I knew Manitowoc got into the crane building business because no one was building a crane big enough to meet their needs. Judging from some comments, these submarine modules were the lifts that required a bigger crane.

David Guarino That is a small area to spend a lot of time underwater. I remember seeing the captain's 'cabin' on a WW2 submarine. It was about the size of a small closet. Interesting how they constructed them in sections like that. I think Electric Boat/GD still does it that way.
Hans van Vliet When Manitowoc starts building submarines in this way they where ahead of that time. They delivered their first submarine 228 days ahead of schedule. Finally they build 28 subs, and the last one delivered on the date scheduled for the 10th submarine of the original contract. Total production of 28 submarines was completed for $5,190,681 less than the contract price.

Here's a cool thing I learned several years ago when visiting Manitowoc, Wi, during WW2, submarines were manufactured there & put on barges & floated down to the Illinois river & then to the Mississippi River to New Orleans for them to put the final touches on the subs. They said at the museum that they couldn't float them down the river, is because the draft were to deep for the subs. I would like to see more pics of subs on barges going down the Mississippi, if any of you guys have any.
