Which components are included in the typical tail assembly of the JDAM?

The typical tail assembly of the Joint Direct Attack Munition (JDAM) indeed includes components essential for navigation and control during flight. The inclusion of a Global Positioning System (GPS) antenna is critical because it allows the JDAM to receive GPS signals for precise targeting, ensuring accuracy during its descent. Control fins are also part of the tail assembly, providing aerodynamic stability and steering capability to guide the munition to its intended target.

The other components listed in the alternative choices do not accurately represent what is included in the tail assembly of a JDAM. While propulsion systems and various guidance units are integral to the overall munition, they are not specifically part of the tail assembly. Instead, the tail assembly focuses on stabilization and guidance functions, which are crucial for the JDAM's effectiveness in striking targets accurately.
