How the U.S. 'Low-Cost High-Volume' Warfare Doctrine Aims to Exhaust Iran and Potential Future Enemies
Summary
Operation Epic Fury (February–May 2026) revealed significant strain on U.S. guided munitions stockpiles and exposed vulnerabilities in allied confidence across Gulf nations, as Iran simultaneously leveraged its extensive loitering munitions and ballistic missile inventories to stress American and partner air defence systems. Despite diplomatic dialogues held in Pakistan and Switzerland, active hostilities between the U.S. and Iran have continued through smaller-scale, intermittent engagements. On July 12, 2026, CENTCOM marked a historic milestone by deploying Saronic Corsair unmanned surface vessels (USVs) in combat for the first time, targeting Iran's naval infrastructure at Bandar Abbas, alongside earlier combat debuts of the Low-Cost Uncrewed Combat Attack System (LUCAS) and the Precision Strike Missile (PrSM). These developments indicate the U.S. is deliberately mirroring Iran's asymmetric warfare tactics by incorporating cost-effective, scalable precision-strike systems drawn from lessons learned during the Russia-Ukraine War. This strategic pivot toward an "affordable mass" doctrine reflects a broader geostrategic shift, where the goal is not merely stockpile accumulation but rather the sustained ability to continuously replenish and deploy high volumes of lower-cost munitions to gradually wear down adversaries.
Key Takeaways
- 1. **Industrial Warfare Vulnerability Exposed:** Operation Epic Fury demonstrated that the U.S. guided munitions industrial base cannot yet replenish stockpiles at the pace demanded by high-intensity conflict, highlighting a critical strategic weakness requiring urgent reform
- 2. **Combat Debut of Next-Generation Systems:** The first operational use of Saronic Corsair USVs, LUCAS loitering munitions, and PrSM ballistic missiles signals the U.S. military's accelerating integration of lower-cost, high-impact weapons platforms into active combat operations
- 3. **Tactical Mirroring of Adversary Strategies:** The U.S. is deliberately adopting warfighting approaches pioneered by Iran, Russia, and Ukraine — combining loitering munitions, conventional ballistic missiles, and low-cost cruise missiles to create scalable, affordable precision-strike capacity
- 4. **Allied Confidence at Risk:** Sustained Iranian pressure on Gulf partner air defence systems has begun eroding political confidence among key regional allies including Saudi Arabia, UAE, and Qatar, creating potential fractures in U.S. strategic partnerships in the Middle East
- 5. **'Affordable Mass' as an Attrition Strategy:** The overarching U.S. strategic objective appears to be leveraging continuous, cost-effective munitions production to sustain prolonged pressure on adversaries, prioritising industrial endurance and replenishment speed over singular overwhelming force
