594 TOUGH! 

Coming Soon 594 TOUGH!  

The sailors who served aboard them, either loved them or 
hated them for this trait, but the fact that they endured as frontline, 
first rate fast attack boats right up through their retirement, gave real 
meaning to the phrase ”594 tough.” This phrase symbolized both a
respect or hatred for a class of submarines, that like a wild animal, if 
not tamed could bite the men who sailed in them, just as easily as 
their Soviet prey; indeed as mentioned one crew paid the ultimate 
sacrifice. Nevertheless, the phrase also symbolizes the type of men 
who went to sea in these boats and carried out hard assignments that 
very few in the US Military could handle. So whether referring 
submarine or sailor, they were 594 TOUGH
