Abstract:As a subversive force,airborne laser weapon is the focus of competition among countries,compared to the United States and the former Soviet Union used large transport aircraft for demonstration flight test platform,Israel used a Cessna 208B civilian aircraft in 2021.To promote the development of airborne laser weapon′s flight test technology,the development inductance,research status and planning,flight test characteristics of Israel has been studied,the results show that the pressure of rocket saturation attack is the realistic demand for the development of laser weapons,the flight test was the result of more than 30 years of continuous research on its laser weapon system,a fiber laser was used in this flight test,the weapon system weighs about 1.5 t,and all powered by storage batteries.This flight test mainly solved the closed loop verification problem,but there was lack of quantitative measurement and analysis of laser energy,continuous flight test is expected to follow.At the same time,the suggestions of selecting suitable testing platform and carrying out flight test of airborne laser weapon step by step are given。
