The warheads may have been intended for use in a Cuban programme to develop modernised self-propelled versions of the Soviet-era S-75 Dvina (SA-2 'Guideline') and S-125 Neva (SA-3 'Goa') surface-to-air missile systems.
The S-75 Dvina (SA-2 Guideline) Soviet-designed, high-altitude air defense system, built around a surface-to-air missile with command guidance.
