Heavy bombers are large military aircraft designed to carry and deliver significant payloads of bombs over long distances. They are typically used in strategic bombing missions to target enemy infrastructure, military installations, and other critical assets. Heavy bombers can operate at high altitudes and are equipped with advanced navigation and targeting systems. These aircraft often have a long range and can be refueled in-flight, allowing them to reach distant targets without needing to land. Notable examples of heavy bombers include the Boeing B-17 Flying Fortress and the Northrop Grumman B-2 Spirit. Their ability to carry large bomb loads makes them essential in modern warfare.
