In 1934 the DML (Division Légère Mécanique) was formed and the army wanted a light tank to be used with the Somua S-35. In 1933 the infantry ordered a light tank to be produced and Hotchkiss developed prototype in 1934. This was initially rejected by the infantry who went with the Renault 35. The calvary did accept the design for its DCs (Divisions Cuirassées).
Became standard char leger (calvary tank) in October 1936. The Calvary received 300 and the infantry 100.
There was no turret floor in the H-35 and the commander sat on a saddle which was suspended and moved with the APXR.I turret.
Hull and turret were cast armor.
The suspension had 3 scissors with horizontal coil springs. It was steered by using a Cleveland differential with front drive sprockets.
