UEC-Klimov TV7-117ST-02 is a development-stage civil turboprop for the TVRS-44 Ladoga regional aircraft. UEC's current product page lists 2,400 hp takeoff power (1,790 kW stored), 595 kg dry mass, 0.215 kg/hp·h takeoff specific fuel consumption, 600/6,000 h initial/full interval to overhaul, electrical starter-generator start, up to 80 kVA electrical extraction, closed oil system, and 16 h continuous flight. UEC's program release describes four experimental engines for Ladoga and a planned serial-production target, while Rostec's 2026 after-sales system includes the ST-02 for Ladoga; current evidence does not establish certification or serial delivery, so lifecycle remains development.
