David's Sling vs Shahab-3: Cost-Exchange Ratio & Combat Analysis
Overview
This analysis compares the David's Sling, a Israel Mid-tier 40-300km system costing $1.0M per unit, against the Shahab-3, an Iranian MRBM backbone costing $750K per unit. The cost-exchange ratio of 1.3:1 favors the attacker — meaning it costs the defender 1.3x more to intercept than the missile cost Iran to produce. Mid-tier defense system with Stunner dual-seeker interceptor for 40-300km threats Iran's most numerous MRBM — liquid-fueled Nodong derivative, 1,300km range

Complementary Use
The David's Sling should be integrated into a layered defense architecture, not relied upon as a standalone solution against Shahab-3 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 David's Sling interceptors for high-value targets.
Overall Verdict
The David's Sling vs Shahab-3 matchup produces a 1.3:1 cost-exchange ratio favoring the attacker. For sustained conflict planning, interceptor production ramp-up and cost-reduction programs are critical to maintaining defensive capability.
