Trident Warhead Now Deadlier Than Ever

Experts at the Bulletin of Atomic Scientists (The Bulletin) recently blew the lid off what the US government has euphemistically called it's “Life Extension Program” for the W76 thermonuclear warhead deployed on the Trident II D5 submarine-launched ballistic missile.

The article, “How US nuclear force modernization is undermining strategic stability: The burst-height compensating super-fuze,” authored by Hans M. Kristensen, Matthew McKinzie, and Theodore A. Postol, shows how the US military, under the guise of what it calls a “life-extension program” – allegedly intended to increase safety and reliability of nuclear warheads – has vastly increased the ability of warheads to detonate closer to their intended targets.

The heart of the rebuilt W76 and its increased kill capacity is the new MC4700 arming, fuzing and firing system. This new system essentially gives the W76 capabilities it never had before; that is the capability to hit hardened targets – specifically Russian ICBM silos – with three times greater accuracy than before.

The first MC4700 "super-fuzes" were completed in 2007 at the National Nuclear Security Administration's Kansas City  facility that is responsible for manufacturing and procuring nonnuclear components for U.S. nuclear weapons
The authors (in addition to detailed technical descriptions) explain this new capability in clear lay terms: “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.”

Steven Starr, a senior scientist at Physicians for Social Responsibility and an expert on the climatic consequences of nuclear war, called the report “the most frightening article I have ever read in the Bulletin of the Atomic Scientists.” Starr has good reason for concern, as should we. This article exposes the US government's continuing pursuit of nuclear dominance over Russia.

The following sentence summarizes that concern, which is centered on the Trident nuclear weapon system: “A decade ago, only about 20 percent of US submarine warheads had hard-target kill capability; today they all do.” This statement refers to the fact that the 100 kiloton W76 warhead previously did not have the capability, due to its relative lack of accuracy, of getting close enough to destroy “hard” targets such as Russian ICBM silos. ”

Because of the new super-fuze, essentially 100 percent of the warheads currently deployed on D5 missiles now have this capability to hit hard targets. This capability was previously reserved for the Minuteman III ICBMs and the relatively small number of W88 (455 kiloton) warheads also used on the D5 missile.

The implications of the development of the super-fuze and its use on the W76 are existential! Whatever the intentions of Pentagon planners, this development is most certainly sending a message to Russia that the US is building a significant first strike capability. As the article says, “by shifting the capability to submarines that can move to missile launch positions much closer to their targets than land-based missiles [and with the addition of the new super-fuze], the US military has achieved a significantly greater capacity to conduct a surprise first strike against Russian ICBM silos.”

And this would be only the opening salvo of a first strike attack. The remaining 80 percent of US ballistic missile warheads would likely be used to destroy mobile missile launchers, hardened command centers and other military and (potentially) civilian targets.

Since the Fall of the Berlin Wall, the OHIO Class “Trident” ballistic missile submarines have become the central, and most important, element in the US nuclear triad. Based on the New START treaty signed in 2010, roughly 70-percent of the U.S.’ nuclear warheads will be deployed on Trident submarines. Trident has the ability to move undetected while on its deterrent patrols, and can be stationed in strategic locations in the North Atlantic where its missiles would have a very short flight time to Russian targets.

The D5 missile can carry up to eight warheads. Under New START, the D5s carry an average of only four to five warheads. If New Start were to fail, which is becoming an increasing possibility with the current deterioration in relations between the US and Russia, the US could choose to fully load the D5s. In that case, based on the estimates in the article, two fully loaded Tridents (with 192 warheads each) could easily destroy all of the 136 Russian silo-based ICBMs.

The Russians have most certainly been keeping a close eye on US nuclear weapons developments. They have also been closely watching the US military's fascination with ballistic missile defense, which the Pentagon touts as purely “defensive,” but which Russia rightly perceives as the US seeking nuclear dominance. The article says: “The Russians have most recently reacted to this ongoing program by publicly displaying and implementing a new and novel sea-based nuclear weapons delivery device [an underwater drone] as a hedge against US missile defenses.”

Aside from the other current US nuclear weapons developments, the development of the W76 warhead super-fuze will likely be perceived by Russia as the most threatening. This is in large part due to Russia having no satellite early warning system, and relying instead on ground-based radars. Because they are far less sophisticated than US radar systems, the Russians have “less than half as much early-warning time” (15 minutes or less) in the event of a suspected US nuclear attack.

