Cubana placed orders for four long-range Bristol Britannia (Model 318) and four Vickers Super Viscount (VV-818) aircraft, all turboprops, for its international services (which included Madrid, New York, Mexico City, Miami, Montego Bay, Nassau, Port-au-Prince), and for some of its domestic routes (Camagüey, Santiago de Cuba, Varadero).

The last Viking amphibians were built during 1923, but the name was re-used for the twin-engine VC.1 Viking airliner some 22 years later, which saw service as the Valetta with the RAF and other air arms. Some Viking amphibians were built by Canadian Vickers Limited, a subsidiary company in Montreal with no previous aircraft manufacturing experience. Their involvement with the Viking led to a future line of indigenous flying boats beginning with the Canadian Vickers Vedette. No Vikings survive today
