From Shahed Drones To Khorramshahr Missiles, How Iran's Cheap Arsenal Is Draining US | Exclusive

An internal intelligence assessment obtained by CNN-News18 highlights how Iran’s indigenous military technology is reshaping battlefield dynamics across the Middle East, presenting a growing challenge to the United States and its allies despite years of sanctions.

The report notes that Iran’s Shahed-136 drones and their variants, produced using simple components and propeller propulsion, cost as little as $20,000-$50,000 each but have proven highly effective in swarm attacks. These low-cost systems have forced the US and allied forces to expend expensive interceptors, such as Patriot and THAAD missiles, worth millions per shot, exposing the financial strain of countering Tehran’s asymmetric tactics.

“Cheap, mass-producible drones are draining expensive Western hardware," said a senior intelligence source. In response, the US developed the LUCAS (Low-Cost Uncrewed Combat Attack System) drone, modelled on captured and reverse-engineered Shahed-136s, highlighting the urgent adaptation required to keep pace with Iranian innovations.

Iran’s missile capabilities have also advanced significantly. Systems like the Fateh-series short- and medium-range missiles and the Khorramshahr-4, with ranges up to 2,000 km, feature upgraded warheads, improved accuracy, and underground tunnel basing. These developments enable salvo strikes capable of saturating defences and targeting distant US and Israeli assets, demonstrating a level of production and operational scale that has surprised military analysts.

The country’s Bavar-373 long-range air defence system, comparable to Russia’s S-300 and S-400, uses homegrown radars and Sayyad missiles to create layered no-fly zones over strategic areas. It has reportedly intercepted advanced threats, including claims of downing stealth aircraft, forcing Western forces to rely on standoff strikes and limiting low-altitude operations near key sites such as Tehran.

Intelligence imagery from the Islamic Revolutionary Guard Corps (IRGC) shows vast underground tunnels housing hundreds of ready-to-launch Shahed drones and missiles. Combined with a Decentralised Mosaic Defence (DMD) strategy, which distributes command to survive decapitation strikes, these innovations complicate any potential invasion and prolong resistance against superior conventional forces.

Iran’s naval capabilities are also advancing. The Shahid Mahdavi multi-purpose warship, equipped with long-range cruise missiles, drones, strike systems, and new Qadr-380 supersonic anti-ship missiles, extends Tehran’s reach into the Persian Gulf and beyond.

Intelligence sources stress that Iran’s ability to combine mass drone and missile barrages, proxy force operations, cyber and electronic disruption, and foreign technology adaptations, while keeping core systems domestically produced, has strained Western military resources over prolonged engagements. Analysts warn that Tehran’s asymmetric approach may continue to erode the technological and logistical advantages traditionally held by the West.
