Arrow 2 vs Khorramshahr-4: Cost-Exchange Ratio & Combat Analysis
Overview
This analysis compares the Arrow 2, a Israel Endo-atmo BMD system costing $3.0M per unit, against the Khorramshahr-4, an Iranian Heavy MRBM costing $2.5M per unit. The cost-exchange ratio of 1.2:1 favors the attacker — meaning it costs the defender 1.2x more to intercept than the missile cost Iran to produce. At Operation Epic Fury burn rates of 1.5/day, the Arrow 2 inventory of 85 units faces depletion in approximately 56 days. Endo-atmospheric interceptor for medium-range ballistic missiles, combat-proven Iran's heaviest MRBM — liquid-fueled, 3,000km range, 1,500kg warhead

Complementary Use
The Arrow 2 should be integrated into a layered defense architecture, not relied upon as a standalone solution against Khorramshahr-4 threats. Cost-effective lower-tier systems (Iron Dome at $80K, or Iron Beam laser at $2/shot) should handle cheaper threats when possible, preserving expensive Arrow 2 interceptors for high-value targets.
Overall Verdict
The Arrow 2 vs Khorramshahr-4 matchup produces a 1.2:1 cost-exchange ratio favoring the attacker. For sustained conflict planning, interceptor production ramp-up and cost-reduction programs are critical to maintaining defensive capability.
