Grizzly? That's a North American critter. Why can't Airbus name it for a European Critter? (Hmm, Destrier? Percheron? Big, strong horses that carry a lot of war kit ... )
Or how about a European superhero, like Perseus? Or Bellerophon? (OK, there was HMS Bellerophon, him what flew Pegasus ... but it has too many syllables for Air Force types ...
)
EDIT: oops, just realized the French would veto
Bellerophon, as Bonaparte surrendered himself to the Captain ...
Since the C-130 is the Herc, why not name the A400M Megara?
Atlas ... Ok, name it after some mountains on another continent, that'll work!
