Modified TF-2000 class would be OK design wise, however Turkish Navy ships use mostly NATO type armaments, either standard US stuff or license-made equivalents in Turkey such as RIM 116s and ASROCs. That is very different from what we have in our Navy now. I don't know how Pakistanis plan to integrate Chinese missiles and armaments into Turkish Milgem vessels. Maybe Brother @cabatli_53 knows.
Good question also for maybe @Quwa bhai. Thanks in advance for any details/pointers.
Also - TF-2000 cut down to 6000 or so tonnes will still cost North of $2 Billion each projected, which means cost can spiral upwards. Is that within reason?
Well the latest estimate for each 9000 tonne TF-2000 destroyer is 1 billion US dollars. No way that the build cost is as high as 2 billion US dollars and that figure probably includes the development costs.
If BN was to go for a cut-down 6000 tonne frigate then expect the price to come down to 6-700 million dollars each and that seems to be affordable for BN if the ships are delivered from 2025-2029.
As to problems with the weapons system, remember that nearly all will be replaced with indigenous Turkish ones from 2025 onwards. Only thing that BN will really have to wait for is the long-range Hisar-U, most of the rest should be available with the first delivered vessel.
It may be a challenge to get everything worked out and both Turkey and BD will have to be imaginative but this now looks like the best way to go with the massive delays already to this programme. BD should forgo both Chinese and Western options and go Turkish for it's next-gen frigate programme.
