THAAD vs Ghadr-110: Cost-Exchange Ratio & Combat Analysis
Compare

3 min read
Overview
This analysis compares the THAAD, a US Terminal high-alt system costing $12.7M per unit, against the Ghadr-110, an Iranian Extended Shahab costing $850K per unit. The cost-exchange ratio of 14.9:1 favors the attacker — meaning it costs the defender 14.9x more to intercept than the missile cost Iran to produce. At Operation Epic Fury burn rates of 20/day, the THAAD inventory of 384 units faces depletion in approximately 19 days.

Head-to-Head Analysis
Cost-Exchange Economics
The THAAD costs $12.7M per unit while the Ghadr-110 costs just $850K, creating a 14.9:1 cost-exchange ratio. Highly unfavorable for the defender. Extended engagements at this ratio are unsustainable. Iran can produce 14 Ghadr-110 units for the price of a single THAAD interceptor.
The Ghadr-110 has a 14.9:1 cost advantage over the THAAD. This asymmetry is a key factor in the conflict's economic sustainability.
Inventory & Depletion
Coalition forces have approximately 384 THAAD interceptors with annual production of 96 units. Iran maintains an estimated 300 Ghadr-110 units. The THAAD is already 25% depleted vs operational requirements. At Operation Epic Fury burn rates of 20/day, the THAAD inventory of 384 units faces depletion in approximately 19 days.
Coalition holds an inventory advantage, but at 14.9:1 cost ratio, this is offset by economics.
Tactical Engagement
The THAAD engages the Ghadr-110 during the terminal phase. With 2000km range, the Ghadr-110 can be launched from deep within Iranian territory, complicating launch detection. CSIS Dec 2025: 534 pre-June, ~150 fired Jun '25 → ~384 remaining. Target: 400/yr by 2029.
The THAAD is designed to counter threats like the Ghadr-110, but sustained engagement at 14.9:1 cost ratios creates long-term sustainability challenges.
Scenario Analysis
Mass salvo of Ghadr-110 missiles
In a saturation attack using Ghadr-110 systems, the THAAD battery would need to engage multiple targets simultaneously. At $12.7M per interceptor, a salvo of 3 Ghadr-110 missiles would cost $2.5M to launch but $38.1M to intercept.
Ghadr-110
Extended conflict (30+ days)
Over 30 days of sustained combat, the THAAD inventory faces significant depletion pressure. Annual production of 96 units translates to just 0.3 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 THAAD should be integrated into a layered defense architecture, not relied upon as a standalone solution against Ghadr-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 THAAD interceptors for high-value targets.
Overall Verdict
The THAAD vs Ghadr-110 matchup produces a 14.9:1 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.
