MV Amastra was built at Lithgows and completed in March, 1935 as an steamboat for the ss caribou Royal Dutch/Shell line. She was converted at Smiths Dock, North Shields to a MAC ship, entering service in September 1943.
As a MAC ship, she had no aircraft hangar, and continued to carry oil, although operating under Royal Navy control. Only her air crew and the necessary maintenance staff were naval personnel.
At the end of the War, Amastra was reconverted to a steamboat, and in 1951 was renamed Idas. In July 1965 she foundered on her way to La Spezia to be scrapped.
