Work on overhauling T-64 tanks has started at the Polish arms plant Bumar-Labędy as part of the agreement between the Polish arms concern Polska Grupa Zbrojeniowa (PGZ) and Ukroboronprom [Ukraine’s Defence Industry – ed.]. Cooperation in the maintenance of T-72 and PT-91 tanks, which were transferred to Ukraine by Poland, is also planned in the long term. The possibility of joint work on the maintenance of Leopard 2 tanks, which were transferred to Ukraine by the international coalition, is also being considered.
