Navy’s new $12b aircraft carrier beset with performance problems

What??? That makes no sense. Comparing energy to power is like comparing distance to speed. They are related but not interchangeable.

Yes. People do not understand the difference between energy and power. I have tried to explain it, but it is usually a lost cause. Even some electricians and engineers I have talked to misuse the terms. The people who made this chart should know better!

Using their numbers, P = 1 x 10^5 kW, time = (17/60) hour, that is about 28,300 kWh of energy. At my cost of $0.12 per kWh, the energy would cost $3400 or about $170 for each of 20 aircraft launched.

Of course, their efficiency is not the same as a light plant, which is providing continuous energy output rather than intermittent output. Include in that maintenance, etc, and its going to raise the actual operating cost. Also, cranking that amount out on a carrier is probably quite a feat.

>>but there is a big jump from having a carrier and knowing how to go to war.<<

In case you haven’t noticed. Going to war is the easy part. We have forgotten how to WIN A WAR!

Perhaps.

It is never a bad idea to re-evaluate.

Winning has taken on new meanings, in the post Viet Nam era. We won twice with Iraq, but unlike in Japan and Germany there was no post war plan to “rebuild a nation” We rebuilt Panama but not Iraq. I wonder what will be the rule of thumb in a Pacific war in 50 years?
