Which type of guidance system is employed by the AGM-158 JASSM?

The AGM-158 Joint Air-to-Surface Standoff Missile (JASSM) primarily employs GPS guidance along with an advanced terminal guidance system that incorporates infrared imaging. This combination allows the missile to navigate accurately to its target while avoiding detection and countermeasures.

GPS guidance enables the JASSM to achieve high precision over long distances by using satellite signals to determine its location throughout the flight. The infrared imaging provides an enhanced capability for terminal guidance, allowing the missile to identify and home in on targets effectively in its final approach.

While other guidance systems are mentioned, such as laser, radar, and solely GPS, they do not encompass the full operational capabilities of the JASSM. The integration of GPS with infrared guidance gives the missile superior flexibility and effectiveness against various targets, particularly in contested environments where electronic countermeasures could interfere with other types of guidance.
