For underwater escape, the airbags raise the module to the surface after it has been severed from the plane. The aircraft's wings and much of the fuselage behind the crew module contain fuel tanks. External fuel tanks can be carried on the pylons under the wings and jettisoned if necessary. The F-111 can carry conventional as well as nuclear weapons. It can carry up to two bombs or additional fuel in the internal weapons bay.
External ordnance includes combinations of bombs, missiles and fuel tanks.
The loads nearest the fuselage on each side pivot as the wings sweep back, keeping ordnance parallel to the fuselage. Outer pylons do not move but can be jettisoned for high-speed flight. The avionics systems include communications, navigation, terrain following, target acquisition and attack, and suppression of enemy air defense systems. A radar bombing system is used for precise delivery of weapons on targets during night or bad weather. It allows the aircraft to fly in valleys and over mountains, day or night, regardless of weather conditions.
