Motor Sich D-18T Series 3 is the exact grouped D-18T Series 3A/3M high-bypass turbofan variant in the canonical Ivchenko-Progress D-18T family, for An-124 and An-225 heavy transports, with a fan-duct thrust reverser. The current manufacturer page publishes 23,430 kgf (229.85 kN) SLS/ISA takeoff thrust, 4,860 kgf (47.69 kN) maximum-cruise thrust at 11,000 m/M0.75, and 4,150 kg dry mass. The exact series node remains distinct from the broader D-18T identity; lifecycle remains unknown.
