Terms of the deal were not disclosed. Fourth Dimension is located in Columbia, Md., near the National Security Agency and U.S. Cyber Command. The company has 79 employees.

“This acquisition firmly establishes Polaris Alpha as a preeminent leader in all aspects of advanced cyber operations,” Peter Cannito, CEO of Polaris Alpha, said in a statement on April 16. Geoff Bloom, executive vice president for Cyber and SIGINT at Polaris Alpha, said in a statement that “Combining their unique hardware expertise with Polaris Alpha’s complementary cyber and signals intelligence capabilities significantly increases the scale of our advanced cyber offering.”

Fourth Dimension says its quick reaction capabilities in electronic solutions means schedules of “hours to weeks.”

Fourth Dimension’s strengths in hardware design, mechanical engineering and RF design are areas that Polaris Alpha wanted to expand. Fourth Dimension also brings additional customer relationships within the Defense Department.

SC&H Group served as Fourth Dimension’s financial advisor on the deal, which closed on April 11. Fourth Dimension co-founders and senior executives Tom Conrad and Faith Horowitz have joined Polaris Alpha’s management.

Polaris Alpha, which has 1,300 employees, is focused on mission support.
