Interceptor Burn Rate & Depletion Analysis
Coalition missile defense interceptor stocks are being consumed at rates that far exceed peacetime production capacity. During Operation Epic Fury (Feb–Mar 2026), daily burn rates have reached levels that threaten critical depletion of high-end interceptors within weeks, not months.
Interceptor Depletion Table
Current inventory, Epic Fury daily burn rates, days until depletion (at sustained burn), annual production capacity, unit cost, and the daily production gap (burn minus daily production).
| System | Inventory | Burn Rate | Depletion | Annual Prod | Unit Cost | Daily Gap |
|---|---|---|---|---|---|---|
| THAAD | 384 | 20/day | 19 days | 96/yr | $12.7M | 19.7/day |
| SM-3 (all) | 414 | 12/day | 34 days | 66/yr | $27.9M | 11.8/day |
| PAC-3 MSE | 1,800 | 8/day | 225 days | 620/yr | $4.2M | 6.3/day |
| Arrow 3 | 65 | 4/day | 16 days | 30/yr | $3.0M | 3.9/day |
| Arrow 2 | 85 | 1.5/day | 56 days | 25/yr | $3.0M | 1.4/day |
| SM-6 | 750 | 6/day | 125 days | 165/yr | $4.9M | 5.5/day |
| Iron Dome | 1,800 | 60/day | 30 days | 500/yr | $80K | 58.6/day |
Key Findings
- THAAD: 384 interceptors remaining at 20/day burn rate = 19 days to depletion. Lockheed Martin produces only 96/year (target: 400/yr by 2029). At $12.7M per round, THAAD consumption costs $254M/day.
- SM-3: 414 total SM-3 (Block IIA + IB combined). At 12/day Epic Fury burn, depletion in 34 days. At $27.9M per round, the most expensive interceptor in the fleet.
- PAC-3 MSE: Already 75% depleted vs requirements. 1,800 remaining at 8/day. $9.8B contract placed Sep 2025 to accelerate production to 2,000/yr.
- Arrow-3: Israel's upper-tier BMD with only 65 interceptors. At 4/day, depletion in 16 days. Production tripled after WSJ report of stocks "running low."
Production vs Consumption
The core problem is structural: interceptor production was sized for peacetime deterrence, not sustained high-intensity combat. Even with emergency production ramps, it takes 18–24 months to expand manufacturing lines. The daily production gap column above shows how many interceptors are consumed per day net of production — all systems show negative trends during active operations.
Frequently Asked Questions
What is the THAAD interceptor burn rate?
During Operation Epic Fury, THAAD interceptors are consumed at approximately 20/day. With 384 remaining and annual production of only 96, this rate leads to depletion in approximately 19 days without production replenishment.
How fast are SM-3 interceptors being used?
SM-3 interceptors (Block IIA + IB) are consumed at 12/day during Epic Fury operations. Total inventory is 414 units. At $27.9M per round, SM-3 is the most expensive interceptor system in the coalition fleet.
Can interceptor production keep up with consumption?
No. All major interceptor systems show a daily production gap during sustained combat operations. Peacetime production was designed for deterrence stockpiling, not active consumption. Emergency contracts have been placed but manufacturing ramp-up takes 18-24 months.
Which interceptor system is most at risk?
Arrow-3 is most critical with only 65 interceptors and 16 days to depletion at Epic Fury rates. THAAD follows with 19 days. PAC-3 MSE is already 75% depleted vs requirements despite having the largest inventory.
