Sunfire is Sunride’s liquid rocket program. We were the first UK team to hot fire a 3D printed, regeneratively cooled rocket engine at the first ever Race To Space competition.

In 2024, we developed the next iteration of this engine which we plan on integrating into a rocket, with the goal of launching the UK’s first student-built liquid rocket.
