The very low frequency radio network described by tekigm!dand is known as
the ELF grid.  It will permit reliable communication with submarines, but 
(naturally) at a very low data rate.  I recall reading that it is being
constructed in the north part of Wisconsin (could be wrong here).

Another submarine communication system being studied involved placing
blue-green lasers on satellites.  There are still technical problems.
Also political problems:  is this the dreaded "militarization of space?"

(Side note:  the horrible "military" payloads carried on the Shuttle 
will serve a similar purpose.  They are for navigation, communication, or
observation.  No weapons so far.)
