Which statement describes a Passive weapon guidance system?

• A. Directing Intelligence Is Received From The Target.
• B. Target Illumination Is Supplied By An External Transmitter.
• C. Missile Uses Internal Illumination For Guidance.
• D. Guidance Is Via GPS Only.

Answer: (A)

Passive guidance means the weapon does not emit its own signals to find the target; it relies on information supplied from an external source about the target. When directing intelligence is received from the target, the weapon can steer using that externally provided data rather than actively scanning or illuminating the target itself. This approach keeps the sensor from generating its own energy toward the target and instead follows the guidance information fed to it from elsewhere.

The other scenarios describe non-passive methods: target illumination from an external transmitter involves energy the weapon uses indirectly (semi-active guidance); the missile emitting its own energy to illuminate the target is active guidance; and relying solely on GPS provides navigation data rather than target-directed guidance from an external intelligence source.
