Manitowoc Shipbuilding Company

Launching of USS Robalo 9 May 1943, at Manitowoc Shipbuilding Co., Manitowoc, WI.

Manitowoc Shipbuilding Company, located in Manitowoc, Wisconsin, was a major shipbuilder for the Great Lakes. It was founded in 1902, and made mainly steel ferries and ore haulers. During World War II, it built submarines, tank landing craft (LCTs), and self-propelled fuel barges called "YOs". Employment peaked during the military years at 7000. The shipyard closed in 1968, though the company lives on as the modern day Manitowoc Company.

Submarine Building Program

Shipyard President Charles C. West contacted the Bureau of Construction and Repair in 1939 to propose building destroyers at Manitowoc and transporting them through the Chicago River, Chicago Sanitary and Ship Canal, Illinois River, and Mississippi River in a floating drydock towed by the tugboat Minnesota. After evaluating the plan and surveying the shipyard, the Navy suggested building submarines instead. A contract for ten submarines was awarded on 9 September 1940. The Navy paid for lift machinery on Chicago's Western Avenue railroad bridge to clear a submarine. The 15-foot draft submarines entered the floating drydock on the Illinois River to get through the 9-foot-deep Chain of Rocks Channel near the confluence of the Mississippi and Missouri Rivers. Submarines left the drydock at New Orleans and reinstalled periscope shears, periscopes, and RADAR masts which had been removed to clear bridges over the river.^[1]

Manitowoc had never built a submarine before, but the first was completed 228 days before the contract delivery date. Contracts were awarded for additional submarines, and the last submarine was completed by 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.^[1]

List of Fleet Submarines Built by Manitowoc

One of the 28 Manitowoc submarines produced, used in the Pacific Theater, from 2 April 1943 to the end of the war, on 15 August 1945. Two lookouts are posted next to the periscope shears. Her bow planes are rigged in, main gun visible on deck aft. Notice the limber holes and saddle ballast tanks.
