I don't think I've seen so many "guests" in a threat before 
I think we are going to have at least enough Kaan to completely replace F-16s in the future, so, around 250-300. But I do like the idea of a single engine naval TF-X, much much more than naval Hürjet. Aircraft carrier is a project for late 2030s - 2040s at best, so we are should have more than enough time to get started on Kaan serial production and design a naval stealth fighter based on its design. Double seater drone commander is an interesting idea as well, could combine beautifully with Anka-3/4 and KE, but I'd be happy with a single seater as well.IMO, Kaan will not be produced in large quantities like the F-16 due to manufacturing and operating costs. IMO, we need another fighter that is suitable for mass production and is cost-effective.
This fighter: 1) capable of controlling drones, i.e. double seated, 2) stealth&navalize, 3) must be single engine.
