Regardless, it’s time to upgrade our ICBMs. The SLBM’s are still good, but the ground based leg is awful.
I’d also work out a treaty for some testing to make sure these old things still work.
We launch four to six Minuteman III ICBMs every year for the Follow On Test & Evaluation (FOT&E, or "Foot Shot" program.
These missiles are randomly selected from the operational Wings and shipped to Vandenberg AFB, CA. The missile is installed by the original Wing maintenance crews and then launched by the original Wing operations crews. The only thing not original on the bird are the nukes, which are replaced with either inert or telemetered re-entry vehicles.
