On 7th December 1941, the Japanese attacked Pearl Harbour. On 8th December 1941, Congress approved President Franklin D. Roosevelt’s request for a declaration of war on Japan and within a few days, Germany and Italy declared war on the U.S. The U.S. became fully engaged in WWII..
Between 1939 and 1945, 3,500 Allied merchant ships, amounting to 14.5 million gross tons, were sunk.
The WWI USSB Emergency Fleet programme was generally deemed to have been a failure.However, shortages of steel, shipyards and skilled labour, combined with a need for more merchant ships, led to the Maritime Commission inviting 75 contractors to bid for the construction of a then undetermined number of reinforced concrete barges to relieve the shortage of tankers for transporting petroleum around the Atlantic seaboard.
In a comprehensive series of Blogs, we will share the outcomes of our extensive research into the Life & Times of 104 concrete vessels built in the US during World War II. Every ship will be covered, in what will become the most in depth encyclopedia of knowledge, about US WWII concrete ships, ever written.
These ships have many stories to tell. Many went to war, some never came back. One was almost became an island nation ! Today, sixteen of them are in plain sight, seven even float to this day.
We wrote a series of Blogs about the 'life & times' of these ships. You can visit our Concrete Ship Blog section or follow the links below
Concrete Ship Constructors of National City, CA, built more concrete vessels than any other constructor in the history of concrete ship building - 49 to be precise. It's an amazing story of success and in it we will cover four different designs of vessels used for four different purposes. The hull of one concrete barge was built in 6 days, 11 hours...a record that will surely never be beaten !
In preparation for the D-Day & other beach landings, BuDocks built a Landing Craft Tank (LCT in concrete. It was a prototype, it worked fine but was never put into full production.
Our Blog explains all about this unique one-off concrete vessel
Drawing on WWI experience with concrete barges, BuDocks experimentally built a couple of concrete barges which were for docks and harbour use. They were pre-stressed concrete
Our Blog tells you what we found out about them.
A shortage of floating dry-docks to be deployed for repairing ships engaged in the war led BuDocks to build 13, 2,800 tons Auxiliary Repair Docks (Concrete) - the ARDCs.
In a series of Blogs, we will tell you all about them
