Because it would be contrary to how any business works. Business seeks business to make money.Who says Sedef is courting them and not the other way around?
It really isn't. AFAIK Sedef currently only have 2 Istifs it's building. İzmit already launched and is set to be delivered by mid 2027, while Karadeniz is set to be delivered by 2029 at the latest, this is Karadeniz from November, 6 months ago.I concur with you when it is about SEDEF shipyard that is already busy with building ships for our navy.
Until first Tepe gets going, TAIS won't be ordered the follow up ships. Even then, it's not clear if it will be in the same 1 each format like we saw in Istif. Tepe is a much larger, and much more expensive ship. I don't really expect work to start on the first private shipyard Tepe to start before 2030-31, maybe even later. So Sedef must chase exports and civilian vessel contracts in the meanwhile. Sedef built the Anadolu, it can easily build 3 design ready frigates in 3-4 years.
