Altamira Technologies on Wednesday said it has acquired Virginia Systems & Technology (VaST), which provides signals intelligence (SIGINT) expertise to national security customers.

Terms of the deal were not disclosed.

VaST, which is based in Warrenton, Va., and has employees in nearly a dozen U.S. locations as well as Australia and the United Kingdom, has expertise in end-to-end SIGINT tasking, collection, processing, exploitation, and dissemination, national/technical SIGINT collaborative constellation management, and emerging threat identification.

Altamira, which is based in McLean, Va., said the acquisition will add talent in the areas of software development, data science, operations, mission integration, and analysis.

“The acquisition of VaST brings new SIGINT capabilities and core national security customers to the Altamira portfolio,” Jane Chappell, CEO of Altamira, said in a statement. “VaST’s culture of marrying elite engineering with critical operations is a strong match with Altamira.”

Altamira is a portfolio company of the venture capital firm ClearSky. Altamira has a broad range of capabilities in signals analysis, cyber operations, intelligence analysis and reporting, artificial intelligence and advanced analytics, sensor integration and development, software engineering, and multi-intelligence analytic solutions.
