The South Korean navy has begun to remake itself from a coastal patrol force intended to foil North Korea into a blue water fleet able to project power onto the high seas, which has implications rippling out from Seoul to Singapore.
In late May, the navy launched its first AEGIS destroyer, a high-tech ship designed to fight other ships, chase submarines and defend against aerial attacks.
Two more AEGIS destroyers are to be added over the next five years, at a total cost of US$3.4 billion, with three more possible after that.
Beyond that are plans for nine smaller destroyers, the same number of frigates, 32 corvettes, and more than 100 other patrol ships, minesweepers and logistic vessels to be built over the next 15 years.
Two large amphibious ships, and maybe a third, will each carry a battalion of 750 marines and 15 helicopters. Added to that will be 23 landing craft.
For missions under the sea, the South Koreans plan to acquire 36 diesel-electric submarines. In the air, the navy plans to obtain eight to 16 P-3C anti-submarine planes and nearly 60 helicopters. A new base is on the drawing board for the island of Cheju at the southern tip of the peninsula to give the new fleet access to the East China Sea and the Pacific Ocean.
The reasons for the buildup of the Republic of Korea Navy (ROKN) are many. At the launch of the new destroyer on May 31, President Roh Moo-hyun suggested that national pride was a priority for a Korea that he hopes will be reunified one day soon.
"South and North Korea will not keep picking quarrels with each other forever," the president said.
Looking to a reunified Korea, he said: "We have to equip the nation with the capability to defend itself. The AEGIS destroyer we are dedicating today could be the best symbol of that capability."
Roh returned to a theme that has marked his presidency for four years, which is to have South Korea rely less on the US for security.
"We have to build up an adequate ability in all areas that constitute war power," he said, "so that we will be able to defend ourselves without fail."
The name of the new ship, King Sejong the Great, is emblematic. Ruling from 1418 to 1450, King Sejong is best known for having fostered a simplified form of writing that enabled all Koreans to read and write. But he also sent Korean forces to fight Chinese in Manchuria and Japanese pirates.
Today, South Koreans are divided between those who would retain the alliance with the US forged in the Korean War and those who seek independence or a tilt toward China.
Many naval officers, having operated with the US Navy for years, favor a continued alliance.
"The Korean Navy," said an admiral, "should build a force that can support the ROK-US alliance."
Those officers, however, appear to harbor the same antipathy toward Japan as most of their compatriots and suggest that their new fleet may one day confront Japan, which ruled Korea with an iron hand from 1910 to 1945. At the very least, they see Japan as a rival whose fleet they aim to match.
US officials, who consider their alliance with Japan vital to their security posture in Asia, privately lament the Korean attitude toward Japan.
Some have urged the Koreans to put the past behind them and to dismiss what one called "the myth that Japan is going back to the militarism of the 1930s."
US officials suggested that the US would applaud the ROKN's plan, provided the South Koreans continued to operate with the US Navy and resolved their differences with Japan.
As it has expanded over the last three decades, the South Korean economy has come to depend heavily on imports and exports.
That trade is seaborne because South Korea is cut off from Asia by the demilitarized zone that splits the peninsula. Korea imports, for instance, 78 percent of its petroleum from the Middle East through the Malacca Strait and the South China Sea in Southeast Asia, which are vulnerable to pirates and terrorists.
"There is no doubt," concluded a naval officer, "that the ROK's future prosperity depends on the use of the sea. Building a naval force to defend this maritime domain is becoming a key issue in the ROK's future national security strategy."

The US Senate’s passage of the 2026 National Defense Authorization Act (NDAA), which urges Taiwan’s inclusion in the Rim of the Pacific (RIMPAC) exercise and allocates US$1 billion in military aid, marks yet another milestone in Washington’s growing support for Taipei. On paper, it reflects the steadiness of US commitment, but beneath this show of solidarity lies contradiction. While the US Congress builds a stable, bipartisan architecture of deterrence, US President Donald Trump repeatedly undercuts it through erratic decisions and transactional diplomacy. This dissonance not only weakens the US’ credibility abroad — it also fractures public trust within Taiwan. For decades,
In 1976, the Gang of Four was ousted. The Gang of Four was a leftist political group comprising Chinese Communist Party (CCP) members: Jiang Qing (江青), its leading figure and Mao Zedong’s (毛澤東) last wife; Zhang Chunqiao (張春橋); Yao Wenyuan (姚文元); and Wang Hongwen (王洪文). The four wielded supreme power during the Cultural Revolution (1966-1976), but when Mao died, they were overthrown and charged with crimes against China in what was in essence a political coup of the right against the left. The same type of thing might be happening again as the CCP has expelled nine top generals. Rather than a
The ceasefire in the Middle East is a rare cause for celebration in that war-torn region. Hamas has released all of the living hostages it captured on Oct. 7, 2023, regular combat operations have ceased, and Israel has drawn closer to its Arab neighbors. Israel, with crucial support from the United States, has achieved all of this despite concerted efforts from the forces of darkness to prevent it. Hamas, of course, is a longtime client of Iran, which in turn is a client of China. Two years ago, when Hamas invaded Israel — killing 1,200, kidnapping 251, and brutalizing countless others
Taiwan’s first case of African swine fever (ASF) was confirmed on Tuesday evening at a hog farm in Taichung’s Wuci District (梧棲), trigging nationwide emergency measures and stripping Taiwan of its status as the only Asian country free of classical swine fever, ASF and foot-and-mouth disease, a certification it received on May 29. The government on Wednesday set up a Central Emergency Operations Center in Taichung and instituted an immediate five-day ban on transporting and slaughtering hogs, and on feeding pigs kitchen waste. The ban was later extended to 15 days, to account for the incubation period of the virus
