Seawolf is:
Faster - Bigger power plant and improvements in hull hydrodynamics.
Deeper Diving - Better hull materials. hull design better for deep submergence thanks to CAD. One of the design goals was to correct the lack of depth ability over the previous generation of SSN's. They wanted to at least regain the depth ability of the 637 class of SSN's.
Quieter - Lessons learned from all the previous boats are applied to the seawolf. From published reports, it is quieter at 'patrol speed' than a 688I is sitting next to the pier.
Sensors are approx the same sensor suite as a 688I
With that being said, the sensors may be of comparible quality, the computing power that is available to crunch on that data is far better on a seawolf. I have not set foot on a seawolf, but from the publically available data, there is a LOT more computer power in the seawolfs fire control system to make sense of everything.
