The HAVw A5 Juggernaut was an Expanded Universe wheeled vehicle that appears in the Essential Guide to Vehicles and Vessels, and presumably one of the books or games that I don't recall. It actually began its life as a production sketch for one of the original films (iirc, a design for the Empire's war machines on Hoth, a role that ended up going to the AT-AT) at which time it didn't even have a name.
Fast forward around 3 decades, and ILM included a shot of the Juggernaut (presumably working off of the original production sketch) in one of the prequel films (I forget if it was AOTC or ROTS), thus officially making it (or at least its design) canon.
Have any other expanded universe vehicles (whether planet-based craft or spacecraft) appeared in the films and become canon? (This question partially addresses my question but doesn't even mention the Juggernaut)
