    For what? Their own kick stage or tug, like what Impulse is doing? This seems like a bigger RL-10, so it’s kind of a lot of engine, and I don’t really understand what it’s for.

      Sierra Space is positioning the VR35K-A for the launch market but also for in-space propulsion use, including spacecraft orbital maneuvering and lander descent systems. The company’s Dream Chaser spaceplane, designed to deliver cargo to the International Space Station and other destinations in low Earth orbit, uses Vortex-based reaction control system thrusters.

      I guess it’s for anyone who wants a 35,000 lbf vacuum engine?
