Britain's most advanced and biggest warship, the 65,000-ton aircraft carrier HMS Queen Elizabeth, berthed for the first time at its home port of Portsmouth on Wednesday.
The 280-meter (920-foot) vessel entered the harbor on England's southern coast at 0610 GMT, greeted by thousands of spectators.
HMS Queen Elizabeth is the largest warship ever built for the Royal Navy, according to the Ministry of Defense.
"Today we welcome our mighty new warship, HMS Queen Elizabeth, to her home for the very first time," said Defense Secretary Michael Fallon. "She is Britain's statement to the world: a demonstration of British military power and our commitment to a bigger global role."
The ship is currently undergoing sea trials. It cannot yet deploy planes, but flying trials from its deck are due to begin in 2018.
It took eight years to build HMS Queen Elizabeth, with construction taking place in six cities and involving 10,000 people.
Along with its sister ship, HMS Prince of Wales, it is part of a defense program worth 6 billion pounds ($7.65 billion).
Commanding officer Captain Jerry Kyd told the BBC that the carrier "sends the right signals to our allies and indeed potentially to our enemies that we mean business."
