decommission status on standby. after that, in '63 she was turned into an ssk, which is submarine hunter killer, the navy realized the submarines made in the war so they converted her into a platform that would primary mission is to look for other submarines so they had to add a lot of sonar equipment and reconfigure her. you can see that the deck is flat. a lot of people are taken by that. but the original configuration of the sub now is not what it was during the war. she had a different sail that surroundedconning tower that had bigger guns, three to five inch guns and that was used for making surface attacks. but this boat primarily ran on the surface. if you submerged this vessel after a full battery charge which takes about six to eight hours and then you went underwater, which a well-trained crew could submerge this boat in

under a minute you would only last about 45 minutes. >> they sank 1,178 japanese merchant ships. 214 japanese combat vessels. two-thirds of their merchant fleet. one-third of their navy. >> we're in the forward torpedo room. you'll see a couple of torpedo tubes in front of me. there's two down below in the deck. during the war there was two on top. so originally she had six torpedo tubes but after the reconfiguration to make this vessel a hunter killer, they had to remove the top two tubes so they could install on the exterior of that bulkhead hydrophones to include more sonar equipment to make it one

that is capable of listening further distances one of the interesting factors about submarine life is the forward crew and after crew would compete who could reload a torpedo faster. it was back in those days they had a -- they're mechanical advantage was block and tackle which now days we have hydraulic system s systems so the guy had to be strong to move these torpedoes. this is not live now, this is the match 14 21 feet long, 21 inches in diameter and weighs approximately 3500 pounds loaded. it has two speeds. it's a slow speed it will go 36 knots for a distance of four miles. on high speed settings she'll go approximately 50, 51 knots for a distance of two miles.

she is steam driven and she -- in this particular version it's a contact torpedo which means she has to hit the enemy to drive a pin into a pre-charge and then into the main charge. >> hundreds of men apply yearly for submarine training. they are draw unby the camaraderie of the service. they're screened first for physical fitness including 20/20 vision. then for intelligence and fast reaction time. the lives of 80 men may depend on the quick and proper closing of the hatch or valve. there's no room for a mistake. the thursday screening is by navy psychologists for social adaptability. the easy going study sailor fits best into the crowded conditions peculiar to submarine operations. >> well, usually the biggest thing that i hear from people is that the submarines couldn't last -- they couldn't work on

them because they're so tight. and true enough, the numbers will reflect that 97 out of 100 sailors can't do this job for one reason or another. some people can be here and -- in these tight quarters and it doesn't bother them. some people it bothers and most people it does. but it's more than just claustrophobia issues. there's a lot of technical details that at some point you have to learn all of the details of the boat from stem to stern and then you go before boards and they quiz you on do you know them this system? do you know this system? then you have a final signoff. okay. now we here in officer's country. what's considered officer's country. to my right is the pantry which is where the officers' food was served up on nice plates for the captain and his men and then they were served in here which is the ward room, which is where the captain and his men ate their meals they did a lot of war strategy and any kind of socializing the officers did

because they would keep to themselves and not particularly socialize with the crew. as navy tradition is. what also i point out is that hole in that wall between the pantry and the ward room, i like to ask people is that hole for? and of course a lot of people say it's for passing food from the pantry to the ward room which is not the case. what it was back in the '40s, television either hadn't been invented or it was extremely rare so the officers would have a reel to reel movie projector from the pantry side and in here in the ward room they would have a pull down movie screen and the officers would sit here and watch them old reel-to-reel type movies. here you have the captain's quarters. this is as good as it got. this is where the best accommodations was. you'll notice at the foot of the captain's bed he has indications of pretty much position of the ship, the direction, a gyroroe peter.

and i think we have an instrument missing. he could wake up and know which way the boat is going and how fast he's going. of course he would already know what it should be doing because he had left orders. we're still in the afterbattery compartment compartment. when i say compartment i mean from watertight door to watertight door. but this current part is called the crew's quarter. this is where the crews would sleep. and they often times would share the same bunk. is up with guy would get up, go to work another guy would get back in it and it would still be warm. one thing people don't realize water was a huge premium because the water that you did make was primarily used for the batteries. so you got to take a bath maybe every week or ten days. so the guy that just got out of that bunk stinks as bad as you. >> each man must acquire a working knowledge of each department of the submarine. the men study
