Operation Epic Fury Enters Sustained Phase as Iran Shifts to Drones

Air Campaign Enters Sustained Phase

WASHINGTON / TEHRAN — Nearly one month into Operation Epic Fury, the conflict between the United States and Iran has transitioned from an initial wave of strikes into a sustained, multi-domain campaign. U.S. and allied forces continue coordinated air operations targeting Iranian military infrastructure, missile systems, radar networks, and naval assets.

Operational updates indicate that thousands of targets have been struck since late February, including coastal installations linked to Iran’s control of strategic waterways such as the Strait of Hormuz. While some reported strikes on energy-related infrastructure have been paused, military and strategic objectives remain active. The focus remains on degrading Iran’s capacity to conduct missile and drone attacks and limiting its regional operational reach.

Iranian Response Emphasizes Drones and Regional Pressure

Iran’s retaliatory strategy has evolved as the conflict has progressed. Although the volume of ballistic missile launches has declined compared to the opening phase, Tehran has increased its reliance on drone operations and targeted strikes against regional bases and maritime assets.

Recent activity reflects a rise in drone deployments directed toward Gulf states and commercial shipping routes. Iranian officials have also claimed missile strikes against U.S. naval assets, including the USS Abraham Lincoln. U.S. defense officials state that attempted attacks were intercepted and did not result in confirmed damage.

The shift toward drones and distributed strikes suggests an effort to sustain pressure while managing missile inventories and avoiding large-scale escalatory triggers.

Reinforcements Signal Expanded Military Posture

A significant development in recent days has been the continued buildup of U.S. forces in the region. In addition to multiple carrier strike groups, deployments now include two Marine Expeditionary Units, elements of the 82nd Airborne Division, and additional naval and air assets.

These reinforcements bring the total U.S. personnel in the region to tens of thousands. Marine units introduce amphibious and ground-capable forces able to operate from sea-based platforms, expanding operational flexibility beyond air and naval strike missions. While no large-scale ground offensive has been announced, the presence of these forces broadens contingency options.

Sustainment Pressures and Munitions Use

The pace of operations has raised questions about long-term sustainment. Defense analysts note that missile defense interceptors and precision-guided munitions are being expended at a high rate. Thousands of weapons have reportedly been used in recent weeks, including systems designed to intercept Iranian missiles and drones.

If operational tempo remains constant, some analysts warn that inventories of key systems could face strain within weeks, underscoring the logistical demands of sustained high-intensity conflict.

Diplomatic Efforts Remain Stalled

Diplomatic initiatives have yet to produce a breakthrough. Iranian officials have rejected U.S.-backed ceasefire proposals, stating that any resolution would be determined on Tehran’s terms. Meanwhile, military planning continues for potential expanded strike phases and additional contingencies.

With combat operations ongoing and no formal de-escalation framework in place, the conflict remains active and fluid. The integration of airpower, naval deployments, missile defense, cyber operations, and ground-capable forces reflects a widening operational scope.

Despite sustained strikes and force buildups, neither side has achieved a decisive turning point. The conflict continues to evolve through incremental pressure, shifting tactics, and expanded military options across multiple domains.
