Quite interesting indeed. I'm most interested in the submarines and technology involved in performing such operations. How do they operate? what modifications are needed? what computing platforms do they possess? That being said, I really like the idea of submarine super computing platforms. Not because it brings to life the inner Tom Clancy, but knowing that a small part of the idea may present some kind of practical utility in the world of clandestine operation.

These are submarine cables (that is, cables installed under the sea) not cables installed or used by submarine boats.

How are submarine cables installed?

[wiml]

By surface ships. Near shore they use a towed plough to bury the cable, away from shore they just unreel the cable and let it lie on the seafloor.

The tapping of this particular cable happens on land with the paid aid of Cable&Wireless.
