SUBJECT

  • blockade Military Aid to the Castro Regime

The Soviet bloc has supplied large quantities of arms and military equipment to Cuba since major shipments began last September. The value of these arms is estimated at between $50 and $100 million. Thus far bloc military deliveries have consisted almost entirely of land armaments, including medium and heavy tanks, self-propelled assault guns, field and antiaircraft artillery, large numbers of military vehicles, and ample quantities of infantry weapons and ammunition.

Although there are occasional rumors, apparently emanating from Cuban refugees, that naval equipment has been supplied, these rumors cannot be confirmed.

Bloc aircraft delivered to Cuba include helicopters and light piston-engine Czech basic trainers. There are some unconfirmed reports of crates of the size which would hold MIG fighters, but there is no corroborating [Page 390] evidence that these aircraft have been delivered to Cuba. It is highly unlikely that MIGs are presently operational with the Cuban Air Force. Cuban pilots are training in the bloc.

Bloc Military Negotiations With Cuba

The Sino-Soviet bloc maintained a cautious attitude toward the Cuban regime for more than a year after Castroʼs takeover in January 1959. Although intermittent Cuban military contacts were made with the bloc during 1959 and early 1960, these apparently did not result in firm military aid commitments from the bloc until about May 1960. In this period sizable quantities of small arms were procured in Western Europe, primarily in Belgium.

Soviet First Deputy Premier Mikoyanʼs visit to Cuba in February 1960 signaled the beginning of a series of trade and aid agreements between Cuba and all countries of the Sino-Soviet bloc. As political and economic ties were established, it became clear that Moscow intended to back up its propaganda support for Cuba with a major campaign of material assistance. Following the collapse of the summit and the cancellation of President Eisenhowerʼs trip to the USSR, however, the bloc undertook active military negotiations with the Cuban government which culminated in arms agreements with both the USSR and Czechoslovakia.

By the end of July 1960 Czech small arms and ammunition were in Cuba. Shortly thereafter, the first large group of Cuban military personnel was sent to Czechoslovakia to receive military training.

In September the first large bloc arms delivery was made. Since then military equipment has been regularly supplied to Cuba. In addition, large numbers of military usable vehicles and military-related items have been delivered.

Bloc Military Technicians

A large number of Czech and Soviet technicians currently are working in military capacities for the Cuban government. These technicians are assisting the Cubans in assembling equipment and installing such weapons as antiaircraft batteries. They also are employed as instructors in military courses and as advisers to individual military units. Bloc instructors probably have been participating in flight training being conducted in Cuba on Czech piston trainers.
