $60.6 million delivery order from the Missile Defense Agency under the OASIS+ Total Small Business IDIQ for safety and mission assurance support to the Quality, Safety and Mission Assurance Directorate through December 2031; a $38.7 million definitive contract with NASA Kennedy Space Center for Safety and Mission Assurance Support Services (SMASS IV) running through January 2028, which generated $21 million in government-invoiced labor through FY2025 across 128.6 FTEs; a $1.1 million delivery order from Naval Facilities Engineering Command for Explosive Containment Module testing and gas pressure rise modeling under total small business set-aside; a $1.7 million delivery order from the Army Corps of Engineers Huntsville Engineering and Support Center for cradle-to-grave project management support worldwide through March 2031 under GSA Multiple Award Schedule; and recurring $22,000–$250,000 purchase orders and deliverables with the Bureau of Alcohol, Tobacco, Firearms and Explosives for maintenance, training, and software upgrades to proprietary explosives safety tools (Explosive Decision Aid, IMESAFR platforms). GSA Schedule labor rates span $44.40 to $386.39 per hour across 51 categories, ranging from junior business operations analysts through subject matter experts with 30 years' experience, with no security clearance positions offered.

Customer concentration is fragmented across defense, civilian, and space agencies. The top five customers by award count account for 49% of all awards: the Bureau of Alcohol, Tobacco, Firearms and Explosives (27 awards, $6.3 million combined potential value), Naval Facilities Engineering Command (26 awards, $27.8 million), Marine Corps (23 awards, $4.5 million), Army Corps of Engineers Huntsville (21 awards, $20.2 million), and NASA (14 awards). However, dollar concentration diverges sharply: the Department of the Navy Naval Sea Systems Command anchors the portfolio with 10 awards carrying $82.55 billion combined potential value — predominantly driven by small-dollar research and development contracts under the Small Business Innovation Research Program Phase II ($1.7 million definitive contract awarded November 2021). The Missile Defense Agency holds the second position with 13 awards and $368.7 million combined potential value. This concentration reflects a portfolio heavy in high-ceiling IDIQs with modest task-order utilization to date.

A-P-T Research holds seats on four primary contract vehicles: the OASIS+ Total Small Business Set-Aside IDIQ (awarded December 19, 2024, ceiling no dollar ceiling specified in the source through December 18, 2029); a $151 billion SHIELD (Scalable Homeland Innovative Enterprise Layered Defense) IDIQ under Missile Defense Agency (awarded December 29, 2025, full and open, no set-aside); a single-award $8.9 million Indefinite Delivery Contract with Naval Facilities Engineering Command for Blast Consequences and Explosion Effects work at Port Hueneme, California and subordinate NAVFAC sites (awarded June 3, 2026, total small business set-aside); and a $353.9 thousand single-award Blanket Purchase Agreement with Army Materiel Command Research Development and Engineering Command for test and evaluation R&D support (awarded December 27, 2022, no set-aside). The GSA Multiple Award Schedule carries 42 task orders valued at $25.6 million and represents the vendor's largest current transaction vehicle by order count.

Activity has remained steady over the past five years, averaging 8.6 awards annually (2022: 5; 2023: 11; 2024: 9; 2025: 12; 2026: 6 through mid-September). Three awards with combined potential value $39 million reach ultimate completion within the next twenty-four months, creating recompete exposure on modest-dollar maintenance and training orders with ATF and potential renewal opportunity on the NASA SMASS IV contract approaching its January 2028 completion date.

In its subcontractor role, A-P-T Research supports major aerospace and defense primes on systems engineering and safety analysis work. Recent sub-awards include: Space Launch System (SLS) Stages Production and Evolution Contract aerospace support to The Boeing Company (multiple sub-awards December 2023 through December 2025); Ground-Based Strategic Deterrent (GBSD) Engineering and Manufacturing Development services to Northrop Grumman Systems Corp (sub-awards May 2022, April 2025); system software lifecycle engineering to Science Applications International Corporation (October 2025); cargo helicopter life-cycle analysis to KBR Wyle Services (September 2025); and power and mobility R&D supporting Army Combat Capabilities Development Command to HII Mission Technologies Corp (September 2025). The vendor's sub footprint is concentrated in aerospace platforms and defense integration, complementing its prime work in mission assurance and safety analysis.

Across SCI-reportable prime service contracts (covering invoiced federal services above the $150,000 threshold), A-P-T Research generated $33.7 million in invoiced revenue from FY2022 through FY2025, with a declining trajectory: FY2022 $9.4 million across 62.3 FTEs, FY2023 $8.3 million across 51.5 FTEs, FY2024 $8 million across 50.1 FTEs, and FY2025 $8 million across 45.8 FTEs. Government-paid hourly rates on prime contracts averaged $78.88 per hour (median), ranging from $73.95 at the 10th percentile to $96.03 at the 90th percentile, consistent with engineering and systems support labor in the Huntsville, Alabama market. Across SCI-reportable prime contracts, subcontractors performed approximately 8% of total contractor hours, with seven named subcontractors identified across the FY2022–FY2025 window, indicating A-P-T Research maintains control of the majority of delivery through internal staff.

The vendor's award footprint spans 226 total awards (prime and sub combined) across 37 distinct federal agencies since 1993, with combined potential value of $83.16 billion, though only $274.2 million has been obligated to date (0% of combined potential value). Engineering Services NAICS 541330 dominates the portfolio with 90 awards, followed by Research and Development awards (24 awards) and Guided Missile and Space Vehicle Manufacturing (8 awards), reflecting deep specialization in defense and space systems engineering rather than broad service-provider positioning. Place of performance concentrates in Huntsville, Alabama (headquarters and primary facility) and Orlando, Florida (NASA Kennedy Space Center SMASS IV work), with subordinate performance locations at Naval Construction Battalion Center Port Hueneme, California for NAVFAC blast engineering work and worldwide support for Army Corps of Engineers projects.
