Former Sierra Space CEO Tom Vice to lead Astrion 

Tom Vice, the former chief executive of Sierra Space, has been named CEO of Astrion, a Huntsville, Alabama-based defense contractor looking to expand its space business.

The company said April 2 that Vice will serve as executive chair and chief executive.

Astrion also named Eric Brown, previously a vice president at Lockheed Martin Space, as president of space operations and allied missions. Conn Doherty, a former executive at RTX and Chaos Industries, was appointed chief growth officer.

Vice succeeds Dave Zolet, who has led Astrion since its formation in 2023.

The appointments come as Astrion seeks to grow its space-related business lines, including systems engineering and integration work tied to U.S. military and civil space programs. The hires reflect a push to expand both domestically and in international markets.

Astrion was created through the merger of engineering firms ERC and Oasis Systems in 2023 and later absorbed Axient, a space-focused contractor, in 2024. The combined company, with about $1 billion in sales, provides technical services across defense, intelligence and civil agencies, including spacecraft development support, modeling and mission assurance.
