A giant sand wave is sweeping across the North Atlantic in a show of force as the US and UK join forces in a naval exercise.
The US is sending up its largest warship ever, the USS Gerald R Ford, which is part of a fleet of 12 destroyers and a submarine called the USS Sterett.
The two nations are also training together in a joint exercise known as “Sea-Sea Battle”.
The US and Britain are holding the biggest sea-based military exercise since the Cold War, with thousands of US troops taking part in a series of simulated landings, amphibious operations and joint drills.
The exercises, which are known as Sea-Sea Battles, have been going on for decades, but are a huge boost for US President Donald Trump.
The drills are seen as an important part of his effort to reassure his domestic and international audiences about the safety of the US.
In his first foreign trip as president, Mr Trump also made a stop in Britain, where he held a series and a short speech at the White House, which focused on the importance of trade and the economy.
Mr Trump, who is a strong supporter of free trade, has made a lot of promises to his US supporters about the economy, especially during his campaign.
The president has said that the US economy will expand by at least 5% this year.
But, as the exercise draws to a close, there is still a lot to discuss and debate about.
It is not the first time that a giant wave has been seen in the Atlantic, with a wave that was larger than the US fleet.
This time, it is a different type of event, as it is happening at the mouth of the Atlantic Ocean.
The sea-rise comes just days after a giant surge in the North Sea, which came in at 7.8 metres (22 feet) high and 15 metres (46 feet) wide.
It was also a massive event, with the UK coastguard saying it caused a “huge number of reports of high water”.
The sea rose by around 12 metres (33 feet) in the hour after the huge wave hit.
“This was definitely the biggest wave in history,” said Tom McBride, director of the British Geological Survey’s National Geographical Centre.
The surge also brought the total height of the sea to 13.5 metres (41 feet) across the channel.
“It was a very strong event,” he said.
“The US fleet had already gone through a major exercise called ‘Operation Sea-Air Battle’, and it was a major challenge for them.”
The US is still in the midst of the biggest naval exercise in the history of the United States, which was called Sea-Watch.
“This is very significant, because the US navy is very important to the international security of the world.”
The UK has also sent a destroyer to the exercise.
UK Defence Secretary Michael Fallon said the British ship was “going to be the only ship in the US to participate in this exercise”.
“It’s very important, it’s very vital, it gives us an opportunity to show what we can do in this environment,” he told reporters.
“We are very confident that we can make it work, and we have a number of ships in the UK who are going to be involved in the exercise.”
What are the risks of a massive wave?
Experts say the UK’s defence forces will have to do much more than just defend themselves.
“There is a lot that goes into making a big wave,” Mr McBride said.
The waves are also not just big in size, but also can cause damage, with more than 30m people and property being affected by waves in just the past few years.
In one recent example, a storm surge caused more than 200 homes in the Isle of Wight to be submerged, while waves also hit a yacht off the coast of Scotland, with two people killed.
The UK government has said the exercises will help reassure the public about the health of the country.
“These exercises will give the government a lot more confidence in our defences,” said Ms Smith.
“As a country we are getting better at protecting ourselves.”
Experts have warned that a massive rise in sea level could result in the loss of some coastal communities and communities with a lower standard of living.
This could lead to economic problems and more people leaving the country, especially in the poorest parts of the UK.
“In the case of a huge wave, it would certainly be a major issue for the economy of the coastal communities, particularly in Cornwall and Devon,” said Prof Peter Taylor, director at the Centre for International Climate and Environmental Research at the University of Leeds.
Sea levels are rising at a rapid rate in the United Kingdom, and it’s happening now because of climate change.”
