A rocket bomb is a type of explosive missile that is propelled through the air by rockets. Synonyms for rocket bomb include ballistic missile, guided missile, cruise missile, surface-to-air missile, and surface-to-surface missile. These terms are used to describe a range of missiles that can be launched from the ground, air, or sea to carry out different types of attacks. Ballistic missiles are designed to travel in a parabolic trajectory, guided missiles have a guidance system that allows them to change direction in mid-flight, and cruise missiles are designed to fly at low altitudes and evade radar detection. Surface-to-air missiles are used to target aircraft, while surface-to-surface missiles are designed to attack land-based targets.
