7-ton-class liquid engine
KARI 7-ton-class liquid rocket engine is the kerosene/liquid-oxygen third-stage engine of Nuri (KSLV-II). KARI specifies one engine on the third stage and a 187 kg engine mass; the KARI engine page records development through power-pack tests, the first combustion test in July 2015, and 11 engines subjected to 89 tests with 16,385.7 s of cumulative burn time. This generic record preserves the class identity and does not assert a distinct named model.
