In 1999, the KhKBM developed a number of technical projects to strengthen the security and modernize the fire control system of T-64B (T-64BV) and T-64B1 (T-64BV1) tanks to the level of T-80UD (T-84) tanks. At the same time, three options for the modernization of tanks of this type were developed. Experimental modernized tanks were demonstrated in the city of Kyiv on August 24, 1999 in a parade in honor of the 8th anniversary of the Independence of Ukraine.
