What GTMR, Inc. does
GTMR, Inc. (Global Technology and Management Resources, Inc.) is a veteran-owned defense contractor founded in 2004 and headquartered in Hollywood, Maryland, approximately ten miles from NAS Patuxent River. The company provides engineering, logistics, operational test and evaluation (OT&E), interactive electronic technical manual (IETM) development, technical illustrations, legacy data conversion, interactive training, and IPC-certified electronics training to US Department of Defense and aerospace customers. Its technology base centers on S1000D-compliant interactive electronic technical manuals, C4ISR and RF sensor systems engineering, lifecycle logistics management, and the proprietary Project THOR mobile multi-threat signal simulator developed at its Inyokern, California R&D facility for the F-35 Mission Systems Test organization. Customer engagements span NSWC Dahlgren (Weapons Control and Integration Department H), NAVAIR programs including EP-3E, P-8, Navy Special Mission Aircraft, Trident UAV and Multi-Intelligence Sensors Development, the US Coast Guard (HC-130J and HC-144B IETM), the Air Force Distributed Common Ground Stations, and JSF Mission Systems Test.
GTMR generates revenue through professional engineering and technical services delivered predominantly under prime contracts with US Government agencies and subcontracting relationships with major defense primes. The company sells through long-tenured government contract vehicles — GSA Multiple Award Schedule (contract GS-00F-080GA, through January 2027) and Navy Seaport-NxG/e (prime contract N0017819D7718) — alongside direct prime awards such as the June 2022 five-year, $81.6 million NSWC Dahlgren H-Department contract. Teaming relationships include SimVentions, Sabre Systems, AVIAN, Tyto Athene, AMEWAS, Prescient Edge, AT&T, and Alion; the company is also consulted by Lockheed Martin, Raytheon, and L-3 Communications for specialized technical work. Workforce of 80+ averages more than 30 years of experience with 86% holding advanced degrees. In March 2023, GTMR became a wholly owned subsidiary of Castellum, Inc. (NYSE-American: CTM) while retaining its brand, leadership team, and operational autonomy. The company has been recognized as one of Inc. Magazine's Best Workplaces in 2017 and 2019 and received the U.S. Department of Labor HIRE Vets Gold Medallion Award in 2022.
