Aircraft Carrier Warfare: How Today’s Iran War Compares to Historic Naval Deployments

From World War II Armadas to Modern Carrier Strike Groups

As aircraft carriers converge around the war with Iran, many observers are asking the same question: how large is this naval buildup compared with past wars?

Aircraft carriers have been the centerpiece of global naval warfare since World War II, allowing countries to project airpower across oceans without relying on land bases. But the number of carriers deployed in a conflict—and the combat power they represent—has changed dramatically over time.

Understanding how today’s carrier deployments compare with past wars helps put the current naval buildup into perspective.

World War II: The Largest Carrier Armadas in History

Aircraft carriers emerged as the dominant naval weapon during World War II, replacing battleships as the primary means of projecting naval power.

Some of the largest carrier concentrations in history occurred during major Pacific battles.

At the Battle of the Philippine Sea, the United States deployed 15 fleet and light aircraft carriers as part of the massive Fast Carrier Task Force. Japan fielded nine carriers, bringing the total number of carriers in the battle to more than twenty.

Carrier aircraft from these fleets conducted thousands of sorties, destroying much of Japan’s naval aviation in what became known as the “Great Marianas Turkey Shoot.”

The scale of these carrier armadas has never been matched in modern warfare.

Cold War: Carriers as Global Deterrence

After World War II, aircraft carriers shifted from mass fleet battles to a role focused on global deterrence and rapid military response.

During the Cold War, the United States Navy maintained multiple carrier battle groups around the world to counter the Soviet Union.

Although the U.S. often operated 10 or more carriers globally, they were rarely concentrated in a single combat theater. Instead, carriers were distributed across the Atlantic, Pacific, and Mediterranean to maintain strategic balance.

Even so, carriers were frequently used in regional conflicts and crises, including:

• the Vietnam War, where several carriers operated simultaneously in the Gulf of Tonkin

• the Cuban Missile Crisis, when U.S. carrier groups helped enforce the naval quarantine of Cuba

Carriers became the backbone of American expeditionary warfare during this period.

The Gulf War: The Largest Modern Carrier Deployment

The largest carrier concentration in the Middle East occurred during the Gulf War.

During Operation Desert Storm, the United States deployed six aircraft carriers to the region. They operated in two main groups:

• Battle Force Zulu in the Persian Gulf

• Battle Force Yankee in the Red Sea

Aircraft from these carriers flew thousands of strike sorties against Iraqi forces, attacking air defenses, military infrastructure, and ground forces throughout the war.

The deployment remains the largest carrier concentration in the Middle East since World War II.

Post-9/11 Wars: Smaller but Highly Effective Carrier Fleets

In the wars that followed the September 11 attacks, carriers remained central to U.S. military operations, though the number deployed simultaneously was smaller.

During the early stages of the War in Afghanistan, carrier-based aircraft provided the majority of strike missions because nearby airbases were limited.

Similarly, the Iraq War saw several U.S. carriers supporting the initial air campaign.

Although fewer carriers were used compared with the Gulf War, their aircraft were significantly more capable thanks to precision-guided weapons and advanced targeting systems.

The Iran War: A Modern Carrier Buildup

Today’s conflict involving Iran is again drawing carrier forces into the region.

Two U.S. aircraft carriers—the USS Gerald R. Ford (CVN‑78) and USS Abraham Lincoln (CVN‑72)—are already operating near the theater of war.

Additional deployments could raise the total to five carriers if the USS George H. W. Bush (CVN‑77), the French carrier Charles de Gaulle (R91), and the British HMS Prince of Wales (R09) all join operations.

If this occurs, it would represent one of the largest carrier deployments in the region in decades, approaching—but still slightly below—the six-carrier fleet assembled during the Gulf War.

Why Modern Carriers Are More Powerful

Even though today’s fleets may include fewer carriers than in past wars, each ship carries far greater combat capability.

Modern carrier air wings include advanced aircraft such as:

• F-35 stealth fighters

• Rafale M multirole fighters

• electronic warfare aircraft

• airborne early-warning radar platforms

These aircraft use precision weapons and networked targeting systems that allow them to strike targets with far greater accuracy than the aircraft used in earlier wars.

As a result, a smaller number of carriers today can deliver combat power that rivals or exceeds much larger fleets from previous decades.

Comparing Carrier Deployments Across Modern Wars

A Symbol of Modern Naval Power

Aircraft carriers remain one of the most visible and powerful symbols of military strength.

Deploying multiple carriers to a region sends a clear message: the ability to launch sustained air operations, defend shipping lanes, and rapidly escalate if necessary.

While the current buildup around Iran does not yet match the largest carrier armadas of the twentieth century, it still represents one of the most significant naval deployments in the Middle East in decades.

As the war continues to evolve, the role of these carriers—and the scale of the fleet supporting them—may become one of the defining military factors in the conflict.
