Space Wolves rejoice as the rumors of a new Space Wolf Gunship are in, and this time they are verified. This flyer is a beast, similar to a Stormraven in armour and special rules.

The Stormfang Gunship has the look of half of a Caestus Assault Ram, and is on the cover of next week's White Dwarf. The previous rumors really list out its abilities well. It comes with a Helfrost Destructor, two twin-linked heavy bolters, two stormstrike missiles and ceramite plating, with power of the machine spirit.

Heavy bolter upgrades to skyhammer missile launcher or two twin linked multi-meltas
stormstrike missiles can be upgraded to a twin linked lascannon.
