True or False: IR guided missiles do not produce emissions during targeting and tracking, which reduces aircrew warning times.

The statement that IR guided missiles do not produce emissions during targeting and tracking is true. Infrared (IR) guidance systems operate by detecting the heat emitted from their targets, which allows them to engage without emitting signals that could reveal their presence. This characteristic greatly enhances stealth and reduces the warning time for aircrew, as conventional radar systems often emit detectable signals during targeting.

The lack of emissions from IR systems means that enemy defenses are less likely to detect the missile until it is very close to the target. This provides a significant tactical advantage, allowing for surprise and increasing the likelihood of successful engagement.

The other answer choices reflect possibilities that either introduce complexity not inherent in the nature of IR missiles or suggest circumstances that do not align with the established capabilities of IR guidance technology, thus making the true assertion about emissions and warning times stand out clearly as accurate.
