What feature does an F-16 have to protect against a radar guided missile?

The correct answer is that the F-16 utilizes a countermeasure known as the AN-ALE-50, which is a towed decoy system specifically designed to protect the aircraft from radar-guided missiles. This system works by deploying a decoy that mimics the radar signature of the aircraft, diverting the attention of radar-guided missiles away from the F-16. By engaging the enemy's radar and providing a false target, the AN-ALE-50 increases the chances of survival in scenarios where the aircraft is under threat from radar-guided systems.

Other options relate to different countermeasure techniques used in electronic warfare or aircraft defense strategies. While options such as chaff and flares are widely recognized and used to counter different types of missiles (primarily infrared-guided missiles), they do not provide the specific protection against radar-guided threats that the AN-ALE-50 offers. The advanced radar system mentioned is crucial for situational awareness and targeting but does not directly serve the purpose of countermeasures against missile threats. Similarly, a countermeasure dispenser is a more general term and does not specifically denote the capabilities or functions offered by the AN-ALE-50.
