MV Empire MacCallum

MV Empire MacCallum was a grain ship converted to become a Merchant Aircraft Carrier or MAC ship.

MV Empire MacCallum was built at Lithgows shipyard, Glasgow, Scotland, under order from the Ministry of War Transport. As a MAC ship, only her air crew and the necessary maintenance staff were naval personnel and she was operated by Hain Steam Ship Co Ltd of St Ives. Amongst the aircraft that served on Empire MacCallum was Fairey Swordfish Mk II LS326 where it became part of 'K' flight. The aircraft had previously served on MV Rapana. As of November 2010, it is airworthy with the Royal Navy Historic Flight.

After the war, the ship was converted to a grain carrier, and eventually scrapped at Osaka in 1960.
