Ukrainian warship A500 “Donbas” and the sea tug A830 “Korets” aiming to Berdyansk arrived in Mariupol on September 24 as the Ukrainian military portal reported.
“The rescue vessel “Donbas” and the sea tug “Korets” arrived in Mariupol as well as two small armored artillery boats R177 “Kremenchuk” and R178 “Lubny”,” the message said.
"Donbass" and "Korets" on Thursday left the Odessa (Western) naval base and headed towards Crimea. Not far from the occupied Sevastopol were accompanied by the patrol ship of the Coast Guard of the Federal Security Service of the Russian Federation "Ametist", and subsequently another unidentified ship joined it.
It is noted that the Ukrainian vessels should be included in the compound, which will be deployed in the new naval base of the Ukrainian Navy, established in Berdyansk. Strengthening the groupings of the Ukrainian Navy in the Sea of Azov is a response to Russia's aggressive actions in the Sea of Azov. According to the agreement of 2003, the Sea of Azov is an internal sea of two states where civil and military vessels under the flags of Ukraine and the Russian Federation can freely enter through the strait and go to their ports.
Ship A500 "Donbas" was built at the Szczecin shipyard in Poland in 1969. The vessels of this enterprise were then considered to be the most enduring, actively used in combat campaigns since the early 1970s.
In the 2000s, the ship was converted into a control ship with the dismantling of the unused equipment of a floating repair shop. On March 20, 2014 the ship was captured by Russian invaders. On April 18, 2014 was transferred to Odesa.
The sea tug "Korets" is intended for towing and canting of other vessels and floating structures in the sea. It was built at the Yaroslavl Shipyard in 1973 and joined the Black Sea Fleet.
