Providing security at sea

The UK has a responsibility to its citizens and its allies to endeavour to safeguard the high seas. This is why the Royal Navy protects home and international waters – making sure the global trade that Britain and the world depend on can proceed without a hitch.

Protecting our economy

Maritime trade is the lifeblood of the UK economy and industry. 95% of Britain’s economic activity depends on the oceans. And every year Britain imports goods worth £524 billion.

The UK is so dependent on the seas for its prosperity, that without the Royal Navy acting as a deterrent the effect on the economy would be overwhelming.
