Answer:

As a result, the submarines are capable of diving to depths of up to two thousand feet, and crush depth estimates run from 2,400 to 3,000 feet. At 353 feet, Seawolf subs were designed to be slightly shorter than their predecessors, by just seven feet, but with a twenty percent wider beam, making them forty feet wide.
