Overview
This analysis compares the David's Sling, a Israel Mid-tier 40-300km system costing $1.0M per unit, against the Emad, an Iranian Guided MRBM costing $1.2M per unit. The cost-exchange ratio of 0.8:1 favors the defender — meaning interception is cheaper than the attacking munition.

Head-to-Head Analysis
Cost-Exchange Economics
The David's Sling costs $1.0M per unit while the Emad costs just $1.2M, creating a 0.8:1 cost-exchange ratio. Favorable for the defender — one of the few matchups where interception is cheaper than the threat.
The David's Sling is one of the rare cases where the defender has a cost advantage, with interception cheaper than the threat.
Inventory & Depletion
Coalition forces have approximately 180 David's Sling interceptors with annual production of 50 units. Iran maintains an estimated 200 Emad units.
Iran holds a 1:1 inventory advantage in this matchup.
Tactical Engagement
The David's Sling engages the Emad during the flight phase. With 1700km range, the Emad can be launched from deep within Iranian territory, complicating launch detection. Stunner dual-seeker. Upgraded for BMs.
The David's Sling is designed to counter threats like the Emad, but sustained engagement at 0.8:1 cost ratios creates long-term sustainability challenges.
Scenario Analysis
Mass salvo of Emad missiles
In a saturation attack using Emad systems, the David's Sling battery would need to engage multiple targets simultaneously. At $1.0M per interceptor, a salvo of 2 Emad missiles would cost $2.4M to launch but $2.0M to intercept.
Emad
Extended conflict (30+ days)
Over 30 days of sustained combat, the David's Sling inventory faces significant depletion pressure. Annual production of 50 units translates to just 0.1 per day — far below consumption rates during active operations. Meanwhile, Iran produces approximately 3.3 ballistic missiles and 6.7 drones per day.
Attacker (Iran) — production outpaces defender replenishment
Complementary Use
The David's Sling should be integrated into a layered defense architecture, not relied upon as a standalone solution against Emad 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 Emad matchup produces a 0.8:1 cost-exchange ratio favoring the defender. For sustained conflict planning, interceptor production ramp-up and cost-reduction programs are critical to maintaining defensive capability.
