The B-58A is a high-altitude supersonic bomber manufactured by General Dynamics/Fort Worth, a Division of General Dynamics Corporation. The airplane is designed to carry externally attached weapons. The tactical mission is the destruction of surface objectives by bombs.
The flight crew consists of a pilot, a navigator, and a defensive systems operator. The navigator located at the second crew station performs the duties of navigator and operates the bombing equipment. The defensive systems operator at the third crew station operates the defensive ECM equipment and the remote controlled tail turret and performs the duties of a performance engineer.
The airplane fuselage is area-rule designed and for the greatest part is covered with a bonded, beaded skin. The wing is a full cantilever, midwing, modified delta design with a cambered leading edge and a bonded honeycomb skin. The three-man crew sits in tandem in separate compartments. Entrance to their positions is made through individual power actuated canopies. An air conditioning system maintains proper temperature, ventilation, and pressurization at all speeds and altitudes for crew compartments and temperature limited equipment. The crew is also provided with a liquid oxygen system. Electrical power for the airplane is supplied through a two-bus a-c distribution system by three ac generators which are driven by engines 1, 2, and 3 through constant speed drive units. A portion of the ac power is rectified to multiple voltages for d-c operated equipment; a 28-volt battery provides a limited source of dc power for operation during extreme emergencies. The tricycle landing gear, brakes, nose wheel steering, tail turret, autopilot servos, search radar, air refueling door, chaff dispenser drive, and flight control system are actuated by a dual hydraulic system. The flight control surfaces consist of two elevons and a rudder. The airplane is not equipped with flaps. The flight control system has provisions for automatic flight control throughout the flight mission (except for takeoff and landing). A pneumatic system provides for emergency operation of the landing gear and brakes. Normal actuation of the canopies, the drag chute, and the chaff dispensing system is accomplished by separate pneumatic systems. Offensive armament consists of bombing equipment. Defensive armament consists of defensive ECM equipment and a remote controlled tail turret equipped with a multi-barrel 20-mm cannon.
