the only torpedo tube variant that I know of is 4 650 and 4 533, that gives the CO a great deal of weapons versatility. The weapons load is always an
issue with submarines, as they can carry only a few "rounds". The design of the Akula and Sierra are different, but mechanically similar, as I
understand it. The major difference was the material used for the hull, titanium vs steel. The Akula was optimized for smooth water flow, the
blockier Sierra, tho lighter because of the use of titanium, is slightly faster and noisier when moving at higher speeds. And noise is the bane of
the silent service. The Akula and Akula 2 are very good boats, and limited only by the crews.