As the authors state, “The combination of this lack of Russian situational awareness, dangerously short warning times, high-readiness alert postures, and the increasing US strike capacity has created a deeply destabilizing and dangerous strategic nuclear situation. When viewed in the alarming context of deteriorating political relations between Russia and the West, and the threats and counter-threats that are now becoming the norm for both sides in this evolving standoff, it may well be that the danger of an accident leading to nuclear war is as high now as it was in periods of peak crisis during the Cold War.”

Both human and mechanical errors are inevitable in any system, and with nuclear weapons there is no margin for error. Accidents have occurred throughout the nuclear age, and more than one has involved false radar warnings. In 1995 a Russian early warning radar system mistakenly identified a scientific rocket launch from Norway as a submarine-launched (Trident) missile. Only at the last minute did officials realize that they were not under attack.

The end of the Cold War brought with it a historic opportunity for the US to begin serious negotiations with Russia leading to nuclear disarmament. Instead, our nation continued to pursue nuclear dominance, and as a result, over 25 years later we are entering into what is unarguably a new Cold War with Russia.

Trident is now three times more deadly than ever before. The US is rapidly moving toward production of a new ballistic missile submarine fleet that will be even more sophisticated than its predecessor. The twelve submarines of the Columbia Class (that will replace the OHIO Class) are being built to sail well into the end of this century. Along with the new submarines, the Navy is already seeking a new missile to replace the Trident II D5.

How long can we go building newer and more sophisticated (and deadly) nuclear weapon systems before they end up being used either accidentally or intentionally? How long can we play this dangerous game of nuclear brinksmanship before something snaps? How can our nations' leaders, in good conscience, continue to put humanity at risk of nuclear extinction?

The Bulletin article ends by quoting Russian President Putin speaking in 2016 about how he perceives (and how Russia will respond to) the West's offensive military posture. “No matter what we said to our American partners [to curb the production of weaponry], they refused to cooperate with us, they rejected our offers, and continue to do their own thing... I don't know how this is all going to end. What I do know is that we will need to defend ourselves.”

If the US is serious about reducing the risk of starting a nuclear holocaust, the President will have to begin repairing diplomatic relations with Russia. Meanwhile, a critical first step would be for President Trump to take all nuclear weapons, including submarine-launched ballistic missiles, off hair-trigger alert. This would demonstrate to the Russians that we have no intention of using our nuclear weapons in a pre-emptive, first strike, and would greatly reduce the risk of accidental launch of nuclear weapons and the resulting nuclear war.

The newly emerging nuclear arms race is a dangerous game that nobody can win; ultimately humanity will be the loser. The nuclear powers are addicted to the myth of nuclear deterrence and are driven to continue their insane pursuit of nuclear dominance. It is up to us as citizens to speak out in mass numbers calling on them to turn back from the brink and seek a path toward disarmament.

Trident: The Harsh Reality Beyond the Bright Lights in the Skies

If you live on the west coast of North America, stretching from Northern California to Mexico, you might have seen a wild light show on November 7th and November 9th. If you did, have no fear and definitely do not listen to any conspiracy theorists; there were no aliens involved. It was just two separate test launches of the Trident II D5 submarine launched ballistic missile.

But really; these are significant events! The US Navy launched the two test flights from the OHIO-Class "Trident" ballistic missile submarine (SSBN) USS Kentucky, which was submerged off of Point Mugu, Southern California. The missile traveled from its launch site to the US Ballistic Missile Test Site on Kwajalein Atoll in the Marshall Islands where it very likely plashed down in the precise location intended; it has been said that the multiple independently targetable reentry vehicles carried on the D5 missile can hit a target the size of a baseball diamond with extraordinary accuracy.

The Kentucky finished its mid-life overhaul and nuclear refueling in April 2015, and as part of its subsequent shakedown before being pressed back into service its crew conducted the test launches to ensure the proper functioning of its missile launch systems as well as the reliability of the Trident missile itself. The Kentucky is based at Naval Base Kitsap-Bangor, the Navy's West Coast home port for eight of the nation's fourteen Trident submarines.

Just one of these Trident submarines, each carrying up to 24 missiles, each missile currently carrying an estimated four warheads on independently targetable reentry vehicles, is capable of incinerating an entire large continent.

These two test launches marked the 156th and 157th successful test launches since the missile's initial deployment in 1990. The missiles are manufactured by Lockheed Martin Space Systems in Sunnyvale, California.

