Unfortunately, the end of the Cold War did not end the dangers that submariners faced, for the dangers of the sea are truly eternal.
Submariners continued to toil in daily obscurity until the loss of the Russian guided-missile submarine Kursk and the collision between the American attack submarine USS Greeneville and the Japanese school ship Ehime Maru thrust the submarine service back into the worldwide spotlight. Other accidents have gone unnoticed by the public, except for very brief periods.
