Alright folks, this is one of my favorite subjects and I am sure that my fellow TM's are glad that we have FINALLY gotten to this block of school of the boat and this one is going to be a bit longer then the rest (and not just because I am a TM knuppel2) it is the IMHO the sole purpose for why we get underway and go underwater for LOOOONG periods of time (or at least for us nuke TM's) 

SO with that being said lets start with the basic description of the tubes to include the dimensions of them and associated systems involved with the torpedo tubes Wink

Alrighty, the basics:  6 tubes forward, 4 aft.  They are bronze 3 piece castings 21.125" inside diameter.  The bow tubes are 252" the aft tubes are 276" long.  They need flood and drain water from the WRT tanks, 3000 PSI air for torpedo charging and impulse and 200 PSI service air to make all of the swiss watch stuff work and to blow the tubes empty.  Some of the main components are the tripping latch, poppet valve, stop cam, interlocks and torpedo setting mechanisms.  I hope this in some way makes up for asking a vet on the Torsk where the slide valve was when I toured her sometime in the 1980s.  Terry

Terry it sounds like you may have been a TM also?  Don't feel bad about asking a Torsk vet about the slide valve because that was one of the first things that I looked for when I got on the Torsk 5 years ago and found out rather quickly that the basics are the same but that little jewel isn't on a fleet boat Wink

It gets real dark inside a tube!  But part of the maintenance checks had to be done from inside. crazy2

This torpedo tube stuff is putting me to sleep.  Someone please wake me up when we get to the good stuff, like Radio, ECM, or electrical distribution.  Wink

Did I just hear a FAINT PING out of the Radio Shack from Torsk?Huh?? the CHIEF must have wired something wrong because I know that that couldn't have been a REAL ping coming from Torsk because I do remember that a SUBMARINES PING IS LOUDER THEN THAT....  BTW Chief, I know that you have been working REAL hard on YOUR part of the school of the boat that will be coming NEXT Wink

While Darrin is working on our torpedo tubes, which are the best part of a fleet-type submarine.  Marvels, such wonderful pieces of equipment - so much better than all that radio gear. I thought you would like to read about the development of why we go to sea - the torpedo.

Here are five parts of an article on the development of torpedos.

By the way speaking of pinging and torpedo tubes.....Show of hands, how many people dove a tube and of those how many were initiated in some way.  You know how those TMs love to prank.    TK

I would have loved to been there when the duty TM asked her to clean his tube for him 2funny   but she did it and I missed it, hate when that happens... although did get a female porn star tube loaded on Hono once, lotta fun that night!

Yes TM's do get initated when diving the tubes for the first few times they dive the tubes, every thing from having the breech door shut to actuating the wire cutter and even diving the tube with nothing on while up north during the winter..

I was lucky I guess, never had a set of stern tubes until I started working on Torsk... heard rumors about the guys aft couldn't hit the broad side of a barn though with the "shorter" tubes forward 2funny   

Also from the Forward Room,
