LΛUNCHER(@launcher):A six-minute E-2 test fire has been completed successfully as the team develops systems for E-2 Vacuum. This test demonstrated the propulsion system's ability to sustain a representative burn duration needed to raise spacecraft to higher energy orbits. The engine operated at nominal conditions, including the first 200 seconds at 102 bar chamber pressure while gimbaling. Propellants: LOX/Kerosene Thrust: 23k lbf (10.4 tf) Isp Sea Level: 290 s Isp Vacuum (SL nozzle): 327 s Isp E-2 Vacuum: 365 s Cycle: Ox-Rich Staged Combustion
