SOUNDBITE: Britain's Queen Elizabeth II, saying (English):
"I name this ship Queen Elizabeth may all god bless her and all who sail in her."
Britain's Queen Elizabeth names the UK's newest and biggest warship.
At 280 metres long, the aircraft carrier The HMS Queen Elizabeth is the size of 3 football pitches and weighs 65,000 tonnes.
It was built in shipyards around the UK.
The project hasn't been without controversy.
It's taken five years to complete and ran massively over budget - costing 6.2 billion pounds - double the original estimate.
Now she's built there are also worries about the jobs of the 4,000 people who worked on her in Scotland, particularly if the country votes to become independent.
Scotland's First minister Alex Salmond dismissed the concerns.
SOUNDBITE: Alex Salmond, Scottish First Minister, saying (English):
"Rosyth's been around for 100 years, it will be around for another 100 years and it will be building great ships, refitting ships for the north sea. And I think he should glance over to Norway, to see the huge tonnage of ships they're building, if they can do it, Scotland can do it and we won't be depending on the grace and favour of a Tory prime ministers."
But David Cameron is determined to keep Scotland in the UK.
And announced a £500 million investment for its biggest city Glasgow.
SOUNDBITE: David Cameron, UK Prime Minister, Saying:
"Let's be clear that if the United Kingdom stays together as I hope it will. Glasgow will continue to be an absolute centre of excellence in terms of shipbuilding."
The vote on independence takes place on September 18 and the No supporters have a majority at the moment.
IG's Alistair McCaig says the Yes campaign still has some convincing to do.
SOUNDBITE: Alistair McCaig, Market Analyst, IG, saying (English):
"I think the problem with the Yes vote is there are still far too many questions that need to be answered as to exactly what the tax situation might be, what currency they might be using and it doesn't create a level platform with which companies can feel confidence to build their outlook for the future."
HM Queen Elizabeth is one of a pair.
The second, the Prince of Wales will be built in a few years.
But the government is yet to decide whether to use her or to sell her.
