Core Event
On Monday, July 10, 2026, a Chinese nuclear-powered ballistic-missile submarine launched a long-range missile with a dummy warhead into the southern Pacific Ocean. The launch was carried out from one of China’s six Type-094 strategic missile submarines (SSBNs). The missile, believed to be the JL-3 SLBM, has an estimated range of 10,000 km (6,214 miles). Chinese state media called the exercise a “routine” military drill that was not directed at any specific target or country.
Background & Context
China’s SSBN fleet, based out of Hainan Island, has been conducting near-continuous deterrence patrols since at least 2022, according to a Pentagon report. The test marks the first submarine-based long-range launch since a ground-based test in September 2024 and only the third open-ocean SLBM launch since the 1980 launch. The JL-3 missile was showcased in a Beijing parade in September 2025. Analysts note that submarine launches allow China to gather data on full-trajectory performance and command-and-control procedures that lofted domestic tests cannot provide.
Data & Statistics
- Six Type-094 SSBNs constitute China’s current sea-based leg of its nuclear triad.
- The JL-3’s range of 10,000 km would enable strikes on Guam, Hawaii, or the continental United States if the submarine can transit beyond the South China Sea into the western Pacific.
- A study by the Bulletin of the Atomic Scientists highlighted that U.S. officials have privately indicated belief that Chinese SSBNs may already be armed with nuclear warheads, though no public confirmation exists.
Why It Matters
The test demonstrates progress toward a survivable “second-strike” capability, a cornerstone of nuclear deterrence. If Chinese SSBNs can operate undetected, they could retaliate even after a successful first-strike on land-based assets, complicating strategic calculations for the United States and its allies. The ability to command and communicate with submerged submarines without revealing their position remains a technically demanding challenge that the test sought to evaluate.
Official Statements & Responses
- The U.S. described the missile as an intercontinental ballistic missile that landed in the southern Pacific and expressed concern over limited advance notification.
- Japan, Australia, New Zealand and Taiwan also voiced concern, citing regional security implications.
- China rejected the criticism, insisting the exercise complied with international law and was intended solely to safeguard national security and strategic stability.
Criticism & Opposition
Regional powers view the test as a signal of Beijing’s willingness to counter increasing U.S. missile-defense deployments and new defense pacts, such as the Australia-Fiji mutual-defense treaty signed hours before the launch. Analysts argue that the timing may reflect Beijing’s displeasure with expanding U.S. defense architecture in the Indo-Pacific.
Conflicting Reports & Gaps
U.S. officials have privately suggested Chinese SSBNs may already carry nuclear warheads, yet no public confirmation exists. The exact launch location and the specific missile variant used have not been independently verified.

- “This aspect is certainly something that would have been very much evaluated, besides looking at the actual technical capabilities of the missile and submarine,” — Collin Koh, Security Scholar, S. Rajaratnam School of International Studies
- “This will compel external powers and their followers to abandon attempts aimed at forcing Chinese concessions through maximum military pressure or pre-emptive strikes, thereby fundamentally reducing the risk of large-scale conflict...,” — Global Times editorial
- “routine” military drill that was not directed at a specific target or country. — Chinese state media and officials
- “China rejected the criticism, insisting the exercise complied with international law and was intended solely to safeguard national security and strategic stability.” — Chinese government statement
What’s Next
U.S. and allied navies are expected to increase anti-submarine surveillance in the western Pacific, while China continues development of a quieter next-generation ballistic-missile submarine to enhance its undetectable operating capability.
