Very large assembly platforms are being ordered by Bohai yard, mostly seem to be ~14m in diameter.
this is second time 14+m assembly platform tender info appeared.. interesting

first time in March this year. see this down below
Bohai Shipyard is looking for an assembly platform for a circular/rim part up to 14 meters

It wasn't particularly surprising given JL-3 should be slightly larger in term of diameter. If 14 meters is for beam, then 096 should be slightly larger than 955 and Ohio as well.

sorry.. didn't check the date.

@ACuriousPLAFan @Tomboy so can we guess, first 096 boat construction started or start soon.

Hopefully so.



On the other hand, provided the listed dimensions of the tender document do match with the eventual real thing - With a 14-meter diameter hull, I would absolutely LOVE to have a SSGN variant that is based on the hull of the 096 SSBN.

With 16x missile tubes for the JL-4 SL-ICBMs (of hopefully 2.4-meter diameter), this could enable the dual-packing of <1.2-meter diameter strike missiles (i.e. 32x total) for anti-ship/land-attack missions at medium and/or intermediate ranges, in addition to taking advantage of the larger submarine hull diameter for longer missiles.

Needless to say, having such capability is certainly going to offer serious punches for the PLAN across the wider IndoPac... Alongside sustaining a longer production run for the 096 (family).

Not exactly news per se, from SOYO on Weibo.

Bad News: With a 14-meter outer diameter hull, a large turtleback (on the 096 SSBN) is inevitable. And even if the outer diameter is made to be slightly smaller, the degree of bulging of the turtleback wouldn't be that much smaller than the turtleback of the 094/A/B SSBN
Good News: The SL-ICBM carried (by the 096 SSBN) would be a vertiable (名副其实) intercontinental-ranged missile

So... Does that mean the JL-4 will become the largest SL-ICBM to enter sevice in the whole world in the coming years?

My gut feeling says it would not matter much unless it like the earlier Deltas. SSBNs go slow. Their deployments are famously "2-5 knots to nowhere". They are very well streamlined with smooth transitions but the Ohios and Vanguards do have humps.

Implying that the JL-3 is not yet intercontinental-ranged?
Nope. It just implies the requirements for the JL-4 are substantially higher. I was once discussing this with @tphuang. They will go for a missile that can throw a substantial payload to most of the CONUS from the middle of SCS. It is something you either have or you don't. Such a big missile probably implies multi-MaRV/HGV applications which make sense considering the emergent ABM technologies. With a lighter payload, FOBS and very high speed depressed trajectory shots would become viable. The latter is especially valuable if they ever pivot their doctrine to counterforce strikes. And even if they never do that, forcing enemy countries to think about "what if" is beneficial on its own.

Given the size constrains of the 094/A/B SSBNs, I'd say that the JL-3 does have intercontinental-range capability, though likely facing similar payload capacity downsides as the JL-2.

If I'm not mistaken, the Guancha Trios (indirectly) hinted that the JL-3 holds the record for the world's longest-ranged submarine-launched solid-fueled missile, as due to geographical constrains, China is one of the few countries (or more like the only country) that puts the heaviest emphasis on the strike ranges of their SL-ICBMs.

With this in mind, it is expected that the JL-4 should have the same degree of intercontinental reach as the JL-3, while also having significant payload capacity upgrades over all preceding Chinese SL-ICBMs.

At least according to Wikipedia, the R-39 SBLMs carried on the Pr. 941 Typhoon-class submarines were 16m long, 2.4m in diameter and weighed 84 tonnes. The unprecedented size of the submarine was in part a function of the size of the missiles, plus Russian design standards for reserve buoyancy and other passive survivability measures.

Russian sources give 90-96 tons within same dimensions, perhaps for later R-36U from 1988.
