After building the USS Enterprise CVN-65, the navy went back to building conventional fossil fueled aircraft carriers. Congress thought that nuclear powered carriers were too expensive. Since a nuclear powered vessels can run at top speed for long distances without refueling, they are inherently more capable carriers than conventionally powered ones. With the USS Nimitz CVN-68, the USN finally went to all nuclear carriers. The Nimitz class has been the pattern ever since. Different ships in the class have various differences.
This is the USS Theodore Roosevelt CVN-71 of the Nimitz class. It is produced in 1:1250 scale by Carlos Marquadt and is model CMP-1017. Obviously, the model of a Nimitz class carrier is huge, even in 1:1250 scale. Aircraft for the deck would add additional color and variety to the model.
