乖乖

而且還是之前於2017年5月24日駛入南沙美季礁6海浬內的USS Dewey (DDG-105)號所發射的~
這下支那慘了





美國在環太軍演成功測試岸艦飛彈HIMARS

美國再度成功測試電磁炮

 這次於USS Dewey (DDG-105)號發射超高速砲彈(Hyper Velocity Railgun)

重點在於美軍之後,可以在南沙群礁或是南海裡,直接發射超高速砲彈攻擊的說~

這下那些支那人工礁要慘了的說~

呵~

 超高速砲彈(Hyper Velocity Railgun) 的幾個優勢

1. 不用改砲管,直接裝上砲彈之後,就可以發射~ 像上次在環太軍演的USS Dewey (DDG-105)號,就是40年砲齡的MK-455砲管發射的~ 所以理論上所有DDG驅逐艦都可以發射這款新砲彈~

2. USS Dewey (DDG-105)號在去年環太軍演所發射的新砲彈,一次可以連續每分鐘發射15發~

3. 新砲彈可說是取代標-2導彈,一枚超高速HVR砲彈只要8萬5美金,但是一枚標-2導彈卻要100萬美金,所以大幅節省攻擊成本~

4. 新砲彈速度可以達到7馬赫~ 可擊穿任何艦體~

5. 新砲彈裝上GPS系統,成本也僅增高至10萬美金,還是比一枚近百萬美金的標-2導彈便宜十倍~

6. 新砲彈可用在美國海軍5吋砲管、美國陸軍155-mm砲管,及未來實用化的電磁砲管~ 通用性非常大~

=========================================

美軍已經艦上測試成功,這下支那人造礁真的不妙了~ 呵呵~

The US Navy has reportedly fired new hypervelocity railgun rounds out of 40-year-old deck guns - here's why

RYAN PICKRELLJAN 9, 2019, 03.28 AM

A US Navy destroyer test-fired hypervelocity projectiles from its standard MK 45 5-inch deck gun during the Rim of the Pacific exercises last year, USNI News reported Tuesday.
The high-speed rounds, designed for railguns, can be fired faster and farther than traditional artillery rounds from naval deck guns and land artillery pieces without modification.
The cost of each hypervelocity round is only a fraction of the cost of the missiles the US uses to intercept incoming threats.
The US Navy has reportedly been firing hypervelocity projectiles meant for electromagnetic railguns out of the 40-year-old deck guns that come standard on cruisers and destroyers, in hopes of taking out hostile drones and cruise missiles for a lot less money.

During last year's Rim of the Pacific (RIMPAC) exercises, 20 hypervelocity projectiles were fired from a standard Mk 45 5-inch deck gun aboard the USS Dewey, USNI News reported Tuesday, citing officials familiar with the test.

USNI's Sam LaGrone described the unusual test as "wildly successful."
BAE Systems, a hypervelocity projectile manufacturer, describes the round as a "next-generation, common, low drag, guided projectile capable of executing multiple missions for a number of gun systems, such as the Navy 5-Inch; Navy, Marine Corps, and Army 155-mm systems; and future electromagnetic (EM) railguns."

The US Navy has invested hundreds of millions of dollars and more than a decade into the development of railgun technology, but while these efforts have stalled, largely due to problems and challenges fundamental to the technology, it seems the round might have real potential.

The hypervelocity projectiles can be fired from existing guns without barrel modification. The rounds fly faster and farther than traditional rounds, and they are relatively inexpensive.

While more expensive than initially promised, a hypervelocity projectile with an improved guidance system, a necessity in a GPS contested or denied environment, only costs around $100,000 at the most, Bryan Clark, a naval affairs expert with the Center for Strategic and Budgetary Assessments, told USNI News. The Navy reportedly estimates that the high-speed rounds ought to cost somewhere around $85,000.

The cost of a single hypervelocity projectile is a fraction of the cost of air defense missiles like the Evolved Seasparrow Missile, Standard Missile-2, and Rolling Airframe Missile, all of which cost more than one million dollars each.

With the standard deck guns, which rely on proven powder propellants rather than electromagnetic energy, the Navy achieves a high rate of fire for air defense. "You can get 15 rounds a minute for an air defense mission," Clark told USNI News.
"That adds significant missile defense capacity when you think that each of those might be replacing a ESSM or a RAM missile. They're a lot less expensive," he added. Furthermore, US warships can carry a lot more of the high-speed rounds than they can missile interceptors.

USNI News explains that the intercept of Houthi cruise missiles by the USS Mason in the Red Sea back in 2016 was a multi-million dollar engagement. The hypervelocity rounds could potentially cut costs drastically.

