There is always a love for adventure in most men and the feelings must
            
 be the highest in a land of pioneers, the United  States;  and  this  spirit
            
 will naturally find its best expression in a situation where the unknown  is
            
 the highest - in the land filled with dark still sea waters. Americans  have
            
 had a historic association with the submarines and the fleet celebrated  its
            
 centenary in the year 2000, for which the preparations  had  been  going  on
            
 for a long time. The  first submarine of the  country  was  accepted  by  the
            
 Navy on a day in spring of the  year  1900.  This  ship  was  known  as  the
            
 submarine boat called USS Holland and is numbered as (SS 1). The  acceptance
            
 was of course after a lot of  trials.  These  were  so  extensive  that  the
            
 pioneer had to sell his shipyard to his battery supplier, and under the  new
            
 ownership the yard supplied a  large  number  of  ships  to  the  navy.  The
            
 demonstration trials were held off Mount Vernon on the  Potomac  River.  The
            
 submarine was only 54 foot long and was incapable  of  going  out  into  the
            
 open sea. The spirit of the submariner has always had this  strange  ongoing
            
 battle with the elements for  superiority  over  nature,  with  the  aid  of
            
 technology. (Fleet Ballistic Missile Submarines - SSBN)
            
       This may be said to be the principle problem and reflected in the form
            
 of improvement  of  underwater  endurance  and  performance.  This  is  more
            
 determined by the ship than by the individual. In the beginning this  caused
            
 a lot of difficulties in the design of  the  submarine  itself.  The  United
            
 States is a relatively young country  and  the   first  record  of  submarine
            
 activity is from the Nile Valley in Egypt. There we are  able  to  see  many
            
 wall paintings that show people hunting ducks with  spears  for  the  birds.
            
 They are not chasing them on land, but slowly moving up to  them  hidden  in
            
 the depths of...
