Manitowoc Submarines

Manitowoc was a ship building company that transitioned to crane building. During WWII, they were still building boats, and they produced 28 submarines. These were some of the boats that caused the bridges on the Chicago Sanitary & Ship Canal to be made movable because the St. Lawrence Seaway did not open until 1959.

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.

1. "Speed Cranes" lifting Section H of the Peto (SS-265), into place 21 June 1941. The ship alongside this berth is the passenger boat SS Theodore Roosevelt which was laid up at the yard all during WWII. It was used to hide goings-on from possible prying eyes. Note: The "Speed Cranes" were designed and built by the shipyard specifically to handle the Submarine Sections. At the time they were about the biggest capacity crawler cranes built. The design later became the standard 3900 model produced by Manitowoc Co. and was one of their most popular models until superseded by heavier models.
David Waller Them were big cranes in their day
Mike Collins There was 28 submarines built in Manitowoc. The Museum there has history on them. The Cobia is at the museum, can take tour. The Cobia is the same class as the Manitowoc Subs, but built in Ohio, I believe. None of the 28 survived. My Dad served on the Menhaden SS-377. One of the 28.
Bob LeClair Four of the boats were lost to WWII action. The rest made it through the war. Some were modified and served until about 1960, others were sold off to other countries like Brazil and Turkey.
Mike Larson That's an interesting photo. A lot of the ones in the company archives when I worked there had the face of the submarine section grayed over to hide detail so enemies couldn't see the details of the sub's construction. Photos like this were few.

Mike Collins I was just running a 3900w at the mouth of Chicago river at the lake. This memorial was just outside the job on the river near Navy Pier in Chicago. The other side lists each submarine built.
Rick Webber It's on the riverwalk on the south side of the river. Worth checking out. And the Tiki Bar is next door so on a nice day this spring you can relax and have a drink and watch the boats.

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.

Also: Submarines on the Chicago Sanitary Canal

Manitowoc’s 28 Freshwater Submarines
The Manitowoc-built submarines have become known as Freshwater Submarines since we were the only freshwater port to build subs. Of the 28 submarines built here, 25 were built in time to see action during the war. Together they sank 132 Japanese ships. Four Manitowoc submarines were lost at sea, USS Robalo, USS Golet, USS Kete, and USS Lagarto. The four boats and their brave crews are now on Eternal Patrol.

The USS Silversides Submarine Museum in Muskegon, MI, has a video of a tour of the insides of a Gato-Class submarine.
