There were three Queen LSTs (Q007, Q009 and Q012). The Queen LSTs were WW2 American ships that following the war, rather than being scrapped, had been assigned to a Japanese government agency something similar to our Merchant Marine. They were given the designation SCAJAP LST Q007, etc. SCAJAP was the acronym for Shipping Control Administration – Japan.
