It's a mix of the Tornado and F-111 from what I've been told.
Here are the stats (I didn't come up with it so don't yell at me if they are wrong...):

In my opinion the best two strike aircraft of the 1970/80's good choice..... Excellent drawing. The Tornado's avionics package coupled with the Aardvarks weapons capability, unrivalled......
I would of added the Tornado's laser range finder under the forward fuselage, and lose the what i assume is a rotary bomb bay for a similar fuselage arrangement of pylons, add this to the Aardvarks 6 wing stations gives ability to carry jamming and decoy equipment external fuel and still an effective bomb load....
I didn't design the aircraft and I didn't draw the original drawing - I just gave it a North Point paint scheme.
Also, the point of the plane wasn't to minmax the capabilities but to create something believable within the time period imagined. I think Matt and Praetonia did a good job all things considered.
