Destroyer Japan - China in The One World

Destroyer World

Sixty-eight years to the day of the Hiroshima bombing, Japan unveiled its new naval "destroyer" that happens to have a flat-top dubbed "Izumo"  capable of carrying various rotary-wing aviation unit

Consequently,it is also the biggest since war of world II and since Japan's official army was disbanded.

The new boat comes as Chinese officials say the country is in "no rush" to sign a code of conduct guiding military behavior in the contested South China Sea.

Some experts believe the new Japanese ship could potentially be used in the future to launch fighter jets or other aircraft that have the ability to take off vertically. That would be a departure for Japan, which has one of the best equipped and best trained naval forces in the Pacific but which has not sought to build aircraft carriers of its own because of constitutional restrictions that limit its military forces to a defensive role.

The "constitutional restrictions" refer to the American-written post-World War II Japanese Constitution which stipulated — among other things — a ban on the construction of "offensive" military equipment. To this day, Japan euphemistically refers to its army as a Self-Defense Force.

Still, a restless Beijing patrolling n controlling more and more  in the South China Sea, as well as an unpredictable North Korea. They've been pushing for more military spending, some say for fear that American sequester means a shorter reach for Washington in the island disputes.

A destroyer that wants to be a carrier, or visa versa?

Japan's most recent defense white paper covered an increased budget and mentioned Chinese encroachment directly , “China has attempted to change the status quo by force based on its own assertion, which is incompatible with the existing order of international law.”

Two of the aims of Japan's firs increase in defense spending in 11 years were , according to the WSJ, "developing the ability to launch pre-emptive attacks on enemy bases abroad and the creation of an amphibious force similar to the U.S. Marine Corps."

Pre-emptive strikes might actually be in violation of the Article 9 of Japan's constitution, which bars "war" or "threat of use of force" as a means of solving international disputes.

China's natural resources  is growing though, so more Americans and cutters are unlikely to deter their claims. From Reuters:

Friction over the South China Sea, one of the world's most important waterways, has surged as China uses its growing naval might to more forcefully assert its vast claims over the oil- and gas-rich sea, raising fears of a military clash.

Japan's new flat-top doesn't have catapults for fixed wing aircraft — yet — but certainly the helicopters the ship carries will help patrol what Japan takes to be its sovereign territory.

 notably "Britain's HMS Invincible-class ships, which are 209 meters in length."

Nonetheless, they say the ship is primarily for relief from natural disasters, something Japan has had no shortage of over the last few years.

In September, China will host the 10-member Association of Southeast Asian Nations (ASEAN) for talks on a maritime Code of Conduct regulating passage in the South China Sea
