Vencore, Inc.

Vencore, Inc. is a private defense contractor that serves the U.S. Intelligence Community, Department of Defense and other agencies. From 2010 to 2014, the company was named The SI Organization, Inc. (the SI). The SI provides full life cycle, mission-focused systems engineering and integration capabilities, according to its corporate website. Major locations include Chantilly (VA), Basking Ridge (NJ), Denver (CO), Laurel (MD), Los Angeles (CA), Red Bank (NJ), St. Louis (MO), and Valley Forge (PA). The company employs approximately 2,000 people.

The SI was founded in 1972 in Valley Forge, Pennsylvania, as part of GE Aerospace, when a team of 60 engineers began providing systems engineering and integration services to the Intelligence Community. The System Integrator construct was conceived by the US Government to help implement a very large, complex, and expensive space-based national security program. Due to the success of the construct, the SI grew throughout the 1980s and 1990s, as part of Martin Marietta and later Lockheed Martin, expanding into Northern Virginia and Maryland. The SI was divested by Lockheed Martin in 2010 and acquired by private equity firm Veritas Capital.

In 2012, the SI acquired PhaseOne Communications, a company that provides strategic communications services. In 2013, the SI acquired Applied Communication Sciences. ACS has capabilities in cybersecurity and information assurance, network and operations, data analytics, advanced software and methodologies, wireless and mobility, application engineering and integration, smart grid, and optical networking and quantum technologies.
