Commentary: It’s a bit weird that China would outfit the DF-5 with MIRVs. As the author points out the DF-5 is an older, liquid fueled missile. A liquid-fueled ICBM takes hours to prepare for flight, so it’s not the kind of a weapon to deter a no-notice attack. Why would China place more warheads from a limited stockpile on a vulnerable system?
It could be signaling by the PRC, that it can proceed with modernizing nuclear delivery systems if India and the U.S. do so.
