Burak-class corvette (Turkish: Burak sınıfı korvet), aka B-class corvette, is a warship class of the Turkish Navy, all ex-D'Estienne d'Orves class A69 type Aviso corvettes, mainly designed for coastal anti-submarine defense and ocean escort missions. Their robust design and economical propulsion system allows them to be used for distant overseas operations. A total of six ships under the Burak-class are being operated by the Turkish Navy and will be phased out with introduction of Ada-class corvettes.
