K2 Space, a developer of large, high-power satellite platforms, has secured $250 million in Series C funding at a $3 billion valuation to advance production of heavy-lift spacecraft.
Who Participated in the Investment Round for K2 Space?
The Torrance, California-based company said Thursday that Redpoint led the financing round, which follows $500 million in signed contracts with commercial and U.S. government customers. The investment round includes participation from accounts advised by T. Rowe Price Associates and from Hedosophia, Altimeter, Lightspeed and Alpine Space Ventures. This follows its Series B funding round in February, which raised $110 million.
What Are K2’s Launch Plans?
K2 plans to launch its first Mega Class satellite, GRAVITAS, in March 2026. It is designed to fly on Falcon 9, Vulcan or Ariane 6, operate across multiple orbits, and test a 20-kilowatt Hall-effect thruster, large solar arrays and high-voltage power systems.
“GRAVITAS brings our full stack together for the first time. We are validating the architecture in space, from high-voltage power and large solar arrays to our guidance and control algorithms, and a 20 kW Hall thruster, and we will scale based on measured performance,” said Karan Kunjur, co-founder and CEO of K2.
How Will K2 Scale GRAVITAS Production?
Following the launch, K2 will ramp up production at its 180,000-square-foot Torrance facility, with an annual capacity of 100 satellites. The company plans multiple launches through 2027 and deployments starting in 2028.
