What does the US put in Turkey and Italy, and is the Cuban Missile Crisis avoided?
good question
Jupiter was MRBM with range of 2400–2700 km
that match the Polaris SLBM who were proposed as land MRBM
But Polaris would operational in 1961, while Jupiter came in 1958
alternative the Thor MRBM operational in 1958 in UK with better range 2800 km
lets look on Warhead side
Jupiter had W39 (3,47MT) and W49 (1,44MT)
Polaris had W47 (1,2 MT to 600kT)
Thor had W49 (1,44MT)
However the Jupiter play crucial role during 1958 to 1963
It could "deliver" fast a W39 Warhead on important targets under SIOP
This were soviet Air command, certain air-defence sites and even Moscow
Those could Jupiter hit fast from Italy and Turkey
open gaps for incoming SAC Bombers and Navy Bombers.
Without the Jupiter SAC needed more Thor to hit there "destination" means far more Thor in UK, Italy and Turkey.
what would made the Soviet more nervous as already.
Ironic it was Soviet Sputnik that Saved Jupiter from cancellation.
Original Jupiter program had to end as NAVY pullt out the joined program official in January 1957
while ARMY were fighting with USAF who build and use Missile with Nukes on it
secretary of defence limits the range of ARMY missile unter 370 km range
so Jupiter wanted to cancel the program, but new ARPA explained it good system ready for production.
then soviet launch R-7 with small satellite. Jupiter was rush into production.
