From the six new green laser pointer weapon systems demonstrated by Russia, it is not difficult to see that Russia adheres to the development principle of “asymmetric” weapon systems, focuses on technological breakthroughs, and wins by quality; it follows “improving offensive forces, developing defensive forces, and strengthening strategic containment. The overall construction thinking, focusing on both offense…

The ballistic flight mode is converted into a cruise missile-like flight mode, that is, the warhead is inertially flying outside the atmosphere after being boosted to a height of more than tens of kilometers, and then re-enters the atmosphere to rely on aerodynamic lift for unpowered long-distance jumping and gliding maneuvers Or a ram engine…

In December 2017, the UK Ministry of Environmental Protection announced a new plan to complete the scan of the entire country by 2020. The current progress is 75%. The new plan will cover mountain and forest areas that have not been fully scanned before, and the accuracy will be increased to 1 meter. The UK…
