Best option is to get naval version of Pantsyr M system from Russia.
Pansyr-M is a naval version of the Pantsyr. A mock up of this system was demonstrated in 2015 and production commenced during the same year. This system can engage four targets simultaneously with missiles and its...
The Buk-3M’s target-destruction probability has reached 0.9999 and its maximum destruction range has been increased by 25 kilometers and now stands at 70 kilometers.
What are the modifications required to customize the Su-35 to work in PAF environment? Whether PAF require AESA radar in place of PESA radar in Su35? Whether Russia will allow integration of SD-10, LD-10, PL-10, CM400 & RAAD missiles in Su-35?
Just like Super Mashak, Super K-8P should also be considered with L-15 style cockpit, HMDS, A-Darter missile & ECM/Aselsan pods. This will increase its capability and sale in African and other middle east countries.
Without AESA and Aim-9x, block-52 are nothing against Rafale and Su-30mki. By the way, other F-16s are also MLUd and are at par with block-52 in avionics.
Design of J-31 has completed and may be only minor modifications are required. So its better to get the engine & frame from China and give contract to TAI for the incorporation of Turkish avionics & sub-systems into it.
