Introduction
Earlier this week, the United States accelerated the deployment of the USS Abraham Lincoln (CVN-72) and its carrier battle group to the Middle East – an operation which was already in progress to relieve the USS Theodore Roosevelt (CVN-71) and its own battle group of escorting warships, who have been on station in the region for months – in response to signs that the increasingly unstable regime in Iran may attempt to significantly widen its proxy war against the state of Israel which began on October 7 of last year.
The Good Ol’ Days
The origin of the aircraft carrier battle group takes its origins from the world-spanning naval warfare of World War II, primarily from its operations in the Pacific Ocean. The devastating Japanese attack on Pearl Harbor, on December 7th, 1941, demonstrated the power of carrier-based aviation and the vulnerability of battleships, marking a fundamental shift in naval strategy, as the Imperial Japanese Navy destroyed the United States Navy’s main battle force in the attack. The United States Navy – stripped of its battleship fleet by the sneak attack on its Hawaiian base, and whose Asiatic Fleet was functionally neutralized in the opening stages of the war by staggeringly unbelievable levels of incompetence and mismanagement – was forced to continue the fight with only three aircraft carriers, something it had never seriously considered as a possibility.

As the war raged on, the U.S. Navy quickly adapted, forming diverse, multi-ship task forces centered on its massive aircraft carriers. The battles of the Coral Sea and Midway in 1942 proved the effectiveness of this approach, with American carriers dealing a decisive blow to the Japanese fleet, while remaining largely protected by much smaller destroyers and destroyer-escorts, which both shot down attacking Japanese aircraft, and sometimes absorbed bombs and torpedoes meant for the carriers. As the war progressed, these carrier task forces became increasingly sophisticated, with hard-learned doctrine and techniques using destroyers primarily for anti-submarine warfare and cruisers studded with heavy automatic cannons for air defense, even at close range.

Into the Cold
In the post-war era, the advent of jet aircraft and guided missiles led to further refinements to both aircraft carriers themselves, but also in their organization and tactics. The introduction of the angled flight deck and steam catapults (these are now being replaced with electromagnetic catapults on the new Gerald R. Ford-class carriers) in the 1950s enhanced carrier operations, while the development of guided missile destroyers and cruisers improved the group’s air defense capabilities, at least in theory. Modern navies, however, would get a severe reality check in 1982, as the very modern British Royal Navy was badly hammered by the second-tier air force of Argentina in the savage (especially allowing for its relatively small size) Battle of San Carlos, causing a sobering reassessment by all navies of their own capabilities and tactics. (On a historical side note, the Falklands War also saw the destruction of the ARA General Belgrano, the former USS Phoenix (CL-46), a Brooklyn-class cruiser from World War 2, which had survived the Pearl Harbor attack, to be sunk by a British attack submarine some forty years later.)

The Cold War saw the carrier battle group evolve into one of – if not the primary – key instruments of power projection. The nuclear-powered USS Enterprise (CVN-65), commissioned in 1961, heralded a new era of endurance for carrier operations. However, this would be tempered with the realization that while the range of the carrier itself was now measured in decades, instead of miles, it was still restricted by the ranges of its gas-turbine engined escort vessels, and the constant need for resupply of everything from food to bombs, spare parts and fuel for its aircraft wing. The development of the Aegis combat system in the 1980s (and its associated ballistic missile defense component) would significantly enhance the group’s air defense capabilities, while continuous development of anti-submarine and anti-mine technologies further protected the carrier and its escorts. These capabilities did not come without cost, however: hard lessons were learned from the attacks on the USS Stark, the USS Samuel B. Roberts, and the bombing of the USS Cole. These lessons continue to be learned, but the takeaway is that naval warfare – like all warfare – is not a video game, despite breathlessly giddy news stories to the contrary.
In the realm of anti-submarine warfare, the US Navy pioneered the modern use of armed combat drones in warfare, when it deployed the QH-50 DASH (Drone Anti-Submarine Helicopter), built by Gyrodyne, in 1959.

The Dawn of the Millennium and the GWOT
The post-Cold War period has seen carrier battle groups involved in numerous conflicts, from the 1990-91 Gulf War to operations in Afghanistan and Iraq. The groups have also played crucial roles in humanitarian assistance and disaster relief missions. Today’s carrier battle groups, while retaining their core structure developed over some fifty years, continue to evolve to meet new challenges. The integration of stealth aircraft, more advanced unmanned systems, and advanced, internet-based networking and cyberwar capabilities ensures that the carrier battle group will remain a fundamental cornerstone of naval power projection for the rest of the 21st Century.
Laying at the heart of the United States Navy’s global power projection capabilities, the carrier battle group (CVBG), also known as a carrier strike group (CSG) is a formidable assembly of warships and aircraft, centered around a nuclear-powered aircraft carrier, representing one of the most potent concentrations of military might ever to sail the world’s oceans. Usually comprising an aircraft carrier, a single guided missile cruiser for air defense, at least two LAMPS-capable warships (focusing on anti-submarine and surface warfare), and one or two anti-submarine destroyers or frigates, such battle groups frequently deploy more combat power than that possessed by most individual nations in the world.
The cornerstone of any carrier battle group is the aircraft carrier itself. As of 2024, the US Navy operates eleven nuclear-powered carriers, primarily of the Nimitz class, with the newer Gerald R. Ford class gradually being introduced into service. These floating airfields, crewed by between 4,000 and 5,000 sailors, displace approximately 100,000 tons and can carry an air wing of 60-75 aircraft.
The air wing of a 21st Century US aircraft carrier typically consists of:
- F/A-18 E/F Super Hornets: Multirole fighters capable of air superiority and strike missions.
- EA-18G Growlers: Electronic warfare aircraft for jamming enemy radar and communications.
- E-2D Hawkeyes: Airborne early warning and control aircraft.
- MH-60R/S Seahawk helicopters: For anti-submarine warfare, search and rescue, and utility missions.
- F-35C Lightning II: The Navy’s newest stealth multirole fighter, gradually being integrated into carrier air wings.

