This ship might not be for peacefully exporting electric cars. China is making unmistakable preparations to invade Taiwan in the near future and RORO carrier vessels have clear military applications in such a scenario.
Consider this analysis of the invasion barges they’re preparing: https://m.youtube.com/watch?v=Klkpk_hO4FQ
China still has an amphib fleet, and there are reasons to use amphibs for at least the initial forced entry operation, but once you have a beachhead the dual use ROROs are a good way to sustain and reinforce the landing force without needing to capture or build a port facility.
And it’s not like the amphibs are only useful for Taiwan; there are plenty of disputed islands in the South China Sea worth fighting over.
Specialized pieces of amphib equipment for initial landing, but bulk of sealift is going to be done via commercial ships / RO/ROs. Likely down to 100,000s of fishing boats / commercial vessels to distribute survivability for a reverse dunkirk. Point is PLAN never had intention to build out enough gray hulls to ferry 100,000s men + equipment, so analysts/arguments fixating on PRC _military_ sealift readiness needs to recalibrate on what % of sealift work will actually be done by military procured hulls. My guess is... very minor %, and a shockingly many of commercial ships will get drafted / voluntold to assist with sealift.
SCS islands are too small to need amphib. Like even largest Taiping island is basically just a 1km long airstrip. LHD + paratroopers is enough. Maybe for Ryukyus if things get really spicy.
You probably wouldn’t use a ship like this in an initial landing, but once you’d secured a beachhead you could easily use it to deliver reinforcements and supplies. A major part of the value of a RORO ship is that you need little to no port infrastructure to unload it. Once you’ve secured a beachhead and built some minimal infrastructure on it you could land tanks and other armored vehicles, or you could also land trucks filled with fuel, ammunition, supplies, infantry, and so forth. This is, in practice, most of the work that LST’s did as well.
And it’s very common to requisition merchant RORO ships for amphibious operations. The British did so during the Falklands War (https://en.m.wikipedia.org/wiki/SS_Atlantic_Conveyor).
That is a very good observation and a really interesting video.
Why not both like Merchant Marines.
Dual use sealift is just common sense. Too many years of stupid western analysis that PRC would waste $$$ to build dedicated TW amphib fleet, and point the absence of one as PRC not ready to invade TW. Reality is every $$$ PLAN spends on sealift is one not spent on weapons shooting back at US+co.
PRC RO/ROs (and a lot of other commercial shipping) are indeed build to military standards for TW scenario. Used for shipping cars like they're suppose to during peacetime to let that capex work, and armor vehicles during war.
Comparable RO/ROs have been actively involved in invasion TW training/exercises. PRC RO/RO numbers a couple years ago was enough to land 7 full PLA group armies (300k + equipment) on TW in about 10 days, or every US Army Brigade Combat team in 5 days. They'll probably have enough RO/RO sealift to cut that down to 2-3 days in a few more years.
