The Arleigh Burke destroyer weighs 10,000 tons and has 140,000 hp.
The Nimitz carrier weighs 100,000 tons and has 280,000 hp.
This seems very counter intuitive.
I find it confusing that a ship can weigh 10 times as much but only has 2 times the horsepower. I always thought if a ship weighed 10 times as much then maybe it should have 4 times the horsepower. I find this confusing.
Anyways lets assume these numbers are accurate.
Suppose a carrier never travels alone and is always escorted by 8 destroyers. Therefore one carrier battle group would have a combined power of 1,400,000 hp. That is 280,000 hp of nuclear power and 1,120,000 hp of diesel power. Look at it this way a carrier battle group has 20% hp of nuclear power and 80% hp of diesel power.
What am I getting at?
The fuel savings of going "nuclear" for a carrier seems very small considering it only makes up 20% of the battle group.
Am I onto something or am I missing something?
