The Spacer Union Nova airship 'Vega' (que up Holst's Mars, the Bringers of War now).
This is one of the big airships, coming in at 12 props, the Vega is capable of completely firebombing small cities and transports several units of elite SUN commandos. It can reach unmatched altitudes, perhaps 20,000 klicks, and speeds of up to 100 klicks an hour powered by coal and thaumaturgically enhanced engines. For a large picture of 2.5 by 1.75 feet, I did this one pretty quickly, in a bit over 3 hours. It is unfortunate that I can't show it in its full size, but you have to draw a line somewhere.
