According to the movement character of carrier fighting group,this paper presents that the movement forecast model of carrier fighting group is built by the mean of combining the grey model with the self-regression time series AR.

Adopting the combination of quality and quantity analysis, this paper briefly describes the constitution of the US air-carrier fighting group air-attack system,then establishs the mathematic model of destroying effectiveness to ground targets of ammunition and cruise missile and analyses the effectiveness of air-attack firepower of US carrier fighting group at four sections.

Then analyses the effectiveness of air-raid firepower of US carrier battle group at four sections.

This paper introduces the composition of combat power and EW power in the carrier battle group of USA and the configuration in the antimissile and air defense systems,analyses the ability of EW from EW weapon equipments in carrier battle group on electronic reconnaissance,electronic attack and electronic counter-countermeasure.

The study of the aircraft carrier battle group (CVBG ) communication countermeasure system is a very important problem.

This paper introduces the main electronic targets and their performances of the aircraft carrier battle group,studies the means to perform the electronic attack to these targets.
