About the company
Interoperable Systems Group LLC is a for-profit limited liability company headquartered in Fort Worth, Texas, that specializes in tactical data link solutions and software for defense agencies. The company has maintained continuous registration in SAM.gov since November 2006 and has established itself as a key provider of mission-critical command and control systems software to the Department of Defense. Interoperable Systems Group LLC develops and maintains specialized software suites designed to support message analysis, testing, and interoperability evaluation of military communication systems, with particular expertise in Link 16 platforms and tactical data link infrastructure.
The company has secured substantial federal contract awards totaling over $4 million from multiple defense agencies, including the Naval Air Warfare Center, Naval Information Warfare Systems Command, Air Combat Command, Air Force Test Center, U.S. Marine Corps, and Naval Air Systems Command. The primary focus of these awards centers on the MANDRIL software suite—an integrated tactical data link analysis and testing system—along with related products such as CIVET software, ESMART (Electronic Systems Management and Requirements Tool Set), and iSMART training services. Contract awards have been structured as firm-fixed-price purchase orders and definitive contracts ranging from approximately $20,000 to nearly $2 million, with the largest award being a $1,965,990 definitive contract from Air Combat Command for 120 ESMART licenses and associated training through January 2029. The majority of these awards have been sole-source procurements without small business set-asides, reflecting Interoperable Systems Group's status as the original equipment manufacturer and exclusive supplier of MANDRIL and related software suites. The company has also been engaged as a subcontractor through prime contractors including Lockheed Martin Corporation, J.F. Taylor, Inc., and The Mitre Corporation, providing MANDRIL subscription renewals, software licenses, and training services. Performance locations have primarily been in Benbrook, Texas, with some work conducted at other defense facilities including Patuxent River, Maryland, and China Lake, California, supporting ongoing maintenance, licensing renewals, and software enhancement initiatives across military air and naval platforms.