Surrounding the carrier are several Aegis-equipped guided missile cruisers and destroyers. These ships form a protective screen around the carrier and provide a wide range of capabilities:
- Ticonderoga class cruisers: Usually one or two per battle group, these ships specialize in air defense but are also capable of land attack and anti-ship warfare.
- Arleigh Burke class destroyers: Typically three to four per group, these versatile warships can perform anti-air, anti-surface, and anti-submarine warfare missions.
Both classes of ships are equipped with the Aegis combat system, which integrates powerful radars with various close-in and long-range weapon systems, allowing for sophisticated air and missile defense capabilities.
Although not always visible, one or two nuclear-powered attack submarines often operate in conjunction with a carrier battle group. These could be Los Angeles-, Virginia-, or Seawolf-class nuclear-powered submarines. Their primary roles include:
- Gathering intelligence
- Providing an unseen protective screen against enemy submarines
- Potential land-attack capabilities with Tomahawk cruise missiles
A carrier battle group also includes several support ships crucial for sustained operations:
- Supply ships: Usually one or two fast combat support ships (T-AOE) or a combination of fleet oilers (T-AO) and dry cargo ships (T-AKE) to replenish fuel, ammunition, and supplies.
- Hospital ships: While not typically part of the regular battle group, these can be attached for humanitarian missions or in anticipation of major combat operations.

An entire battle group, such as that outlined above, is under the command of a Rear Admiral (lower half), who typically serves as the Commander, Carrier Strike Group (CCSG). The CCSG and their staff coordinate the activities of all ships and aircraft in the group, ensuring they work together as a cohesive fighting unit.
A fully equipped US carrier battle group is ideally positioned to:
- Project power far from American shores, with the ability to strike targets hundreds of miles inland.
- Establish air superiority over a wide area.
- Conduct sustained air operations, launching over 100 sorties per day.
- Provide a visible deterrent to potential adversaries.
- Respond rapidly to crises anywhere in the world.
- Conduct humanitarian assistance and disaster relief operations.
The versatility of the carrier battle group allows it to transition quickly from peacetime presence to crisis response to full-scale war fighting. This is no more true than in its mission of supporting assault landings by combat units (MAGTF’s) of the United States Marine Corps, which remains a part of the Department of the Navy. The US Navy’s ten Amphibious Ready Groups are able to quickly insert up to 6,000 US Marines quickly, at multiple points along a hostile shoreline, ranging well inland, if necessary…as long as the naval squadron can get to the area quickly enough – hence, the acceleration of the USS Abraham Lincoln and her CVBG to the Levant.
As of 2024, the US Navy continues to adapt its carrier battle groups to meet evolving threats:
- Anti-ship ballistic missiles: The development of these weapons, particularly by China, has led to increased emphasis on integrated air and missile defense capabilities.
- Unmanned systems: The Navy continues to explore the integration of unmanned aerial, surface, and undersea vehicles to extend the reach and capabilities of the battle group.
- Cyber warfare: Increased focus on protecting the battle group’s networks and exploiting adversary vulnerabilities in the digital domain.
- Distributed lethality: Spreading offensive capabilities across more platforms in the battle group to complicate enemy targeting.
Conclusion
The Navy is continuously evolving the concept of the carrier battle group. Some areas of focus include:
- The integration of directed energy weapons for close-in defense.
- Development of long-range anti-ship missiles to counter peer competitors.
- Exploration of smaller, more numerous carriers to distribute capabilities.
- Enhanced networking capabilities to better integrate with joint and allied forces.
The US carrier battle group remains a cornerstone of American military power projection, and will continue to do so well into the 21st Century, and likely beyond. Its ability to bring a flexible, sustained, and potent military presence to any region of the world makes it a unique and invaluable strategic asset. As geopolitical tensions and technological advancements continue to shape the global security landscape, and as unrest continues to disrupt the trade vital to the modern world, the carrier battle group will continue to evolve, maintaining its role as a key instrument of US national security policy, as well as protecting the civilized world at large.
