Medium bombers are military aircraft designed to carry out bombing missions at moderate ranges. They typically have a balance of payload capacity and speed, allowing them to deliver bombs effectively while maintaining a degree of maneuverability. These aircraft can target enemy installations, troop concentrations, and supply lines. Examples of medium bombers include the Boeing B-17 Flying Fortress and the Douglas A-26 Invader. They are equipped with various armaments and can often perform multiple roles, including reconnaissance and ground attack. Medium bombers played a significant role in conflicts such as World War II and continue to be relevant in modern military operations.
