The CN120-26, also simply referred to as Modèle F1 (F1 model) is a French smoothbore 120mm tank gun of 52 calibers designed by the EFAB of Bourges and produced by Giat Industries .

Description

[edit]

The 120 mm smoothbore gun F1 has been designed for installation in the Leclerc main battle tank. The smooth-bore gun is chrome-plated, fitted with a thermal sleeve and has a vertical sliding breech mechanism. It is also fitted with a muzzle reference system (MRS) and the tropicalized variant of the Leclerc is fitted with a compressed air system for removing propellant fumes.[2]

In the Leclerc application, the gun is fed by a 22-rounds bustle-mounted automatic loader designed by Creusot-Loire Industries. The 120 mm F1 gun fires the same 120×570mm ammunition as the German Rh-120 and American M256 smoothbore guns. The French 120 mm F1 gun is, however, 1 m longer than the L/44 version of the Rh-120, which increases muzzle velocity and armour penetration of APFSDS projectiles; it also gives a longer effective range.[3]
