Which sensor is NOT considered a fixed-wing sensor?

The Helios sensor is not considered a fixed-wing sensor because it is primarily designed for use on unmanned aerial vehicles (UAVs), specifically multirole systems, and newer platforms that may not fall into the traditional category of fixed-wing aircraft. Helios focuses on advanced surveillance and reconnaissance capabilities, typically optimized for rotary-wing platforms and UAVs, which require different operational considerations compared to fixed-wing aircraft.

In contrast, ATFLIR, LITENING AT, and SNIPER XR are all established as fixed-wing sensors used extensively in military aviation. These sensors are integrated into various fighter aircraft and are designed for air-to-ground missions, providing targeting, reconnaissance, and intelligence capabilities specifically tailored for the fixed-wing environment. Their design and application align closely with the operational needs of traditional fighter jets and bombers, ensuring they are classified as fixed-wing sensors.
