Queen Elizabeth II has attended the commissioning ceremony of Britain's new aircraft carrier, which is named after the monarch.
The 91-year-old queen boarded the Royal Navy's newest, largest and most expensive vessel Thursday in Portsmouth naval base.
The white ensign was raised to mark the moment HMS Queen Elizabeth was officially added to the Royal Navy's fleet. The queen says the ship "embodies the best of British technology and innovation."
