Concrete Liberty Ships

At the end of World War 1 and into World War 2 The United States relied heavily on Liberty Ships. Freighters which kept the products from the foundries and factories moving across the seas to support our allies. 

What many people don't know is that they were not all built the same. The normal image that pops into peoples minds when you say Liberty ship construction is steel ships sitting in the ways. What many people don't know is that there was another type of ship built, the "concrete ships". 

The thing is, the day of the Liberty ship is long over, and most of the steel ships went for scrap, But there is still a large collection of the Concrete Fleet surviving today. 

As a matter of fact, there is even a rather large group of them still at work today, forming a Breakwater.

One Breakwater is the Kiptopeke breakwater, still protecting Chesepeake Bay.

Another Concrete Ship Breakwater is on the Powell River in British Columbia.
