re: PLAN Type 071 LPD & its Landing Craft
Come to think of it, LDPs aren't really a bad idea for Pakistan Navy. It would certainly boost Pakistan Navy's capability, in so far as Amphibious Assault is concerned. Also, it should be noted that Pakistan Navy does have the Griffin Hover Craft in its inventory. Any craft in a larger class would also mean the expansion of Pakistan Navy.
I personally believe that it is important for Pakistan Navy to increase its fleet and capabilities, vis-a-vis the current geo-political climate in the Persian Gulf and its direct implications on the Arabian Sea, in light of the impending US/Israeli conflict with Iran.
China is always relevant to this issue/topic, considering Pakistan is China's close ally. Also, there is every possibility, that China and Pakistan may well reach an agreement on Gwadar Naval Base, whereby PLAN could effectively deploy its fleet in the Arabian Sea. As such, it would be beneficial to both China and Pakistan, that Pakistan Navy expand and boost its capabilities.
However, having said all this, for Pakistan ...... it is essential that it focus its attention toward internal political and social stability. For if that is something lacking in the country, then all efforts toward strengthing its military, would be in vain.
