underwent a spot check hot fire test for the first flight batch, fully simulating the flight conditions of the inaugural Tianlong-3 launch. The test involved 6 consecutive ignitions of the engine without removal from the test stand, accumulating a total test duration exceeding 1,000 seconds, with the single engine operating time surpassing the planned flight duration by a factor of 6.
