2 ORKA torpedo or ÇAKIR missiles / Equivalent weight bombs
ESM, SAR/GMTI-ISAR, EO/IR,
Built-in/Internal sonobuoy launcher/room,
Airborne magnetometry (MAD),
SATCOM, CDL antennas, MWS, expendable countermeasures etc. And some more other of internal avionics and may be CMS. I think even if all these are optimized and well-packaged payloads for the UAV, a lifting capacity of around 2 tons is required.
TAI is a very experienced company in both MPA system integration and UAV development. If the lifting capacity of AKSUNGUR can be increased above 1.5 tons with turboprop engines, we may see the world's first all-in-go unmanned MPA aircraft concept. Or a long-range and very high endurance unmanned maritime patrol concept consisting of two aircraft, one at ordnance drop altitude and the other at high altitude.
Earlier plan was to operate Akıncı-Aksungur together, Akıncı carries the weapons, Aksungur carries the sensors. However Navy wanted to operate MS500 (Akıncı-C) version to withstand harsh weather conditions and with a bigger payload.
I am not sure if this was a confusion of drones, where Aksungur is mentioned in place of Akınıcı or Navy has changed their idea and intrigued by integration of the Advent ROTA / MARTI on the Aksungur along with sonobuoy processing unit etc. Sooner or later Baykar will have to integrate Advent on drones which they are supplying to TN. TN's red line is the integration.
In the end we will have this formation;
Manned MPA, in safe zone
Uplinked patrol MPA-UAV equipped with sensors, sonobuoy receivers and TDL relay and possibly with limited number of Sonobuoys
Uplinked, Depending on mission, an UAV dedicated to carry high amount of Sonobuoys.
Uplinked assault UAV equipped with Atmaca, SOM-J, SOM-C, Çakır, Winged ORKA or winged lighter Torpedo.
Doesn't matter whether Aksungur TP or Akıncı-C.
This is only the aerial scenery. These UAVs will be also accessible by assets of TN and every ship will have a team of UAV-USV specialist.
