How fast does the stockpile come back? This projects it forward from the deliveries already in the pipeline and the FY2027 rebuild order, using the budget's own schedules. Move the sliders to test faster production or a renewed war.

Published estimates Projection Low–high range Prewar level

Starts from the newest estimate (Apr 8, 2026) and assumes no firing after it unless you add a renewed war. Fighting has continued at lower intensity since July 8, so treat projections from older estimates as optimistic. The default firing rate is the opening campaign's average: ~28 a day over 39 days.
