Ensco Inc.

Ensco Inc., doing business as Enscohi, is a for-profit technology company headquartered in Vienna, Virginia, that delivers engineering, science, and advanced technology solutions across transportation safety research, aerospace systems, space situational awareness, and national security domains as a prime contractor on 99% of its awards and holds positions on multiple government-wide and agency-specific indefinite-delivery vehicles.

The company operates as a largely unrestricted federal contractor, though a significant portion of its recent work carries total small business set-aside designations across the Federal Railroad Administration, Air Force Space Command, and other civilian and defense agencies. Ensco's subsidiary structure includes Ensco Avionics Inc. (self-certified small disadvantaged business), Redvox Inc., and Idata Visual Systems Inc., with redundant Ensco Inc. entities reflecting corporate registration patterns.

Ensco's federal footprint is heavily concentrated in transportation and aerospace: the Department of Transportation Federal Railroad Administration accounts for 362 awards worth $1.24 billion combined potential value, anchored by a $571.7 million single-award indefinite-delivery contract to manage and maintain the Transportation Technology Center in Pueblo, Colorado through September 2027. The Air Force Space Command ranks second with 165 awards worth $402.1 million, followed by the broader Department of the Air Force with 138 awards worth $38.3 million. These three customers account for 78% of award count. By dollars, the FRA dominates at $1.24 billion; the Air Force Space Command and its Space and Missile Systems Center together account for $732.6 million across 173 awards. Ensco holds a $151 billion ceiling on the newly awarded Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) contract with the Missile Defense Agency (December 2025) and sits on two OASIS+ vehicles (total small business and unrestricted) with ceilings of $999.999 billion each.

Concrete capability framing flows from its award history. At the FRA, Ensco performs rail safety research, vehicle testing, modeling and simulation of train dynamics, track inspection technology development (including LiDAR point cloud collection at grade crossings), continuous welded rail management, fire suppression technology evaluation, hazardous materials tank car research, locomotive compressor evaluation, and facility operations and maintenance at TTC. Representative FRA task orders include a $4.243 million cost-plus-fixed-fee delivery order for curved perturbation slab track installation (February 2025), a $749,996 order for modeling and validation of high-speed rail equipment (September 2025), a $620,663 order to evaluate fire suppression technologies and human factors impact (September 2025), and an $814,560 order to conduct compression testing of the Arrow III vehicle (September 2025). At Air Force Space Command, Ensco delivers modeling, software engineering, and technical analysis for the Air Force Technical Application Center (AFTAC), focusing on persistent surveillance programs, meteorological modeling, acoustic data labeling, and environmental simulation. Representative AFSC task orders include a $9.112 million order for data discovery and labeling supporting persistent surveillance (September 2025, no set-aside), multiple orders between $997,000 and $2.8 million for modeling and engineering support under the $84.245 million single-award small-business IDV (April 2025 through December 2025), and a $4.542 million order for persistence surveillance program modeling and software support (July 2024). Ensco also holds a $68.3 million delivery order with the Space and Missile Systems Center for system engineering and integration support of the Launch and Test Range System (May 2023) and a $34.8 million definitive contract with the Air Force for defensive cyber operations space systems engineering (May 2023).

On government-wide vehicles, Ensco's position spans the OASIS+ Total Small Business IDIQ ($999.999 billion ceiling, December 2024, performance through 2029) and OASIS+ Unrestricted IDIQ (same ceiling, December 2024, performance through 2029), both managed by the General Services Administration Federal Acquisition Service. The company also sits on the ProTech 2.0 - Satellite Domain IDIQ with NOAA ($8 billion ceiling, March 2023, total small business set-aside, performance through June 2028), though task order activity has been minimal—one $250 minimum-guarantee delivery order (March 2023).

Top parent vehicles by task-order volume are legacy air-force and transportation contracts. The indefinite-delivery contract FA702217D0009 (Air Force Space Command) carries 97 task orders valued at $99.8 million. The FRA's core management contract 693JJ621D000001 has generated 80 task orders worth $61.2 million. The Research Development Test and Evaluation (DTFR5310D00002) vehicle under the Department of Transportation shows 51 task orders valued at $26 million. FA702211D0005 (Air Force Space Command) supports 51 task orders worth $21.4 million. These vehicles reflect Ensco's sustained competitive position in both defense and civilian transportation modernization.

Service Contract Inventory reporting (FY2022–FY2024, covering contracts above $150,000) shows Ensco invoiced $170.3 million across 132 SCI-reportable records as prime contractor. FY2022 invoicing reached $46.3 million across 141 FTEs (contract-level aggregation); FY2023 peaked at $71 million across 188 FTEs; FY2024 declined to $53 million across 133 FTEs. Government-paid hourly rates on prime contracts ranged from a 10th percentile of $0.00 per hour (artifact of fixed-price and lump-sum arrangements) through a median of $171.15 per hour to a 90th percentile of $540.75 per hour, reflecting a broad labor spectrum from technical and engineering support through senior program management. Across SCI-reportable prime contracts, subcontractors performed an average of 9% of total contractor hours, with 72 named subcontractors identified across the portfolio. In FY2024, Ensco self-performed all reported hours on at least one full-scale tank car crash-testing contract (1,683 hours) without subcontractor engagement.

Ensco's teaming posture shows it primarily builds its own delivery teams. GSA Schedule labor categories span 41 unique roles priced between $71.13 per hour (Technician, high school education) and $402.92 per hour (Program Manager, bachelor's degree, ten years experience), with no security-cleared positions offered on the Schedule. Representative mid-range categories include Engineering Analyst 2 at $153.90 per hour and Senior Engineer/Scientist at $173.27 per hour, anchoring the company's technical depth in systems analysis and advanced engineering work.

Subcontractor relationships are selective and specialized. Recent sub-work identified includes engineering services to Linquest Corporation for military satellite communications systems engineering (February 2025), research collaboration and cyber security analysis to HII Mission Technologies Corp supporting the Air Force Research Laboratory Cyber Security division (March 2024), cyber operations and digital twin development to Radiance Technologies Inc. under the LIONS REACH program (March and January 2024), and battle management command-and-control technical support to Modern Technology Solutions Inc. (multiple task orders, December 2023–May 2024). University partnerships include a research collaboration with the University of Nebraska Board of Regents on self-referenced ultrasonic rail stress measurement (September 2025). This teaming pattern reflects Ensco's role as integrator and prime on large government contracts rather than as a feeder subcontractor to larger primes.

Activity trajectory shows 31 awards in 2022 scaling to 50 in 2023, then moderating to 42 in 2024 and 28 in 2025 (partial year through July 2026); seven awards have been recorded in 2026 to date. The recompete cliff window of the next twenty-four months reveals 38 awards with completion dates between July 2026 and July 2028, carrying combined potential value of $156.3 million. This represents meaningful recompete exposure concentrated in the FRA transportation research portfolio and AFSC modeling and engineering vehicle orders.

Ensco's award history reflects consistent customer concentration risk: the top five customers account for 78% of awards by count. By potential value, the FRA's $1.24 billion and combined AFSC entities' $732.6 million represent a substantial majority of Ensco's federal contract pipeline. The company's strength lies in sustained technical relationships with these agencies through multi-year indefinite-delivery vehicles and steady task-order issuance, but portfolio diversification beyond transportation and space technical intelligence remains limited in the source data.
