Iron Dome vs Fateh-110: Cost-Exchange Ratio & Combat Analysis
Compare

3 min read
Overview
This analysis compares the Iron Dome, a Israel SHORAD system costing $80K per unit, against the Fateh-110, an Iranian SRBM costing $300K per unit. The cost-exchange ratio of 0.3:1 favors the defender — meaning interception is cheaper than the attacking munition. At Operation Epic Fury burn rates of 60/day, the Iron Dome inventory of 1800 units faces depletion in approximately 30 days. Short-range rocket/mortar/drone defense system with 90%+ intercept rate Solid-fueled SRBM family — Fateh-110/313/360 variants with 300-400km range

Head-to-Head Analysis
Cost-Exchange Economics
The Iron Dome costs $80K per unit while the Fateh-110 costs just $300K, creating a 0.3:1 cost-exchange ratio. Favorable for the defender — one of the few matchups where interception is cheaper than the threat.
The Iron Dome 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 1,800 Iron Dome interceptors with annual production of 500 units. Iran maintains an estimated 500 Fateh-110 units. At Operation Epic Fury burn rates of 60/day, the Iron Dome inventory of 1800 units faces depletion in approximately 30 days.
Coalition holds an inventory advantage, but at 0.3:1 cost ratio, this is offset by economics.
Tactical Engagement
The Iron Dome engages the Fateh-110 during the flight phase. At 400km range, the Fateh-110 is primarily a short-range threat. 5,000+ combat intercepts. 90%+ rate.
The Iron Dome is designed to counter threats like the Fateh-110, but sustained engagement at 0.3:1 cost ratios creates long-term sustainability challenges.
Scenario Analysis
Mass salvo of Fateh-110 missiles
In a saturation attack using Fateh-110 systems, the Iron Dome battery would need to engage multiple targets simultaneously. At $80K per interceptor, a salvo of 5 Fateh-110 missiles would cost $1.5M to launch but $400K to intercept.
Fateh-110
Extended conflict (30+ days)
Over 30 days of sustained combat, the Iron Dome inventory faces significant depletion pressure. Annual production of 500 units translates to just 1.4 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 Iron Dome should be integrated into a layered defense architecture, not relied upon as a standalone solution against Fateh-110 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 Iron Dome interceptors for high-value targets.
Overall Verdict
The Iron Dome vs Fateh-110 matchup produces a 0.3:1 cost-exchange ratio favoring the defender. For sustained conflict planning, interceptor production ramp-up and cost-reduction programs are critical to maintaining defensive capability.
