Which roughly means:
"Kharkov Armoured Repair Plant "specialized in the overhaul and modernization of the T-64, T 80, T-72 tank engines 5TDF and GTD-1250. Plant also overhauled tank sights, laser range finders and a range of guided weapons. At the time of the collapse this Soviet factory produced approximately 60 tanks,and repairs 55 engines per month.
So i assume this repair plant was given up when the Ukraine gained independence from the Soviet Union in 1991.
