List of concrete liberty ships built worldwide

Are you daft? They were coming off the slipways every 3 to 4 days in
America. Had a drop in diesel Engine..and went asailing for the British
Isles.


They were of welded steel construction and typically had triple
expansion steam engines.

Who is the daft one here ?

PS the original design came from the shipyards of
NE England and the first ships built were called the Ocean Class.
When the United States Maritime Commission adopted the design
they substituted welding for the original rivetted construction
and replaced the coal fired boilers with oil burners.
