It was a 927-foot long dry-dock with a beam of 256 feet and which was built in the United States in 10 separate sections. The construction took one year from 1943 and 1944. The chief officer of this dry-dock was Joseph Rochefort at the beginning, but he was transferred later to another ship. It was commissioned on August 14, 1943 and conducted operations for 2 years until it was decommissioned on February 28, 1946. The same year, after the war, it was redesignated as AFDB-2. Some of the sections were redesignated subsequently as follows: section F to IX-524, section D to IX-522 and section H to IX-535. Other sections like B, C or J were disposed of in support of fleet training exercise in 1990. The same year, sections A and G were sold for scrapping and sections E and I were sold for reuse or conversion.
