The United States Navy operates two distinct types of aircraft carriers: super aircraft carriers, large and equipped for long air dominance missions with the ability to launch heavy aircraft, and amphibious assault ships, smaller and adapted for rapid airborne operations. ground support with vertical landing and takeoff capabilities, ensuring flexibility and effectiveness in a variety of military operations.
The United States Navy operates not only traditional super aircraft carriers, but also has a fleet of amphibious assault ships. Both are essential, but perform functions different. With a total of 11 super aircraft carriers and nine amphibious assault ships, American naval power maintains critical versatility in its military operations.
The super aircraft carriers, with their imposing length of 332 meters, are true floating airports, equipped to launch large aircraft such as the F/A-18 Hornet and the E-2 Hawkeye. These ships are essential for long-term operations and air dominance, thanks to their vast decks that facilitate intensive and continuous air operations.
Amphibious assault ship decks serve primarily for vertical takeoff and landing aircraft
On the other hand, amphibious assault ships, slightly smaller at around 259 meters, are adapted for operations involving landings and immediate ground support. Its decks are mainly used for vertical takeoff and landing aircraft, such as the F-35B and the V-22 Osprey, making them ideal for rapid, direct support of ground forces and rescue operations.

Size directly influences the volume and, consequently, the operational efficiency of ships. The square-cube law explains that when increasing the dimensions of an object, its volume increases proportionally more than its surface. This means that a super aircraft carrier, despite being only 76 meters longer than an amphibious assault ship, has a significantly greater volumetric capacity. This greater volume allows supercarriers to move more efficiently and sustain prolonged operations without the need for frequent refueling.
Super aircraft carriers can carry up to 375.000 cubic feet of weaponry, providing autonomy for up to two weeks of continuous operations
In terms of cargo capacity, super aircraft carriers can carry up to 375.000 cubic feet of weaponry, providing autonomy for up to two weeks of continuous operations. In contrast, an amphibious assault ship, with significantly less storage capacity, would be capable of sustaining intensive combat for approximately a week without refueling.
Amphibious assault ships, in addition to their aerial duties, are equipped with internal docks that transport landing vehicles and support equipment, allowing for the rapid deployment of Marine forces. These ships are ideal for missions that require rapid response and operational flexibility, unlike super aircraft carriers, which are designed for air power projection and command of extensive naval operations.
Existence of two types of aircraft carriers in the United States Navy reflects an adaptive strategy
The existence of two types of aircraft carriers in the United States Navy reflects an adaptive strategy that seeks to maximize the operational effectiveness in different combat scenarios. While super aircraft carriers are essential for maintaining air supremacy and continuous large-scale support, amphibious assault ships offer agility and immediate support in situations that require rapid and effective intervention on the ground. The diversity of aircraft carriers, therefore, not only increases the Navy's responsiveness, but also ensures that the force can operate efficiently across a wide range of military missions.
