From the preview:
The Fire Raptor is a specialised variant of the Storm Eagle known to have its origins in the Imperium’s dim and distant past. The vehicle is configured to maximise ammunition stowage in order to feed the voracious appetite of its numerous weapons and this is achieved by sacrificing the Storm Eagle’s transport capacity.
Designed by Stuart Williamson, the Fire Raptor will be available as a pre-release at Games Day UK in limited quantities
