While the Houthi drone itself is inexpensive, the cost to the economy of a drone hitting shipping is substantially greater than the $3M cost of the US interceptor missile.
Good.How about ten drones ($200k) and ten interceptors ($30m)? Is the cost of the economy still greater? Alright, let's up the numbers. Forty drones vs forty interceptors, $800k vs $120m. Do the numbers still work for the US? Like, would Yemen gladly pay $800k to kill an american vessel? I guess yes. Would it be economically effective to spend $120m on a protection of said vessel? Perhaps not.
So, at a certain number between one and forty drones the economy stops making sense.
This is what happens here in Ukraine as well: russian drones are cheap and readily available, while interceptors are expensive af and quite scarce.
the average value of goods per container ship is ~$350M per ship not including the value of the ship itself. However I think the impact to the economy from a missile hitting a ship far exceeds the value of the goods, the ship, and the cost of any missiles used to defend those goods.
