Zelensky says drone manufacturing will enjoy priority in the budget now that they get the €90 billion from the EU.

I'm fairly sure it's not just for Ukraine, but they got contracts from the Gulf States to help them rearm their air defence.

So how I see it, Ukraine has a product - or rather privately owned companies have a product but no production capacity, so the Ukrainian state will use the money that the EU takes as a loan and gives to Ukraine and build the factories for these companies to sell weapons to the Arabs and the Ukrainian state. The owners of said companies and shareholders surely will earn well.
This could take some time however. Plus surely Russians will target these factories unless they are built outside Ukraine. I guess there are some places to build them.
