QuantiTech LLC, a provider of engineering services to Defense Department customers and NASA, on Monday said it has acquired Dynamic Concepts, Inc. (DCI), a small company that provides engineering services to NASA mainly related to human space flight.

Terms of the deal were not disclosed. DCI’s management team will remain with the company.

DCI, which is based in Huntsville, Ala., and has more than 70 employees, supports NASA’s Space Launch System and docking system and test and analysis for the International Space Station. The company also supports the Defense Department with small satellite design and commercial customers.

DCI specializes in classical and structural dynamics, digital and hardware-in-the-loop simulation, custom software applications, and control systems design and analysis in support of human space flight.

QuantiTech, which is also based in Huntsville, is a portfolio company of the private equity firm Sagewind Capital, which invested in the company earlier this year. DCI is the first deal for QuantiTech since the acquisition by Sagewind.

“QuantiTech partnered with Sagewind Capital in May because we were searching for a partner that would support our growth as we strive to better support our customers’ critical missions,” Darryl Wortman, QuantiTech’s president and CEO, said in a statement. “DCI is an excellent addition to QuantiTech as it provides us with a complementary set of high-end specialized services and bolsters our existing relationship with NASA.”

QuantiTech’s capabilities are focused on systems engineering, cyber security, test and evaluation, and program management in areas such as hypersonic, counter-drone systems, and human spaceflight.
