The sky's balance sheet: what air defence costs, intercept by intercept
The argument that air defence is unaffordable rests on a simple comparison: a four million dollar Patriot interceptor against a thirty five thousand dollar drone. The comparison is real and it is also the least interesting number in the debate. Reported engagements show defenders firing three to four interceptors at each incoming target, which means the price list is not the bill. The number that decides a campaign is how much of a magazine one raid consumes, and 2026 produced a striking answer.
