How US nuclear force modernization is undermining strategic stability: The burst-height compensating super-fuze | Bulletin of the Atomic Scientists

GR:  Nuclear war poses a massive threat to life on Earth. In fact, few analysts believe that anyone would survive a nuclear war. The security achieved by mutually assured destruction is madness. However, when madmen control governments nothing and everything is insane.

Members of the Bulletin of Atomic Scientists unveil the 2017 time for the “Doomsday Clock” January 26, 2017 in Washington, DC. For the first time in the 70-year history of the Doomsday Clock, the Bulletin of Atomic Scientists moved the clock forward 30 seconds to two and a half minutes before midnight, citing “ill-considered” statements by U.S. President Donald Trump on nuclear weapons and climate change, developments in Russia, North Korea, India and Pakistan.

“The US nuclear forces modernization program has been portrayed to the public as an effort to ensure the reliability and safety of warheads in the US nuclear arsenal, rather than to enhance their military capabilities. In reality, however, that program has implemented revolutionary new technologies that will vastly increase the targeting capability of the US ballistic missile arsenal. This increase in capability is astonishing—boosting the overall killing power of existing US ballistic missile forces by a factor of roughly three—and it creates exactly what one would expect to see, if a nuclear-armed state were planning to have the capacity to fight and win a nuclear war by disarming enemies with a surprise first strike.

“Because of improvements in the killing power of US submarine-launched ballistic missiles, those submarines now patrol with more than three times the number of warheads needed to destroy the entire fleet of Russian land-based missiles in their silos. US submarine-based missiles can carry multiple warheads, so hundreds of others, now in storage, could be added to the submarine-based missile force, making it all the more lethal.

“The revolutionary increase in the lethality of submarine-borne US nuclear forces comes from a “super-fuze” device that since 2009 has been incorporated into the Navy’s W76-1/Mk4A warhead as part of a decade-long life-extension program. We estimate that all warheads deployed on US ballistic missile submarines now have this fuzing capability. Because the innovations in the super-fuze appear, to the non-technical eye, to be minor, policymakers outside of the US government (and probably inside the government as well) have completely missed its revolutionary impact on military capabilities and its important implications for global security.

“Before the invention of this new fuzing mechanism, even the most accurate ballistic missile warheads might not detonate close enough to targets hardened against nuclear attack to destroy them. But the new super-fuze is designed to destroy fixed targets by detonating above and around a target in a much more effective way. Warheads that would otherwise overfly a target and land too far away will now, because of the new fuzing system, detonate above the target.

FIGURE 1. The deployment of the new MC4700 arming, fuzing, and firing system on the W76-1/Mk4A significantly increases the number of hard target kill-capable warheads on US ballistic missile submarines.

“The result of this fuzing scheme is a significant increase in the probability that a warhead will explode close enough to destroy the target even though the accuracy of the missile-warhead system has itself not improved.

“As a consequence, the US submarine force today is much more capable than it was previously against hardened targets such as Russian ICBM silos. A decade ago, only about 20 percent of US submarine warheads had hard-target kill capability; today they all do. (See Figure 1.)” Hans M. Kristensen, Matthew McKinzie, and Theodore A.

It is now two and a half minutes to midnight | Bulletin of the Atomic Scientists

GR:  A group of concerned scientists created the Doomsday Clock at the end of World War II. The goal was to use best estimates of global conditions to create a visual display of the nuclear danger. Now, however scientists consider climate change as well as nuclear war as the most pressing threats to our survival. In 2010, after the hopeful conclusion to the Copenhagen Climate-Change Conference, the Clock was at six minutes to midnight. However, nuclear developments in North Korea and continuing tension in southern Asia moved the Clock to five minutes until midnight in 2012. The nuclear situation has not improved and the climate situation is worse. Today the Clock is at two and one-half minutes until midnight.

I included a link to an informative slide show at the end of this post. The Clock has  moved closer to doomsday because of Donald Trump’s statements. Will Trump be pleased with his great accomplishment? I recommend this short press conference on the new clock setting:  http://clock.thebulletin.org.

DOOMSDAY CLOCK MOVES AHEAD:

“Words Matter”: The Board Marks 70th Anniversary of Iconic Clock By Expressing Concern About “Unsettling” and “Ill-Considered” Statements of President Trump on Nuclear Weapons and Climate Change; Developments in North Korea, Russia, India and Pakistan Also Highlighted.

WASHINGTON, D.C. – January 26, 2017 – “It is now two and a half minutes to midnight. For the first time in the 70-year history of the Doomsday Clock, the Bulletin of the Atomic Scientists’ Science and Security Board has moved the hands of the iconic clock 30 seconds closer to midnight. In another first, the Board has decided to act, in part, based on the words of a single person: Donald Trump, the new President of the United States.

“The decision to move the hands of the Doomsday Clock is made by the Science and Security Board of the Bulletin of the Atomic Scientists in consultation with the Bulletin’s Board of Sponsors, which includes 15 Nobel Laureates. The Science and Security Board’s full statement about the Clock is available online.

“In January 2016, the Doomsday Clock’s minute hand did not change, remaining at three minutes before midnight. The Clock was changed in 2015 from five to three minutes to midnight, the closest it had been since the arms race of the 1980s.

“In the statement about the Doomsday Clock, the Bulletin’s Science and Security Board notes: “Over the course of 2016, the global security landscape darkened as the international community failed to come effectively to grips with humanity’s most pressing existential threats, nuclear weapons and climate change … This already-threatening world situation was the backdrop for a rise in strident nationalism worldwide in 2016, including in a US presidential campaign during which the eventual victor, Donald Trump, made disturbing comments about the use and proliferation of nuclear weapons and expressed disbelief in the overwhelming scientific consensus on climate change …The board’s decision to move the clock less than a full minute — something it has never before done — reflects a simple reality: As this statement is issued, Donald Trump has been the US president only a matter of days …”

“The statement continues: “Just the same, words matter, and President Trump has had plenty to say over the last year. Both his statements and his actions as President-elect have broken with historical precedent in unsettling ways. He has made ill-considered comments about expanding the US nuclear arsenal. He has shown a troubling propensity to discount or outright reject expert advice related to international security, including the conclusions of intelligence experts. And his nominees to head the Energy Department, and the Environmental Protection Agency dispute the basics of climate science. In short, even though he has just now taken office, the president’s intemperate statements, lack of openness to expert advice, and questionable cabinet nominations have already made a bad international security situation worse.”

“In addition to addressing the statements made by President Trump, the Board also expressed concern about the greater global context of nuclear and climate issues:” –Janice Sinclaire (Continue reading:  It is now two and a half minutes to midnight | Bulletin of the Atomic Scientists).
