Nice episode with some relevant tidbits. Including: JL-3 is the interim JL-2 successor on 094 (supposedly not named 2A/B because they didn't like the name) which you shouldn't have "overly high expectations" for, JL-4 is for 096. And that western reports on the underground great wall are overblown (particularly the 5000km figure). Yankee also mentioned offhand KJ-500 count exceeds E-2D already. And lots of other stuff.
I am just wondering if they mentioned anything from their perspective about next-gen ICBM?
I am still skeptical of the designation of "JL-3" as it is merely supposed to be an extended-range version of JL-2 and given the precedence of DF-31A to DF-31, no reason to name it as "JL-3." As for SLBM for 096, it is another beast for decades to come, at least from public information.
Underground Great Wall is never real from the very beginning. The idea is to make first strike uneconomical for the adversary and ideally one needs to build separate shelters around the country instead of a tunnel 5000km long.
