What characteristic differentiates guided weapons from unguided weapons?

The characteristic that differentiates guided weapons from unguided weapons is that guided weapons can be modified after launch. This capability allows guided weapons to adjust their flight path during their trajectory to accurately hit moving or stationary targets. This adjustment is typically achieved through various guidance systems, which may include GPS, laser guidance, or inertial navigation, enabling them to respond dynamically to changes in the target's position or environmental conditions.

In contrast, unguided weapons are designed for a one-way trajectory with no capability to adjust after launch. Once they are fired, they follow a predetermined path based on ballistic principles, meaning their effectiveness is largely determined by their initial aim and launch conditions. The complexity and cost associated with guidance systems do not apply to unguided weapons, although they may have simpler mechanisms and lower production costs.

The focus on target accuracy in guided weapons highlights the advancements in military technology, where precision strikes are crucial in modern warfare. This is particularly relevant in scenarios where collateral damage needs to be minimized or when engaging high-value or mobile targets.
