The News That Matters about the Nuclear Industry

Ever growing risk of ‘Accidental’ Nuclear War

Risk of ‘Accidental’ Nuclear War Growing, UN Research Group Says, The warning comes as the Pentagon begins an extensive review of its nuclear arsenal. Defense One, BY PATRICK TUCKER, 19 APR 17, 

On Sept., 26, 1983, shortly after midnight, the Soviet Oko nuclear early warning system detected five missiles launched from the United States and headed toward Moscow. Stanislav Petrov, a young lieutenant colonel in the Soviet Air Defense Force, was the duty in the Serpukhov-15 bunker that housed the Oko command center. Petrov was the man in charge of alerting the soviets about a nuclear attack, which would trigger a retaliatory strike. He determined that the Oko had likely malfunctioned and the alarm was false. The Americans would not start World War III with a quintet of missiles (risking total annihilation.) It was a daring judgment call. He was, of course, right. As the U.S. prepares to undertake a new nuclear posture review to determine the future direction of the nation’s nuclear weapons, a report from a United Nations research institute warns that the risks of a catastrophic error — like the one that took place that early morning in 1983 — are growing, not shrinking. Next time, there may be no Lt. Col. Petrov in place to avoid a catastrophe.

On Monday, the U.S. Defense Department commenced a new, massive study into its nuclear weapons arsenal, looking at how weapons are kept, how the U.S. would use them in war and whether they present an intimidating enough threat to other countries not to attack us. The review was mandated by President Trump in a Jan 27, memo.

The Pentagon is scheduled to complete the review by the end of the year, an essential step as the military seeks to modernize different aspects of its nuclear deterrent. But a new report from the United Nations Institute for Disarmament Research, or UNIDR, argues that as the modern battlefield becomes more technologically complex, crowded with more sensors, satellites, drones, and interconnected networks, the risks of another nuclear accident are on the rise.

“A greater reliance on automated systems can lead to misplaced confidence while introducing new points of vulnerability,” says the report. Those new points of vulnerability include so-called “hidden interactions.” That means a sensor or computer program misinterpreting some bit of data and possibly presenting false information in a way that could cause an accident. The 1987 incident provides a good case in point. Oko satellites mistook a very unusual sunspot on top of a high altitude cloud as a missile strike, hence the false alarm.

Take those satellites, combine them with sensors on drones and data from other sources as well, including new, perhaps unproven technologies to detect missile launches and the picture becomes much more crowded and murky.

“The complex interactions and tightly coupled systems linked to nuclear arsenals (like those for early warning, and launch command and control) have made ‘accidental war more likely’” the report’s authors say.

Add to that the fact that the number of states that have access to nuclear weapons is increasing, and the number of platforms that they might be able to use to deliver those weapons is also going up. Consider the controversial U.S. plans for a long-range standoff weapon, or LRSO, basically a big nuclear cruise missile that can be fired off a fighter jet.  Reports have surfaced that the U.S. is even considering nuclear-armed drones (that would be remotely operated by human pilots and the degree of seriousness in the considerations is up to debate).

Those might sound like awesome capabilities but they increase the chances of a nuclear accident or retaliatory strike, according to the authors of the report, because such weapons essentially turn every jet and drone into a potential nuclear threat in the eyes of an adversary……http://www.defenseone.com/technology/2017/04/risk-nuclear-accidents-growing-un-research-group-says/137171/?oref=defenseone_today_nl
