US expands to three aircraft carriers as USS George H.W. Bush joins operation Epic Fury against Iran.

On March 31, 2026, the George H.W. Bush Carrier Strike Group deployed from Norfolk toward the Middle East, reinforcing U.S. naval power amid escalating operations against Iran.

The move places additional strike capacity within immediate reach of the region at a critical moment. The deployment comes as the USS Gerald R. Ford remains sidelined for repairs following a fire, while the USS Abraham Lincoln continues operations in the Arabian Sea. Together, these movements position the United States to sustain two to three carriers within operational reach, signaling credible escalation capacity despite uncertainty around Ford’s readiness.

The Carrier Strike Group 10 is currently organized around the USS George H.W. Bush (CVN-77), a Nimitz-class aircraft carrier displacing more than 100,000 tons and powered by two nuclear reactors, enabling multi-year endurance without refueling. Escort elements consist of three Arleigh Burke-class destroyers: USS Ross (DDG-71), USS Donald Cook (DDG-75), and USS Mason (DDG-87), with the latter designated as the Air and Missile Defense Commander responsible for coordinating defense against ballistic and cruise missiles. Personnel assigned exceed 5,000, including ship’s company, air wing, and command staff, forming a self-contained naval force capable of sustained air defense and strike missions, as well as anti-submarine warfare. 

Carrier Air Wing 7, embarked aboard the carrier, includes nine squadrons totaling several dozen aircraft across strike, escort, and surveillance, structured to support continuous sortie generation. Strike Fighter Squadrons VFA-83, VFA-103, VFA-105, and VFA-131 operate F/A-18E/F fighters for strike missions and air-to-air engagements. Electronic Attack Squadron VAQ-140 operates EA-18G Growler jets equipped for radar jamming and suppression of air defense systems. Airborne Command and Control Squadron VAW-116 operates E-2D Hawkeye aircraft to track multiple airborne and surface targets simultaneously. Rotary-wing units HSC-5 and HSM-46 operate MH-60S and MH-60R helicopters for logistics, anti-submarine warfare, and maritime strike missions.

Fleet Logistics Multi-Mission Squadron VRM-40 operates the CMV-22B Osprey, which replaces the C-2 Greyhound for carrier onboard delivery in its first operational use in an East Coast carrier group. The carrier’s ability to conduct sustained air operations is a key advantage in missions against Iran, where regional basing access may be constrained. The air wing can conduct strike missions against Iranian assets such as missile factories and naval bases, as well as mobile targets including naval vessels and missile systems. Continuous flight operations allow the generation of multiple strike packages per day, enabling persistent pressure. The carrier’s mobility allows repositioning across operational areas, including the eastern Mediterranean, Red Sea, and Arabian Sea, within days.

Integration with other carrier strike groups increases sortie capacity and operational redundancy. The carrier also supports maritime security operations, including the escort of commercial shipping through the Strait of Hormuz by its escort vessels. Preparation for the USS George H.W. Bush deployment included completion of COMPTUEX, which validated the integration of all strike group components. Following this certification, additional maintenance work was conducted over a period of about 25 days to address final system requirements and ensure full redundancy across propulsion, combat, and aviation systems. Coordination between ship personnel and the Naval Sea Systems Command focused on eliminating single points of failure before the deployment, which was rumoured to have been scheduled since early February.

Crew readiness included an intensive training cycle followed by a short leave period immediately before embarkation to manage fatigue. The deployment also required integration of new logistics procedures associated with the CMV-22B Osprey, including deck handling and supply chain adjustments. The final preparation phase ensured that all systems were operational without requiring further modifications after departure, indicating that the strike group can enter high-intensity operations without delay. Additional U.S. naval assets in the Middle East now include independent destroyers operating in the Arabian Sea and an amphibious ready group centered on USS Tripoli with about 3,500 personnel.

The Bush strike group may be tasked to reinforce these forces or relieve units that have exceeded standard deployment durations, such as the USS Gerald R. Ford. The stated operational model described by US Navy officials compares the group to a fire response unit, deployed without a fixed target but ready to respond to emerging crises. However, even if the absence of a declared destination is said to preserve flexibility, it is now certain that the USS George H.W. Bush is heading for the Middle East, just over a month after the first rumours on this subject. The potential deployment of three U.S. aircraft carrier strike groups in the same theater could produce a combined sustained output of 300 to 360 sorties per day, with surge capacity exceeding 600 sorties over short periods.

Operationally, three carriers positioned around Iran create a distributed strike architecture covering the eastern Mediterranean, Red Sea, and Arabian Sea, increasing the efficiency of the 180 to 210 aircraft distributed across three air wings. The naval escorts accompanying each carrier significantly expand the overall firepower available. Each escort ship typically carries 90 to 122 launch cells, and with three strike groups, the total number of launch cells can exceed 800 to 1,000, loaded with Tomahawk land-attack cruise missiles, enabling simultaneous large-scale strikes independent of aircraft operations. It also enhances defensive coverage against ballistic missiles and drones through integrated air and missile defense systems.

However, the ambiguity between the Bush and the USS Gerald R. Ford remains, as the Ford’s operations were temporarily affected by a fire in a laundry compartment, which required repairs and led to a short operational pause. Chief of Naval Operations Daryl Caudle indicated that the deployment of the Ford could extend into an 11th month while also noting that the carrier would return to station following repairs before eventually heading home, a statement which does not formally rule out a return to the Middle East, as sources diverge on this subject. Indeed, at the time of the Bush deployment, the Ford carrier strike group remained deployed against Iran. The Bush may initially operate alongside the Ford, increasing available airpower and operational coverage. A transition to replacement, however, could occur if the Ford returns to the station following the completion of its repairs in Croatia.
