   Due  to  the  aircraft  carrier  very  vulnerable  and  valuable  target  for  submarines .
Protection of  carrier  cannot  depend on acoustic  or  magnetic method .
 Under sea  manned  vehicle whic surrounds carrier from  bottom  to  near  in  enough  distance  with  or  without  cable  to get optic  vision  will be  future  of  carrier  protection,plus  will  work  as a  shield just  in case  shoot.
Other wise  carrier  function  easily  can be get paralyzed

Hans Island is Canadian, not Danish!

Manned undersea vehicles are called submarines. There is typically one or more already assigned to each carrier group. You need high speeds and high endurance to keep up with the carrier, so the submarines will have to be nuclear. How many do you think are needed for your scheme?
The primary underwater sensor is acoustic, mostly passive listening but occasionally active sonar. Magnet sensors are short ranged and only useful mounted on aircraft to confirm a faint target. If you have some alternative sensor technology to offer, please say so and supply a link to the source document.
Fiber optic cables have major problems at speeds greater dead slow because of the drag of the water. The only scheme so far that can deal with high speeds uses a disposable FOC that very thin and light weight so it floats in the water and is unreeled from both ends to avoid any tension. Maximum cable length is probably less than 20km.

I would think that some developments in subsurface sensory technology are kept away from the public domain, there's certainly a lot of signature classes involved (such as the surface effects of submerged passage), all of which have to be managed - that's not in any way meant to allude to some sort of super-secret magic-bullet detection mechanism because that gets into the wild-speculation of loon sites like ATS where the absense of a given thing is taken as evidence of its existence : ) nevertheless systems entering LRIP like the AN/AES-1 indicate that there's certainly plenty of research and investment taking place in relatively exotic means of detecting subsurface threats.
