With the rapid development of detecting technology and guided weapons ,and the change of political and economic environment at home and abroad, the development direction of the future bombers have changed greatly. The long-range strategic bomber is always one important tool of the country’s strategic deterrence and long-range strike, and its own stealth performance and plan track strategic call more and more attention. In this paper, by comparing the stealth performance of next generation stealth bombers developed by the United States and Russia and their faced threats, higher performance requirements of the new generation of stealth bombers had been proposed―full spectrum, all directional stealth technology, such as radar stealth、infrared stealth and radio frequency stealth. High stealth strategic bomber penetration measures were also summarize, including more advanced stealth technology, system support, the high altitude penetration, equipped with self-defense weapons.