It is clear that, as Popular Mechanics stated it, the US is definitely "flexing its nuclear muscles" in a clear message to Russia that we've still got the nukes, and we're ready to use them. And Trident is king when it comes to US nukes; currently accounting for roughly 70% of deployed nuclear weapons in the US arsenal.

The Navy most likely timed the two Trident test launches with the intention of creating a public spectacle in order to ensure maximum visibility to other nations, particularly Russia. Ironically, the Russians have been keeping tabs on Trident (and other US nuclear weapon systems for some time since the fall of the Berlin Wall).

Had the US decreased reliance on Trident, a relic of the Cold War standoff between the US and then Soviet Union, following the end of the Cold War, things might now look much different on the global nuclear front. China has been building up a ballistic missile submarine fleet and the associated weapons. And of course, Russia has started building new SSBNs and is upgrading older SSBNs, and is developing a new submarine-launched ballistic missile (the Bulava).

A new Cold War is rapidly growing and heating up. Both the US and Russia have been throwing salvos of nuclear rhetoric at each other, and at this rate it might not be long before it starts looking much like it did back in the day when the two superpowers were locked in the deadly game of Mutually Assured Destruction. Dark days indeed!


The irony of all this is that we were handed an extraordinary "peace dividend" with the fall of the Berlin Wall. Had the US ramped back its nuclear weapons deployments back then, taking both land-based missiles and the Trident submarines off alert status, it would have sent a clear message that there was no need to threaten each other with extinction anymore.

Yet, in the case of Trident, the US had invested in a new missile, the Trident II D5, which was first deployed in 1990, just prior to the end of the Cold War. Neither the Navy nor Lockheed Martin were keen to mothball the new missiles or the crown jewel of the nation's nuclear triad (the Trident submarine). So Trident quietly continued to deploy, running silent and deep, essentially unnoticed here at home (although not by the Russians nor other nations).

And now the US Navy is hard at work, along with its partners in the shipbuilding sector, to develop a successor to the OHIO-Class (New Trident), scheduled to begin construction in 2021 and begin entering service in 2031.

The principal rationale given for the new submarines is the need to maintain the nation's "strategic nuclear deterrent." The principal irony of all this is that nuclear deterrence has failed a number of times (e.g. Cuban Missile Crisis), and it has only been by the miracle of human intervention that the world was saved from what would have certainly been the end of civilization (as we know it).

While "experts" have argued for the strategic deterrence doctrine during the strange days of the Cold War, we now live in an even stranger new world in which we have very unstable non-state actors (that might acquire a nuclear weapon) as well as states that quite possibly do not stand the test of "stability" required for deterrence to work.

Add to that the fact the probability that  leaders of stable nation states might act irrationally under times of great duress, and the argument for deterrence crumbles. Deterrence must be 100% infallible in order to be relied upon, and that is absolutely impossible in the real world. One failure could literally bring about the deaths of billions of people.

Trident was designed at the height of the Cold War, with at least one specific purpose - to present a guaranteed second strike capability (the ability to respond to a nuclear attack) to hold the Soviet Union at bay. The design of the Trident missile also presented an unstated purpose - to present a first strike (preemptive surprise attack) capability as well. Trident was only designed to hold the Soviet Union hostage to the inevitability of Mutually Assured Destruction, in which both nations would have waged full-scale nuclear war, obliterating each other's nations, murdering each other's populations, and resulting in "nuclear darkness," which would have resulted in the subsequent deaths by starvation of much of the rest of the world's population.

US Defense Secretary Ash Carter has recently been fanning the flames by accusing "Russia of endangering world order, citing its incursions in Ukraine and loose talk about nuclear weapons." In the article in The Economic Times Carter was also quoted as saying that, "Most disturbing, Moscow's nuclear saber-rattling raises questions about Russian leaders' commitment to strategic stability, their respect for norms against the use of nuclear weapons, and whether they respect the profound caution nuclear-age leaders showed with regard to the brandishing of nuclear weapons." Carter also referred to China in his remarks, but saved the strong stuff for Russia.

Ash Carter; Lecturing the world, while missing the "plank in our own eye."
The Economic Times nailed it with this statement: "The backdrop to Carter's remarks is the reality that after more than two decades of dominating great-power relations, the United States is seeing Russia reassert itself and China expand its military influence beyond its own shores." Therein lies the rub; The Cold War never really ended for the US. We have, ever since the fall of the Wall, had only one purpose - to maintain global hegemony through our military power.

