The maximum afterburner thrust was 10.100 kgf, with a specific fuel consumption of 2,25 kg/kgf*h. The maximum thrust in the without afterburner mode is 6.900 kgf, with a fuel consumption of - 0,96 kg / kgf * h. The length of the engine is 6.630 mm, the diameter of the engine is 1.250 mm and the mass of one engine with units was 2.454 kg.
