Cuba's helicopter fleet consists of 44 to 46 Mi-8/-17, plus 5 Mi-14 helicopter gun ships. The first version of the Mi-8 first flew in June 1961. The FAR operates the second generation of the Mi-8, version 17. The 17 is manned by a crew of two and can carry up to twenty four fully armed troops. It fuselage is 83'-1" in length with a height of 18'-2". The main rotor diameter is 69'-10". Cuba used the 17 as gunship platform configuration the helicopter to carry one 12.7mm machine gun housed in the nose section. Six outrigger pylons are fitted to carry the AT-2 Swatter 57mm rocket system. The Mi-14 Haze helicopter is basically a Mi-8 with a boat hull lower frame. It first took to the air in September 1969 and it was the backbone of Soviet Union combat helicopter fleet for many years after. The 14 is also manned by two crewmen. Its fuselage is measured at 83'-1" with a height of 22'-9". Tilt rotor diameter is 69'-10". The 14 have a similar weapon configuration as the Mi-8. FAR transport force consist of 8 An-2's, 1 An-24, 15 An-26's, 1 An-30, 2 An-32's, 4 Yak-40's and, 2 IL-76's, which are mainly used for civilian transportation. The air-to-air missile inventory is believed to consist of AA 2, 7, 8, 10, and 11. Their air defense capability surrounds 13 active SA-2 and SA-3 surface-to-air missile battery sites. The majority of them center in Havana. This force is incapable of defending Cuban national airspace against an enemy with high performance military aircrafts at its disposal. Because pilot training had been cut short and a lack of significant flying time by the Cuban pilots, Cuba would have to rely heavily on its network of surface-to-air missile systems to respond to any attacking force.
