A further development of the experimental tank Object 237. The Object 244 featured a more powerful gun. The fighting compartment was slightly changed: the radio was placed in a turret recess, a more efficient fan was installed, and the ammo rack and periscopic sight were modified. The driver's compartment and engine-transmission compartment were not modified. The vehicle never entered service due to problems with the gun barrel.
