Grabbing the laser concept. How much energy would require to effectively use a laser beam underwater? How much energy would it require and possible effective range?

The thing with lasers was initially to serve as weapons. But if that is simply too ridiculous I can just use them as short distance defense lasers to pop incoming torpedoes.

As for the energy shields. Could energy be used over the sub's armor to increase its toughness? I don't know, something like holding the armor together by generating a strong magnetic field?

This would also play as a strategic role, because when the energy shield would be switched on, the sub could be easily located.

USN was developing some short of "shield" system to defeat shaped charge warheads of ASCMs. I don't have time to search it out now but if I remember correctly it was being considered for Ford class CVNs. Propably you could use that for ideas.
