LΛUNCHER(@launcher):Rocket engine hardware is continuously produced from powder in our factory. We leverage 3D-printing to manufacture our single-part, LOX-cooled E-2 combustion chamber, reducing cost and part count while enabling rapid design iteration. The upgraded chamber design shown supports a lighter, simpler engine with thrust vector control. E-2 rocket engines are made in America 🇺🇸 Propellants: LOX/Kerosene Thrust: 22k lbf (10 tf) Isp Sea Level: 290 s Isp Vacuum: 327 s Isp Vac Version: 365 s Cycle: Ox-Rich Staged Combustion
