What does CMWS detect and respond to within its field of view?

The correct answer, missile threats, reflects the specific capability of the Countermeasure Warning System (CMWS). This system is designed to identify and respond to incoming threats, particularly from missiles, that could potentially target aircraft or other military assets. By detecting infrared signatures associated with missile launches, the CMWS can provide alerts and facilitate timely countermeasures to safeguard the platform it is protecting.

In contrast, other options such as ground threats, air traffic, and weather conditions pertain to different domains or systems. Ground threats generally relate to ground-based systems designed to detect enemy actions or vehicles, air traffic involves tracking civilian or other aircraft for navigation and safety, and weather conditions deal with environmental monitoring systems. Each of these areas requires different technologies and focuses, which helps reinforce why missile threats are the primary concern for CMWS.
