During the early '50s, a design proposal for an upgraded MiG-15, titled the MiG-15bis (second), was issued. The main upgrade was the new VK-1 engine, offering considerably more thrust. The MiG-15bis saw massive export to almost every corner of the world, and the neighbouring Eastern Bloc was no exception. The Hungarian Air Force was one of the primary MiG-15bis operators of the time, and was also one of the countries acting as an "interceptor net" for the USSR. As a result, Hungarian MiG-15bis aircraft took part in many interceptions of NATO aircraft probing in their airspace. This culminated on 19 November 1951, when MiG-15bis pilot 1st Lieutenant A. A. Kalugin forced a USAF C-47 to land at the Hungarian airbase at Pápa, after it had penetrated Hungarian airspace. The Hungarian MiG-15bis would serve for many years before eventually being replaced by the MiG-17 and MiG-21 for the frontline fighter and interceptor roles respectively.

Introduced in Update "Alpha Strike", the MiG-15bis (Italy) is a Hungarian operated copy of the MiG-15bis found in the Hungarian sub-tree of the Italian tech tree. The Hungarian MiG-15bis is a identical copy of the one found in the Soviet and German tech trees, and performs identically to them. Having the powerful VK-1 engine and strong firepower, the MiG-15bis shines with its overall performance against a majority of jets that it faces, though it still requires attention to enemy missiles and strong trigger discipline for the limited ammunition onboard. Alternatively, in full uptiers, it can form the backmarker of the team rather than the tip of the spear, picking off distracted targets and being able to fight back against even some supersonic jets in close-in dogfights due to its incredible dogfighting performance for its speed and weight class, along with being a very small target to hit.
