5. Editorial Note
A Department of Defense study, “Evaluation of Possible Military Courses of Action in Cuba,” January 16, 1961, reported that as many as 100 Cuban pilots were undergoing flight training in Czechoslovakia and that the USSR had delivered to Cuba in the past 5 months at least 20,000 tons of arms and equipment. So far the U.S. had “no evidence of the Soviets providing Cuba with sophisticated weapons such as missiles or nuclear devices, or MIG jet fighter aircraft.” For text of the study, see Foreign Relations, 1961–1963, volume X, pages 36–40.
