JL-2 is based on 7000-7500km range DF-31.
It's estimated that newer DF-31A is slightly longer than DF-31.
Then how do you explain that Trident 1, weight 32 tons can fly 7500 KM and deliver 8 MIRV, while the 42 tons JL-2 can not fly 11,000 KM and deliver 3 MIRV ?
JL-2, at 42 tons can only deliver 3 MIRV to a range of 7400 KM ?
Also the Bulava, at just 37 tons can deliver 6 MIRV to a range of 9000 KM !!
