While the missile is in flight, the variable incident wings move at a roll rate. What is the purpose of this roll rate?

• A. To stabilize at high altitude
• B. To speed up turning
• C. To keep the missile straight on its path to the target
• D. To adjust altitude

Answer: (C)

The main idea here is stability and keeping the missile on a straight, commanded path toward the target. The variable incident wings can change their angle of attack quickly as the missile rolls, creating a controlled roll moment that resists disturbances and keeps the aircraft’s lift vector aligned with the missile’s longitudinal axis. By adjusting the wing incidence with the roll, the system dampens unwanted yaw or lateral deviations and preserves a straight flight toward the target, which is why this roll rate is used to maintain that path. This isn’t primarily about speeding up a turn, nor about changing altitude as a first purpose, and while lift changes can affect altitude somewhat, the intended role of the wings’ roll response is to keep the missile from veering off its intended straight track to the target.
