Trials were initiated, but before they were completed it was decided to return the Morozov design team to Kharkov where the former Zavod Nr. 75 Diesel Factory was to be re-established as a tank assembly plant.
Further design work continued there and the T-44 was accepted for production in 1945 as an eventual replacement for the T-34-85.
Up to now, it's unclear whether the T-44 saw any action during WW2, although some sources state that three samples were deployed during the final weeks for testing.

The T-44 formed the basis for the post-war dynasty of the T-54, T-55 and T-62, and T-55 production did not cease at Zavod Nr. 13 in Omsk (formerly Zavod Nr. 174) until 1981.
In many respects, the T-44 was the most advanced medium tank to have emerged from the Second World War.
The initial versions had transmission problems which were rectified in the modernized T-44M after the war.
It did not completely replace the T-34-85 on Soviet production lines until 1947 when the improved T-54 entered production.
