Macrocannon - Imperial Macrocannons: Disruption Macrocannon - This Macrocannon variant fires a "shell" of highly charged, ionized deuterium atoms. These particles cause minimal physical damage to their targets. Instead, they are intended to overload and shut down power transfer systems throughout the target vessel. These weapons are particularly useful for vessels that need to capture their prey intact.Disruption Macrocannon Broadside - These are larger variants of the Disruption Macrocannons, which are mounted on a warship's extended broadside.Hecutor Pattern Plasma Macrocannon - The Hecutor Pattern plasma battery is an ancient variant of plasma macroweaponry that fires superheated plasma rather than a ballistic shell. This variant refocuses the power of the plasma "blast," concentrating it into a compressed photonic packet that can be fired over extremely long distances. It is rare to see these weapons on any but the oldest Imperial vessels, meaning many are found on Heretic vessels lost to the forces of Chaos millennia ago.Mark VI Mars Pattern Macrocannon - The most common macrobattery, these Macrocannons are reliable, hard-hitting weapons that fire kilotonne-grade ordnance, mounted along an Imperial warship's dorsal ridge or in a broadside.Stygies Pattern Bombardment Cannon - As the name suggests, this devastating weapon is designed to reduce planetary defences to rubble and support Imperial military landings on target worlds. Most often the Stygies Pattern Bombardment Cannon uses a linear accelerator to launch massed salvoes of heavy magma bomb warheads, and though it is relatively short ranged, the Bombardment Cannon can also be used in naval combat. Often the simple rumour that orbiting Imperial vessels carry this weapon is enough to force a quick surrender.Stygies Pattern Macrocannon - This variant of the Macrocannon is designed to fire heavier ordnance than the Mars Pattern. These alternative shells contain an adamantium core that cuts through the heaviest known forms of starship armour.Thunderstrike Macrocannon - An older version of the Mars Pattern Macrocannon, these Macrocannons lack the range and power of the later Imperial variants. They are most often found on transport vessels.Deathstrike Cannon - An example of an artillery-grade Macrocannon, this weapon is by starship standards a relatively small Macrocannon. The Deathstrike Cannon is installed as a baseline weapon in the Warlord-class Battle Titan, with the barrel jutting from the shoulders of the massive walker where the head of the Titan normally resides.Lathe Pattern Grav-culverin Broadside - The strange orbital dance of the three planetoids that make up the Lathe Forge Worlds has given the Adeptus Mechanicus Magi there a unique insight into the ancient art of grav-weaponry, using strange forces to hurl warheads at tremendous speeds. Due to the unique methods of propulsion, variant warheads can also be fired through the grav-culverin, including self-propelled ordinance for greater range.Mezoa Pattern Macrocannon - The Forge World of Mezoa has long advocated a modification of the standard Mars Pattern Macrocannons to increase damage at the cost of range and space aboard a voidship.Pyros Melta-cannon - These squat, oversized, and highly-insulated Macrocannons are designed specifically to fire shells tipped with powerful melta-charges that detonate with furious heat.
