Hyper-Velocity AutoCannons

Jump to: navigation, search

The Hyper-Velocity AutoCannon (HVAC) is a modernization of the standard AutoCannon line-up.


HVACs improve upon ACs of the same caliber by offering longer range and a slightly higher bullet velocity, for example, the HVAC2 has a range of 1500m, compared to the AC2's range of 1000m. Only Inner Sphere units use the HVAC weapon system.

HVACs currently come in the /2 and /10 calibers. There is no HVAC equivalent to the AC20 in MWLL, and HVAC5 can only be found on the Behemoth "F" Tank and Orion "D", as for all others it hasn't been implemented in game due to it being redundant to the Light Gauss in role and performance.

Gameplay & Hints





Hyper-Velocity Autocannons are ballistic weapons first developed by the Capellan Confederation in the 3050s based on standard Autocannons common to many Inner Sphere units. HVACs feature an extended range in comparison to standard ACs of the same calibre without sacrificing damage output. In order to carry the propellant necessary for the shells to travel so far, each HVAC round is larger than its equivalent AC counterpart, meaning that less ammo is carried per ton. This difference in the type of round required also means that HVACs are incompatible with the specialized munitions available to regular ACs such as precision or armor-piercing rounds.
