how much did the G-class frigate cost to acquire for turkey

Turkey’s acquisition cost depends on which G-class frigate you mean, because that label has been used for more than one ship class in reporting. If you mean the British Type 23 frigates Turkey was reported to be seeking as second-hand purchases, estimates were around $25–30 million per ship.

If you mean Turkey’s newer locally built frigates under the I-class / Istif- class program, recent export deals for similar Turkish frigates have been reported at about $1 billion for two ships in Indonesia’s case, while Romania’s Turkish-made Hisar-class OPV deal was reported at €223 million plus €42 million for modifications.

Most likely match

• Second-hand Type 23 frigate: about $25–30 million each.

• New-build Turkish frigates: far more expensive, with recent export contracts around $500 million per ship in one reported case.

Why it varies

• Used ships are cheaper because they may need refit, upgrades, and lifecycle support.

• New-build ships include weapons, sensors, integration, training, and support packages, so the headline price is much higher.

TL;DR: If you meant the old UK Type 23s, Turkey was looking at roughly $25–30 million each ; if you meant a newer Turkish-built frigate, the cost is closer to hundreds of millions per ship.
