It was cancelled when its experimental Mikulin AM-43V engines reached the end of their service life.

Impressed by the performance of the de Havilland Mosquito the Soviets asked Tupolev to modify a Tu-2 as a high-speed day bomber with a reduced crew as the ANT-63.

It was given prototype Mikulin AM-43V engines driving four-bladed propellers, and fitted with new radio equipment.

Bill Gunston says that a Soviet derivative of the German FuG 220 Lichtenstein SN-2 was tested,[1] however Yefim Gordon believes that no radar was fitted at all and the short service life of the AM-43V prototype engines curtailed the planned tests and development.
