XM360

The XM360 is an American experimental 120 mm tank gun developed by U.S. Army's Watervliet Arsenal, Benét Laboratories for use by General Dynamics Land Systems (GDLS) on one of their proposals for the Future Combat Systems (FCS).

It was developed as a lightweight cannon that could equal or surpass the capabilities of the 120 mm M256 mounted on the M1A2 Abrams while being mounted on a much lighter vehicle. To achieve this the XM360 combined technologies such as Electrothermal-chemical technology (ETC), a gun tube with composite overwrapping and a modular recoil mechanism coupled with a muzzle brake.

The XM360 has the capability to fire the same standard 120 mm NATO ammunition as the M256 while also being able to fire munitions such as the indirect fire laser guided Mid-Range Munition (MRM).
