Some brewed thoughts on the 09VI SSBN, within the context of whatever information and rumors that have percolated through the internet in the past few years:
On the construction timeline
My guesstimate is that the first boat will be launched no earlier than late 2026 but most likely in 2027 (perhaps 2028 if there are delays). This is based on a few clues that we've gotten in the near past:
- The first tender for an assembly platform that supports a 14-meter-diameter hull (and for the demolition of older assembly platforms) was published in January 2023.
- A second tender was announced in January 2026; I wonder if this is for a follow-on hull or an indication that more halls of the facility are now being dedicated to 09VI construction.
- There are reports that components for a "large pressure hull" were spotted in November 2023 (). Does anyone have satellite images of these supposed components?
- The time from initial assembly to launch is generally about 3-4 years. This is actually consistent with both US and Chinese sub development in the recent past, with the exception of a few cases.
- The subsystem tenders for the 09V submarine date back to as recent as the end of 2022. If we assume that the 09VI follows a similar time frame in terms of construction and assembly, a 2027 launch wouldn't be unreasonable.
- Historically-speaking, Chinese SSBNs have followed SSNs closely in terms of construction and commission dates. AFAIK, the first 09IV was launched not more than two years after the first 09III did so. Obviously, the 09VI would be larger and more complex than the 09V, but Chinese R&D and manufacturing have improved substantially as well.
- For what it's worth, US intelligence has estimated that the 09VI would enter construction in the mid 2020s. A steel-cutting date in late 2023 would be in line with this assessment.
On the prospects of a 09VI SSGN variant
I see a lot of comparisons being made between a notional 09VI SSGN version and the Ohio-class SSGN. It is worth noting that the Ohio-class SSGNS
were not actually purposely-built. They are the result of the USN choosing to reduce its SSBN fleet down to 14 boats after 18 have already been built, partly due to treaties with Russia. In fact, the four "extra" boats were initially slated to be retired prior to being reactivated for SSGN conversion. AFAIK, these Ohio SSGNs are the only SSGNs that are built from SSBN hulls. Even the Russians have seemingly delegated SSGN tasks to their Yasen SSNs so as to combine the SSN/SSGN roles into one hull.
If China really wanted, she could commission a "stretched" variant of the 09V or even convert the old 09IVs into SSGNs, but given the emphasis of the PLAN on anti-shipping rather than expeditionary land-attack duties, these are unlikely prospects. For the time being, given the doctrine of the PLAN and the naval force structure that supports it, 24 VLS cells on the 09IIIB and 09V would be more than sufficient.
