About Atac
Atac, a small business headquartered in Santa Clara, California, provides aviation analysis, simulation, systems engineering, and technical services to federal agencies across defense and civilian domains. Atac operates almost exclusively as a prime contractor (100% of recent awards) and competes predominantly in full-and-open procurements, though select awards carry partial small business set-asides. The vendor holds a dominant position with the Federal Aviation Administration, anchored by two large indefinite-delivery vehicles that underpin the majority of recent activity.
Atac's customer concentration is extreme and FAA-centric. The Federal Aviation Administration accounts for 79 percent of awards by count and 68 percent of combined potential value across the top-five customers. The split between two FAA ranking tiers reveals the structure: FAA Headquarters dominates with 297 awards valued at $5.38 billion; FAA's Aeronautical Center contributes a secondary $2.3 billion across seven awards. These two FAA lines alone represent the vast bulk of the vendor's recent pipeline. The Navy (141 awards, $51 thousand combined value) and NASA's Shared Services Center (34 awards, $12.2 million) are distant followers, signaling that Atac's defense and space work is either small-dollar or categorized elsewhere in the portfolio.
Atac's capability portfolio centers on aviation-specific technical services: Performance Data Analysis and Reporting System (PDARS) operations, sustainment, and modernization; Systems Engineering and Technical Innovative Solutions (SETIS) research and development; environmental assessment and airspace modernization analysis; safety analysis for rotorcraft and emerging aircraft; and data analytics for air traffic management. Representative prime work includes the $81.8 million single-award PDARS II Indefinite Delivery Contract (February 2021, FAA, ultimate completion December 2026) for core system operations, quality control, maintenance, security, and data analysis; the $2.268 billion single-award SETIS Indefinite Delivery Contract (June 2022, FAA, through June 2028) for research, service analysis, and strategic planning across multiple aviation domains; and a $43.9 million partial small business delivery order (November 2023, FAA) for rotorcraft, vertical flight, eVTOL, autonomous aircraft, and unmanned aircraft safety analysis and testing. Atac also executes NASA Small Business Innovation Research (SBIR) Phase II and Phase III contracts, including a $749.9 million SBIR Phase II for low-altitude wind hazard alerting and a $634.8 million SBIR Phase III for UAM noise integration testing.
The vendor holds two major FAA indefinite-delivery vehicles that serve as the parent for most task-order activity. The PDARS II IDC, valued at $81.8 million (single award, non-set-aside), supports core system operations and regional service center work through time-and-materials delivery orders. The SETIS IDC, valued at $2.268 billion (partial small business set-aside, single award), generates task orders across rotorcraft safety analysis, environmental assessment, weather systems, and trajectory modeling. Five additional IDCs—DTFAWA11D00038 ($128.1 million across 88 task orders), DTFAWA11D00019 ($219.3 million across 56 task orders), 693KA921D00007 ($53.7 million across 60 task orders), and DTFAWA17D00020 ($38.8 million across 53 task orders)—represent older vehicles carrying sustained delivery-order volume. A seventh vehicle, DTFAAC05D00075, carries $5.85 billion in combined potential value across 26 task orders, indicating a high-ceiling IDC likely supporting long-term FAA initiatives.
Activity has remained relatively stable year over year—18 awards in 2022 declining to 11 in 2025 and 5 in the first five months of 2026. Twelve awards (combined potential value $65.5 million) face ultimate completion within the next twenty-four months, presenting recompete exposure concentrated in the FAA's PDARS and weather-related NAS support portfolios. The vendor has three sub-awards on record: environmental impact statement work under HDR Environmental as prime, technical services at NASA Ames and Langley facilities (prime contractor unnamed), and analytical support to UC Regents on a NASA grant (December 2024) focused on National Airspace System disruption analysis and student internship programs. Sub-engagement is minimal—SCI data shows zero percent sub-hours share across prime contracts, and only 2 of 140 SCI records are named-sub positions.
The SCI dataset shows no invoiced revenue across FY2022–FY2024, with FTE trajectories minimal (0.8 FTEs in FY2022, 0.0 in FY2023, 0.5 in FY2024 across 47–52 prime records per year). This disconnect signals that Atac's federal contracting is driven by capital-intensive systems and materials work (equipment updates, software integration, modeling platforms), research awards, and fixed-price engineering tasks—all of which fall outside the $150,000 SCI reporting threshold or land in goods and products categories excluded from SCI. The source data confirms Atac has been registered with SAM since March 2002 and is described as a strategic technical partner to the FAA for over two decades.
