The twin mainwheels of the undercarriage retract into the fuselage. The K2s, 3s and 4s all have wing refuelling points for fighters and a centerline refuelling capability to provide additional support for large aircraft. A long circular narrow-body fuselage with low swept wings set well back towards the tail, giving the appearance of having a very long forward fuselage. The pairs of podded engines are mounted on the sides of the rear fuselage below the swept 'T' tail unit. There is a large front port-side freight door.
Laser guided bombs are extremely accurate.
Paveway II was used to great effect during the Gulf war in 1991 and during the NATO air campaign against Bosnian Serb forces in 1995. Paveway III is a yet more sophisticated weapon which offers even greater accuracy and increased penetration power. The detector on the nose of the bomb locks on to laser energy reflected from the target. Paveway can be released in a slight climb or it can be released from straight and level flight. The weapon is aimed at the target and it initially follows a ballistic track.
