Did STM win these contracts on the basis of their offer (best tech for the money) or because it will be used to expand defence ties and maybe offset MILGEM costs by a little. Or was the move political; a shot at France for duplicity in their defense relationship (using Pakistan sales as the worm to lure the Indian fish).
Either way it makes sense to go with STM. If STM had the better package thats a win win for Pakistan/turkey. If it offsets sime of MILGEMs cost then it is again a win win. And ultimately, Why work with a supplier that is notoriously corrupt and underhanded in past dealings. Who has as much propensity to finish the job as they do to embargo your sub while its being upgraded in case of war/hostilities.
DCN is also supplying Scorpene submarines to India and the sensor suites on the Agosta 90B and Scorpene are almost identical. Both subs are equipped with the SUBTICS Combat Management System. It makes better sense to choose another supplier for refits.
DCN also is controversial since there was a leak of sensitive information regarding the Scorpenes.
