A primary anti-aircraft asset, the Hydra is a flak tank equipped with an array of specially adapted autocannons. Many Imperial tanks are vulnerable to attack from the air, making the Hydra highly valuable to an armoured force. Once its predatory logic-spirit locks on to enemy aircraft, even the most evasive targets cannot escape the Hydra's storm of shells.

This multipart plastic kit builds one Hydra – an anti-air vehicle equipped with a quad autocannon array. The Hydra also sports a hull-mounted heavy bolter or heavy flamer, and features a firing platform to its rear with components to build a gunner and a crouching spotter. Other accessories are included to customise your vehicle, including spare ammo and fuel.

This kit can alternatively be used to build a Wyvern – a mortar-armed suppression tank for the Astra Militarum.

This kit comprises 100 plastic components, and is supplied with an Astra Militarum Vehicle Transfer Sheet featuring tactical markings, numerals, and other regimental heraldry.
