Noise
 

Since Nautilus the US Navy has constantly worked on noise reduction. We have been quite successful at it.
What I would point out is there are some really quite subs, but weight that against the advantage of Nuclear power.
Fast, endurance, flexibility are some of them. A nuke boat can operate with a CVBG, or stalk other subs. Sonar 732 can be more specific on this, but I have read and been told a Ohio Class answering a standard bell can hardly be heard a 100 yards. I never operated against an Ohio so I can not offer first hand knowledge.
Nuclear power made subs truly independent of the out side environment. In 1964, on the Swordfish we submerged on may 15th and surfaced again on August 20th. The only thing every raised was periscope and radio mast. I don't know if we ventilated or not. Probably did because we were still using the old O2 candles back then.
Nukes are quiet, they are fast, and they can go for a long time. Let me tell you 90 plus days submerged is long enough, none of the super quiet subs can do that, not that they have a place in Naval warfare. The U.S. Navy is an offensive weapon and Nuke Boats are the best for that.

Good discussion,

P.S. In all fairness I never served on Diesel Boats so all my knowledge of them is from reading and talking. On I went out on one is Sub School, back when Moby Dick was a minnow.
