It is very important to simulate the precision of fire of simple control Long Range Multiple Launch Rocket System ( LRMLRS) for improving the dispersion and reducing the number of rocket used in test. 简易控制远程多管火箭密集度仿真是提高射击密集度和减少简易制导多管火箭试验用弹量的重要手段。
So it doesn't take very long to catch up, in fact it's not even catching up, it's just seeing a new range of possibilities. 因此要赶上欧洲不需要太长时间,事实上也谈不上赶上,只是看到一系列新的可能性而已。
