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.
