variable-wing bomber

Variable-sweep wings, also known as swing wings, are a type of adjustable wing on an aircraft that can change their angle of sweep during flight. This feature is primarily used in military aircraft, allowing them to adapt their wing configuration for different flight conditions and missions.1

For example, the U.S. General Dynamics F-111, the first operational aircraft to feature variable-sweep wings, was designed to combine low-level bombing and high-altitude fighter capabilities. Other notable bombers utilizing this technology include the Soviet Tu-22 Backfire, the U.S. Rockwell International B-1, and the Tu-160 Blackjack. These aircraft use variable geometry to achieve high performance at low altitudes, often supplementing older subsonic designs and forming a significant part of nuclear forces.2
