 One advantage of the low-pressure cannon was that, in spite of its relatively large caliber, it could be mounted on a vehicle weighing only 18 metric tonnes, or about 40,000 pounds, combat loaded.The new armament was also fitted with a single-baffle muzzle brake and concentric hydro-spring recoil mechanism as standard to reduce the pressure exerted on the relatively light chassis.According to Textron, it invested in the 90mm Direct Fire Vehicle as a direct response to the Afghan requirement for a more heavily armed MSFV.
