Armageddon

There is a new arms race, based this time not on number of weapons but on increasing lethality, says William Potter, director of nonproliferation studies at the Middlebury Institute of International Studies in Monterey, California.

Obama rode into office in 2009 with promises to work toward a nuclear-free world. His vow helped win him the Nobel Peace Prize that year.

Obama transformed its main hydrogen bomb into a guided smart weapon. Until recently, the B61 was an old-fashioned gravity bomb, dropped by a plane and free-falling to its target. The Air Force has transformed it into a controllable smart bomb. The new model has adjustable tail fins and a guidance system which lets bomber crews direct it to its target. Recent models of the bomb had already incorporated a unique “dial-down capacity”: The Air Force can adjust the explosion. The bomb can be set to use against enemy troops, with a 0.3 kiloton detonation, a tiny fraction of the Hiroshima bomb, or it can level cities with a 340-kiloton blast with 23 times the force of Hiroshima’s. Similar controls are planned for new cruise missiles. The new B61 is the most expensive bomb ever built. At $20.8 million per bomb, each costs nearly one-third more than its weight in 24 karat gold. The estimated price of the planned total of 480 bombs is almost $10 billion.

Congress also has approved initial funding of $1.8 billion to build a completely new weapon, the “Long Range Stand-Off” cruise missile, at an estimated $17 billion total cost. The cruise missiles, too, will be launched from aircraft. But in contrast to stealth bombers dropping the new B61s directly over land, the cruise missiles will let bombers fly far out of range of enemy air defenses and fire the missiles deep into enemy territory.

Its submarine-launched nuclear missiles five times more accurate, and gave its land-based long-range missiles so many added features that the Air Force in 2012 described them as “basically new.” To deliver these more lethal weapons, military contractors are building fleets of new heavy bombers and submarines.

Trump has embraced Obama's modernization program enthusiastically. Trump has ordered the Defense Department to complete a review of the U.S. nuclear arsenal by the end of this year.

William Perry, who served as defense secretary under President Bill Clinton, said recently in a Q&A on YouTube that “the danger of a nuclear catastrophe today is greater than it was during the Cold War.”

Perry told Reuters that both the United States and Russia have upgraded their arsenals in ways that make the use of nuclear weapons likelier. The U.S. upgrade, he said, has occurred almost exclusively behind closed doors. “It is happening without any basic public discussion,” he said. “We’re just doing it.”

 Jon Wolfsthal, a former top advisor to Obama on arms control, said it is possible to have potentially devastating arms race even with a relatively small number of weapons.

In October the International Campaign to Abolish Nuclear Weapons, a Geneva organization, won the Nobel Peace Prize for its role in getting the United Nations General Assembly in July to adopt a nuclear prohibition treaty. The United States, Russia, and other nuclear powers boycotted the treaty negotiations.

The U.S. modernization effort is not coming cheap. This year the Congressional Budget Office estimated the program will cost at least $1.25 trillion over 30 years. The amount could grow significantly, as the Pentagon has a history of major cost overruns on large acquisition projects.

The New Strategic Arms Reduction Treaty, known as New START limited each side to what the treaty counts as 1,550 strategic nuclear warheads. both Moscow and Washington are on track to meet the 1,550 limit by the treaty’s 2018 deadline. The treaty, however, allows for fudging. Each bomber is counted as a single warhead, no matter how many nuclear bombs it carries or has ready for use. As a result, the real limit for each side is about 2,000.

Under New START, 14 of America’s Ohio Class subs carry 20 Tridents. Each Trident can be loaded with up to 12 warheads. (The United States has four additional Ohio subs that carry only conventional weapons.) The Trident II’s official range is 7,456 miles, nearly one-third the Earth’s circumference. Outside experts say the real range almost certainly is greater. Each of its main type of warhead produces a 475-kiloton blast, almost 32 times that of Hiroshima.

The New START treaty limits the number of warheads and launch vehicles. But it says nothing about the design of the “delivery” methods – land- and submarine-based ballistic missiles, hydrogen bombs and cruise missiles. Thus both sides are increasing exponentially the killing power of these weapons, upgrading the delivery vehicles so that they are bigger, more accurate and equipped with dangerous new features – without increasing the number of warheads or vehicles. The United States, according to the Bulletin of the Atomic Scientists, has roughly tripled the “killing power” of its existing ballistic missile force. The U.S. modernization program “has implemented revolutionary new technologies that will vastly increase the targeting capability of the U.S. ballistic missile arsenal. This increase in capability is astonishing.”

Russia is making its own extensive enhancements, including larger missiles and new launch vehicles. He said Russia also is devoting much effort to countering U.S. missile defense systems. Russia is building new ground-based missiles, including a super ICBM, the RS-28 Sarmat. The Russian missile has room for at least 10 warheads that can be aimed at separate targets. Russian state media has said that the missile could destroy areas as large as Texas or France. Russia’s new ICBMs have room to add additional warheads, in case the New START treaty expires or either side abrogates it. Russia has phased in a more accurate submarine-launched missile, the RSM-56 Bulava. While it is less precise than the new U.S. Tridents, it marks a significant improvement in reliability and accuracy over Russia’s previous sub-based missiles.

A Russian military official in 2015 disclosed a sort of doomsday weapon, taking the idea of a “dirty bomb”. The purported device is an unmanned submarine drone, able to cruise at a fast 56 knots and travel 6,200 miles. The concept of a dirty bomb, never used to date, is that terrorists would spread harmful radioactive material by detonating a conventional explosive such as dynamite. In the case of the Russian drone, a big amount of deadly radioactive material would be dispersed by a nuclear bomb. The bomb would be heavily “salted” with radioactive cobalt, which emits deadly gamma rays for years. The explosion and wind would spread the cobalt for hundreds of miles, making much of the U.S. East Coast uninhabitable. A documentary shown on Russian state TV said the drone is meant to create “areas of wide radioactive contamination that would be unsuitable for military, economic, or other activity for long periods of time.” Reif of the Arms Control Association says that even if the concept is only on the drawing board, the device represents “really outlandish thinking” by the Russian government. “It makes no sense strategically,” he said, “and reflects a really egregiously twisted conception about what’s necessary for nuclear deterrence.”
