If F-47 direct drone swarms to annihilate Iran’s missile and launcher production, then the numbers look much better.
However, your analysis is deeply flawed. The calculation using the cost of the Iranian missiles is almost irrelevant. The number to look at is the cost of the destruction and lives lost, and downstream effects the missiles can cause.
Another calculation is the cost of defensive missiles. Patriot batteries typically fire 2 or 3, and sometimes as many as 4 Patriot missiles at an incoming missile - this sometimes depending on the value of the incoming missile’s evident target. If a F-47 + drone swarm and / other munitions it directs from a relatively safe vantage can shellack some enemy missiles B4 deployment or launch, or, again, missile or launcher production, those enemy missiles will never require expensive Patriot launches.
Further, establishing air dominance reduces all sorts of other costs and losses.
Now, it is true, right at the moment, we DO urgently need Ukie quantity* cheap drones and command / control capability. But going forward, we will need ever more effective and advanced systems and platforms, and redundant / parallel systems and platforms at that, to manage / command them.
*The Ukies, with limited resources compared to the US, and under fire, are on track to produce 10 MILLION drones in 2026.
“F-47’s” I should have typed. I got a little too hasty with my edit!
