quote [ A high-energy laser (HEL) fired from a US warship off the California coast has ignited a nearby boat. ]
The US Navy has fired a laser gun from one of its ships for the first time. Hurray for lasers ... is there anything they can't do (lasers that is, not the US Navy)?
Researchers mounted the Maritime Laser Demonstrator, a solid-state laser, aboard the USS Paul Foster, a decommissioned destroyer. Off the central California coast near San Nicholas Island on Wednesday, the laser fired a 15-kilowatt beam at an inflatable motorboat a mile away as both ships moved through the sea.

Well... I think 90+% are police. If not, try to get noise abatement legislation in place and then use binoculars and report the tail number to a local FAA office and file a complaint. In SW US, they're pretty good about following up. I'm talking US only. I have no idea about how that works elsewhere. |

Is there anything the the US Navy can't do? Survive a theoretical naval battle with a force of small but numerous vessels using low-tech or suicidal techniques? |

To be fair, theoretical battles aren't useful unless you sometimes lose. |

To be fair, they didn't technically lose, they reset the simulation and didn't let them use the tactic the second time. I really hope that works in real life. |

hey, if creatively interpreting the results or resetting the test to alter the outcome works to dissuade anyone from attacking the navy in such a way, then that in itself is an effective military tactic. the battle is won before it is ever fought, as that one chinese dude said. |

I kinda meant the reset part. I wasn't really hoping that the US navy could be sunk by a small fleet of suicide bombers, but in this day and age, maybe I should clarify that so I don't end up on a list. |

I am just wondering... if this sort of technology ever finds wide use against pirate vessels like the ones currently threatening sea travel around Somalia, wouldn't large mirrors suddenly become a valued commodity aboard such pirate vessels? |

I'm pretty sure weaponized lasers would cost a lot more to procure and maintain than any cargo they'd be able to steal. |

mrklipp

Mirrors are of no real use against high powered lasers. The reflectivity of the surface is critical, because whatever you don't reflect is absorbed and the damage quickly starts to further reduce the reflectivity of the surface. Mirrors don't reflect enough of the energy to prevent damage, basically the reflective layer is vaporized too quickly to be of any use. |

the midi-chlorians jump in and stop it at a certain length. yoda explained all this in Revenge Of The Sith right after the part where he said "oh, and by the way: I just learned how to come back as a ghost. not sure why I bring it up at this point, but that's why we haven't heard from Qui Gon Jin since he got killed." |

Lightsabres were supposed to be some sort of energetic material (e.g. plasma) held in some sort of containment field. |

actually I'm pretty sure it's that George just wanted a device that allowed for the drama of sword fights, but looked techy enough to exist in a sci-fi setting. |

Both of these explanations are accurate. George wanted laser swords: In universe it is a U shaped beam of energy that is curved back on itself with a magnetic field in an energy efficient system that only suffers signifigant energy loss when something touches the blade. |

In the expanded universe they use more traditional swords. Or at least as traditional as a vibrating sword can be. I base this entirely on KotOR, because I'm not quite enough of a geek to have read the comics and paperbacks. |

Vibroblades are common in star wars, but vibro swords are not. Kotor is 3000 years in the past. |

said @ 2:22pm GMT on 12th Apr
There is no difference between a "vibroblade" and a "vibrosword" other than a few extra points of damage and the vibroblade receiving a smaller penalty from being wielded in the off-hand. It's just RPG stats bullshit. Like how a glass weapons somehow do three times the damage as steel ones in the Elder Scrolls games. A gladius and a claymore are both swords, regardless of the size difference. What I want to know is, does a vibrating sword cut any better? |

granitewitch
said @ 8:41pm GMT on 11th Apr
More precise aim, I would think. Wind won't affect a beam of light, and you wouldn't have to lead the target. Not sure how long the pulse lasts, but if it's less than a tenth of a second it could be devastatingly accurate over a fair distance. |

With the railgun and lasers mounted to an all-electric nuclear-powered battleship, the potential for a catastrophic magazine explosion is eliminated, since the magazine entirely consists of milled steel darts, and the potential risk of catastrophic engine explosion is also reduced since it is impressively hard to make an ordinary nuclear reactor go boom. Using the lasers for missile defence makes out-ranging a railgun-equipped ship practically impossible, which means the enemy has to either catch up technologically or be prepared to take a railgun slug through the bridge/engine/magazine before they can get in range to fire their own main guns. |
