美军将在军舰上部署激光炮
[font=Verdana, Arial, Tahoma][size=14px][b]美国海军打算2013年夏天首次在军舰上部署激光炮，并于2年之内对磁轨炮进行初步测试。这些未来范十足的装备颇有电影《星球大战》的风格。[/b][/size][/font][font=Verdana, Arial, Tahoma][size=14px][img=600,415]http://www.enread.com/upimg/allimg/140220/1_140220080810_1.jpg[/img]

[font=Verdana, Arial, Tahoma][size=14px]Some of the [url=http://www.enread.com/news/sciandtech/95693.html]Navy[/url]'s futuristic weapons sound like something out of "Star Wars," with lasers designed to shoot down aerial drones and electric guns that fire projectiles at hypersonic speeds.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]That future is now.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]The Navy plans to deploy its first laser on a ship later this year, and it intends to test an electromagnetic rail gun prototype aboard a vessel within two years.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]For the Navy, it's not so much about the whiz-bang technology as it is about the economics of such
[b]armaments（军备，武器）[/b]. Both costs pennies on the dollar compared with missiles and smart bombs, and the weapons can be fired continuously, unlike missiles and bombs, which eventually run out.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]"It fundamentally changes the way we fight," said Capt. Mike Ziv, program manager for directed energy and electric weapon systems for the Naval Sea Systems Command.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]The Navy's laser technology has evolved to the point that a prototype to be deployed aboard the USS Ponce this summer can be operated by a single sailor, he said.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]The solid-state Laser Weapon System is designed to target what the Navy describes as "asymmetrical threats." Those include aerial drones, speed boats and swarm boats, all potential threats to [url=http://www.enread.com/news/sciandtech/95693.html]warships[/url] in the Persian Gulf, where the Ponce, a floating staging base, is set to be deployed.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Rail guns, which have been tested on land in Virginia, fire a projectile at six or seven times the speed of sound -- enough velocity to cause severe damage. The Navy sees them as replacing or supplementing old-school guns, firing lethal[b] projectiles（落弹数）[/b] [/size][/font][font=Verdana, Arial, Tahoma][size=14px]from long distances.[/size][/font]
