If you want to simulate war , not just flight, you need by Eagle Dynamics. While DCS is famous for its clickable F/A-18 and A-10 cockpits, the B-2 situation is more complex.
Because the B-2 lacks vertical stabilizers (the vertical fins on the tail of most planes), it cannot turn like a conventional aircraft. It uses a method called "differential drag." By opening a drag rudder on one wing, the aircraft creates more drag on that side, causing the nose to yaw in that direction. This results in a distinctive, smooth turning motion that flight simulators strive to replicate.
Before we look at the simulators themselves, it is crucial to understand why a B-2 bomber flight simulator is fundamentally different from an F-16 or Cessna 172 sim.
