What new capability was introduced to aircraft carriers that utilized nuclear power?

The introduction of nuclear power to aircraft carriers fundamentally changed their operational capabilities, particularly in terms of deployment duration. With nuclear reactors as their power source, these carriers can operate for extended periods without the need to refuel, which is a significant limitation for conventionally powered vessels that rely on fossil fuels. This capability allows nuclear-powered aircraft carriers to remain at sea for months, supporting sustained operations and missions without the interruptions that would typically be required for refueling.

Increased speed, while a possible advantage due to improved propulsion systems, is not the primary benefit of nuclear power compared to conventional engines. The ability to deploy larger aircraft is also influenced more by the design and configuration of the carriers themselves rather than their power source. Enhanced visibility systems are crucial for navigation and combat, but they are typically developed independently of the type of power used to propel the ship. Thus, the most significant advancement directly linked to nuclear power in aircraft carriers is indeed the capability for longer deployment durations.
