US Navy starts an earthquake to see how its newest carrier withstands combat conditions

Who are they expecting to fight? Thor? Godzilla? Sea snails?

Following the recent decision by the United States Air Force to assassinate four snails and 90 giant clams in the name of missile research, the US Navy obviously felt that it, too, should be doing something faintly bizarre with its shiny, expensive equipment.

So on Friday, the Navy took its newest aircraft carrier, the 100,000 tonne USS Gerald R Ford, parked it in the Atlantic Ocean 100 miles (160km) from the Florida coast and subjected it to an enormous explosion (see video below).

The detonation was part of what the US Navy describes as a Full Ship Shock Trial or FSST, which is supposed to check whether a vessel can withstand combat conditions and deal with near misses during wartime.

The Gerald R Ford is the first of a new class of US Navy carrier that is planned to eventually include 10 vessels, so it received the dubious honours of undergoing the trial on behalf of its future classmates, as well as being the first aircraft carrier to be blown up by the US Navy since the USS Theodore Roosevelt in 1987. Friday's blast was intended to be the first of three trial detonations.

Other US Navy ships to have been subjected to huge explosions in this way include the guided missile cruiser USS Mobile Bay (1987), the amphibious assault ship USS Wasp (1990), the amphibious transport dock USS Mesa Verde (2008), and the Littoral Combat Ships USS Jackson and USS Milwaukee (2016).

The explosion reportedly used 18 tonnes (40,000 lbs) of explosives, which created a blast large enough for the US Geological Survey to record it as a 3.9-magnitude earthquake.

The Navy said in a statement that the shock trial had been conducted "within a narrow schedule that complies with environmental mitigation requirements, respecting known migration patterns of marine life in the test area."

While this may not have fully prevented the blast from harming local wildlife, it is certainly an improvement on the USAF's efforts to target individual animals with hypersonic missiles.

Despite being the USN's newest carrier, having only been accepted in 2017, this is not the only peculiar test the Gerald R Ford has been involved in. Before it was even commissioned it was filmed firing trucks into the James River from its berth at Newport News Shipbuilding in 2015.

These unruly shenanigans were a trial of its Electromagnetic Aircraft Launch System catapult, a new system used for launching aircraft from its flight deck. (Be aware that the sound and pictures do not line up in the video below.)

Presuming it survives the three-explosion FSST test programme, the USS Gerald R Ford is scheduled to go into dock for six months of maintenance and repairs shortly afterwards, although it is not clear how much of this will be due to it having just been subjected to three earthquakes. ®

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.

  • Big Tech loves talking up privacy – while trying to kill privacy legislation
    Study claims Amazon, Apple, Google, Meta, Microsoft work to derail data rules

    Amazon, Apple, Google, Meta, and Microsoft often support privacy in public statements, but behind the scenes they've been working through some common organizations to weaken or kill privacy legislation in US states.

    That's according to a report this week from news non-profit The Markup, which said the corporations hire lobbyists from the same few groups and law firms to defang or drown state privacy bills.

    The report examined 31 states when state legislatures were considering privacy legislation and identified 445 lobbyists and lobbying firms working on behalf of Amazon, Apple, Google, Meta, and Microsoft, along with industry groups like TechNet and the State Privacy and Security Coalition.

  • SEC probes Musk for not properly disclosing Twitter stake
    Meanwhile, social network's board rejects resignation of one its directors

    America's financial watchdog is investigating whether Elon Musk adequately disclosed his purchase of Twitter shares last month, just as his bid to take over the social media company hangs in the balance. 

    A letter [PDF] from the SEC addressed to the tech billionaire said he "[did] not appear" to have filed the proper form detailing his 9.2 percent stake in Twitter "required 10 days from the date of acquisition," and asked him to provide more information. Musk's shares made him one of Twitter's largest shareholders. The letter is dated April 4, and was shared this week by the regulator.

    Musk quickly moved to try and buy the whole company outright in a deal initially worth over $44 billion. Musk sold a chunk of his shares in Tesla worth $8.4 billion and bagged another $7.14 billion from investors to help finance the $21 billion he promised to put forward for the deal. The remaining $25.5 billion bill was secured via debt financing by Morgan Stanley, Bank of America, Barclays, and others. But the takeover is not going smoothly.
