Russian internal combustion engine for medium UAVs

Bottom line

Moscow has started pilot production of a Russian internal combustion engine for medium-class UAVs, designed for 120-hour endurance.

Why it matters

Increased domestic production of long-endurance UAV engines could sustain Russian long-range strike capabilities despite sanctions.

Russian sources report that pilot production has begun for a domestic internal combustion engine for medium-class UAVs, developed by FC BAS. The engine is designed to provide 120 hours of endurance, enabling flight times of over 20 hours for infrastructure monitoring and search/rescue missions. This development aims to reduce reliance on imported powerplants for long-endurance UAVs.
