Why a future war would exhaust shells and missiles

Will future wars produce a missile shortage analogous to past shell shortages?

The forecast is shortages of both missiles and shells, because available stocks and production lines are judged insufficient for sustained war.

The forecast made in November 2025 is that sustained war would strain stocks of conventional shells as well as missiles. Limited reserves create the initial problem, and insufficient production lines restrict replenishment. Planning around a chosen, bounded operation allows expenditure to be estimated in advance. A war whose demands exceed those assumptions would expose shortages in both categories.
