Chinese nuclear warheads.
DF-2 This is the warhead what's blueprint Chinese did give to Pakistanis.
DF-3A
DF-4
DF-5 the big 5MT weapon.
JL-1/DF-21 RV. Yield between 200-300kt.
DF-31 RV (as claimed by CCTV) yield could be up to 600kt.
Unfortunately DF-31A RV is hidden under payload shroud but I assume it's cone shaped like all other RV's.
