The World’s Most Dangerous Nuclear Weapon Just Rolled Off the Assembly Line


With the creation of a new “mini-nuke” warhead, the US is making nuclear war all the more probable…

Last month, the National Nuclear Security Administration (formerly the Atomic Energy Commission) announced that the first of a new generation of strategic nuclear weapons had rolled off the assembly line at its Pantex nuclear weapons plant in the panhandle of Texas. That warhead, the W76-2, is designed to be fitted to a submarine-launched Trident missile, a weapon with a range of more than 7,500 miles. By September, an undisclosed number of warheads will be delivered to the Navy for deployment.

What makes this particular nuke new is the fact that it carries a far smaller destructive payload than the thermonuclear monsters the Trident has been hosting for decades – not the equivalent of about 100 kilotons of TNT as previously, but of five kilotons. According to Stephen Young of the Union of Concerned Scientists, the W76-2 will yield “only” about one-third of the devastating power of the weapon that the Enola Gay, an American B-29 bomber, dropped on Hiroshima on August 6, 1945. Yet that very shrinkage of the power to devastate is precisely what makes this nuclear weapon potentially the most dangerous ever manufactured. Fulfilling the Trump administration’s quest for nuclear-war-fighting “flexibility,” it isn’t designed as a deterrent against another country launching its nukes; it’s designed to be used.  This is the weapon that could make the previously “unthinkable” thinkable.

There have long been “low-yield” nuclear weapons in the arsenals of the nuclear powers, including ones on cruise missiles, “air-drop bombs” (carried by planes), and even nuclear artillery shells — weapons designated as “tactical” and intended to be used in the confines of a specific battlefield or in a regional theater of war. The vast majority of them were, however, eliminated in the nuclear arms reductions that followed the end of the Cold War, a scaling-down by both the United States and Russia that would be quietly greeted with relief by battlefield commanders, those actually responsible for the potential use of such ordnance who understood its self-destructive absurdity.

Ranking some weapons as “low-yield” based on their destructive energy always depended on a distinction that reality made meaningless (once damage from radioactivity and atmospheric fallout was taken into account along with the unlikelihood that only one such weapon would be used). In fact, the elimination of tactical nukes represented a hard-boiled confrontation with the iron law of escalation, another commander’s insight — that any use of such a weapon against a similarly armed adversary would likely ignite an inevitable chain of nuclear escalation whose end point was barely imaginable. One side was never going to take a hit without responding in kind, launching a process that could rapidly spiral toward an apocalyptic exchange. “Limited nuclear war,” in other words, was a fool’s fantasy and gradually came to be universally acknowledged as such. No longer, unfortunately.

Unlike tactical weapons, intercontinental strategic nukes were designed to directly target the far-off homeland of an enemy. Until now, their extreme destructive power (so many times greater than that inflicted on Hiroshima) made it impossible to imagine genuine scenarios for their use that would be practically, not to mention morally, acceptable. It was exactly to remove that practical inhibition — the moral one seemed not to count — that the Trump administration recently began the process of withdrawing from the Cold War-era Intermediate-Range Nuclear Forces Treaty, while rolling a new “limited” weapon off the assembly line and so altering the Trident system. With these acts, there can be little question that humanity is entering a perilous second nuclear age.

That peril lies in the way a 70-year-old inhibition that undoubtedly saved the planet is potentially being shelved in a new world of supposedly “usable” nukes. Of course, a weapon with one-third the destructive power of the bomb dropped on Hiroshima, where as many as 150,000 died, might kill 50,000 people in a similar attack before escalation even began. Of such nukes, former Secretary of State George Shultz, who was at President Ronald Reagan’s elbow when Cold War-ending arms control negotiations climaxed, said, “A nuclear weapon is a nuclear weapon. You use a small one, then you go to a bigger one. I think nuclear weapons are nuclear weapons and we need to draw the line there.”


Until now, it’s been an anomaly of the nuclear age that some of the fiercest critics of such weaponry were drawn from among the very people who created it. The emblem of that is the Bulletin of Atomic Scientists, a bimonthly journal founded after the bombings of Hiroshima and Nagasaki by veteran scientists from the Manhattan Project, which created the first nuclear weapons. (Today, that magazine’s sponsors include 14 Nobel Laureates.) Beginning in 1947, the Bulletin’s cover has functioned annually as a kind of nuclear alarm, featuring a so-called Doomsday Clock, its minute hand always approaching “midnight” (defined as the moment of nuclear catastrophe).

…Given a kind of power that humans once only imagined in the hands of the gods, key former Manhattan Project scientists, including Enrico Fermi, James Conant, and J. Robert Oppenheimer, firmly opposed the development of such a new weapon as a potential threat to the human species. The Super Bomb would be, in Conant’s word, “genocidal.” Following the lead of those scientists, members of the Atomic Energy Commission recommended — by a vote of three to two — against developing such a fusion weapon, but President Truman ordered it done anyway.

In 1952, as the first H-bomb test approached, still-concerned atomic scientists proposed that the test be indefinitely postponed to avert a catastrophic “super” competition with the Soviets. They suggested that an approach be made to Moscow to mutually limit thermonuclear development only to research on, not actual testing of, such weaponry, especially since none of this could truly be done in secret. A fusion bomb’s test explosion would be readily detectable by the other side, which could then proceed with its own testing program. The scientists urged Moscow and Washington to draw just the sort of arms control line that the two nations would indeed agree to many years later.

At the time, the United States had the initiative. An out-of-control arms race with the potential accumulation of thousands of such weapons on both sides had not yet really begun. In 1952, the United States numbered its atomic arsenal in the low hundreds; the Soviet Union in the dozens. (Even those numbers, of course, already offered a vision of an Armageddon-like global war.) President Truman considered the proposal to indefinitely postpone the test. It was then backed by figures like Vannevar Bush, who headed the Office of Scientific Research and Development, which had overseen the wartime Manhattan Protect. Scientists like him already grasped the lesson that would only slowly dawn on policymakers — that every advance in the atomic capability of one of the superpowers would inexorably lead the other to match it, ad infinitum. The title of the bestselling James Jones novel of that moment caught the feeling perfectly: From Here to Eternity.

In the last days of his presidency, however, Truman decided against such an indefinite postponement of the test — against, that is, a break in the nuke-accumulation momentum that might well have changed history. On November 1, 1952, the first H-bomb — “Mike” — was detonated on an island in the Pacific. It had 500 times more lethal force than the bomb that obliterated Hiroshima. With a fireball more than three miles wide, not only did it destroy the three-story structure built to house it but also the entire island of Elugelab, as well as parts of several nearby islands.

In this way, the thermonuclear age began and the assembly line at that same Pantex plant really started to purr.  Less than 10 years later, the United States had 20,000 nukes, mostly H-bombs; Moscow, fewer than 2,000. And three months after that first test, theBulletin of the Atomic Scientists moved that hand on its still new clock to two minutes before midnight.
