US commissions largest-ever warship: What does it mean for Asia?

(CNN)The United States has just sent "a 100,000-ton message to the world," says US President Donald Trump.
The message comes in the form of the aircraft carrier USS Gerald R. Ford, a $13 billion behemoth commissioned into the US Navy's fleet on Saturday.
"Wherever this vessel cuts through the horizons, our allies will rest easy and our enemies will shake with fear because everyone will know that America is coming and America is coming strong," Trump said.
Although the Ford's deployments are far off and yet to be determined, it has officially joined a US military arsenal trying to stay supreme in the face of new challenges in an increasingly tense North Asia.
China has recently launched its second aircraft carrier and its most-advanced destroyer ever. Those came shortly before Beijing sent its other aircraft carrier, the Liaoning, in a display of power to Hong Kong, and other warships to show their might as far away as Europe.
Meanwhile, North Korea has tested its first intercontinental ballistic missile, one that theoretically puts Alaska in range of Pyongyang's military reach and has Hawaii readying missile defense drills.
With all that in mind, CNN looks at the military state of play in North Asia. What are the comparative strengths and weaknesses of the players in the region?
The United States remains the world's preeminent military power, and in the Pacific it fields large numbers of technologically advanced weapons.
The US Pacific Command "is prepared to fight tonight with the best technology of any force on the planet," Adm. Harry Harris, commander of the more than 340,000 US troops in the Pacific, said in a February speech.
The US has 11 active aircraft carriers and more in production. In comparison, China has just launched only its second aircraft carrier, but that ship won't be ready for action for a few years.

While only one of those US carriers, the USS Ronald Reagan, is based in Asia, the 97,000-ton warships with their complement of 60-plus warplanes can be moved within the space of a few weeks to global hot spots, as evidenced when the Navy sent the San Diego-based USS Carl Vinson to the South China Sea in February and its later movement to the Korean Peninsula.
While those new additions to the region may be making the recent headlines, the US has maintained a robust force at bases from Japan to Australia.
Kadena Air Base on the Japanese island of Okinawa is home to the US Air Force's 18th Wing, billed as the largest combat-ready wing in the service. More than 50 F-15 Eagle fighters are based at Kadena, supported by tankers and AWACS command and control aircraft.
In South Korea, the US maintains two major air bases, Osan with F-16 fighters and A-10 "tank killers," and Kunsan with F-16s.
Additional heavy airpower can be called in from the Pacific island of Guam, through which the US rotates B-1, B-2 and B-52 bombers.
Measured by active duty manpower alone, the North Korean military is huge. Pyongyang has almost 1.2 million men and women in uniform, putting it behind only China, the United States and India among the world's largest militaries.
From an armaments standpoint, however, North Korea's isolationism has left it behind much of the world technologically, meaning it can't field the quality of weapons that adversaries such as South Korea, the US and Japan employ. But that doesn't mean it can't do catastrophic damage to its enemies.
"The North Korean military's most powerful tool is artillery," says Stratfor, a geopolitical analysis firm based in Texas.
According to the International Institute for Strategic Studies, North Korea can field 21,000 artillery pieces. Many of those are within range of the 25 million South Koreans living in the Seoul metropolitan area, meaning the North could launch an artillery barrage that could kill thousands -- and possibly many more.
South Korea fields some of the world's most-advanced weaponry, all focused on protecting it from the threat posed by the North.
The International Institute for Strategic Studies points out that Seoul has procured or will get advanced weaponry, including a fleet of F-35 stealth fighters, cruise missiles for its F-15 fighters, and new submarines.
Seoul will also be adding to its fleet of Sejong the Great-class guided-missile destroyers, already considered among the world's most-advanced warships.
"They make a competitive case to be the Pacific region's leading modern multi-role heavy surface combatant, while providing an important platform for new South Korean weapons," Defense Industry Daily wrote of the Sejong the Great destroyer, which are even bigger than US guided-missile cruisers.
On the ground, Seoul's force includes 100 of its domestically produced K2 "Black Panther" tanks, considered among the best in the world by analysts.
"Pilot for pilot, ship for ship, Japan can stand toe to toe with anybody," said John T. Kuehn, a professor of military history at the U.S. Army Command and General Staff College.
Tokyo's naval forces, known as the Maritime Self-Defense Force, are particularly strong and adept at anti-submarine warfare, experts say.
"Subsurface detection and reaction is a Japanese strength in both technological and operational terms," said Corey Wallace, a security analyst at Freie University in Berlin.
China has the world's largest military by sheer quantity, with more than 2.1 million active duty personnel.
On and under the sea, Beijing has impressive numbers of submarines (64) and large surface ships (82), which give adversaries something to worry about in quantity. However, analysts say the Chinese fleet falls short of those adversaries in quality.
China's biggest asset, however, may be its missile force.
China also boasts newly developed air-launched, land-attack cruise missiles which can be fired by its fleet of H-6K long-range bombers.
