LΛUNCHER(@launcher):E-2 delivers unmatched performance in the small launch class. Operating at an optimal mixture ratio with 99%+ combustion efficiency, it produces a distinctive blue, transparent plume, which is unprecedented for kerosene engines. Designed for rapid reusability, E-2 maximizes specific impulse, increasing payload capacity and overall value to orbit. For a given rocket, higher engine performance enables more payload to be flown in place of propellant compared with lower performance engines. 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
