A U.S. aircraft carrier visited Thailand this week, while a French carrier reached the edge of the Western Pacific Ocean as it stopped in Indonesia after a multinational war game.

Meanwhile, the Chinese military did not deploy any of its aircraft carriers, two of them remaining pierside at bases, while another underwent maintenance inside a dry dock.

Newsweek‘s weekly update maps aircraft carrier movements in the Indo-Pacific region. As of January 31, the locations of 12 vessels were publicly available via military disclosures, as well as open-source imagery captured by satellites or ship-spotters. The U.S. military has the world’s largest “flattop” fleet with 11 in service. China ranks second with three.
