Iran presented the latest version of its kamikaze drone at a military parade in Tehran on September 21. State broadcaster IRIB reported that the Shahed 136-B drone has a range of 4,000 kilometers. Iran claims to have made great strides in the production of drones in recent years. They are said to play a central role in Russia's invasion of Ukraine, though Tehran categorically rejects accusations it is supplying Moscow with weapons for its unprovoked aggression.
