Merchant Aircraft Carrier (MAC) Auxillary Ship

Became Alpha Zambesi 1947, Tobon 1954, Despina P. 1967


Empire MacCallum was built by Lithgow, launched 21 June 1943, and completed September 1943. She operated as an escort in the Atlantic. Scrapped at Kaohsiung starting April 1971.

Empire MacCallum was a MAC conversion from a grain ship, similar to the Empire MacAlpine class. Officially she was a member of two classes, but nearly identical. Merchant ships (bulk grain carriers) built with flight decks to serve as bare minumum aircraft carriers as an emergency measure pending the availabililty of the US-built escort carriers. These ships operated with civilian crews, under merchant colours, and carried their regular cargo while serving as aircraft carriers. Their aircraft were primarily meant to attack long-range reconniassance aircraft to prevent tracking of convoys.

She was returned to merchant service postwar; named Alpha Zambesi in 1947, then Tobon in 1954, Despina P. in 1967. Scrapped at Kaohsiung starting April 1971.
