Hydra Flak Tank

Jump to: navigation, search

The Hydra Flak Tank is an Imperial Guard self-propelled anti-aircraft vehicle based on the Chimera chassis. Employed when Imperial Navy assets are unavailable or air-superiority is in the balance, Hydras provide essential anti-air protection for their regiment and can also serve in a ground support role, where they are effective against infantry and light vehicles.[1][2][3]

The Hydra Flak Tank in action.


Manufactured on hundreds of Forge Worlds, the Hydra is a specialised vehicle used for mobile air defence, protecting important sites and columns from air assaults. Its Machine Spirit-assisted automated turret contains targeting and tracking equipment, including a predictive logic-engine, which allows it to lock onto and track enemy aircraft regardless of any evasive maneuvering. These control four long-barreled Autocannons firing heavy calibre, high velocity explosive rounds capable of firing six hundred rounds a minute,[6] shredding through enemy aircraft fuselages thanks to their high rate of fire. When used against infantry and light vehicles these rounds are equally devastating, allowing even a single Hydra to decimate entire formations in a heartbeat. While the use of a Hydra in this role is a breach of official regulations, Imperial commanders often overlook such infractions.[1][2][3]

The quad autocannons are operated by dedicated gunner, who sits in the turret along with a loader to assist the auto-loaders, while the vehicle commander, driver and a comms operator sit in the main hull and share control the hull-mounted Heavy Bolter.[1][2]

Each regiment usually groups its Hydras into a single company, though this is more often for administrative purposes than anything else. Squadrons of Hydras or even individual vehicles will be parceled out to different units for air defence, with artillery given first priority for any available units, followed by tank companies and then HQ units and supply depots, though often static targets will be protected by Hydra platforms instead.[1][2] However, some regiments will consist entirely of Hydras. These 'heavy air defence regiments' will usually be split up and attached to different units and locations across an entire warzone, though occasionally it will fight as a single unit.[3]

Technical Specifications

In addition to its two twin-linked long-barrled Autocannons and auto-targeting system the Hydra is also armed with a hull-mounted Heavy Bolter, as well as Smoke Launchers and a Searchlight. The Heavy Bolter is sometimes replaced with a Heavy Flamer, while other modifications include Camo Netting, a Dozer Blade, Extra Armour, a Hunter-killer Missile, and/or a pintle-mounted Heavy Stubber or Storm Bolter.[3]
