Entirely indigenous, although that tends to mean 'with some under-the-counter input from Japan and the US'. In service since 2008, IIRC, and has both land-to-sea and ship-to-ship variants.
Certainly the propulsion and guidence systems seem to be top class. How the anti-countermeasures suite copes with PRC defensive kit is obviously not something they're keen to reveal much about but I think it's fair to say that anything coming out of Taiwan that relies on hi-spec microcircuitry will be pretty decent.
Incidentally, a quick scan on the Taiwanese English language press reveals only one other publication mentioning this weapon this week, and then only in passing in an article on the proposed 'Sunny' deep-strike missile system. Taipei Times, which is the original source of the story, is staunchly in the 'pan-Green' independence camp and never misses an opportunity to sling mud at the majority-KMT government.
There's a Presidential election coming up in Taiwan next year and the main pan-Green candidate (Tsai Ing-Wen of the DPP) hasn't revealed much of substance about her policy platform, so now would be a great time to scupper the F-16 purchase by giving the Yanks an excuse to say the RoC armed forces can look after themselves. Then the pan-Greens could slag President Ma off for "failing to protect Taiwan" by not securing the deal - yes, they're just that childish.
The Chinese really wouldn't need carrier aviation to bomb Taiwan. They could do it from home, they'd need to do some AAR but I suspect it'd be within their capabilities.
Once they get their tankers and AWACS squared away which is probably the PLAAF main effort at the moment they could really smash them. Can't see it happening anytime soon though given the reaction it'd get from the US.
If the Prc had really wanted Taiwan it would have got it years ago. Reaction from the US? I doubt that it would start a nuclear war with China and it's not going to 'win' any other way. Political posturing. Drive on.
The PRC and indeed all the incarnations of China before it, have always played the long game. Having serious capital ships and a blue water capability is just one more demonstration of the emerging super power. Not this year, not in ten years, but perhaps in a hundred years (I nearly typed 50) and China will be the dominant nation state on the planet (If we haven't killed ourselves off by then).
Where carriers come in to any invasion plan for Taiwan is to stand-off and interdict any Japanese naval interference from the north or USN from the Phillipines, while their amphibious forces circle round the island and land on the less populous and more easily broached beaches to the north or east.
My theory is based on the number of people of Chinese origin in the world. If you pay attention to those around you, you will see alot of people who could be Chinese. One day they will put up a candidate to be an MP in all constituencies. We will then be taken over. The Canadians have already seen this and limited immigration from China. That they have everyone's money/bonds is incidental.
Militarily, it's an incredibly tough nut to crack and always has been. The terrain is pretty much all 'no-go' except for strips down each coast where it's 'slow-go' at best. Down the west coast, it's incredibly urbanised and not easy to make an opposed move through. Just as an example, the Truku tribe of aborigines tied up 20,000 IJA troops with an insurgency in the 1920s. There were less than 2,000 of them, they were armed with bamboo spears and bows & arrows but the Japs had to use aerially-delivered poison gas to finally subjugate them.
True, the PRC could reduce the island to glowing slag but that wouldn't be their war aim - they want to exert jurisdiction over the territory currently controlled from Taipei; and finally end what they see as foreign interference in Chinese affairs by drawing a belated conclusion to the civil war. We might be blinkered by the label 'Taiwan', but it's still the Republic of China as founded in 1911 and currently comprising the 'free areas of Fukien and Taiwan Provinces'.
I dont remember a colour for missiles which come through your door. I guess you have to lauch it with a pot plant to the west and hope your opponent doesnt have a mirror opposite the door you are aiming for
