Premieres Monday, March 5 at 8 p.m. to kick off  Sub Week, featuring five days of the best "run silent, run deep" programs around!

From humble beginnings, submarines quickly evolved into the most sophisticated and powerful weapons of war ever devised.  Whether patiently stalking their prey in two World Wars or carrying devastating nuclear missiles as a deterrent in the Cold War, these hunters of the deep have played an often unseen but crucial role in the conflicts of the 20th century.  From the unexpectedly small to the terrifyingly huge, this program features some of the most innovative and ambitious weapon systems of the past 100 years. Based on scientific analyses, expert opinion, audience polls and technical comparison, we construct a five-point matrix to rank the TOP TEN SUBMARINES of all time.

CHECK OUT THE FINALISTS!

Be sure to tune in on Monday, March 5 at 8 p.m. ET/PT to find out which sub takes top honors!
