I would love to see sources on that upgrade to 25k shp, yes the LM2500's design was capable of that but I have IIRC not seen any reference to the LM2500's on the Spruance being (much) more then 20000 shp. Such as change would likely also change propeller design, and the Spruance was as build already more powerful then needed for it's requirements (the original design had just 3 LM2500 in a more complex electrically coupled propulsion train) and IIRC the Perry's and the Tico's used the same gearboxes and LM2500 as used on the Spruance? So shouldn't that problem be a lot more widespread?It is perfectly possible to downrate turbines (might even make them more efficient in some cases) so even if the LM2500's were improved during the design process of the Spruance they could have been limited somewhat instead of running the propulsion train out of spec (this was for example done on the Dutch Tromp class, where the industry was unable to provide variable pitch propellers to handle the full power of the Olympus gas turbine at that point)
