Having spent a couple of years on a conventional (ie-oil fired boilers making steam) aircraft carrier, I can attest to the power of stream. Both of the ships I served on used dry steam at 1200 psi and around 975 degrees to power them. The Pratt (DDG-44) had 4 boilers and two main engines, and the America (CV-66) Had 8 boilers and 4 main engines.
Think about a vessel weighing in around 84,000 long tons or somewhere around 188,160,000 (188 million, one hundred and sixty thousand) pounds traveling right at 40 MPH. That's the fastest I can remember ever going on the America and at the time I was standing throttle watch in the #4 main machinery room. Our boilers were doing all they could, and the main engines were in overdrive, so to speak. Basically we were injecting full pressure 1200 psi main steam into the middle of the turbine instead of letting it go all the way through like it normaly did. Talk about something to see, the rooster tail thrown up by the old girl running that fast was impressive on a HUGE scale, to say the least.
