The main power plant is mechanical, two-shaft with two diesel units 12ZV40 / 48 Zgoda Sulzer with a capacity of 8000 liters.

The units transmitted rotation through the side shafts to two four-bladed, low-noise variable-pitch propellers (RSh).

On September 25, 1985, while passing the Bosphorus in heavy fog, Khasan (sailing with all the proper precautions and signals) rammed and cut in half TCG Meltem, when overtaking her at an angle to its course.

Soviet sailors rescued 13 people (according to Turkish data, 14 people): ten from the water and three more from the half-sunken bow of the boat that floated like a float (they were rescued by divers from a training ship who climbed inside the flooded compartments).

She was temporarily detained by the Turkish authorities until the circumstances were clarified, but the results of the investigation showed the guilt of the Turkish boat commander, who did not follow the rules of sailing in narrowness in bad weather (the navigation radar was even turned off, and its operator was resting in the cockpit).
