The Vulture Gunship is a purpose-built variant of the Valkyrie STC; a high-speed, low-level hunter-killer, capable of mounting a wide range of payloads to carry out its assigned mission. Commonly used in a close protection role for air-to-surface Imperial Guard deployments for regiments such as the Drop Troops of Elysia, the Vulture is also assigned to strafing missions against massed infantry formations and lightly-armoured vehicles. This is a complete resin and plastic kit, includes plastic flying base and plastic Hellstrike missiles and Rocket Pods. Punisher Cannons shown on some pictures sold separately.

Of course none of the easily found pictures on the web show the variant with the punisher cannons in action...
Or, if you are in to Chaos...and don't want to ally in some "trator guard" just go with three Helldrakes. Nothing says "can't Jink this" like three S6AP3 templates...
Just trying to help...
