The discussion treats missile scarcity as an industrial-capacity problem rather than merely an inventory count. Factories had not yet been worked up to replenish stocks at the rate wartime expenditure required. Rising scrap-metal prices are offered as a rough market sign that ammunition producers were buying more feedstock. That price movement is a broad indicator rather than a count of any particular weapon. Weapons availability depends on the depth of the munitions industrial base.

Missile stocks, factory throughput, and scrap-metal demand
A supply-chain aside connects scarce missiles to factories that had not expanded replacement output and treats rising scrap-metal prices as a rough signal of ammunition demand.
