Israel struck 50 ammunition storage shelters across Iran on Day 10 — the largest single-day operation against dispersed stockpile infrastructure since the war began. The strikes complement the same day's hits on IRGC Aerospace Force and drone headquarters: command nodes and supply chain targeted in a single wave.
The ammunition attrition campaign has been building across ten days. B-2 bombers struck deeply buried ballistic missile launchers during the first week. More than 80 aircraft dropped 230 bombs on Imam Hossein University — the IRGC's primary military academy — on Day 8. CENTCOM's cumulative tally exceeds 3,000 targets struck. The 50-shelter operation extends this attrition to the dispersed storage sites feeding Iran's provincial launch networks under its Mosaic Defence Doctrine — the very infrastructure that enabled 109 drones and 9 ballistic missiles at the UAE on a single day.
The timing alongside Iran's doctrinal shift is difficult to disentangle from the stockpile question. Commander Mousavi's announcement that Iran would fire only warheads above one tonne reads differently when set against the sustained destruction of ammunition depots. The shift from saturation to concentration — fewer launches, heavier payloads — may reflect deliberate strategic choice. It also aligns with what ten days of strikes on production and storage infrastructure would produce: depletion of the lighter munitions that enabled early-war barrages. Whether Iran holds sufficient one-tonne warhead inventory to sustain the new doctrine at operational tempo is the question the announcement does not — and cannot — answer. The shelters struck on Day 10 are part of the answer Iran would prefer to keep hidden.
