Not a BB question but I know and respect the engineering expertise that frequents this forum so please forgive me for intruding.

When it comes to engineering Im about as smart as a box of rocks. LOL

What are the reasons the Brits used two shaft geared turbines paired with two boilers for their "C"/Battle/Daring class destroyers but the USN used two geared turbines paired with four boilers for the Fletcher/Sumner/Gearing classes?

Does it have to do with shaft horsepower?

The USN ships had 60000 SHP the RN ships had 40000/50000/54000 respectively.

My next question will probably get me slammed but...

Would the Knox class frigates been able to have easilly/economically/space wise incorporated another shaft and geared turbine and with the same or different boilers realised increased speed to 29/30 kts or better?

How would it effect endurance?

I really like these ships except for a couple issues but mostly for being saddled with one screw and one geared turbine.

Thanks in advance for any info, thoughts or direction.
