re: PLAN Type 071 LPD & its Landing Craft
Actually, it does not make that point at all. Remember, the PLAN only has one LCAC available for use. That's one in the entire PLAN. The second is still being tested.
That's not only the more plausible explanation for why there is only one in there, it is the only explanation available. They could not put more in if they wanted...so to practice amphibious assault, they had to use the other. Plain and simple.
Let's wait until they have 6-12 LCACs and see how they configure a typical loadout on the Type 071. Then we will no more about what their go-forward thinking and policy may be.
Believe me, there would be another story of PLAN from someone if there exists a picture showing 3-4 LCAC loaded in the belly of 071 class.
Floating tins are used to land on "beach" which are usually heavily defended or mined. Choppers and LCACs with MBT/SPG can land on inland which are not prepared by defendant. Attacking unprepared areas is attacking enemy's heart and unbalancing enemy's mind. It's called "Maneuver Warfare", not only "Amphibious Warfare."
Two thousand year ago, Sun Tze told us to attack in two ways, a normal way and a surprise way (正奇). Floating tins fights the normal way and maneuver arms such as choppers and LCAC fights the surprise way. It is US Navy practicing Sun Tze 's teaching, not Chinese PLA Navy.
