The Italian auxiliary cruiser Ramb III was built at Genoa by Ansaldo in 1938. Ramb III was the third of four sister ships all built to the same design. The other ships were the Ramb I, the Ramb II, and the Ramb IV. The four ships were built for the Royal Banana Monopoly Business (Regia Azienda Monopolio Banane). These ships were originally built to be "banana boats", built for transporting refrigerated bananas to Europe from Somaliland and Eritrea in Italian East Africa.
