China's most advanced bombers seen on disputed South China Sea island

Highlights:

• Satellite images show two advanced bombers on Woody Island
• H-6 bombers fitted with anti-ship and land attack cruise missiles
• Presence signals advanced capability amid regional tensions

Satellite imagery shows China landed two of its most advanced bombers in the disputed Paracel islands in the South China Sea this month - a gesture that some analysts described as Beijing's latest signalling of its growing military capabilities to rivals.

The deployment marks the first time the long-range H-6 bombers have landed on Woody Island in the Paracels since 2020, and the movement of the now upgraded aircraft comes amid tensions with the Philippines, operations near Taiwan and ahead of the region's biggest defence forum this weekend.

"China's long-range bombers don't need to be on the Paracels so it does appear to be omni-directional signalling by Beijing - against the Philippines and against the US and other things that are going on," said Collin Koh, a defence scholar at Singapore's S. Rajaratnam School of International Studies.

French President Emmanuel Macron is due to open the three-day Shangri-La Dialogue forum in Singapore with a speech on Friday while US Defence Secretary Pete Hegseth will outline the Trump administration's approach to the region on Saturday.

A British aircraft carrier is expected in the South China Sea on a rare deployment next month, diplomats say. Satellites captured two H-6 planes flying over the hotly disputed Scarborough Shoal, also in the South China Sea, just ahead of Hegseth's visit to the Philippines in late March, when he reaffirmed the United States' "ironclad commitment" to its treaty ally.

Regional diplomats and analysts say deployments of the jet-powered H-6 are closely scrutinised, given the way its Cold War-era airframe has been modernised to carry anti-ship and land attack cruise missiles, while some of the planes are capable of launching nuclear-tipped ballistic missiles.

A potential threat to US bases in the region, H-6 bombers were deployed in wargames around Taiwan in October, and in July flew close to the US mainland for the first time.

Neither China's defence ministry nor the Philippines' maritime and national security council immediately responded to Reuters' requests for comment.

China's occupation of the Paracels is disputed by Vietnam, whose foreign ministry also did not immediately respond for comment.

SOVIET DESIGN

Echoing the development of the US B-52, the basic H-6 dates back to 1950s Soviet designs but it remains China's most advanced long-range bomber having been re-fitted with improved engines and modern flight systems along with its state-of-the-art weaponry.

Images provided to Reuters by Maxar Technologies show two H-6 bombers on a runway on Woody Island on May 19.

Another Maxar image on the same date show two Y-20 transport aircraft and an KJ-500 early warning plane - an aircraft that is seen as vital to China being able to control and secure increasingly complex air and sea operations.

Some analysts said the planes may have first arrived on May 17 and been present until May 23.

Ben Lewis, founder of open source data platform PLATracker, said they thought it was unlikely that the H-6s would be deployed long-term on Woody Island or be permanently based there.

"The ability to cycle forces through the bases, especially higher level assets like the H-6, provides the PLA with a force protection mechanism," he said, referring to China's People's Liberation Army.

China's Southern Theatre Command, which covers the South China Sea, maintains two regiments of the bombers, according to the London-based International Institute of Strategic Studies.

The bombers are generally kept at heavily fortified bases on the Chinese mainland, where they would have more protection in a conflict from US attacks in conflict scenarios.

The US maintains jet fighter wings in Japan, including on its forward deployed aircraft carrier, and on Guam, which is also home to B-52s.

China claims sovereignty over nearly all the South China Sea, including areas claimed by Brunei, Indonesia, Malaysia, the Philippines, Taiwan and Vietnam.

A 2016 ruling by an international arbitral tribunal found Beijing's sweeping claims had no basis under international law, a decision China rejects.
