China sent all of its operational aircraft carriers to sea this week, while a United States “flattop” remained in the Philippine Sea, a marginal sea in the Western Pacific Ocean.

This came as the Pentagon released its annual report on Chinese military power that said Beijing deployed an aircraft carrier beyond the first island chain, a north-south blockade formed by Japan, Taiwan and the Philippines under a U.S. defense concept, three times during the year, a record number for a calendar year.

Newsweek‘s weekly update maps aircraft carrier movements in the strategic Indo-Pacific region. As of December 20, the locations of 11 vessels were publicly available via military disclosures or open-source satellite imagery. The U.S. military has the largest aircraft carrier fleet in the world, with 11 in service. China ranks second with three “flattops.”

USS Carl Vinson: Philippine Sea

According to a photo published by the U.S. Navy, the Carl Vinson continued to operate in the Philippine Sea as of Friday. The aircraft carrier received additional F-35C Lightning II stealth fighter jets last week, following a Chinese war game conducted around Taiwan.

USS George Washington: Yokosuka, Japan

The George Washington remained pierside at Yokosuka naval base, its home port in the Greater Tokyo Area, during its second deployment to Japan as of Friday, according to a local government website that tracks port visits made by U.S. nuclear-powered warships.

USS Abraham Lincoln: Eastern Pacific Ocean

According to a photo published by the U.S. Navy, the Abraham Lincoln was underway in the Third Fleet’s area of operations, which covers the eastern part of the Pacific Ocean. The aircraft carrier was returning from a surge deployment in the Middle East.

USS Nimitz and USS Ronald Reagan: Bremerton, Washington

The latest clear satellite image of the Puget Sound Naval Shipyard, which is part of Naval Base Kitsap in Bremerton, Washington, appeared to show that two aircraft carriers, the Nimitz and the Ronald Reagan, pierside at the shipyard on December 15.

According to a ship spotting account on X, formerly Twitter, the Nimitz was pierside at the shipyard on December 11 and the Ronald Reagan sailed into Bremerton two days later.

Japan Maritime Self-Defense Force

JS Kaga: Kure, Japan

The Kaga, which is a helicopter destroyer undergoing conversion into the country’s first aircraft carrier since World War II, arrived at Kure naval base in Hiroshima Prefecture on December 15. The prefecture is in the southwestern part of Japan’s main island of Honshu.

It returned to Japan following trials at sea with fighter jets off the U.S. West Coast and a stopover at Pearl Harbor in Hawaii. Its namesake was an aircraft carrier that launched the air raid on Pearl Harbor on December 7, 1941, which led the U.S. to declare war on Japan.

JS Izumo: Yokohama, Japan

Japanese media reported that the Izumo, the sister ship of the Kaga, remained at a shipyard in Yokohama, southwest of Tokyo. Its conversion to a light aircraft carrier is scheduled to be completed in 2027, meaning it will remain docked at the shipyard for the next three years.
