Washington Harbour expands space investments with ground services acquisition

WASHINGTON — Washington Harbour Partners has acquired Radome Services, a New Hampshire–based provider of inspection, repair and maintenance services for ground facilities that protect satellite, radar and communications antennas at military and government sites.

The newly acquired company is being rebranded as Outpost Mission Services and positioned as a provider of engineering services supporting the critical infrastructure that underpins space operations, said Mina Faltas, founder and chief investment officer at Washington Harbour, based in Arlington, Virginia. The amount of the investment was not disclosed.

The ground segment of the space industry, Faltas said, is an area that is drawing increased attention as satellite systems proliferate and demand grows for resilient infrastructure on the ground.

Founded in 2010, Radome Services has operated as a privately held field-services company with about 45 employees. It specializes in installation, inspection, repair and maintenance of radomes — protective enclosures used to shield antennas from weather, environmental degradation and interference — as well as related antenna work. The company serves government and commercial customers.

Faltas said the acquisition and rebranding, announced Jan. 20, are intended to establish Outpost Mission Services as the foundation of a larger platform. “This is a private equity investment, where we bought a company and we’re creating a platform, meaning we will buy other companies and merge them with this company,” he told SpaceNews.

“Washington Harbour is deploying significant resources alongside Outpost to build a market leader,” Faltas said. “The next generation of space superiority depends on resilient ground infrastructure.”

The deal reflects a broader shift in private capital toward national security and space-related assets that offer stable, non-cyclical demand. By acquiring Radome Services and turning it into a platform company, Washington Harbour is positioning itself to capitalize on that trend.

Washington Harbour’s space investments to date have largely centered on software-heavy companies tied to space operations, autonomy and decision-making, including Trusted Space, Turion Space, Quindar and Array Labs. The firm also joined the Series D round for Stoke Space, a space launch startup. Outpost represents a different layer of the space architecture: the physical ground infrastructure that enables satellite command and control, communications and sensing.

Radomes are used at military satellite communications sites, missile warning facilities, space surveillance radars and intelligence ground stations. As U.S. officials warn about potential threats to those facilities — ranging from cyber intrusion to physical attack and environmental stress — maintaining and hardening ground systems has become a more pressing concern for the Pentagon.
