Economist Podcasts – "Blood from a drone: Iran’s deadly arsenal"

Episode Date: March 12, 2026
Hosts: Jason Palmer, Rosie Blore
Guest: Shashank Joshi (Economist Defense Editor)

Episode Overview

This episode focuses on the mounting threat posed by Iran’s deployment of cheap, precise, and deadly drones during the ongoing conflict with Israel and the West. Defense Editor Shashank Joshi analyzes the mechanics, strategy, and global proliferation of Iranian drones—particularly the Shahed type—and what the conflict reveals about evolving modern warfare. The episode explores drone effectiveness, defense tactics, and lessons from the Ukraine war, concluding with insights on geopolitical leverage and the global arms market.

Key Discussion Points & Insights

The Current State of the Conflict

• Iran’s Drone Assault: Nearly two weeks into the war, Iran has escalated its response, attacking foreign tankers, striking regional energy infrastructure, and threatening Western financial institutions after a Tehran bank was hit.
• Wider Use of Drones: In addition to ballistic missiles, Iran’s extensive arsenal of drones—cost-effective and tactically flexible—is shaping the conflict.

Iran’s Shahed Drones: Capabilities & Proliferation

[02:39] Shashank Joshi:

• Iran has launched over 2,000 Shahed-type drones at Israel, Arab countries, and as far as Cyprus during the conflict.
• Drones have struck American facilities, including embassies and military bases, killing troops and destroying valuable radar assets.
• While many are intercepted over long distances, at close range they remain highly effective and dangerous.

Quote: “They’ve killed American troops. They’ve even destroyed some of America’s most valuable military radars in the region... At short range they have proved very effective, very dangerous, and a really formidable threat in this conflict.”
— Shashank Joshi [02:56]

What Makes Shahed Drones So Effective?

[03:28] Shashank Joshi:

• Shaheds are delta-wing drones, originally manufactured and used by Iran but popularized through Russia’s use in Ukraine (rebranded as Garans).
• Russia has produced and improved upon them domestically, launching them in large numbers against Ukraine.
• They blur lines between drones, cruise missiles, and manned aircraft—enabling new forms of attack.

Quote: "For me, they epitomize the way in which the boundaries... between a drone, a kamikaze drone, a missile, a cruise missile, an aircraft... has just blurred."
— Shashank Joshi [03:55]

• Iran manufactures these domestically, though Russian operational support has contributed to their effectiveness.

Why These Drones Dominate the Battlefield

[04:22] Shashank Joshi:

• Shaheds travel slower and carry smaller warheads than ballistic missiles, but they’re vastly cheaper—about $55,000 each, possibly $100,000 with enhancements—allowing for mass production and deployment.
• Launch flexibility: Shaheds can be launched from trucks or dispersed sites, unlike bulkier missiles needing detectable silos.
• Flight advantages: They fly low and can skirt traditional radar by skimming the ocean—making them hard to detect and intercept.

Defense Against Drone Swarms—Challenges and Innovation

[05:23] Shashank Joshi:

• High-tech interceptors like Patriot or Thaad systems are capable but not cost-effective for taking down cheap drones.
• Alternatives include:
  • Air-to-air missiles from fighter planes
  • Laser-guided rocket pods (cheaper at close range)
  • Anti-aircraft cannons repurposed for drone defense
  • Nascent laser systems (e.g., Israel’s Iron Beam), though weather conditions like dust can limit effectiveness.
• Central challenge: Balancing defense costs with affordable, sustainable solutions.

Quote: “The problem is you are taking out a $55,000 Shahed with an interceptor that costs much, much more... What you want to do is try and use cheaper means.”
— Shashank Joshi [05:31]

Tactical Lessons from Ukraine

[07:11] Shashank Joshi:

• Ukraine has pioneered cost-effective methods to counter Shahed drones, notably using "drone-on-drone" tactics with FPV (First Person View) racing drones as interceptors.

• These interceptors are small, maneuverable, and (in recent versions) AI-guided for autonomous engagement.

• Ukraine also innovates by deploying interceptors from uncrewed boats to counter drones skimming over water.

• Data from January: Of 1,700 Shaheds launched, half were destroyed—about 70% by FPV interceptor drones.

Quote: “What they’ve basically hit on is a really interesting method that uses a drone to kill a drone... And some of the most recent drones Ukraine is using for this purpose have AI guidance.”
— Shashank Joshi [08:07]

• High skill is needed; a few well-practiced units made most successful intercepts.

Global Proliferation and Power Dynamics

[09:36] Shashank Joshi:

• Ukraine is already sharing its skills and technology with the Gulf states, eager to exchange know-how for investment or aid.
• Gulf nations' heavy consumption of expensive interceptors highlights their demand for more efficient solutions.
• Ukrainian President Volodymyr Zelenskyy sees this as a strategic opportunity—Gulf nations have capital; Ukraine has proven tech.
• There’s also an implicit message to Western allies: Ukraine’s expertise is valuable but contingent on reciprocal support.

Quote: “Gulf has money, Ukraine has tech. It’s an obvious marriage of skill and cash.”
— Shashank Joshi [10:16]

• The arms technology market is rapidly globalizing, with tactical skill becoming a new form of geopolitical capital.

Memorable Moments & Notable Quotes

• Low-Cost, High-Impact Warfare:

  "But these are fundamentally very cheap compared to a ballistic missile. And so that low cost allows Russia or any country like Iran now to churn out huge numbers of these per day."
  — Shashank Joshi [04:32]

• The Cat-and-Mouse Game:

  “There’s a constant game of cat and mouse. But the point is, the Ukrainians are so far ahead in that game that they have huge amounts of the expertise necessary for this problem today.”
  — Shashank Joshi [09:13]

• Strategic Leverage for Ukraine:

  "He is willing to, yes, give this technology to the Gulf, but I think naturally he’d be looking for Gulf investment in Ukrainian production.”
  — Shashank Joshi [09:49]

• Challenging Received Wisdom:

  “As Donald Trump famously said, Ukraine has none of the cards. I think we’re clearly seeing Ukraine does in fact have plenty of cards.”
