Which of the following systems is vulnerable to jamming?

The Standard Missile Guidance System is indeed vulnerable to jamming primarily because it relies on radar and other electronic signals for its guidance and targeting functions. Jamming can interfere with the radar signals used for guidance, which can prevent the missile from effectively tracking and engaging its target. This makes such systems particularly susceptible in environments where adversaries deploy electronic warfare tactics to disrupt or mislead missile guidance.

In contrast, the Harpoon, RAM, and Tomahawk Guidance Systems incorporate additional measures or alternative techniques that enhance their resilience against jamming. For example, the Harpoon typically uses a combination of radar and inertial guidance, and although it can also be jammed, it may have different resistance characteristics compared to the Standard Missile. The RAM and Tomahawk systems utilize advanced guidance technologies that are designed to mitigate the risks posed by jamming.

Understanding the vulnerabilities of these systems is crucial for developing countermeasures and ensuring effective military operations in the face of adversary electronic warfare efforts.
