Which component gives the JDAM its capability to maneuver in flight?

The ability of the JDAM (Joint Direct Attack Munition) to maneuver in flight is primarily due to its aerosurfaces, also known as strakes. These are aerodynamic surfaces that are attached to the munition and enable it to change its flight path by altering its aerodynamic characteristics. When the JDAM is released from the aircraft, the strakes create lift and allow for controlled movement toward the target. This control is facilitated through adjustments in the girders that are integrated into the design of the JDAM, providing it with precision guidance and enabling it to hit targets accurately from extended ranges.

While the Guidance Control Unit plays a crucial role in processing data and controlling the JDAM's flight path based on navigation inputs, it is the aerosurfaces that physically provide the maneuverability. Other components, such as the TAS (Terminal Attack Sight) or the umbilical connector, serve distinct functions but do not contribute directly to the maneuverability of the JDAM during its descent. The correct choice focuses on the physical elements that actually influence the dynamics of its flight.
