CesiumAstro is a startup specializing in phased array communications for aerospace applications. It manufactures antennas that support in-flight connectivity and satellite communications, addressing the significant data transfer needs of AI and autonomous vehicles.
This type of communication support is vital nowadays, when the transfer of massive amounts of data is mission-critical. The company's first antenna flew in 2023 as part of a payload for defense contractor CACI International. CesiumAstro also secured a lucrative subcontract with RocketLab to provide antennas for the Space Development Agency.
CesiumAstro has secured immense funding over the years, including a record $200 million in government financing in 2026. This investment continues to support the company's growth, R&D and manufacturing goals. It comes alongside an expansion of operations which sees CesiumAstro supporting national security.
