I wonder if we will have the same go-around regarding the vulnerability of silo basing that we saw during development of the otherwise excellent (but very pricey) LGM-118A. Just my 2 cents but the money would be better spent on the Columbia class project, and Northrop is already getting more than enough moolah from the Air Force for the B-21, it’s time to give up the silo launched missiles and move on.
