Four firings of the Rocketdyne J-2 rocket engine were conducted on August 22, 1967 in Propulsion Engine Test Cell (J-4) of the Large Rocket Facility, Arnold Engineering Development Center. The firings were accomplished during test period J4-1801-06 at pressure altitudes from 103,000 to 108,000 ft at engine start. The objectives of the test included the evaluation of (1) thrust chamber ignition characteristics with low augmented spark igniter mixture ratio and (2) the effects upon engine starting transients of minimum fuel pump inlet pressure and thrust chamber resistance for first orbit restarts with maximum starting energy.
