Balistic Missile Defences....
I have been looking at the USAF's Safeguard system of the 1970's
In its test phase both the Spartan and the Sprint missiles were making good intercepts in the test program. The system was proving effective enough in tests for the US to start building the systems to defend mainland United States. One of the 'missile fields' were completed but under the terms of the SALT II talks the base was closed two or three days after it opened.
The Soviets were concerned enough about the system that they included its deployment in the SALT talks.
I have set up computer simulations of all the planned "fields" and well those simulations have shown the system could have stopped about 70 to 80 percent of the warheads that were coming in, though the Spartan and Sprint missiles also chased down decoys.
Still considering as many warheads coming in to the US, from Russia, that 30 percent could still be devastating.
I wonder if Safeguard would have really worked in real life...? I wonder if the system was worth the money the US spent on it, and then just stopped using it? What do you all think?
