Review of Run Silent Run Deep

I've served on the U BOOTS we got after the WAR from the Germans as " WAR damage " ,type SEVEN .type nine .type Twenty one .I'm now 81 ,and I know all about submarines .I let U- BOOT Kapitan Leutnants and Chief Engineers . I never Heard them Boasting " Frontal torpedo attacks " on destroyers . Totally unrealistic ,AIMING at a destroyer running at you at 40 knots with just the boa showing and his front Cannon firing at you is a stupid and suicide move :if you miss ,which is more than probable ,you get rammed because you have nô Time to dive at pericopic depth ( 13 meters at That Time ).All the more That the US Submarines were very slow to dive ,nothing to do with a TYPE SEVEN U BOOT which crash Dived in 24 seconds . As for depth charges ,they are " innocuous " if they explode above the submarine ,they break it's back if they explode below . The U BOOTS crash Dived to 100/150 meters to avoid the depth charges . When the explosions occur ,it's hell aboard ,and this is not shown in this film Interesting film ,but very poor as naval submarine warfare is concerned . I'm an experienced Naval Archhitect and Engineer ,not a Movie Man,and I was inches losing m'y Life aboard these marvelous WAR machines ,the most intricate ever !
