re: PLAN Type 071 LPD & its Landing Craft
Without a practical load on the LCAC and judge by the ramp alone (structures on both sides seems to be close in size with the US LCAC), the Chinese one is about 1.5 HMMWV shorter by width. To go by the logical assumption that the 3320 LCAC and 071 class LPD is part of the whole package to begin with, then it'd safe to say that unless PLA Navy is planning for bigger LPD or even LPH, they're stuck with this LCAC.
It's a logical approach, should 3320 boat is indeed a proof-of-concept and lead-in unit for them, and China is still years away to produce their own gas turbine engine that can propel a LCAC in the same category as the US one.
Still, it's an achievement nonetheless, for only a handful of nations today that can build LCAC of this weight class.
