Minuteman III has a throw weight of 1,150 kg and a weight of 35,400 kg. a 31:1 ratio.
Comparison with similar throw weight RS-24 (3,260 kg) which has a weight of 49,600 kg, which is a 15:1 ratio. Some of that is environmental protection (insulation, humidity seal) and extra reinforcement because it's truck-mobile and riding all over Siberia.
Comparison with silo-based missiles that does not need extra reinforcement or massive insulation gives us RS-28 which has a throw weight of 10,000 kg and a weight of 100,000 kg, a 10:1 ratio.
Comparison to other missiles America has in service gives us Trident II, with a throw weight of 4,320 kg and a total weight of 58,500 kg, for a ratio of 13:1… probably due to naval environmental protection. It would be 10:1 or better without it.
I'm just using general weight as a comparison analog here, obviously assuming that if something has a better throw weight ratio, it must mean the fuels are better, electronics in the missile is lighter and engineering is superior. It's not a wild assumption, and good enough for a polynesian coconut carving website.
tl;dr the appropriate thing to do is to make a land version of trident and put it everywhere, because it's the only missile in the west that's actually competitive.
Call me when they do that, "upgrading" the geriatric minuteman isn't a solution.
