Domestic Variants

 * T-57AG: Mostly identical to the Stasnovan T-57A. During the early 1950s, several thousand T-57A tanks were provided to the Granzery People's Army, in 1971 the nomenclature PcKTr-38S1 was adopted for this model.
 * T-57AG-2: Starting in 1952 Granzerian manufacturers began to domestically produce the T-57 with Granzerian parts. Because it was of higher quality when compared to the Stasnovan produced T-57A, it became a hit on the export market. Unlike the original export T-57AG, it had a redesigned engine access plates, three plates fitted to the hull to reduce track shedding and oval engine grills in the engine decks. In 1971 the nomenclature PcKTr-38S1-2 was adopted.
 * T-57AG-3: Granzery upgraded T-57AG-2 with Granzery-produced laser rangefinder, fire control system and wind sensor mast with thickened center section mounted on rear of turret roof. It was adopted in 1964. In 1971 the nomenclature PcKTr-38S1-3 was adopted.
 * PcKTr-38S2 was a 1970s modernization of the basic T-57A tank. The T-57AG-3 tanks received Granzery-produced "Kalapács" fire control system, thermal sleeve on gun, replacing the 7.62mm PKM with a Granzery produced 7.35mm GP63 machinegun, a laser rangefinder, mounted over the barrel, inside a large rectangular armoured box. Granzerian tanks were also fitted with BDD add-on armour blocks on the turret front-sides area and glacis (known as the "horse-shoes"). The BDD armour panels consist of armoured steel boxes filled with Penpolyurethane and thin HHS steel plates. The BDD semi-reactive armor adding 120mm of protection against APDS and 200-250mm of protection against HEAT ammunition, thus these tanks had similar protection as early versions of T-74. The tanks also received an upgraded 650 hp engine. The PcKTr-38S2 tanks were the primary armoured force of the Granzerian forces during the Transkarpatian War of 1975, facing against the newly adopted Stasnovan T-74A, the tanks proved capable although inferior firepower proved a challenge compared to the T-72s superior 125mm gun.
 * PcKTr-38S2-2: The PcKTr-38S2-2 was a 1977 attempt to increase the firepower of the PcKTr-38S2 with a more powerful 120mm main gun. The T-57 chassis proved incapable of handling the larger calibre gun, and a smaller 110mm PL 76M rifled gun was installed to increase the firepower of the PcKTr-38 model of tank. In addition the S2-2 was equipped with an upgraded fire control systems.
 * PcKTr-38S3: The PcKTr-38S3 was a 1983 modification of the PcKTr-38S2-2 with an extended chassis involving six road wheels instead of the usual five, the extended chassis allowed the installation of a significantly more powerful 870 hp engine.
 * PcKTr-38S4: The PcKTr-38S4 was a significant upgrade of all systems in 1986, retaining the same gun and engine as the S3, most notably was the installation of the Küklopsz fire control system (with cross-wind sensor, laser rangefinder and night vision), FRLSV laser warning receiver that can locate and identify incoming threats, warning the crew and triggering countermeasures automatically.
 * PcKTr-38S4-2: The PcKTr-38S4-2 was the final upgrade of the PcKTr-38 in 1997, with a Küklopsz-K advanced fire control system and replacing the applique BDD armour panels with applique first-generation TEKNŐ Composite Armour panels providing significantly more protection.
 * T-57AG-9: The T-57AG-9 was an extensive 1999 upgrade of the PcKTr-38. It's based on the PcKTr-38S2-2 and is almost identical with the exception of the engine, a comprehensively upgraded optics and fire control suite, special composite armor, and Huzat-A explosive reactive armor. The tank is powered by a two-stroke liquid-cooled multi-fuel supercharged diesel engine with boxing pistons developing 750 hp and has maximum speed of over 70 km/h on the road in forward gear and over 30 km/h in the reverse gear. Is not being considered as an option for upgrade by the Granzerian Army, but has been adopted by the Sytrican Armed Forces.
