A supersonic bomber is a type of military aircraft designed to travel faster than the speed of sound, typically exceeding Mach 1. These bombers are capable of delivering a variety of munitions, including nuclear weapons, and are built for long-range missions. Their speed allows them to evade enemy defenses and reach targets quickly. One of the most famous examples of a supersonic bomber is the Tupolev Tu-160, developed by the Soviet Union. Another notable aircraft is the North American XB-70 Valkyrie, which was designed for high-altitude, high-speed missions during the Cold War.
