Thus, the proposed Romanian vehicle was to include elements comparable to those of German armor that were considered superior to those of Soviet tanks.

[3] British historian Mark Axworthy states that the Romanians had planned to locally produce the Soviet T-34 with some gun technology changes incorporated from the German Panzer IV, and that wartime leader Ion Antonescu himself proposed this vehicle.

[1][4] However, an original Romanian medium tank was also proposed, whose characteristics were partially comparable to those of the aforementioned Soviet and German tanks: Its planned weight was of 16-18 tonnes; it would have been able to reach 50 km/h; the crew would have consisted of four members; the main gun was to have a caliber of 50 mm or higher; secondary armament would have consisted of one or two machine guns; the armor was to be 40-60 mm thick; and the height of 2 m or less.

The first such proposal came in 1926 as an offer by the Reșița works to produce a British Vickers tank under license, weighing 10.5 tonnes and reaching 24 km/h[7] (which indicates it was the Medium Mk.

[8] During World War II, in 1940, Romania applied to Germany for a license to build a local version of the Škoda T-21 tank in 216 examples; this planned vehicle was designated R-3.

It is possible that it would have been heavier, had it been produced, or that it would have been small in dimensions (as was the Mareșal tank destroyer, developed in parallel, which stood at only 1.54 m tall[11]).
