F-136 Orbital Defense
By William Ortis; Lionheart Creations
This is a superb shot of the top of the hull.  The fins have been set to minimum
deployment for extreme tactical manuvering while still at high speed flight.  

You can barely make out the 'spoilerons' which are flaps on the top of the hull.  
These raise up on one side at a time to stall that side of the ships lift, causing
the vehicle to bank on that side and direction.  The spoilerons are tuned to open
moderately when needed as can be seen on the tarmac.
