The Convair F-102 Delta Dagger was developed during the Cold War as a response to the arms race with the Soviet Union. The goal was to create an aircraft capable of supersonic speeds that could intercept enemy bombers before they entered US airspace. However, technical challenges plagued its development.
The initial design overlooked basic aerodynamic principles, particularly the area rule principle, leading to modifications in the airframe and fuselage. Problems with propulsion, radar, and fire-control systems further complicated development.
The YF-102 prototype faced drag issues when approaching transonic speeds, preventing it from breaking the sound barrier initially. This forced engineers back to redesign parts of the aircraft. According to records from the National Museum of the USAF, extensive modifications were needed for success but introduced maintenance challenges.
