K2 Space, founded in 2022, is a satellite manufacturer focused on producing large, high-capacity "Mega Class" satellite buses designed for multi-orbit functionality, including LEO and MEO. They aim to offer these high-powered satellites at a lower cost compared to existing options, targeting both government and commercial applications. K2 Space has a contract with the U.S. Space Force for a 2026 mission named "Gravitas" to demonstrate its satellite's capabilities and is developing key components in-house, such as electric propulsion systems, flight computers and solar arrays. Key partners include the U.S. Space Force, Lightspeed Venture Partners and Altimeter Capital.
