it says 8 subs will be ready by 2025 ... even one sub I highly doubt it will be ready by 2025
Here's the actual article.
"The first of the eight new vessels will be delivered by 2025...."
The Taiwanese government has always made it clear that only the prototype will be ready by 2025. Perhaps the first version of the article was mistranslated or the writer confused themselves and only realised after publishing it, requiring a rewrite.
Also delivered does not necessarily mean commissioned. I've read other reports about commissiong in 2026, not 2025. We're talking about half a decade's time, no one can say with absolute clarity how the timetable will have progressed by then.
I smell a F-CK-1 submarine coming. American industry comes with a real turd to satisfy both US government and Taiwanese government requirements.
If it satisfies both US and Taiwanese requirements it's unlikely to be a turd. The US wants Taiwan to have a viable submarine fleet a lot more than it's concerned about a push for the USN to reacquire diesel-submarines. After all these are being assembled in Taiwan, not a US shipyard.
That's why the plan for new submarines didn't go anywhere for over a decade, because previous Taiwanese governments wanted new submarines but didn't want to risk a domestic project going wrong due to the bad PR. US shipyards would have been the only likely place the work could have been done, and the USN was against the optics of seeing diesels being assembled next to their nuclear boats. They were worried Congress would go
"oooh, so you can build these cheaper submarines - we can cut your budget accordingly". Also given that it seems to be a hybrid of the Oyashio and Soryu class, there's even less reason for the USN to feel threatened by this.
The Taiwanese IDF project was limited by the difficulty of getting an advanced engine approved for sale. Whereas here reportedly the US has offered the AN/BYG-1 suite for the new submarines, and the Mk48 and UGM-84s have been previously cleared for sale. That doesn't mean there won't be problems during manufacture that will require fixing, but in terms of internal hardware and weapons there's a lot less reason to be pessimistic compared to the F-CK-1.
