The US Navy experimented with putting a 5-bladed screw on a 688. Fast as an Alpha, and as noisy... Pulled the dam thing off rather quickly.

Fast forward 20 years and now you have Seawolf (SSN-21 class). As quiet at 20 knots as a 688i is at 5 knots... and faster than a 688. How much, I will not say.

I know it makes your patriotic bones rattle (no matter what country you are from) to say you have the fastest or deepest diving etc.. but in all practicalities it is just bravado... having the deepest diving has very little tactical value (there is an exception to that). Speed does, but if you are noisy as ox cart, it really does not matter anyway either...
