The Black Sea Naval Force (also known as BLACKSEAFOR or the Black Sea Naval Cooperation Task Group) is a Black Sea naval cooperation program established in 2001 on the initiative of Turkey with the participation of Bulgaria, Romania, Ukraine, Russia and Georgia.
[1][2] The original purpose of BLACKSEAFOR was "to cooperatively promote security and stability in the Black Sea maritime area and beyond, strengthen friendship and good neighborly relations among the regional States, and increase interoperability among those states' naval forces".
[3] The BLACKSEAFOR has conducted several joint naval drills since its formation, however it has been suspended several times.

[6] In 2015, after a Russian plane was shot down by Turkish forces, Russia suspended its BLACKSEAFOR membership.
