The Turбn tanks were a series of Hungarian medium tanks of World War II. They were produced in two main variants: the original 40M Turбn (or Turбn I) with a 40 mm gun and later the 41M Turбn (or Turбn II) with a short-barreled 75 mm gun, improved armour and a new turret. A total of 424 were made. The 40M Turбn (Turбn I) was originally inspired by and used the technology-based solutions found on the design of the Czechoslovak Љkoda T-21 medium tank prototype. The Turбn tanks fought on the Eastern Front against the Soviets, and in the defence of Hungary.
A further upgraded prototype variant, the 43M Turбn (or Turбn III) was also developed and constructed but did not go into mass production. This had a powerful long-barreled 75 mm gun, further improved armour and again had a new turret. Prototypes were manufactured, but work on the project stopped in 1944 when the mass-producing terminated in the country.
