About STS International, Incorporated
STS International, Incorporated is a veteran-owned business headquartered in Arlington, Virginia, specializing in providing comprehensive engineering, logistics, technical services, and program management support to the U.S. federal government. The company focuses primarily on defense and national security sectors, with a particular emphasis on Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) systems. As a strategic federal contractor, STS International has established itself as a key provider of advanced technological solutions and support services for military and government agencies.
Through its federal contract awards, STS International has demonstrated extensive capabilities in delivering a diverse range of goods and services. The company's contract awards predominantly involve supplying technical components such as circuit card assemblies, power supplies, antennas, electronic amplifiers, dynamic seals, and specialized equipment like servoactuators and magnetometers. Most of these contracts have been awarded by defense agencies including the Naval Supply Systems Command, U.S. Army Communications Electronics Command, and the Program Executive Office for Combat Support and Combat Service Support (PEO CSCSS). The majority of these awards are not set aside for specific business types, indicating STS International's competitive positioning. Additionally, the company has provided technical support services like Combat Field Service Equipment Team personnel, CONUS Lead and Senior Technician services, and logistics support for fielded equipment around the globe.
STS International holds three significant Indefinite Delivery Vehicle (IDV) contracts that showcase its strategic importance in federal contracting. The $3.2 billion C5ISR Gateway to Sustainment (G2S) multiple-award contract covers sustainment solutions for over 263 Army C5ISR systems, enabling the company to provide a wide range of goods and services through task orders. The $906.57 million Joint Enterprise Contracted Logistics and Services Support Class II (JE-CLASS II) contract focuses on logistics and services support for chemical, biological, radiological, and nuclear defense systems. The company also recently secured a position on the OASIS+ Small Business Multiple Award Contract with a potential $999.99 trillion ceiling, which allows it to provide professional services across seven functional domains including management, technical engineering, research and development, intelligence, environmental, facilities, and logistics services. These IDVs demonstrate STS International's robust capabilities and strategic positioning in supporting complex federal government missions.
