The Economics of Shooting Down Drones
Why the Iran conflict may be decided by cost per interception
🎯 Three-Shot Burst
Special guest POV by🍁 Cameron Rowe, Co-Founder at Sentradel
Modern air defence was built for Cold War threats like fast jets, cruise missiles, and ballistic missiles. Systems like Patriot, NASAMS, and Iron Dome use radar to detect objects, calculate trajectories, and fire interceptors moving several times the speed of sound. A Patriot interceptor can travel above Mach 4 and costs roughly $5-$6 million.
Reality check: These systems work well against traditional threats, but drones introduce new problems. A one-way attack drone like Shahed-136 flies about 150-190 km/h, carries a 30-40 kg warhead, and costs ~$20,000. They can be launched in large numbers and fly very low.
Detection is harder than it seems in practice. Most drones have very small radar cross sections. A Shahed is around 0.01 to 0.03 square meters, which is tiny for legacy radars. Their slow speed also creates problems because radar software often filters slow objects to remove birds and ground clutter. A drone can look a lot like noise.
Low altitude flight makes things worse because of the radar horizon. A drone flying at 50 to 100 meters may not appear at all until it’s too late.
Bottom Line: Interception is expensive. Missile defence has never been fully solved, even for nuclear warheads, because saturation overwhelms defences.
Drones recreate the same saturation problem at far lower cost. It’s a cost curve problem disguised as a missile problem. And cost curves, historically, are where technology revolutions hide.
Ukraine shows us both progress and limits. Shaheds are intercepted with missiles, anti-aircraft guns, machine guns, MANPADS, and electronic warfare such as jamming. Systems like the Gepard and ZU-23-2 are used alongside older heavy machine guns like the DShK.
The central issue remains simple: focus on cost per interception — a layered approach with solutions that work and scale.

🤝 Deal Corner
Dominion Dynamics to build a sovereign autonomous wingman
Dominion Dynamics says it will invest $50 million to build Canada’s very own “autonomous wingman” to fly alongside crewed air fighters.
CEO Eliot Pence said in a statement that the systems “will allow Canada to operate effectively in the most contested and remote environments, including our own Arctic.”
On top of potentially preserving the lives of crewed aircraft, Autonomous Collaborative Platforms can also expand the reach and sensing capability of allied forces with persistent surveillance, electronic warfare, and strike support, the company added.

How Iran’s missile arsenal is being wiped out
Iran’s missile threat has been severely degraded, with some estimates claiming as much as 70% of its launchers destroyed.
How does it work?: Satellites spot a missile launcher and instantly beam coordinates to the nearest F-35 which fires without ever seeing the target.
As Iran tries to move a launcher, U.S. satellites see it glowing like a matchstick from space, and can target the source. Every time a launcher launches a missile it exposes its position. They’re designed to be reusable but under these conditions they’re mostly only getting off one shot.
