What type of guidance combines two or more techniques into one missile?

The correct choice, hybrid guidance, refers to a missile guidance system that integrates two or more guidance techniques to enhance the effectiveness and performance of the missile. This approach allows the missile to leverage the strengths of various guidance methods, such as combining the precision of command guidance with the adaptability of homing guidance.

For instance, a hybrid system may utilize command guidance for initial trajectory corrections while also switching to homing guidance as it approaches the target, allowing it to accurately strike moving or evasive targets. This versatility significantly improves target acquisition and hits probability, especially in complex environments where threats may change rapidly.

The other guidance types mentioned have distinct characteristics. Command guidance relies on external control, usually from a ground or aerial operator, affecting the missile's flight path in real time without integrating other techniques. Homing guidance, on the other hand, utilizes onboard sensors to actively seek out the target, resulting in a fundamentally different operational methodology. Navigation guidance primarily focuses on waypoints and pre-programmed paths, which does not incorporate the adaptive nature that hybrid systems offer.
