Shahed drones are unmanned aircraft that can carry powerful explosives as far as 2,000 km.

Iran was the first country to develop Shahed drones.

Iran's Shahed drones are a bigger problem than the US was anticipating, according to Trump administration officials who told lawmakers during a closed-door meeting.

Iran is producing drones for about $30,000 a piece.

Shahed drones have also been used by Russia in its war against Ukraine.

Each Shahed drone costs between 20 and 50 grand to manufacture, built with off-the-shelf commercial electronics.
