Vast announced it will build high-power satellites alongside its space station projects, entering a rapidly evolving market. The company already operates facilities with 1 billion invested in spacecraft manufacturing infrastructure, including clean rooms adaptable for both applications. Vast's expansion comes as satellite demand surges beyond traditional government contractors.

Historically, Boeing, Lockheed Martin, and Northrop Grumman dominated large satellite construction with expensive, custom designs costing hundreds of millions. However, the Space Development Agency now favors proliferated constellations—many smaller satellites over single large targets. Falcon 9's increased launch cadence and affordable rideshare missions have lowered barriers for smaller manufacturers.

New competitors like Rocket Lab and Millennium Space Systems have emerged, though most products remain immature. Vast sees opportunity in power-hungry satellite applications where established players haven't fully optimized. The satellite population exploded from roughly 4,000 to 14,000 in five years, driven largely by Starlink expansion.

Industry estimates project 500,000 satellites in orbit within a decade. While major players like SpaceX and Amazon capture most demand, the remaining market still represents 50,000 satellites for commercial manufacturers to pursue. Vast's existing infrastructure positions it to compete for this substantial slice of the growing pie.
