Technology Service Corp

Technology Service Corp, doing business as TSC, is an Arlington, Virginia-based high-technology engineering consulting firm that delivers advanced sensor development, radar systems, radio frequency seeker technology, intelligence-surveillance-reconnaissance (ISR) services, spacecraft engineering, systems integration, and specialized aerospace platform support to the Department of Defense, U.S. Special Operations Command, and naval research agencies as a prime contractor on 87% of its recent awards and as a subcontractor to major defense primes on 13%. The company competes predominantly in full-and-open procurements with no recurring set-aside posture; its corporate structure includes 17 named subsidiaries spanning sensor manufacturers (Polyphase Microwave Inc., Pivc LLC), aerospace systems integrators, and specialized defense services entities, positioning TSC as a diversified capability provider rather than a single-service vendor.

TSC's federal footprint spans 1,451 awards since 1980, with a combined potential value of $87.71 billion and $1.8 billion in obligated dollars as of mid-2026. The vendor's customer concentration is heavily weighted toward defense and naval customers. The Department of the Navy leads by award count with 435 awards carrying $15 million in combined potential value, though this concentration reflects the breadth of smaller orders. The Department of the Air Force Materiel Command Research Laboratory places 135 awards valued at $445.9 million combined. By potential value, the Army Materiel Command at Aberdeen Proving Ground dominates with 12 awards valued at $37.41 billion—a single-customer concentration that likely reflects one or two very large IDIQ vehicles. U.S. Special Operations Command (21 awards, $925.6 million) and the Office of Naval Research (33 awards, $810 million) anchor major capability areas in ISR and aerospace systems development. These five customer entities account for 46% of TSC's combined potential value across the portfolio, signaling strong institutional relationships with core defense R&D and acquisition organizations.

TSC holds positions on multiple large government-wide and agency-wide vehicles. The company operates under five named parent IDIQs and schedules: the Multiple Award Schedule with 65 task orders ($20.3 million), Federal Supply Schedule GS23F0032L with 50 task orders ($25.2 million), and three large Indefinite Delivery Contracts (N0016492D0001 with 51 task orders, N0016488D0049 with 39 task orders, N0016496D0002 with 33 task orders). Most significantly, TSC was awarded a $151 billion multiple-award Indefinite Delivery Contract on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) vehicle by the Missile Defense Agency on December 29, 2025, positioning the company to compete across multi-domain defense system R&D, prototyping, systems engineering, and production efforts. TSC also holds single-award IDCs with USSOCOM ($400 million for long-endurance aircraft ISR, September 1, 2025, through August 31, 2030) and a previously mentioned $154.4 million single-award SBIR Phase III vehicle with USSOCOM for unmanned aviation and aerospace solutions. The Office of Naval Research RDES-SAS IDC ($95 million, single-award, total small business set-aside through March 6, 2027) and the PANTHER research and development contract ($123.9 million, total small business set-aside, through May 10, 2027) demonstrate sustained access to Navy science and technology funding.

Recent activity shows growth into 2024 and 2025. Award volume moved from 25 per year in 2022 to a peak of 105 in 2024, declining to 47 in 2025 and 5 in 2026 (year-to-date), reflecting a typical pattern of bulk IDIQ issuances followed by task-order disbursement. Eleven awards with combined potential value of $327.3 million reach ultimate completion in the next twenty-four months, creating recompete exposure for TSC and opportunity for competitors across naval systems engineering, ISR services, and advanced electronics platforms.

Capability portfolio centers on radio frequency and sensor system development — concrete recent awards include a $63.46 million ISR Service delivery order from the Air Force (September 1, 2025) covering long-endurance aircraft operations, mission crew services, maintenance, and technology insertion; a $21.5 million Sea Dragon ISR Services contract from Naval Air Warfare Center under SBIR Phase III (September 25, 2025); a $74.9 million Sensor Systems Engineering and Technical Support order from Naval Sea Systems Command under Seaport-NXG (January 31, 2024) for systems engineering, modeling, hardware design, and signal processing; a $29.7 million Tactical Combat and Electronic Warfare Systems Research delivery order from Office of Naval Research (July 1, 2025) for digital computer modeling and simulation; and a $123.9 million PANTHER research and development contract with ONR (May 11, 2022) for radio frequency signal generation and atmospheric research applications. These awards show TSC's concentration in advanced development and applied research rather than production, with work spanning Arlington, Virginia; Washington, DC; naval warfare centers; and test ranges. Top NAICS concentration runs to Engineering Services (239 awards), R&D in Physical, Engineering, and Life Sciences (176 awards), and System and Instrument Manufacturing (23 awards), with PSC codes weighted heavily toward R&D defense other (115 awards) and professional engineering support (184 awards).

On Service Contract Inventory, TSC reported $11.5 million in invoiced federal service-contract revenue across FY2024 — the only fiscal year with material SCI activity in the source window — supporting 45.9 full-time equivalents at a median government-paid rate of $107.74 per hour, with senior labor pricing reaching the 90th percentile of $219.60 per hour and entry-level support at approximately $30.19 per hour. Across SCI-reportable prime contracts, subcontractors account for 4% of total contractor hours, indicating TSC builds most of its delivery teams internally. The vendor names 11 distinct subcontractors in SCI records; on broader federal contracts, TSC subcontracts heavily to specialized defense primes including Torch Technologies Inc. (multiple technical and engineering support task orders across Army Combat Capabilities Development Command platforms), Northrop Grumman Systems (Long Range Radar sustainment and engineering support), Leidos Inc. (infrared and RF systems R&D for naval systems), L3Harris Interstate Electronics (flight test instrumentation and radar backend electronics), Lockheed Martin (GMLRS production, CP development, TSC license support), Applied Research Solutions Inc. (mission autonomy for air and space systems), and others including Booz Allen Hamilton, Johns Hopkins University Applied Physics Laboratory, and Salient CRGT. This pattern reflects TSC's role as a systems integrator and prime on large IDIQ vehicles that flex subcontractors to meet specialized technical requirements rather than as a dedicated subcontractor to a single prime, though the recurrence of certain primes (Torch, Northrop, Leidos) suggests established teaming relationships for Army and Navy technical development work.

TSC has operated as a federal contractor since January 2002, holding 1,264 prime awards and 187 sub-awards across defense, special operations, naval research, and air force R&D portfolios. The company's sustained access to major IDIQ vehicles, its specialized expertise in RF and sensor technologies, and its scale (76 FTEs on SCI contracts in FY2024, with a much larger enterprise footprint evidenced by the 1,451-award portfolio) position it as a capable prime contractor for advanced defense technology acquisition and a sought subcontractor for technical depth on complex integration efforts.
