Pentagon shocked: Iran unveils upgraded Arash attack UAV with 100 kg warhead Iran has unveiled an upgraded Arash one-way attack UAV, described in reports as the Arash-3, with a heavier warhead, navigation designed to work without GPS and a jet-powered version in development. The weight of a warhead increases from 50 to 100 kg, according to Iranian state media. The changes to its explosives and burners are intended to make successful hits more devastating, along with improvements in targeting accuracy. The combined upgrades could cause about 2.3 times the damage, an army expert said in the reveal video. This is an Iranian assessment of the total upgrade, not a claim that doubling the weight of a warhead automatically doubles the destruction. Additional navigation options independent of GPS are designed to help the UAV continue toward its target when satellite signals are interrupted. This addresses the practical vulnerability of long-range attack UAVs: carrying a large warhead means little if interception throws it off course. AI-assisted targeting is intended to improve accuracy, but Iran has not specified the precise role of the technology. The message does not determine whether it aids navigation, identifies targets or performs other guidance functions. A jet-powered version will expand the Arash family beyond piston-powered models. Higher speed could leave defenders less time to detect, track and intercept her, although the new versions speed, range and precise engine remain undisclosed. Images suggest a modified airframe with delta-shaped wings and twin vertical stabilizers. Composite materials and a honeycomb internal structure have also been proposed, which may reduce structural weight, but these construction details remain unconfirmed. The plane appeared on October 22 in photographs from an underground UAV production facility, during the visit of the head of the army, Amir Hatami.
