I get your point, Yes T129 is not designed for MILDAR, and there is a certain trade-off if you want to add it. Plus MILDAR is mostly for conventional war, like Longbow Radar (Anti-armor operations), so it is not an urgent requirement, and yes Atak-II will have more payload capacity to carry it (although 3D render model does not show us the MILDAR!). I hope it won't be placed on hard points like in the photo.
However specs of AW249 and Atak-II shows that these will be
light attack helicopters as well, just a bit improved, neither of them planned to have stronger engine and 7-8 tonne still counted as light, so it cannot be an alternative to Apache or Mi-28(MTOW-10+). Both of them are in the same class with Tiger, Rooivalk etc. Atak-II will probably have TEI 1400shp engines which are quite similar to current engines, in addition LHTEC is very optimized and light engine which makes T129 one of the lightest and cheap to operate helo with decent payload. I don't think TEI engines will be lighter than LHTEC or have a better performance unless they think third engine as a solution. It will be the first helicopter engine designed and produced locally! don't expect much from it. Atak-II will be heavier but probably with heavier engines. The reason for Atak-II would might be having more control over it, having stealthier design, better flir placement (AW249 making same mistake), more "milli" design, a bit! better payload! and for export without restrictions.
I think Atak-II should be heavier, because we have T129 as light attack and COIN. Turkey needs anti-armor chopper too. (More powerful engines or third engine, 30 mm cannon, payload of 1800 to 2000 kg, may be 16x Umtas) Compete with AH-64 Mi-28 Ka-52
@Kamil_baku For the radar, I think as an EU and NATO country, Poland or Italy could easily outsource and integrate Longbow like radar, they don't need to re-invent it.
Lastly, Leonardo and TAI have collaboration on multiple programs and Leonardo will definitely use experience gained from T-129 to develop AW249. So I expect some sharing and collaboration on Atak-II and AW249 programs too. And similarity of specs suggests possible rivalry in export market too. T129 is lighter and cheaper than Tiger, but it is not a fully local product, but A129 still exists too, so Poland made a good decision.
