Aircraft carriers have become an integral part of a good navy. In fact, a navy is not considered good enough if it does not have aircraft carriers.

No wonder, the United States plans to build 10 Gerard Ford-class aircraft carriers, which can serve up to 50 years and replace 10 commissioned ships. The US will commission the first Ford-class carrier in 2014 and the last in 2048, which will help it maintain its dominance in oceans.

In comparison, China still lacks some major weaponry such as long-range strategic bombers, heavy transport aircraft and aircraft carriers. The country is still waiting for its first aircraft carrier to turn its naval defense capability from green water to blue water.
