Description
[edit]The 120 mm smoothbore gun F1 has been designed for installation in theLeclercmain battle tank. The smooth-bore gun is chrome-plated, fitted with athermal sleeveand has a vertical sliding breech mechanism. It is also fitted with amuzzle 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 byCreusot-Loire Industries. The 120 mm F1 gun fires the same120×570mmammunition as the GermanRh-120and 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 ofAPFSDSprojectiles; it also gives a longer effective range.[3]
