The report does worry about direct tampering with the warheads, though. McNeill claims to have scurried around inside a missile, right next to them. The crew follows orders when firing a missile but ultimately has autonomy. The US ballistic system uses a Permissive Action Link PAL which means that the chiefs of staff have to send their nuclear launch site a code before the missile can be fired.

Accounts differ over whether the code was set to all-zeroes for more than a decade. When configured properly, though, this avoids a megalomaniac with a short temper firing the missiles in a hissy fit, by keeping the president in charge oh, wait. The report worries that an attacker could hack the very low frequency radio that sends data to the subs at baud. They could use it to manipulate malware aboard the vessel, or simply mislead and confuse the crew into firing or not firing a nuke, they say.

What does all this mean?

On the one extreme, you have the doomsday dramatists. On the the other extreme, you have the denialists.

The UK government claims that Trident is safe because it is air-gapped, but safety is never absolute. The vulnerability to cyberattacks is real. It can be reduced by significant, vigilant and continuous cyber protection, but cannot be eliminated. But this is basic cybersecurity theory. The isolated nature of the ships elevates security by an order of magnitude, and claims of air-gap hacking are speculative and futuristic.

The christening of the USS South Dakota

There are plenty of those, both direct and indirect. McNeill says that he already did. In , the world almost went to war because the Russians thought a NATO exercise was going to turn into a real nuclear attack, and went on hair trigger alert. In that same year, a satellite malfunction sent false signals of a massive incoming nuclear strike to this Soviet technician , who thankfully ignored them. In an ailing US plane actually bombed North Carolina with a nuke that nearly went off.

During the Cuban missile crisis, a bear on an airforce base set of an alarm that had ground crews scurrying for takeoff. There are many more such stories.

‘Anti-Access/Area Denial’

If the world does end in a bang, it might not be because a smart state actor got control of the switch. Sleep well. Follow NakedSecurity on Twitter for the latest computer security news. Having passed all the dockside tests, the seagoing trials began. Once the ship was well out to sea, May 2, , the computer crashed and could not be re-started.

It was later found to be a divide-by-zero error. The Yorktown had to be towed back to port.

Hacking nuclear submarines – how likely is the nightmare scenario?

The new boats might be different but I would honestly suspect any compromise would come through the supply chain during construction rather than a skiddy via wifi.

Cuban missile crisis | History, Facts, & Significance |

Such exercises during such a crisis situation would be highly unlikely unless the ship was carrying nuclear weapons, strongly suggesting that the ship was nuclear armed during its preceding visit to Japan. Contingency plans existed in for deployment of the Genie air-to-air missile to Japan.

Although the Genie missile is dual-capable, the documents clearly identify the missiles that would be deployed under these contingencies as nuclear missiles. This represents the first association of nuclear-armed Genie missiles with Japanese deployment. The details of the contingencies under which the missiles would be deployed remain classified.

Whether the Japanese forces participated directly in practicing these procedures is unknown. With the reversion of Okinawa to Japanese sovereignty in , Japan stated that all nuclear weapons related functions on the island must cease. Despite this position, U. Although nuclear weapons were removed from Okinawa in the early s, this was not simply in response to the conditions for reverting the island to Japanese sovereignty, but was undertaken as part of a much larger U. The newly declassified documents confirm for the first time that U. Previous Nautilus Institute research has provided the first official account of how nuclear weapons were removed from South Korea in At about the time of the reversion of Okinawa to Japan in , both the Commander in Chief of the U.

Note the relevance of this finding to those outlined in the following section. In addition to the question of whether the United States deployed nuclear weapons and conducted nuclear operations in Japan throughout the Cold War, there have also been frequent allegations among analysts and in news media that U. The most widely reported of these allegations is that the United States and Japan, in connection with negotiation of the Treaty of Mutual Cooperation and Security, reached a secret unwritten understanding to permit U.

The newly declassified documents obtained for this report provide ample evidence that Japanese governments willingly overlooked indications that its non-nuclear principles were violated. The declassified material also confirms that the U. In some instances, Japanese officials were present onboard U. The newly declassified documentation even reveals instances in which Japanese government officials urged the United States to conceal the armament of the nuclear ships.

Nowhere is the Japanese willful disregard of U. The report shows how the Japanese government simply decided to ignore the weight of the evidence and ride out the storm of public criticism. Thus, Japanese governments consistently exercised a contradictory, if not hypocritical, attitude toward U. In public, Japanese governments stood by the nuclear ban devoutly, and reiterated it each time the government was confronted with evidence of a violation. In private, however, governments maintained a more pro-nuclear disposition epitomized by tacit acceptance of the nuclear ambiguity demanded by the NCND policy.

The coexistence of these two contradictory positions imposed a burden on Japanese policymakers and created a tension in U. Although the arrangement accommodated conflicting political and security imperatives of the day, its perpetuation has damaged the credibility of the U. The U.

However, the United States continued to insist on complete secrecy concerning its nuclear weapons practices, leaving Japanese authorities to deal with the political fallout.
