Well,,, that's your opinion.
Have you ever worked wth the engineers and researchers in Taiwan?
I have. IN the mid to late 1990s.
They are smart people and know what they are about.
If they feel they need these upgraded vessels with more heavy air defense along with their powerful anti-surface weaponry, to go along with the numerous modern FACs (actual small missile boats) they have already built, then they have plenty of good reason to.
Whether you think they should or not.
...and I think the cost for twelve of them will end up being appreciably less than 2 billion US dollars.
Time will tell.
Given that the follow up batch of three will cost about $150 million a piece, lots 2 and 3 with the TC-2 are almost certainly unlikely to cost less than that.
Now, my point is, if they want a FAC squadron leader with some level of area air defense, a monohull would be a much more practical option (if nothing else, physics tells us that catamarans with a high center of gravity are a bad idea). And frankly, a 1,000-1,500 ton monohull probably is going to cost as much as a 700 ton catamaran.
Now, as to why anyone would want to build a 6,000-8,000 ton DDG with only 32 VLS for operations in the Taiwan Straits, I'm genuinely flummoxed on that one.
