About Equator Corporation
Equator Corporation, a veteran-owned for-profit Subchapter S corporation headquartered in Leesburg, Virginia, operates predominantly as a subcontractor (79% of recent awards) across defense test and evaluation, systems engineering, and facility support services, with emerging prime positions on the Missile Defense Agency's SHIELD IDIQ and GSA's OASIS+ Small Business vehicle.
Equator competes full-and-open without set-aside designation on its prime work. The company holds two significant IDIQs awarded in 2025: the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program under the Missile Defense Agency with a $151 billion ceiling and ultimate completion date of December 28, 2035, and a multiple-award position on GSA's OASIS+ Total Small Business set-aside with performance spanning all seven functional domains (Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental Services, Facilities, and Logistics) through April 14, 2030. The inaugural SHIELD task order, awarded December 29, 2025, carries a $500 ceiling for work performed at MDA's facility in Huntsville, Alabama. Recent prime work also includes a $25,000 definitive contract with the Office of Administrative Services Procurement Management Branch for OVRWATCH software license and maintenance renewal, completion scheduled May 26, 2030.
Equator's customer base concentrates heavily in defense test and evaluation. The Defense Information Systems Agency leads by volume with 11 awards, followed by NASA's Goddard Space Flight Center with 8 awards, and the Office of the Secretary of Defense with 3 awards; these three agencies account for 90% of the award count. Work under the Indefinite Delivery Contract HC102823D0002 (an 11-task-order vehicle at DISA) anchors the DISA relationship. The top NAICS categories reflect this portfolio: Testing Laboratories and Services (11 awards), Commercial and Institutional Building Construction (8 awards, driven by Goddard facility work), and Research and Development in the Physical, Engineering, and Life Sciences (5 awards).
On the subcontractor side, Equator primarily delivers test and evaluation support and systems engineering to Agile Defense LLC on multiple JITC task orders supporting operational effectiveness testing for programs including JOMIS (Joint Ordnance Management Information System) and DHMSM, with task orders running through 2025. Equator also subs to Ptsi Managed Services Inc. on facility design and construction services at NASA's Goddard Space Flight Center, to Parsons Government Services Inc. on TEAMS-NEXT missile defense systems engineering, and to Radiance Technologies Inc. on systems engineering and technical assistance for the Army Rapid Capabilities and Critical Technologies Office. A $217,000 purchase order as subcontractor to Ptsi Managed Services for OVRWATCH P1300 cybersecurity unit systems in support of USDA Food Safety and Inspection Service (performance in Stafford, Virginia, completion August 31, 2024) represents prior facility-hardening work.
SCI-reported data capture is minimal — 2 records in FY2022 spanning only subcontract labor, showing 10.3 FTEs delivered under named subcontracts. This reflects the classified and defense test-focused nature of much of Equator's work, which typically falls outside SCI's $150,000 threshold reporting scope or involves security-restricted contracts not disclosed in public inventories. Combined obligated dollars across all awards ($40 million) substantially exceed combined potential value ($340 thousand), indicating significant contract modifications and funded task order growth, particularly on the recurring DISA and Goddard platforms.
