Source: His arse.According to Akbaba their will be a additional order for 4 istifs.
Current Tepe-Class acquisition surpasses a billion dollars, suffice to say well above. The first 4 orders most definitely will be full package consisting of Planar array Triband AESA ESM suite, Full CAFRAD suite, 96 VLS.
However, I am ascertain that the later block will be downgraded to serve as multi-purpose frigate and won't be referred as "Tepe Class". Costing nearly half, 6-8 of these will be procured.
And there will be a final block which will be procured after the multi purpose frigate, and it will be something else, possibly 2 or 3 of these dedicated to BMD.
