Ensco Inc.

Ensco Inc., doing business as Enscohi, operates as a for-profit technology company headquartered in Vienna, Virginia, delivering engineering, science, and advanced technology solutions to federal agencies primarily as a prime contractor (98% of recent awards) across transportation safety research, aerospace systems, space situational awareness, and national security domains. The company competes predominantly in full-and-open federal procurements with no SBA set-aside posture at the enterprise level, though it qualifies as a small business under multiple federal vehicles and holds several total small business set-aside positions on individual IDIQs.

Ensco's customer concentration is heavily weighted toward civilian transportation and defense space missions. The Federal Railroad Administration dominates the customer portfolio with 369 awards worth $1.26 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 2032. Air Force Space Command follows with 170 awards valued at $507.2 million combined potential value, including an $84.2 million single-award IDIQ for modeling, software, and engineering support at the Air Force Technical Application Center through September 2032. The top five customer agencies account for 78% of awards across the portfolio. Ensco also recently entered the Missile Defense Agency's $151 billion SHIELD program on December 29, 2025, as one of multiple awardees, though that vehicle carries a placeholder ceiling with no specified contract value cap.

Ensco holds position on multiple government-wide and agency-specific vehicle platforms. On the GSA FAS OASIS+ vehicles, the company is a small-business awardee under the Total Small Business set-aside IDIQ (awarded December 19, 2024, with $999.999 billion placeholder ceiling through December 18, 2029) and an unrestricted multiple-award awardee under OASIS+ Unrestricted (awarded December 17, 2024, with placeholder ceiling through December 16, 2029). The company also holds a ProTech 2.0 - Satellite Domain multiple-award IDIQ with NOAA ($8 billion ceiling, total small business set-aside, through June 29, 2028) and a Transportation Human Factors Research, Development, and Program Evaluation IDIQ with the Immediate Office of the Secretary of Transportation ($2.5 million, through December 16, 2025). At the agency level, Ensco's largest vehicles include the FRA Transportation Technology Center master IDV (89 task orders worth $71.5 million), an Air Force Space Command FA702217D0009 vehicle (97 task orders, $99.8 million), and an indefinite-delivery contract DTFR5310D00002 (51 task orders, $26 million).

Capability framing across Ensco's recent awards spans rail safety research and infrastructure testing, including wheel and rail profile optimization, switches and crossings model development, tank car safety research, track inspection technology, and safety training program development for rail operators. For Air Force Space Command, the company delivers modeling, software engineering, and technical analysis in support of persistent surveillance programs, meteorological modeling, environmental simulation, acoustic data labeling, sensor placement optimization, and space situational awareness missions performed at Patrick Space Force Base and Melbourne, Florida. Recent representative prime awards include a $68.3 million Air Force Space and Missile Systems Center delivery order for system engineering and integration support to the Launch and Test Range System (May 2023), a $34.8 million Air Force definitive contract for defensive cyber operations space systems engineering and integration (May 2023), a $100.2 million FRA definitive contract for Automated Track Inspection Program services (April 2023), a $9.1 million Air Force Space Command delivery order for data discovery and data labeling in support of persistent surveillance (September 2025), and a $4.68 million FRA delivery order for development of rental measurement technologies (September 2026). TSA has awarded Ensco a $2.4 million delivery order for surface transportation security training and course development (May 2023) and a $944,100 delivery order for surface operations investigator training (April 2026).

Activity trajectory shows modest decline from 31 awards in 2022 to 22 awards year-to-date in 2026, reflecting a transition toward larger, higher-value delivery orders and IDIQs rather than small task-order accumulation. The recompete window through October 2027 exposes 41 awards worth $175 million in combined potential value, concentrated in FRA transportation research and facility management work. Service Contract Inventory data shows Ensco invoiced $229.4 million across SCI-reportable service contracts from FY2022 through FY2025 (prime records), with FY2023 peak invoicing of $71 million across 188 FTEs on federal service contracts. Government-paid median hourly rates on those invoiced contracts ran $173.92 per hour, ranging from zero-dollar fixed-price work to rates as high as $574.50 per hour for senior technical roles. FY2024 and FY2025 show workforce modulation to 133–144 FTEs respectively, with invoiced amounts of $53 million to $59 million. Across SCI-reportable prime contracts, subcontractors supplied approximately 7% of total contractor hours, with 80 named subcontractors engaged over the period, indicating Ensco primarily self-performs its federal service delivery.

Ensco operates as a subcontractor on defense and aerospace programs under larger primes including HII Mission Technologies (propulsion and cyber capabilities analyses for Air Force Life Cycle Management Center, research collaboration for Air Force Research Laboratory), Modern Technology Solutions (Battle Management Command Control Communications sustainment technical support), Linquest Corporation (military satellite communications systems engineering), Radiance Technologies (cyber operations suite development and Zero Trust Architecture research), and Accenture Federal Services (networks procurement support). These sub-relationships reflect Ensco's capability in systems engineering, cybersecurity, and technical analysis supporting primes anchored in defense space and cyber domains.

Corporate structure includes named subsidiaries Redvox Inc., Ensco Avionics Inc., Idata Visual Systems Inc., and multiple similarly-named Ensco Inc. entities, though the source does not specify subsidiary-level capability differentiation or operational autonomy. GSA Schedule labor portfolio spans 41 categories priced from $71.13 per hour (technician) through $402.92 per hour (program manager), with no security-cleared roles offered on the schedule. The company's top NAICS codes by award count are Engineering Services (188 awards), Other Computer Related Services (182 awards), and Research and Development in the Physical, Engineering, and Life Sciences (160 awards), with PSC concentration in professional engineering and technical support, transportation R&D, and general science and technology R&D services.
