This new design was the basis for the Liberty ship.

As of 2009, this Liberty ship is well on its way to being reduced to dust.

Liberty ships were typically assembled in a little over two weeks.

A number of other Liberty ships suffered similar problems, with three sinking.

More than 2,400 Liberty ships survived the war, only 196 having been lost in combat.

Liberty Ships were built to support the war effort.

San Francisco was the home of the liberty ships.

Liberty ships continue to serve in a "less than whole" function many decades after their launching.

At times, shipyards spat out a new Liberty ship every four days.

The design was an enhancement of the Liberty ship, which had been successfully produced in extraordinary numbers.
