On 20 August 2016, Aydın class mine hunter TCG Akçakoca entered Georgian waters for a sad mission.
According to Agenda.ge, Corporal Iago Sharadze and First Class Private Giorgi Nanetashvili were taking part in dive training on August 16 but failed to surface after the planned dive, which took place off the coast of Gonio in the Black Sea. The men’s bodies have not yet been found but they are presumed dead.
As a mine hunter TCG Akçakoca has the suitable equipment on board, to find small objects underwater. Thus sending her for search of the bodies of the Georgian soldiers was very appropriate. According to initial news, she was to stay in Georgia for 3 days. I could not find any news whether she has returned or not.
Georgian Defence Minister Levan Izoria visited the TCG Akçakoca.
“I met with the crew of the Turkish vessel. They are highly skilled and professional specialists. The vessel is equipped with high technology and modern rescue capabilities which makes possible to conduct the operation effectively. Readiness is huge. They intend to stay for three days. Thus, in case of necessity the rescue operation will continue”, said Minister of Defence Levan Izoria.

THIS WAS A TRAGIC TRAINING ACCIDENT.
Very tragic. My understanding is that the bodies are not recovered yet.
