The Captor Corporation

The Captor Corporation, a veteran-owned small business manufacturer headquartered in Tipp City, Ohio, supplies high-precision electromagnetic interference and radio frequency filters to the Department of Defense as a prime contractor (84% of awards) and as a subcontractor to major defense primes. The company is structured as a for-profit Subchapter S corporation and competes predominantly under full-and-open and small-business set-aside designations, with total small business set-asides recurring across roughly 30% of its prime footprint.

The Captor Corporation manufactures radio frequency filters, band pass filters, electromagnetic interference filters, and transient protection modules for military communication, avionics, and electronic systems. Representative prime work includes a $799,968 purchase order from Naval Supply Systems Command awarded in June 2025 for radio frequency filters; a $405,900 total small business set-aside purchase order from Defense Logistics Agency Land and Maritime in July 2022 for 44 units of radio frequency filters (NSN 5915012559540); a $241,125 purchase order from Naval Sea Systems Command in September 2022 for spike suppression filters; and a $124,620 total small business set-aside purchase order from Army Test and Evaluation Command in September 2022 for EMI filters. Recent subcontract work includes EMI and filter assemblies supplied to Northrop Grumman for the Integrated Battle Command System (IBCS) hardware production, filter and multiplexer components to Raytheon for PATRIOT systems spare parts and international programs, and EMI filter assemblies to Lockheed Martin for F-16 infrared search and track systems and B-1B Lancer avionics.

Customer concentration is extreme. Defense Logistics Agency Land and Maritime dominates both volume and dollars, accounting for 469 of 609 prime awards (77% by count) with $10 million in combined potential value. Naval Supply Systems Command ranks second with 25 awards and $2.2 million in potential value; Naval Sea Systems Command holds 19 awards totaling $358 thousand; and DLA Aviation maintains 16 awards valued at $274 thousand. These five customer entities account for 96% of the vendor's combined potential value. The vendor holds five active single-award indefinite delivery contracts with DLA Land and Maritime, each valued at $350,000, awarded between December 2025 and April 2026 for various radio frequency filter stock numbers (NSN 5915012559541, 5915012962202, 5915012647869, 5915012583965, 5915012568537). One additional $250,000 single-award IDC with DLA Aviation for standoff insulators expired in July 2024.

Activity has grown sharply. Awards counted 29 in 2022, 33 in 2023, 47 in 2024, and 107 in 2025, with 15 awards recorded through mid-2026. Combined potential value stands at $13.6 million against $47.4 million in obligated dollars, indicating that the vendor invoices and completes work faster than new award ceilings are posted. Only five awards with combined potential value of $184 thousand face ultimate completion within the next twenty-four months, creating minimal recompete cliff risk in that window. The vendor has shipped work continuously to DLA since at least 2021 and holds established teaming relationships with Northrop Grumman (primarily IBCS hardware components), Raytheon (PATRIOT and international radar filters), Lockheed Martin (F-16 and B-1B filter assemblies), L3Harris Technologies (countermeasures and sustainment EMI filters), and Science Applications International Corporation (GMASS EMI filters). The Captor Corporation's footprint is almost entirely filter manufacturing — 583 of 789 total awards (74%) fall under PSC 59 (Filters and Networks), with 274 awards under NAICS 334419 (Other Electronic Component Manufacturing) and 107 under radio and television broadcasting and wireless communications equipment manufacturing, confirming a focused supply-chain role as a specialized component manufacturer rather than a systems integrator or services provider.
