CN120-26
Introduction 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 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 propellantfumes.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.
Additional specifications *'''Maximum service chamber pressure:''' *'''Recoil effort at trunnions:''' 550 kN (APFSDS fired at +51 °C)*'''Overall weight:''' 2740 kg*'''Recoiling gun mass:''' 1995 kg
