Cuban dictator Fidel Castro claims only one son, but he has at least seven children by three women. He preaches socialist equality but has 32 houses to call home and three luxury yachts.

Those are some of the disclosures about Castro that are now coming to us, and to the Central Intelligence Agency, from Soviet sources, including the KGB.The Soviets are sharing the information from the KGB because they are fed up with their heavily subsidized dilettante in Havana.

The one thing sure to anger the paranoid prima donna is an examination of his personal life, which is why our Soviet sources shared the details:

- Castro lives well in his 32 houses. Three of them are in Havana, and two are underground bunkers because Castro fears a nuclear attack by the United States.

- He has a bodyguard force of 9,700 men. Some 2,800 of them are stationed in Havana. If he is feeling especially paranoid, Castro can summon another 20,000 men from the Ministry of the Interior and the Army.

- He was spooked by past bizarre plots of the CIA to, among other things, make his beard fall out and poison him with toxic shellfish. So, when Castro indulges in his favorite sport of scuba diving, he has more than 100 frogmen check the waters for any foreign objects and protect him while he dives.

- Castro is known to be divorced from his first, and only acknowledged, wife who now lives in Spain. But the Soviet sources say he has at least five sons from a secret second marriage. They all have names that start with "A." (Castro's own middle name is Alejandro.) The Soviets know the sons well because they were schooled in the Soviet Union where Cuban security agents posed as their parents. Castro also has an illegitimate daughter named Alma Fernandez Revuelta, who is in her mid-30s.

- Castro's only acknowledged son, from his first marriage, is Fidelito, head of Cuba's nuclear agency. Fidelito married and then divorced a Soviet woman. He then married a Cuban but is about to drop her for a Spanish aristocrat.

- Castro's younger brother, Raul, has not been allowed the luxury of divorce that Fidel gave himself. At Fidel's whim, Raul stays married to Vilma Espin even though they despise each other. Raul, who heads the Cuban armed forces, has consoled himself with the bottle and an affair with the director of Cuban television (with whom he had a daughter) and more recently with a Bulgarian mistress.

While the details of Castro's personal life seem suitable for the tabloids, they serve as political leverage for the Soviets, who don't mind exposing Castro as a hypocrite.
