This angle of the aircraft shows us one of the prominent features of the BLK 50 Plus F-16C. All two-seat "Plus" aircraft have the enlarged avionics dorsal spine compartment which is located behind the cockpit and extends to the tail. It adds 30 cu ft (850 L) to the airframe for more avionics with only small increases in weight and drag.

Some BLK 50 plus aircraft can be fitted with CFTs (Conformal Fuel Tanks) which can carry an additional 3,000lbs of fuel.
