Geran-2 Drones Evolved into Network-Centric Combat System (defence24.com)

• Kometa-M antenna arrays enable spatial nulling of up to three jammers
• 4G/LTE modems and Raspberry Pi provide backup communication when GPS is jammed
• Carbon-fiber airframe with radar-absorbent coating reduces radar cross-section

"Russia has transformed Iranian Shahed-136 drones (Geran-2) into a network-centric combat system. Key upgrades include Kometa-M antenna arrays for electronic warfare nulling, 4G/LTE modems for backup communication, SADRA inertial navigation, and carbon-fiber airframes. Starlink integration was briefly successful but blocked by February 2026. The jet-powered Shahed-238 (Geran-3) was developed with Iran. Ukraine destroyed over 33,000 enemy drones in March 2026 alone."
