To answer trolls who are biting at our heels, if Bangladesh WANTED something like the Makassar class (which is not a full-on LHD in my opinion), that can be afforded very easily, no question. I'm going to go out on a limb and willing to bet we can even afford something like the
Dokdo Class,
which IS a proper mini LHD, unlike the Makassar class, as handy that platform is.
But affording something like the US WASP class LHD's (Like the USS Makin Island) which are the definition of a real LHD, along with all the Naval S-70's, LCAC's and LCU's that come with it will be out of the question.
As
@DalalErMaNodi bhai noted, you need supporting armed craft like frigates or destroyers to complete an armada, LHD's don't operate on their own.
I don't see ourselves invading hostile foreign shores with LHD's, Myanmar is not a proportional threat needing an LHD.
ROKS Dokdo
WASP class LHD "USS Makin Island"
To go with a complete LHD invasionary force, you'd need all the things that go with the LHD, such as training, skills, discipline, and most of all equipment such as Large Chinook-size troop carrying Helicopters, medium sized helis like the S70 class, Landing Craft LCAC's, Hovercraft, amphibious AFV's and tanks to make a hostile shore landing.
Before pulling the LHD trigger (In the future), our Navy needs to ask, does this fit our Naval doctrine for invading foreign shores with an expeditionary task force? What are the possibilities of success and the actual outcome? Are the losses involved worth the gain?
One needs to match the tool with the task at hand, not spend Millions to have it - so it can only be paraded on victory day like the Royal Barge mini aircraft carrier of Thailand.
