PAC-3 CRI vs Zolfagar: Cost-Exchange Ratio & Combat Analysis
Compare

Overview
This analysis compares the PAC-3 CRI, a US Terminal (cost-red) system costing $3.5M per unit, against the Zolfagar, an Iranian SRBM costing $300K per unit. The cost-exchange ratio of 11.7:1 favors the attacker — meaning it costs the defender 11.7x more to intercept than the missile cost Iran to produce.

Head-to-Head Analysis
Cost-Exchange Economics
The PAC-3 CRI costs $3.5M per unit while the Zolfagar costs just $300K, creating a 11.7:1 cost-exchange ratio. Highly unfavorable for the defender. Extended engagements at this ratio are unsustainable. Iran can produce 11 Zolfagar units for the price of a single PAC-3 CRI interceptor.
The Zolfagar has a 11.7:1 cost advantage over the PAC-3 CRI. This asymmetry is a key factor in the conflict's economic sustainability.
Inventory & Depletion
Coalition forces have approximately 700 PAC-3 CRI interceptors with annual production of 200 units. Iran maintains an estimated 400 Zolfagar units. The PAC-3 CRI is already 50% depleted vs operational requirements.
Coalition holds an inventory advantage, but at 11.7:1 cost ratio, this is offset by economics.
Tactical Engagement
The PAC-3 CRI engages the Zolfagar during the terminal phase. At 700km range, the Zolfagar is primarily a medium-range threat. 90% of MSE capability at 83% cost.
The PAC-3 CRI is designed to counter threats like the Zolfagar, but sustained engagement at 11.7:1 cost ratios creates long-term sustainability challenges.
Scenario Analysis
Mass salvo of Zolfagar missiles
In a saturation attack using Zolfagar systems, the PAC-3 CRI battery would need to engage multiple targets simultaneously. At $3.5M per interceptor, a salvo of 4 Zolfagar missiles would cost $1.2M to launch but $14.0M to intercept.
Zolfagar
Extended conflict (30+ days)
Over 30 days of sustained combat, the PAC-3 CRI inventory faces significant depletion pressure. Annual production of 200 units translates to just 0.5 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 PAC-3 CRI should be integrated into a layered defense architecture, not relied upon as a standalone solution against Zolfagar 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 PAC-3 CRI interceptors for high-value targets.
Overall Verdict
The PAC-3 CRI vs Zolfagar matchup produces a 11.7:1 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.
