Despite what op-ed written by Americans like to repeatedly proclaim, Taiwan does not seem to be in any rush to get rid of its Mirage 2000. And I would dare say that right now, they're probably even less in a rush to get rid of any combat aircraft they have. As long as the airframes are airworthy, they'll keep it in service because they need all the mass they can have to deter China.
Fun fact, to protect Pelosi during her visit, they used Mirage 2000 instead of F-16.
I agree with what you say. But the jet needs to undergo an MLU.
Taiwan has completed an upgrade program of its indigenous fighter fleet, with the last two upgraded aircraft handed over to the country’s Air Force.
He added that France has since sought information from the Taiwanese Air Force regarding the scope of work for any potential upgrade program, as well as the number of aircraft earmarked for the upgrade. However, following the briefing, Taiwan’s parliament decided to freeze funds for the upgrade pending a written report about the program from the service.
This is a pretty serious delay, so it stands to reason there's some weight in the rumour.
Common sense says they need to upgrade it. Dunno how well that will work with politics in the way.
