With the U.S. breaking relations (in 1961) and the imposition of the U.S. embargo on Cuba (in 1962), Cubana was forced to cancel all its U.S. services and turned to the Soviet Union to obtain new aircraft. The first Soviet-built aircraft were delivered in the early 1960s (Ilyushin Il-14 and Il-18), and were used in Cubana's domestic routes. Cubana thus became the first airline in the Americas at that time to operate Soviet-built aircraft. During the decade, the An-12 and the An-24s were also added to the fleet. Cubana's cooperation made it possible for Aeroflot to establish 18-hour non-stop scheduled services between Moscow and Havana in 1963, using Tupolev Tu-114 turboprop airliners, which were the longest non-stop flights in the world at that time. Cooperation with the East German airline Interflug also made it possible for this carrier to establish its first scheduled transatlantic services, linking East Berlin with Havana.
