Which sensor is a radio frequency (RF) radar ranging system used with the SUU-64/B, SUU-65/B, and SUU-66/B dispensers?

The FZU-39/B is a radio frequency (RF) radar ranging system specifically used with the SUU-64/B, SUU-65/B, and SUU-66/B dispensers. This system is designed to assist in accurately determining the distance to the target and supporting the effective delivery of munitions.

The choice of the FZU-39/B as the correct answer rests upon its development for the specific application of these dispensers, enhancing their operational effectiveness. It operates using RF technology, which allows for effective ranging and targeting, critical in munitions delivery.

In contrast, the other sensors mentioned, although they may have various applications, do not specifically align with the functionality required for the SUU-64/B, SUU-65/B, and SUU-66/B dispensers in the same capacity as the FZU-39/B. Each of these alternatives serves different roles or has different specifications that are not suited for the radar ranging needs of these specific dispensers.
