170-ton-class liquid engine
KARI's Naro (KSLV-I) used one Russian-developed 170-ton-class kerosene/LOX liquid engine in its first stage. KARI describes turbopump feed and a 170-ton first-stage thrust class; this record remains a generic propulsion identity rather than a named Russian engine model. Naro flew on 25 August 2009, 10 June 2010 and 30 January 2013, and the program ended after its successful third launch.

- Note
- KARI's NARO page identifies a 170-ton liquid engine for the first stage, using kerosene and liquid oxygen supplied through a turbopump, and records the three launch dates and the successful third launch. The stated 170-ton thrust class is normalized to 1,667.1 kN using standard gravity; no named Russian engine model is asserted.
