Tetrarch Heavy Lander
The Tetrarch Heavy Lander is a class of Imperial Navy orbit-to-surface dropship that is not only more sensibly designed but is arguably even bigger then the already ECKS BAWKS HUEG Devourer Dropship. The Tetrarch unlike the Devourer is able and capable to land an entire company or even a regiment of Imperial troops. The Tetrarch Heavy Lander seems to resemble the Space Marine Landing Craft in terms of usage, in that it is a heavily armed, turreted and presumably heavily armored transport.
From the looks of things, it seems that the Tetrarch Heavy Lander is much more formidably armed then the Devourer Dropship, boastin several large and HUEG Titan size cannons of unknown origins and supported by several more smaller battle cannons. Truly this thing is a Emperor Battle Titan with wings and only the very largest of Battleships could hold a handful of these things.
These guys first appeared in the Tactica Imperialis and has been a footnote ever since.
