雄三不孤單,三叉戟來伴

Comment
三叉戟與雄三,都是三?


此時吵出這新聞,明顯與關川普新時代有關。
根本沒事,同時段也正在測試SLBM三叉戟IID5。而且,亂飛的是測試版。
SLBM三叉戟IID5,是美國的(不知道發展時是否兩國共同?),總之UKSLBM,是美英共同資產,發射程序也是。

《星期日泰晤士報》說,英國海軍6月從佛羅里達海岸線以外的潛艇發射三叉戟IID5導彈,但是,導彈飛行方向發生偏差,本應飛往非洲,卻飛向了美國

7月,梅就任首相不久之後,英國國會高票通過決議重建三叉戟。當時梅首相告訴議會,英國放棄核武器是"極端不負責任" 的。

媒體爆料後,英國國防部發表聲明,雖然沒有透露試射程序詳情,但是說試射是成功的。

不過BBC國防事務記者喬納森·比爾注意到,國防部的聲明說試射對"潛艇""船員"(的檢測)是成功的,但並沒有否認導彈本身偏離方向了。

今天(22日),英國首相特雷莎·梅接受BBC早間新聞節目的訪問,其間主持人先後四次追問,她去年7月間說服國會通過決議、斥資400億英鎊重建三叉戟時是否知道試射失誤這件事。
不過,梅首相第一次沒有直接回答問題,而是說「我對三叉戟有絶對信心」,「當時我在國會演說時,我們討論的是不是要重建三叉戟。」
後三次主持人再問,梅首相干脆沒有回答問題。


The malfunction came just weeks before the House of Commons was asked on July 18 to approve the replacement of the ageing submarines that carry Britain's nuclear arsenal.  May was not prime minister at the time of the test, but she took office shortly before the vote and successfully appealed to lawmakers to approve the 41 billion (47 billion euro, USD 50.7 billion) project.
Britain is one of only three nuclear-armed NATO nations, along with the United States and France.

An authoritative report said an unarmed Trident II D5 missile had veered in the wrong direction towards the US coastline when it was launched from a British submarine, HMS Vengeance, off Florida, last June.

MPs voted last summer to spend around £40 billion on replacing Trident, having absorbed Mrs May’s assertion that she would be willing to authorise a nuclear strike that could mean the deaths of 100,000 people. 

The US Navy is test-firing and upgrading its arsenal of Trident II D5 nuclear-armed submarine launched missiles designed to keep international peace -- by ensuring and undersea-fired second-strike ability in the event of a catastrophic nuclear first strike on the US.

Firing from the Atlantic Ocean off the coast of Florida several months ago, a specially configured non-armed “test” version of the missile was fired from the Navy’s USS Maryland.  This was the 161st successful Trident II launch since design completion in 1989.

The Trident II D5 missile is deployed aboard U.S. Navy Ohio-class submarines and Royal Navy Vanguard-class to deter nuclear aggression. The three-stage ballistic missile can travel a nominal range of 4,000 nautical miles and carry multiple independently targeted reentry bodies.

The U.S. and UK are collaboratively working on a common missile compartment for their next generation SSBNs, or ballistic missile submarines.

"The Trident D5s carry three types of warheads: the 100-kiloton W76/Mk-4, the 100-kiloton W76-1/Mk-4A, and the 455-kiloton W88/Mk-5 warhead, the highest-yield ballistic missile warhead in the U.S. arsenal."

The Trident II D5, first fired in the 1990s, is an upgraded version of the 1970s-era Trident I nuclear weapon; the Trident II D5s were initially engineered to serve until 2027, however an ongoing series of upgrades are now working to extend its service life.

The missiles are also being planned as the baseline weapon for the Ohio Replacement Program ballistic missile submarine, a platform slated to serve well into the 2080s, so the Navy wants to extend the service life of the Trident II D5 missiles to ensure mission success in future decades.

Under the U.S.-Russia New START treaty signed in 2010, roughly 70-percent of the U.S.’ nuclear warheads will be deployed on submarines.
