美試射世界首個雷射武器 光速射擊比子彈更準
http://www.chinatimes.com/realtimenews/20170718002041-260417

美國最近在實彈試射中展現世界首個雷射武器系統擊毀無人機的實力,美軍官表示這個雷射武器用途相當廣泛、除了可廣泛攻擊各種目標外,其攻擊速度高達光速、也不易受到天氣影響。

這個被簡稱為LaWS的雷射系統已經上線、隨時可發射,目前架設在美國兩棲運輸船─龐塞號船塢平臺登陸艦(USS Ponce)上,CNN記者獲得獨家採訪權,見證其試射的情況。

海軍上將Christopher Wells說,這個雷射系統的精準度比子彈高,而且用途廣泛、不像某些武器只可用在空中目標,LaWs也可用於攻擊海面和地面目標等。

除此之外這個雷射武器有其他武器無法比擬的優勢,因為它可以光速攻擊,比洲際飛彈的速度快了5萬倍。負責其系統的上尉Cale Hughes說,這個武器等於是對迎來的物體投擲大量的光子,因此不會被風影響,也不用擔心射程等問題。

在試射中美國海軍模擬用雷射武器攻擊無人機,越來越多美國對手如伊朗、北韓、中國、俄羅斯等都逐漸採用無人機。Hughes說,這個雷射武器因為其高速,攻擊時不必預測目標無人機的走向並事先射擊,只要看到目標後瞄準即可。

雷射攻擊使得無人機的機翼立即起火,最後落入海中,雷射攻擊不會產生任何聲音和跡象,Hughes指出這是因雷射光位於電磁光譜中人眼無法辨識的波段,因此無聲無息、也驚人的有效率。

Wells說這使得美國海軍也不用擔心造成間接傷害,可以只攻擊目標的一點,不用擔心發生像子彈一樣、流彈可能飛到目標後方,不小心傷到或摧毀其他東西的問題。

這個造價4,000萬美元的雷射系統,因仰賴電力運作所以有自己的小型發電機,操作人員只有3人,這個系統不需要造價百萬的飛彈、也不須任何彈藥,每次射擊的成本只有1美元。

Hughes說這個系統主要是用來摧毀飛機或小型船隻、或是使之失去動力,過去3年以來這個系統已經證實它的效率。

儘管如此美國海軍已經在發展更強大的第二代系統,希望可攻擊更大的目標如迎來的飛彈等。這個第二代的消息屬於機密,但相關人士對其潛能深具信心,記者問Wells說目前的雷射系統是否可射下飛彈時,他僅回答「可能可以」並微微一笑。




Exclusive: CNN witnesses US Navy's drone-killing laser
http://edition.cnn.com/2017/07/17/politics/us-navy-drone-laser-weapon/index.html

CNN was granted exclusive access to a live-fire test of the laser.
"It is more precise than a bullet," Wells told CNN. "It's not a niche weapon system like some other weapons that we have throughout the military where it's only good against air contacts, or it's only good against surface targets, or it's only good against, you know, ground-based targets -- in this case this is a very versatile weapon, it can be used against a variety of targets."
LaWS begins with an advantage no other weapon ever invented comes even close to matching. It moves, by definition, at the speed of light. For comparison, that is 50,000 times the speed of an incoming ICBM.
"It is throwing massive amounts of photons at an incoming object," said Lt. Cale Hughes, laser weapons system officer. "We don't worry about wind, we don't worry about range, we don't worry about anything else. We're able to engage the targets at the speed of light."

CNN witnessed that speed and power firsthand.
For the test, the USS Ponce crew launched the target -- a drone aircraft, a weapon in increasing use by Iran, North Korea, China, Russia and other adversaries.
Immediately, the weapons team zeroed in. "We don't have to lead a target," Hughes explained. "We're doing that engagement at the speed of light so it really is a point and shoot -- we see it, we focus on it, and we can negate that target."
In an instant, the drone's wing lit up, heated to a temperature of thousands of degrees, lethally damaging the aircraft and sending it hurtling down to the sea.
The strike comes silently and invisibly. "It operates in an invisible part of the electromagnetic spectrum so you don't see the beam, it doesn't make any sound, it's completely silent and it's incredibly effective at what it does," said Hughes.
It is remarkably precise, which the Navy says could limit collateral damage in wartime.
"I can aim that at any particular spot on a target, and disable and destroy as necessary," said Wells. "It reduces collateral damage -- I no longer have to worry about rounds that may go beyond the target and potentially hurt or damage things that I don't want to hurt or damage."
All the $40 million system needs to operate is a supply of electricity, which is derived from its own small generator, and has a crew of three. No multi-million-dollar missile, no ammunition at all.
The cost per use? "It's about a dollar a shot," said Hughes.
Today, the laser is intended primarily to disable or destroy aircraft and small boats. "It's designed with the intent of being able to counter airborne and surface-based threats," said Hughes. "And it's been able to prove itself over the last three years as being incredibly effective at that."
However, the Navy is developing more powerful, second-generation systems which would bring more significant targets into its crosshairs: missiles.
Those missions remain classified. However, the commander and crew are very much aware of the potential capabilities. When we asked Wells if the current LaWS could shoot down a missile, he said simply "maybe" and smiled.

美壓縮導彈防禦預算 投資激光技術
https://orientaldaily.on.cc/cnt/china_world/20190314/00180_013.html

在北韓的導彈威脅仍未解除之際,美國導彈防禦局(MDA)周二宣布未來數年的預算將按年減至二○二二年的九十一億美元(約七百一十四億港元),而擴展陸基中段防禦系統的計劃則因技術問題要延遲兩年。

MDA公布新的預算案,顯示二○二○年的預算將減少十億美元至九十四億美元(約七百三十八億港元),預料翌年會減至九十二億美元(約七百二十二億港元)。五角大樓近年積極研發可攔截導彈的激光技術,預算由二○一八年的一億九百萬美元(約八億五千萬港元)大幅增至本年的二億二千四百萬美元(約十七億五千八百萬港元)。

北韓駐西班牙馬德里大使館於美朝河內峰會前夕,遭多名不明分子闖入偷走電腦及電話,期間綁起館內的工作人員。西班牙報章周三報道,部分涉事者與美國中情局有關,相信他們是搜集與負責美朝談判的北韓官員金赫哲有關的情報,但CIA否認涉事。