The hypervelocity projectile potentially offers the Navy, as well as other service branches, a mobile, cost-effective air defense capability.

"Any place that you can take a 155 (howitzer), any place that you can take your navy DDG (destroyer), you have got an inexpensive, flexible air and missile defense capability," Vincent Sabio, the Hypervelocity Projectile program manager at the Pentagon's Strategic Capabilities Office, said last January, according to a report by Breaking Defense.

 這超高速砲彈原本是使用在電磁軌道砲上的,但軌道砲研發並不順利,砲彈反而開發成功,

美軍把它放入傳統的5吋砲發射,速度約7.3馬赫,射程50英里,大約80.5公里(傳統砲彈射程13英里,速度2.2馬赫),超高速砲彈不具傳統砲彈之爆炸性,而是由動能擊毀目標,由射程及破壞力可知,此超高速砲彈不是屬於攻擊武器,而是為反制超音速反鑑飛彈飽和攻擊所使用,5吋砲口徑太小並不適合攻陸,戰斧飛彈比較適合,50英里射程太短,對付高空戰機仍力有未逮,標準2仍不可淘汰。

搭配MK45 5吋砲,每分鐘可射20發

關於砲彈速度 各家媒體報導差異很大 有說7.3馬赫 有說3馬赫

欄主所引用的資料 以及R004所引用的National Interest 都宣稱是7.3馬赫

實際上可能只有3馬赫

若真是只有3馬赫 則應該還稱不上是"Hypervelocity"

儘管如此 由於射程暴增數倍 加上有導航功能 戰力因此大幅提升

不僅可以用來料理空中來襲目標 也可以用來料理海面上的敵方艦艇

基本上 這種新式炮彈可與傳統飛彈搭配互補

但絕對無法取代傳統飛彈的威力與精準度,以及低飛或匿蹤、人工智慧 等功能

==========

至於中國官媒幾天前放出關於中國艦載磁軌砲的新聞

基本上 是應對中國這一年多來接連在經貿與軍事(南海)上挨揍軟趴且又無力回手
幫習政權自慰壯膽兼維穩用的新聞

實際上 是笑話一則

就算再過個十年二十年 中國所謂的磁軌砲 還是只能停留在嘴砲與圈錢的階段 沒有任何軍用價值

================

再過幾個禮拜 本年度最具震撼性的太空新聞之一 即將出爐

SpaceX Starship Hopper的測試

Starship這個龐然大物在現階段的主要商業價值有三:
超低成本發射部署巨量衛星組成星座
超低成本組建新一代的巨型太空站
軍事用途

這種垂直降落的太空飛機 要轉用於類似現今大氣層內民航機的太空民航用途 可能性應該很有限

所以 SpaceX Starship 比較可能會是未來美國太空轟炸機(或者 太空堡壘)的原型

而不是通用型太空民航機的原型 (老人小孩通通都能搭)

Starship也會是SpaceX躋身全球軍火大廠之列的開端產品

================

有了長期在地球軌道上巡邏的太空轟炸機乃至太空堡壘 (還可以匿蹤 就像以前美國開發的隱形衛星)

以及數千上萬枚在低中高軌上對地面各角落進行監控的衛星 (全天24小時傳輸全球各地高解度的即時攝影畫面
也就是全年全天對地球表面的完全錄影)

在這階段 想要一次性大量料理掉中國境內的指揮中心 飛彈基地 空中飛行的軍機 海面航行的艦艇 等等

就會演進到"秒殺"的層次

這才是讓中國嚇尿破膽哀嚎求饒的絕命殺招

 磁軌砲在材料技術還未得到足夠突破之前
美英兩國可能會將這項武器研發以某種程度"封存"起來
頂多保留最低限度預算與研發人力來讓這項研究"保溫"
就像過去美國研發出來但後來被取消掉的航空百萬瓦級化學雷射炮 波音YAL-1
NASA太空梭也可算是另一個案例 雖有進入相當多年的實用階段 但最後還是因為成本高得離譜而整個被取消掉

磁軌砲的研發要能再大幅度"復活"起來
除了等待相關材料技術的突破之外
另一項取徑 則是先發展為太空武器 然後再慢慢突破進化到能部署於地表的磁軌砲

想要發展出實用的太空磁軌砲
又得等待SpaceX或Blue Origin的可回收式超重型火箭
尤其是SpaceX目前高速研發中的Starship

所以 歸根究柢
一切都得看SpaceX這家公司後續如何演進下去
或者說 Elon Musk這個自詡鋼鐵人的洋痞子 如何將美國國力推升到更加獨霸的層次
