Three U.S. aircraft carrier strike groups will exercise together in the Western Pacific in the coming days in a rare show of force as President Donald Trump visits Asia with warnings about the nuclear threat from North Korea, U.S. officials say.

The drill will include the USS Nimitz, the Ronald Reagan, the Theodore Roosevelt and their accompanying warships, the first time three U.S. aircraft carrier strike groups have exercised together in the region in a decade.

A Japanese destroyer, the Inazuma, will join the armada, two Japanese government officials said, following a separate three-day exercise with the Reagan and two Indian warships in the Sea of Japan that ended Monday.
