I thought since the F-4. 0 is on order & the same would be available from 2023-24 onwards, the production would commence then.In France, according to the articles, the start of deliveries will be in 2026 or 2027. This means that production will start in 2023 or 2024.
A normal start would be in 2022 because we are at the end of 2021 and there is still the down payment to be made for the contract to come into force (€2.25 billion anyway).
I think that a second assembly line is also needed, which would explain a year's delay, and finally there are probably specific developments for the UAE.
