Iran Launches Fourth Missile Volley in Six Hours; Air Defense Saturation Now Operational Tactic
High-frequency Iranian strikes accelerate Israeli air defense attrition, directly constraining Israel's ability to sustain the 400+ daily strike tempo announced April 1 without risking undefended airspace.
If Iran maintains four-wave cycles, Israeli interceptor consumption will force either a reduction in offensive operations or emergency resupply from US stocks — both outcomes reduce Israel's operational freedom and compress the 2-3 week exit window Trump outlined on April 1. This converts the conflict from a duration problem (how long can Israel strike?) into a logistics problem (can the US restock fast enough?).
This represents a tactical shift from Iran's earlier volleys (March 31, April 1) toward sustained, high-frequency strikes designed to stress Israeli air defense capacity rather than achieve concentrated damage.
The four-wave pattern in six hours suggests Iran is testing saturation thresholds and forcing continuous active engagement of Patriot, David's Sling, and Arrow systems. If Iran sustains this cadence, Israeli interceptor stocks become the binding constraint on defense duration — each volley consumes finite munitions.
The question for defense planners: how many more cycles can Israel's layered defense absorb before attrition forces a shift to ground or diplomatic response? Trump's April 1 ceasefire condition (Hormuz access) remains unmet, and Iran's willingness to conduct four strikes in six hours suggests Tehran does not view negotiations as imminent.
The article does not specify: number of missiles fired in this fourth volley, which systems intercepted them, whether any penetrated defenses, damage assessments, or whether this represents a change in Iranian targeting doctrine or simply continued pressure.
