Two of Britain's and America's most powerful ships met up on Tuesday during their break from sea trials and training.

HMS Queen Elizabeth, the UK's new £3.5 billion ($4.6 billion) aircraft carrier, passed by the USS George H.W. Bush off the Scottish coast en route to its new home port of Portsmouth.

The British mega-ship has spent the summer conducting its first sea trials in the North Sea, while its US counterpart was in the Persian Gulf supporting ground troops in their fight against ISIS.

The Queen Elizabeth is now in British waters to take part in the training exercise known as Saxon Warrior, where it is hosting 60 members of the British Royal Navy and Royal Marines. The training began on August 1.
