An aerial drone capable of materially damaging a modern navy ship costs $1-2M a piece. Anything much cheaper doesn't have the range, survivability, or required warhead to do much more than scratch the paint.

A cheap drone is only useful against soft targets. It is the reason Ukraine is scaling up heavy cruise missile production even though they already have vast numbers of cheap long-range drones. Being "cheap" isn't of much value if it is incapable of doing meaningful damage to the desired target.

The US has been designing and building thousands of anti-ship drones since the 1970s. It isn't like they have no experience with the concept and those drones are far more capable than anything Iran has. The US Navy has assumed drone swarms as a threat model for half a century.

Do the Iranians have to win against a Navy ship or an oil tanker? Asymmetric warfare suggests they would ignore the well fortified ship and wreak havoc on commercial shipping to get the same result. The Strait of Hormuz is so shallow and narrow that they only really need to sink two or three tankers to shut the whole thing down.

These boat drones ukraine used to sink some russian ships seem to be very hard to avoid.

Problem isn't a single drone, it's the cost of intercepters. Iran could launch a swarm of 100s of drones with few antiship missiles mixed in to hone in at same time. CSG has to spend $million+ interceptors and will quickly run out of them. US hasn't taken anti drone defence seriously, or the cost of doing it seriously before going in.

Unless Iran bought some CM-302 missiles from China, the mere threat of which appears to mean that China and Iran now control the oil in the gulf.

But ELI5 me maybe I don't understand realpolitik
