Technology Service Corp

Technology Service Corp, doing business as TSC, is a for-profit defense technology and engineering contractor headquartered in Arlington, Virginia, that delivers advanced sensor systems, radio frequency seeker technology, modeling and simulation, and specialized aerospace platforms to the Department of Defense and Department of the Navy as a prime contractor on 87% of recent awards and as a subcontractor to Lockheed Martin, Northrop Grumman, Torch Technologies, and other major primes. TSC operates across the full and open competitive landscape without set-aside designations, competing primarily on technical merit for research and development, systems engineering, and specialized defense technology work.

TSC's customer concentration is heavily weighted toward defense and intelligence agencies. The Department of the Air Force dominates by dollar value—158 awards carry $46.14 billion in combined potential value—while the Department of the Navy leads by award count (435 awards, $15 million potential value), though that count reflects higher volume of smaller task orders. The Department of the Army Materiel Command Army Contracting Command Aberdeen Proving Ground anchors $37.41 billion across 12 awards, and U.S. Special Operations Command (USSOCOM) carries $925.6 million across 21 awards. Together, these top customers account for 98% of combined potential value. NAICS concentration runs to engineering services (239 awards), research and development in physical and engineering sciences (290 awards across two related codes), and sensor and system manufacturing (24 awards).

TSC's portfolio includes multiple large indefinite delivery vehicles. A $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ with the Missile Defense Agency (awarded December 2025) carries advanced research, prototyping, systems engineering, and weapon design across air, missile, space, cyber, and hybrid domains. A $400 million single-award USSOCOM indefinite delivery contract (awarded September 2025) funds long-endurance aircraft intelligence, surveillance, and reconnaissance services through August 2030. An Office of Naval Research single-award indefinite delivery for research, development, and engineering support for specialized aerospace systems carries a $95 million ceiling (awarded March 2022, set-aside for total small business). On the Air Force side, a $20 million single-award low-cost air-to-ground radio frequency seeker IDIQ (awarded April 2024, cost-plus-fixed-fee) has issued three delivery orders valued at $4.34 million, $12.62 million, and $3.39 million respectively for seeker development, prototyping, and testing. The Eglin Wide Agile Acquisition Contract (EWAAC) on-ramp IV (awarded March 2025, multiple-award, $46 billion program ceiling) supports ammunition and munitions work through September 2031. TSC also holds a $243.9 million Office of Naval Research multiple-award indefinite delivery for tactical electronic warfare and combat systems research (awarded March 2025, total small business set-aside).

Recent named prime work includes a $96.49 million Air Force delivery order (September 2025) for ISR Service FY2025 long-endurance aircraft operations, mission crew services, and logistics across 12 months, subcontracting mission support to Claron Technical Services (women-owned small business), Titan Echelon (service-disabled veteran-owned small business), and Aevex Aerospace. A $123.9 million Office of Naval Research definitive contract (May 2022) for PANTHER research and development in high-power radio frequency signal generation and implementation, cost-plus-fixed-fee, runs through May 2027, with K&L Microwave engaged as a subcontractor on the Longbow Project component. A $74.9 million Naval Supply Systems Command delivery order (January 2024) under Seaport-NXG for systems engineering support to Naval Surface Warfare Center Dahlgren funds combat systems engineering trades and analyses through August 2028, with subcontractors including Patricio Enterprises (minority-owned, service-disabled veteran-owned small business), Simventions Inc., and Valkyrie Enterprises LLC. A $66.8 million Naval Sea Systems Command delivery order (June 2024) under Seaport-NXG for sensor systems engineering and technical support, cost-plus-fixed-fee, runs through November 2029. A $35 million Office of the Secretary of Defense Other Transaction Agreement (March 2026) for procurement of a Tuna Seeker, administrative modification incorporating DD254 and duty-free entry clause, carries an ultimate completion date of March 2027. TSC also holds a $21.5 million Naval Air Warfare Center Small Business Innovation Research Phase III definitive contract (September 2025) for Sea Dragon ISR Services through February 2029, firm fixed price.

Activity has accelerated over the past three years—25 awards in 2022 to 105 in 2024, with 47 awards in 2025 and 8 in the first nine months of 2026—signaling strong pipeline momentum, though the recent award count reflects the large volume of task orders issued against standing IDIQs rather than new vehicle awards. Twelve awards with combined potential value $472.5 million face ultimate completion inside the next twenty-four months and represent recompete exposure.

SCI-reportable invoiced revenue captures $11.5 million across FY2024 on a subset of the vendor's federal services portfolio; in that fiscal year, TSC delivered roughly 45.9 FTEs on contracts above the $150,000 reporting threshold. Government-paid hourly rates for prime SCI contracts run around a median of $107.74 per hour, with senior labor pricing toward $219.60 per hour. Across SCI-reportable prime contracts, subcontractors perform roughly 3% of contractor hours, indicating TSC builds most of its delivery teams in-house. On the sub side, TSC performs specialized sensor, antenna, and engineering design work for Torch Technologies (multiple awards for missile guidance and seeker technical support across Combat Capabilities Development Command Aviation and Missile Center), Applied Research Solutions (mission autonomy for air and space systems R&D, multiple awards since June 2022), Lockheed Martin (guided munitions systems redesign, O&M maintenance for licensed platforms), Science Applications International Corporation (surveillance and broadcast services support to the FAA, multiple awards across FY2024), L3Harris Interstate Electronics Corporation (flight test instrumentation support and radar system work, multiple awards), Northrop Grumman Systems Corporation (long-range radar system engineering support, product support, and logistics, multiple awards from September 2025), and others. This subcontractor posture—wide engagement across major defense primes on specialized sensing and RF technology work—positions TSC as a highly sought technical resource for flagship programs rather than as a feeder shop.

The vendor's subsidiary structure lists 17 named entities, including Praxis Products LLC and Avwatch Inc., though the source does not detail subsidiary capabilities or consolidation strategy. Activity trajectory and recompete cliff indicators—particularly the $151 billion SHIELD and $400 million USSOCOM vehicles awarded in late 2025—suggest TSC is anchored on multi-year, high-ceiling contracts that will drive task-order volume through 2027–2030.
