[QUOTE="timewerx, post: 69243557, member: 314730"] They have already tested it onboard a Boeing 747. The effective range was something like 200 km -- on a clear day. The HUGE problem with lasers is when visibility is low, the range is dramatically reduced. Also, your target could easily hide behind a cloud and avoid your lasers. So effectiveness is dramatically reduced when clouds are present. Lasers could not cut a hole into clouds and it would be quite useless over major cities in China due to smog.... Even the best weapons-grade lasers currently in research could only be fired a limited number of times - given these current limitations, they are no better than conventional weaponry and even if clouds or visibility wasn't a problem, the only thing they can bring down are aircraft.... Lasers would still be largely ineffective if employed against tanks. Not to mention, it is rather quite easy to develop an effective defense against lasers. A highly reflective surface would deflect most of a laser's energy. Even if that is not sufficient, ablative paints could be developed to be applied to aircraft that ablates upon absorption of laser energy, carrying with it most of the damaging effects of the laser. I think the last weapons testing of such systems was back in early 2000..... Even Israel had their own laser program for defense against rockets. But instead, we saw that Israel ultimately came out with "conventional" CIWS using chemical explosives aimed and fired by a computer automatically to neutralize a threat such as RPGs I guess they also figured out my dilemma.... Of course, lasers would be more effective in space, there are no clouds, no smog, not even air.... But again, if your enemy figures out to apply ablative paint on their satellites, lasers would become pointless. [/QUOTE]
