Since remnants of a jet-powered Shahed were found near Kyiv in June 2025, Russia’s upgraded Geran family of kamikaze UAVs has outpaced Ukraine’s existing air defenses. Manufactured at Yelabuga, the Geran-3, -4 and -5 evolved quickly: Geran-3 (Telefly JT80) tops about 370 km/h but is poorly maneuverable; Geran-4 pairs a stiffer, reworked airframe with more powerful Telefly LX-WP-160/TF-TJ2000A engines to reach roughly 500 km/h and execute evasive moves; Geran-5 is cruise-missile shaped, reaches 6-7 km altitude and extends range to about 1,000 km. Russia scaled production and deployment sharply - reported launches climbed from ~350 per month in June to ~2,800 in August - despite unit costs near $80,000, and the fast, high-flying Gerans are striking cities far from the front lines.
Existing Ukrainian interceptors, largely propeller-driven, are too slow and have short engagement windows; practical interceptor speeds top out around 300-450 km/h, and even slight maneuvers by the incoming Gerans cause misses. Defenders now face a technical pivot: develop jet-powered interceptors and domestic small jet engines, and shift toward high-speed autonomous guidance because human reaction times and current compute-heavy AI boards are impractical at scale. Potential solutions include leaner neural nets or switching from image guidance to thermal, RF or acoustic homing to cut computing cost; failure to adapt risks a sustained attacker-favorable cost-exchange ratio.
