On May 27, Rocket Lab announced that it would be acquiring Geost, a producer of electro-optical and infrared sensors, for $275 million. This puts Rocket Lab in a unique position where it is vertically integrated to build, launch, and operate missile tracking satellites pretty much on its own.

Combined with the ongoing acquisition of Mynaric, announced on March 11, who manufacture optical-intersatellite links, the company is now poised to provide a solution as part of the Space Force’s Proliferated Warfighter Space Architecture (PWSA) which seeks to track hypersonic gliders and ballistic missiles. Rocket Lab was already selected to provide 18 satellites as part of the Tranche 2 Transport Layer which forms the communication backbone of the PWSA as well as the future Golden Dome .
