So on Friday, the Navy took its newest aircraft carrier, [2]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 [12]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 [13]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. ®

Re: That truck video is Awesome!
If they were going for the stone skipping record, they need to work a bit more on the reproducability of their throws. Those trucks hit at very different angles sometimes. You would have thought that an elctromechanical system would produce more reliable results than that.
(always presuming they weren't testing different energies, of course)
Re: That truck video is Awesome!
> always presuming they weren't testing different energies, of course
I'm pretty sure they were testing the pull of the catapult at different energies - different jet fighter models have different takeoff acceleration requirements.
Odd Name
I find it odd that the United States would call a navy ship Gerald R Ford.
I assumed Americans are all completely embarrassed that he ever ran the joint, and they just pretend they didn't have a president between 1974 and 1977.
Maybe the next one they build will be the Richard M Nixon.
Re: Odd Name
It's because he served in the Navy. The next carrier in the same class will be called the John F Kennedy for the same reason.
boom.
Its also a great way to get rid of any pesky subs that happen to be trying to calibrate signature detection
Fish Supper
The Navy chefs must have been busy preparing for dinner afterwards.
Wildlife
I wonder whether there will be any analysis of the wildlife killed or otherwise harmed by the explosion? Did they choose a place that was as far away as possible form known whale locations?
I realise that the USN has to do tests, but I do hope they don't have to do any more like this for a very long time.
That truck video is Awesome!
Slightly deranged, but awesome.
