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

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.

Iran bypassed the Iron Dome using wooden stealth drones.

Iran has fired off more than 2,000 one-way drones since the United States and Mistral started attacking it on Saturday.

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