I guess the lessons of parenthood have been lost on our nation's "leaders" (and the Military-Industrial Complex that controls them) - we can have influence on others, yet we cannot control them (in the long run at least). And yet we continue to try to exert control through our military, and nuclear weapons are the ultimate form of control by the threat of their use. It is coming back to haunt us.

The quest for nuclear weapons, and particularly Trident, has been (as one of my colleagues has called it) a Faustian bargain. Indeed, it is a deal with the Devil, and one where we cannot come out ahead. Scrapping Trident must be at the forefront of any efforts to abolish nuclear weapons, and reducing deployments and taking its weapons off alert status would be a major first step in showing good faith (while not unilaterally giving up anything of substance).


Will we, before it is too late, see the folly of our ways, realizing that it is futile to continue trying to maintain an empire the likes of which even the British never could have imagined? Will we come to see the futility of holding on to the fantasy of nuclear deterrence? Will we come to grips with the fact that nuclear weapons offer no security, and will most certainly (as any expert in probability and statistics will gladly explain) lead to either accidental or intentional nuclear war, with horrific consequences to humankind?

If only President Obama would find the convictions he left behind in Prague and sit down with President Putin to begin the necessary dialogue to begin the process of ramping back tensions between our two nations and begin the most important process of leading the world toward disarmament. Would that not be the legacy for which future generations would honor him?

Gadzooks - "Vintage" Nukes on New Tridents!!!

The US Naval Institute has done just what one would expect such an organization to do - raise the alarm over the "vintage" nuclear missiles (Trident II D-5) that will be initially deployed on the Navy's replacement ballistic missile submarines.  The institute's concern is that sooner (and not later) the Navy will need a new missile, and NOW is the time to get to work on it.

The obvious question, which NO ONE seems to be asking, is of what value is the Trident nuclear weapons system (OHIO class submarines with their Trident submarine-launched ballistic missiles) in today's world.  The Cold War is long over and the Trident weapons system, which was designed specifically to render the (then) Soviet Union a radioactive wasteland, is a true relic of a bygone era.

Would we really launch massive thermonuclear weapons (Trident II D-5s) against North Korea or Iran, considering the fact that the resulting radioactive fallout would affect adjacent countries.  Have we forgotten that the effects of nuclear weapons, once detonated, are uncontrollable, and that there is no practical way to clean up such a mess???

The final paragraph in the USNI article is laughable and misleading (using the words "current experience:).  In the context of that coupled with the rest of the article one might think that the US nuclear weapons complex was that of a developing nation, and that the technological wizards in North Korea are "currently" whizzing past us.
“The North Koreans have more current experience building and testing nuclear weapons than we do,” Goure said. “They also have more current experience with designing ballistic missiles—from scratch—than we do.”
So long as the US stays fixated on the doctrine of nuclear deterrence, we remain locked in a deadly paradox.  So long as the US (and Russia) continue to re-invigorate their nuclear forces, the rest of the world (North Korea, Iran...) will follow.  The results will likely not by pretty.

At any rate, with 143 consecutive successful test flights of the Trident II D-5 missile (under operational conditions) since 1989 (a perfect record!!!), it's hard to think of it as any remotely resembling "vintage."

Note to USNI: THIS is what a "vintage" nuclear weapon looks like.
Read the article for yourself, and see what you think of the author's argument.

Navy’s Nukes Won’t Keep Pace With New Missile Subs

By Dave Majumdar, USNI [US Naval Institute] News, Tuesday, April 23, 2013,   http://news.usni.org/2013/04/23/navys-nukes-dont-keep-pace-with-new-missile-subs

When the U.S. Navy’s new SSBN (X) conducts its first patrol in 2031 it will be an entirely new vessel, but the boat will initially rely on life-extended 1990s vintage Trident II D5 submarine-launched ballistic missiles (SLBMs) to perform its nuclear deterrence mission. The Navy currently expects to keep the D5 in service into the 2040s, after which it may replace the long-serving weapon with a new missile.

Though the United States is upgrading existing missiles and taking steps to keep its existing warheads viable, there is no work being done to develop a new intercontinental ballistic missile (ICBM) or SLBM for the time being. The Navy is deferring equipping the new SSBN(X) with a new missile because of the sheer cost of developing and fielding such a system during fiscally lean times. But moreover, there is no immediate military need to do so because the Trident will remain viable for sometime to come. However, the U.S. Strategic Command is conducting an analysis of alternatives for the future.

