Thanks but you might have misunderstood my question. There were two different design and two proposal. Above I shared 2 images of 2 different designs (FAC and MPAC)
Construction more looks like FAC design rather than MPAC.
Final FAC design is a further upgraded MPAC. MPAC was one of the runner ups for the FAC tender, but it is not the final version. And to be honest looks like the design changed somewhat again looking at the bridge and the mast. Ship that's being built more like a mini Istif more than the released FAC design.
The rest of FACs will be build in groups or one by one ? which will take so many years like Reis class submarine ?
Not even getting into the delays on Reis production, submarines by their nature are very slow to build. It's very normal all over the world for submarines to be built in 4+ usually 5-6 years from keel laying to delivery.
First ship of TTHB(Turkish FAC) is a prototype of sorts like we had with Heybeliada and Istanbul. We will probably see a block order of ships once the first ship goes further along building phase. As the first ship is being built by STM with TAIS, we might see a 3+3 order like we saw with Istifs but unlike frigates, our FACs don't need that kind of fast replacement schedule.
