Which characteristic is NOT typically a feature of ship defenses against air-to-surface weapons?

High-speed attack vessels are primarily designed for offensive operations, such as engaging enemy ships or conducting reconnaissance missions. While they can maneuver quickly and evade threats, they are not primarily a defense mechanism against air-to-surface weapons. Instead, ship defenses focus on systems tailored for protection, such as close-in weapons systems that provide a last line of defense against incoming threats, decoys and electronic counter-measures that confuse or mislead enemy targeting systems, and surface-to-air missiles that are explicitly designed to intercept and destroy airborne threats.

In contrast, high-speed attack vessels do not fall under the category of defensive features aimed at protecting a ship from aerial assaults, which makes them the correct choice in this context.