But there are questions as to how viable the U.S. missile industrial base will be when the time comes to develop a new missile later this century. Russia, since the collapse of the Soviet Union, has faced numerous difficulties with developing new ICBMs and SLBMs. The Bulava SLBM, for example, had numerous problems, failing six of 13 launch attempts before 2009. However, after a difficult period of troubleshooting, the Bulava program now appears to be on track, with seven successful missile launches since October 2010.

“Why would we be any different if we don’t maintain the experience base in making these things?” asks Dan Goure, an analyst at the Lexington Institute. NASA, for example, is essentially starting over in developing manned space-flight capability to a certain extent because those skill sets have atrophied, Goure said. “We can hope—only hope—that the work being done for Trident and United Launch Alliance and the Evolved Expendable Launch Vehicle (EELV) and work being done for NASA will maintain enough of a cadre so that we can in fact design a new ICBM,” he said.

There is no question that America needs to invest in keeping its nuclear deterrent credible, said Peter Huessy, an expert on nuclear weapons at GeoStrategic Analysis. In his view, however, the missile industrial base is less of a concern than retaining the ability to develop an actual nuclear warhead, he said. Huessy and Barry Watts at the Center for Strategic and Budgetary Assessments say that programs like the EELV or refurbishment programs for existing missiles are probably sufficient to keep ICBM and SLBM design skills alive. Huessy said that there are many components on the U.S. Air Force Minuteman III, for example, that are being replaced—which requires many of the skills needed to design an entirely new weapon. “They have all sorts of ideas on how to build a Minuteman [replacement],” he said.

But while the United States continues to upgrade existing missiles, other nations continue to develop and field nuclear weapons and the launch vehicles to deliver them. Russia continues to modernize its arsenal with new Topol-M ICBMs, new Bulava SLBMs, and reportedly another new heavy ICBM that is under development. So too, is China modernizing its nuclear forces, Huessy said. “[Assistant Defense Secretary Madelyn Creeden, in her April 17 testimony before the Senate Armed Services Committee] also concluded China is building advanced solid fueled rockets, a new type 094 Jin-class submarine along with its new JL-2 missile,” he said.

But the real problem might be far more serious than whether the United States will be able to build a new ballistic missile. There are doubts as to whether the nation will be able to retain the talent to build a new nuclear weapon in the future. “We’re as a matter of policy leaning in the direction of exiting the nuclear business,” Watts said.

Watts said that he simply does not know if the United States still has the capability to develop a new weapon. Huessy said that while lots of lab testing has been done, the country has not built a nuclear weapon since about 1991. “We’re also losing that talent,” he said. “The number of people who have built nuclear weapons could fit in a phone booth.”

The leftover warheads from end of the Cold War were approaching limits of what could be achieved for yield, Watts said, and were only designed for a lifespan of about 10 years. Now the weapons are approaching an average age of about quarter of century.

Though the U.S. nuclear stockpile most likely works, at the end the day, without a full-scale test, it is not known if the weapons would actually detonate properly, Huessy said. Essentially, without testing, the United States is hoping computer models are robust enough to make sure the devices work. The labs look for deteriorated parts and replace those. Ultimately though, “We’re guessing that they work,” Huessy said.

The United States could resolves some of those issues by bringing forward low-level design programs for ballistic missiles, Goure said. For a ballistic-missile program, the military would have to consider whether the Minuteman and Trident could be replaced with a common weapon, he said. However, given the size restrictions on board a submarine, a naval weapon would have to be adapted for land-based use—otherwise, it simply would not work. ICBMs are much larger than the typical SLBM and would not fit into the 87-inch tubes of either the Ohio or SSBN(X) classes of submarines, Goure said.

As for maintaining the nuclear-weapons complex, U.S. policy would have to fundamentally change. Watts said that if the assumption is that nuclear weapons are “going away,” then investing in new designs is a waste. President Barack Obama’s administration adheres to a vision of a “global zero” for nuclear weapons, but has pledged to maintain a credible deterrent. However, as the nation’s ability to design and build such weapons atrophies, so does that deterrent—and as Watts points out, the number nuclear-weapon states is increasing rather than decreasing.

“The North Koreans have more current experience building and testing nuclear weapons than we do,” Goure said. “They also have more current experience with designing ballistic missiles—from scratch—than we do.”
