Overview
This analysis compares the David's Sling, a Israel Mid-tier 40-300km system costing $1.0M per unit, against the Shahed-136, an Iranian Attack drone costing $35K per unit. The cost-exchange ratio of 28.6:1 favors the attacker — meaning it costs the defender 28.6x more to intercept than the missile cost Iran to produce. Mid-tier defense system with Stunner dual-seeker interceptor for 40-300km threats Low-cost delta-wing loitering munition with 2,500km range — mass-produced for attrition warfare

Head-to-Head Analysis
Cost-Exchange Economics
The David's Sling costs $1.0M per unit while the Shahed-136 costs just $35K, creating a 28.6:1 cost-exchange ratio. Highly unfavorable for the defender. Extended engagements at this ratio are unsustainable. Iran can produce 28 Shahed-136 units for the price of a single David's Sling interceptor.
The Shahed-136 has a 28.6:1 cost advantage over the David's Sling. This asymmetry is a key factor in the conflict's economic sustainability.
Inventory & Depletion
Coalition forces have approximately 180 David's Sling interceptors with annual production of 50 units. Iran maintains an estimated 3,000 Shahed-136 units with high-volume production capacity.
Iran holds a 17:1 inventory advantage in this matchup.
Tactical Engagement
The David's Sling engages the Shahed-136 during the flight phase. With 2500km range, the Shahed-136 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 Shahed-136, but sustained engagement at 28.6:1 cost ratios creates long-term sustainability challenges.
Scenario Analysis
Mass salvo of Shahed-136 missiles
In a saturation attack using Shahed-136 systems, the David's Sling battery would need to engage multiple targets simultaneously. At $1.0M per interceptor, a salvo of 20 Shahed-136 missiles would cost $700K to launch but $20.0M to intercept.
Shahed-136
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 Shahed-136 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 Shahed-136 matchup produces a 28.6:1 cost-exchange ratio favoring the attacker. This is one of the most economically asymmetric engagements in modern warfare. For sustained conflict planning, interceptor production ramp-up and cost-reduction programs are critical to maintaining defensive capability.
