This page is about the French tank cannon CN90 F4 (90 mm). For other versions, see CN90 F2 (90 mm) and CN90 F3 (90 mm).


The CN90 F4 (otherwise known as the Super 90) is a 90 mm smooth-bore cannon manufactured by Nexter. The Super 90 is based off of the earlier F1 and F3 versions and compared to the earlier versions, it is way lighter and has higher muzzle velocities, while also being 19 calibres longer than the earlier version of the cannon.

General info

Both the barrel and the breech are made from ESR (Electro-Slag Refined) steel, a process which adds more polish and toughness to the steel, while the vertical wedge breech is inclined at an angle of 35° to allow easier, and faster, reloading.

In case maintenance is required, the breech mechanism and the recoil mechanism have been designed in a way to allow quick and easy maintenance without having to strip down the cannon completely. The breech mechanism itself is made from modular assemblies while the recoil mechanism is made up of smaller subassemblies, which aid in the quick and easy maintenance.

A thermal coat is also added onto the cannon to help withstand higher temperatures without the barrel deforming. At the end of the cannon, a single-baffle muzzle brake is added to aid with recoil.
