This is the Thomas Lawson, a seven masted schooner they built in 1902.
But it's the U.S. Navy ships I want to focus on.
They built the first USS Lexington (CV2) in 1927 and when she was sunk at the Battle of the Coral Sea and they built the second USS Lexington (CV16) in 1943, along with the carriers USS Wasp, USS Bunker Hill, and USS Hancock.
The battleships USS New Jersey (BB-16), USS Rhode Island (BB-17), USS Vermont (BB-20), USS North Dakota (BB-29), USS Nevada (BB-36), and the USS Massachusetts (BB-59).
Here's the USS Massachusetts. Another ship with a battle history worthy of a post.
Add to that 32 Cruisers, 63 Destroyers, and 49 Subs.
A lot of that was WWII production. There were 32,000 people working in the shipyard in 1943. In 1950, the number of workers was around 3,200. There was production throughout the life of the yard, but in the end the last ship was a cargo vessel, the USNS SGT William R. Button.
The docks and buildings are there and have been reasonably maintained. The tools, the equipment, and most importantly, the people are gone. Maybe we'll never need to build ships like these again. But if we do, at least at Quincy, we'll be starting from scratch. Here's what's left.
