Ground Based Interceptor (GBI)

[Scott Kenny]

Trident motors use class 1.1 propellants and are made with a mixture of HMX, nitroglycerin and nitrocellulose to go along with the AP and aluminum. The one mile safety distance was only for viewing the 3rd stages. 1st and 2nd stages had a significantly longer safe viewing distance.

Time from seeing the detonation to arrival of sound/shockwave from a trio of C4 second stages and a D5 first stage was still right at 5sec.

I'm sure the US has some about-to-expire Tridents and Minutemen available to use... Though I think the MM are kinda hard on their silo with the hot launch.

The Vandenberg silos were reused over and over for test launches
