I think the torpedo on display in Batfish's FTR is a Mk. 45 - minus the nuke . :)

School of the boat for 26 Aug 08 - checking Lance's answer
« Reply #16 on: September 06, 2008, 12:19:40 PM »
OK finally got time to check Lance's answer to this question: What is the total amount of variable ballast in pounds that a Balao submarine has at its disposal.  (i.e., pump out or in to surface or in emergency)?

Lance was correct 231,640 lbs (115.82 tons of sea water)

Forward Trim - 24.31 Tons of sea water
Fwr WRT = 4.94 tons
Aux Ballast 1 = 30.77 tons
Aux Ballast 2 = 30.77 tons
After Trim = 19.97 tons
Aft WRT = 5.06 tons
total = 115.82 tons x 2,000 lbs = 231,640 lbs

231,640 lbs / 8.56 = 494,350.47 gallons of sea water if anyone cares
1 gal of sea water weighs 8.56 lbs due to sea water being about 2.5% heavier than fresh water (approximately) :)

From what I've learned so far, I would HATE to be the man in charge of maintaining the records of weight on the boat and trying to figure out trim.

Lance,
It wasn't that bad to maintain the records as to what was onboard the only time that I saw anyone have any REAL problems with getting a good trim dive was when the boat was fresh out of the shipyard or it had been a while since there were a full load of weapons onboard instead of one or two for self defense and then it was a fun dive especially if they calculated light (better to be light then heavy IMHO) and the Diving Officer of the Watch had to fight to get her under water or on the flip side fight to get her back to ordered depth while pumping/blowing all kinds of variable ballast out and having to have a higher bell ordered until a good trim dive was achieved.

I don't know - we had a cook stricker "Fat Eddy" and eveytime he stayed ashore for somethinng - our youngest diving officer had a hell of time to trim the boat - see he never paid attention to the fact that "Fat Eddy" was still on the base.
