A US service strike group – a serious fleet of warships – is a potent image of American navy energy and a sign that it is prepared to defend allies and deter enemies.
So the presence of such a drive within the North Sea over the previous few weeks is supposed to reassure European allies, regardless of the political uncertainties again residence.
American navy energy has helped shield Europe for the previous 75 years – however the US presidential election raises the query: for a way for much longer?
Navy commanders do their greatest to keep away from politics.
However amongst a bunch of journalists invited on board the USS Harry S Truman, the US presidential race was excessive on the agenda. The query was: will America nonetheless have Europe’s again?
Rear Adm Sean Bailey mentioned: “What I can inform you is we’re firmly dedicated to our alliance, firmly dedicated to Nato.”
However he isn’t the one who can be deciding US international coverage, and neither is his reply more likely to assuage doubts.
Germany’s Defence Minister, Boris Pistorius, is aware of change is within the air.
Requested in regards to the probably affect of the US election on Europe final week, he mentioned it was a query of whether or not America does “so much much less, or somewhat bit much less”.
He did not point out names, nevertheless it’s Donald Trump who’s more likely to do so much much less.
USS Harry S Truman proudly bears the title of the president who helped set up Nato 75 years in the past.
However a second Trump time period may as soon as once more shake the alliance to its very core.
The Truman doctrine of giving navy, financial and political help to democratic nations below risk could be very completely different to Trump’s coverage of America First.
He just lately mentioned Russia can “do regardless of the hell they need” to allies who do not spend sufficient on defence.
Any US withdrawal from Europe would depart a big gap.
The USS Harry S Truman is proof of what America brings in sheer measurement and numbers – with 5,000 crew and greater than 60 plane.
The Royal Navy’s service, HMS Prince of Wales, crusing close by, offered a reminder of Europe’s extra modest defences.
The British service was crusing with an air wing of some helicopters and eight F-35 jets – a pale reflection of US navy clout.
General the US has greater than 100,000 navy personnel deployed in Europe.
Final time he was president, Trump threatened to withdraw a few of these forces. If elected he may do the identical once more.
Many Republicans consider Europe ought to take care of itself. That is definitely the view of Elbridge Colby, a senior Pentagon official within the final Trump administration.
He says the US ought to “withhold” its forces from Europe to concentrate on the risk posed by China.
The election can even have an effect on US navy help to Ukraine – America is by far its greatest navy backer.
However a senior Nato official, who didn’t wish to be named, just lately instructed the BBC “no matter who wins the share of America’s contribution to Ukraine will in all probability lower in relative phrases”.
Europe, he mentioned, cannot count on the US to proceed giving an “outsized” contribution.
The truth is that America’s navy focus has already been shifting east to the Indo-Pacific area and the rise of China.
The Pentagon identifies China as its best safety problem. China now has a bigger navy than the US. It is constructing a fleet the scale of the complete Royal Navy each two years.
The sailors and pilots on board the service recognise there is a pivot east too.
Cdr Bernie Lutz has spent a lot of his naval profession flying F-18s off a US service within the Pacific and Center East.
He recognises why they’re now crusing in European waters. “There’s so much occurring,” he says.
However he provides, “I believe the Pacific theatre is the larger, overarching long-term purpose”.
Like the remainder of the 5,000-strong crew of the service, he has not but been instructed the place they will be crusing subsequent – nevertheless it’s been extensively reported that the USS Harry S Truman will quickly be on its strategy to the Center East.
That area, too, will stay a problem for whoever’s president subsequent.
Capt Dave Snowden says he is blissful to hold the banner of de-escalation or deterrence and even sail into hurt’s manner – wherever the service’s despatched.
However the lack of significant international coverage debate within the election displays a reluctance to get instantly concerned in additional wars.
America will nonetheless stay the world’s most pre-eminent navy energy.
The query is how will the following president use it.
