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

Iran was the first country to develop Shahed drones.

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

Patriot missile systems, costing a million dollars per missile, are experiencing "leakage" as cheap Iranian drones (costing $20,000-$50,000) are getting through.

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

If defense systems have to shoot three, four, or five Patriot interceptors to knock down one drone, the cost becomes 15, 20, or $30 million per $20,000 drone.
