Trump Administration Rolls Out Low-Yield Nukes



"around 1/3 of the force of the bomb dropped on Hiroshima."

The United States has begun manufacturing a low-yield nuclear warhead to be used in Trident missiles, reports The Guardian citing an emailed announcement by the National Nuclear Security Administration (NNSA).


The new weapon - the W76-2, is a modification of an existing Trident nuclear warhead. According to the NNSA, the first batch have come off the production line, and an unspecified number of them referred to as "initial operational capability" will be ready for delivery before the end of September.

According to Stephen Young, a senior Washington representative of the Union of Concerned Scientists, the yield on the W76 was likely reduced to created the W76-2 by removing one stage from the original two-stage device.
"As best we can tell, the only requirement is to replace the existing secondary, or second stage, with a dummy version, which is what they do every time they test fly a missile," said Young, who noted that the amount of the hydrogen isotope tritium may also be adjusted.
The result is that the yield has been reduced by 95% - from 100 kilotons of TNT to around five kilotons; around 1/3 of the force of the bomb dropped on Hiroshima.


According to the Trump administration, a low-yield nuke will make nuclear war less likely, as the US will have a more flexible deterrent. The W76-2 would be able to counter the perception by enemies (particularly Russia, according to The Guardian) that the US would balk at using its massive nuclear arsenal in response to a similarly small nuclear attack since existing US nukes are in the hundreds of kilotons range, and "too big to use" without massive civilian casualties.
Low-yield nukes "help ensure that potential adversaries perceive no possible advantage in limited nuclear escalation, making nuclear employment less likely" reads the 2018 nuclear posture review.
Critics point out that this is crazy talk which assumes that there are no miscalculations.
"There are many other scenarios, especially with a president who takes pride in his unpredictability and has literally asked: ‘Why can’t we use our nuclear weapons?'" said Young.
Meanwhile Melissa Hanham of the One Earth Future foundation notes that foreign enemies would have no way of knowing if the United States had fired a full-force Trident or the low-yield version.

Hey all you nuclear powers out there. We’re just going to trust that you recognize this is “just a little nuclear weapon” and won’t retaliate with all you’ve got.

Remember! The US only intends to nuke you “a little bit.”

NNSA is moving fast. Has already started assembling the first new low-yield W76-2 warhead. https://twitter.com/leone_exm/status...10109885657090 …

Hans Kristensen, the director of the nuclear information project at the Federation of American Scientists said the new warhead marked a sharp break from the Obama administration policy of making no new weapons or capabilities. He said it risked starting an arms race with Russia involving smaller nuclear weapons.
“To what extent does this signal a new willingness on the part of the US to start using strategic nuclear weapons in a tactical and very limited way early in a potential conflict?” Kristensen asked. “Frankly, mission creep is my greatest worry about this.”
There has been a spate of developments signalling that a new arms race is gathering pace. Vladimir Putin has unveiled a new generation of Russian weapons, and Russia’s suspected development of an cruise missile banned under the 1987 Intermediate-range Nuclear Forces (INF) treaty.
Trump has declared he will take the US out of the treaty, and the administration is expected to suspend compliance and serve six months’ notice of withdrawal on Saturday. -The Guardian

The nuclear weapons review ordered by the Trump administration built upon an ambitious modernization plan which was already underway, and mandated a new sea-launched cruise missile.
The review says that the US could respond with nuclear weapons against "significant non-nuclear strategic attacks," including those on "civilian population or infrastructure." The order also calls for the strengthening and integration "of nuclear and non-nuclear planning."
Democrats could limit
While the first batch of low-yield nukes has rolled off the assembly line, Democrats - who just took over the House, could limit the program.
"I don’t think we need as many as they’re talking about," said Democrat Adam Smith, the new head of the House armed services committee. "I just don’t think we can afford what the NPR is calling for and I don’t think it is necessary."
The nuclear weapons budget is likely to be an important battlefield in the struggle between Trump and congressional Democrats. The president is increasingly surrounding himself with Reagan-era nuclear hawks, including John Bolton, his national security adviser and who pushed for the INF to be jettisoned. Bolton’s new deputy, Charles Kupperman, once argued a nuclear war could be won “in the classical sense” if one side emerged the stronger, even if there were tens of millions of casualties. The Guardian
Former Defense Secretary William Perry told reporters last week that he was less worried about the amount of nuclear warheads remaining in the world than by the dialogue shifting back to said weapons being "usable."
"The belief that there might be tactical advantage using nuclear weapons – which I haven’t heard that being openly discussed in the United States or in Russia for a good many years – is happening now in those countries which I think is extremely distressing," said Perry, adding "That’s a very dangerous belief."
