U.S. warns Iran major combat operations could resume if Gulf threats escalate.

The United States warned that American forces are fully prepared to resume major combat operations against Iran if Tehran threatens U.S. troops, commercial shipping, or regional stability during the ongoing “Project Freedom” mission in the Strait of Hormuz. The announcement, published by the U.S. Department of Defense on May 5, 2026, signals that Washington is ready to rapidly shift from maritime security operations to direct military action if tensions escalate in the Gulf.

U.S. Secretary of War Pete Hegseth stressed during a Pentagon briefing that the mission remains defensive, but U.S. forces are positioned to respond immediately to any Iranian escalation. The warning underscores the strategic importance of the Strait of Hormuz for global energy flows and reflects growing U.S. emphasis on deterrence, rapid-response capability, and protection of critical maritime trade routes.

“The U.S. President has been very clear about this. We prefer this to be a peaceful operation, but are locked and loaded to defend our people, our ships, our aircraft, and this mission without hesitation,” Hegseth stated, underscoring the increasingly tense military posture surrounding one of the world’s most strategic maritime chokepoints.

The warning comes as U.S. Central Command continues “Project Freedom,” a large-scale operation launched to restore commercial navigation through the Strait of Hormuz after repeated Iranian attacks against civilian shipping and regional infrastructure. According to Pentagon officials, American destroyers, fighter aircraft, helicopters, drones, and surveillance assets are currently deployed across the region to establish secure maritime transit corridors and deter further Iranian interference.

In and around the Strait of Hormuz, the United States has concentrated an extensive multinational-capable air and naval force that includes A-10 Thunderbolt II attack aircraft, F-15 Eagle fighters, F-16 Fighting Falcons, F/A-18 Super Hornets, fifth-generation F-35 stealth fighters, EA-18G Growler electronic warfare aircraft, RC-135 reconnaissance aircraft, KC-46 Pegasus and KC-135 Stratotanker aerial refueling aircraft, alongside numerous U.S. warships.

The naval deployment includes guided-missile destroyers, two carrier strike groups, an amphibious readiness group, and a Marine Expeditionary Unit, providing the United States with a layered capability for air superiority, electronic warfare, maritime strike operations, reconnaissance, force projection, and rapid-response amphibious operations throughout the Gulf region.

Chairman of the Joint Chiefs of Staff Gen. Dan Caine reinforced the message by stating that U.S. forces remain in a “three-point stance” and are fully prepared to resume broader combat operations if ordered by President Trump. U.S. officials also stressed that American restraint should not be interpreted as weakness, warning that any attack on U.S. forces or commercial vessels would trigger “overwhelming and devastating American firepower.”

Pentagon officials confirmed that more than 15,000 U.S. service members and over 100 aircraft are currently supporting the operation, which combines naval forces, combat aviation, airborne surveillance, drones, and integrated command-and-control systems to maintain freedom of navigation through the Strait of Hormuz. The deployment reflects Washington’s determination to secure international maritime commerce while simultaneously maintaining military pressure on Iran amid ongoing regional tensions.

Although U.S. officials continue to describe “Project Freedom” as a temporary and defensive mission intended to stabilize maritime traffic, the latest Pentagon statements clearly indicate that CENTCOM retains the capability to rapidly escalate operations if Iranian actions cross the threshold for renewed major combat.
