Three different designs were presented at paper or mock-up stage: the B2 (35 tonnes, 40 mm of armor), B3 (45 tonnes, 50 mm of armor) and BB (50 tonnes, 60 mm of armor). From four prototypes presented in 1924 – the Char de Bataille FAMH, FCM, SRA and SRB, the Char de Bataille program evolved towards the B1, of which the first prototype, mild steel n☁01, was completed by Renault in 1929.Īt the time, the B1 was a 25.5 tonnes vehicle with a hull-mounted 75 mm and two turret-mounted machine-guns, and envisioned to have 40 mm of maximum armor Though this was already considerable for the time (and during the development of the B1, the Geneva Conference, which discussed banning tanks over 20 tons, was a major hustle to overcome), a program calling for an even heavier tank was formulated in October of 1930.

Early 1930s: toying with a heavier Char BĪ major program of French armor through both the 19s was the Char de Bataille.
