Why submarine missile tests matter

China recent missile test, conducted from a Type-094 nuclear-powered submarine, highlights the strategic role of its submarine fleet in the country’s nuclear framework.

Known for carrying nuclear-armed intercontinental ballistic missiles, these submarines are pivotal for China deterrent strategy, reflecting a focus on achieving a reliable second-strike capability. Located in Hainan, China SSBN operations are under intense scrutiny, as they are integral to countering potential adversaries.

For Beijing, the ability to operate these submarines undetected is crucial, particularly with an official stance that the nation would not initiate the use of nuclear weapons.

The U.S. and its allies actively monitor these submarines through naval assets, underwater sensors, and aircraft like the P-8 Poseidon, with surveillance efforts likely intensifying as China submarine capabilities expand.

A Pentagon 2022 report indicated that China initiated near-continuous deterrence patrols for its SSBNs, aligning it with practices established by other nuclear powers such as the U.S., Russia, France, and the UK. India’s own development of SSBNs further emphasizes the global strategic landscape.

A recent study by the Bulletin of the Atomic Scientists raised questions around the arming of these submarines. While no official U.S. confirmation exists, private commentary from officials suggests a possibility that nuclear weapons are involved in these patrols.

However, internal political dynamics, including President Xi Jinping’s dismissals within the military, cast doubt on whether such weapons would be readily available to the military.

Submarine-launched ballistic missiles (SLBMs) differ fundamentally from land-based missile systems, as they guarantee retaliation capability, essential for nuclear deterrence.

Beyond testing missile performance, the recent launch also served to evaluate command-and-control systems vital for maintaining secure communications while submarines remain undetected—a challenging but necessary component of nuclear operations.

Analysts, like Collin Koh from Singapore’s S. Rajaratnam School of International Studies, assert that the exercise was multifaceted, aimed at assessing both operational readiness and communication protocols alongside missile efficacy.

China nuclear triad

China nuclear triad is currently under scrutiny, particularly following a recent submarine missile launch that has yet to be precisely located or confirmed. Analysts emphasize the importance of the ability of China ballistic missile submarines (SSBNs) to operate undetected beyond its shores.

The existing Type-094 submarine is set to be replaced by a more advanced and quieter model, indicating ongoing enhancements in their naval capabilities.

To effectively target the continental United States, a submarine utilizing the advanced JL-3 missile must navigate from the South China Sea into the western Pacific ocean, a move that entails potential exposure to competing naval forces.

The JL-3 missile, believed to carry multiple warheads and showcased in a 2025 military parade, boasts an impressive range of 10,000 kilometers (approximately 6,214 miles).

Despite uncertainties surrounding the launch details, the Global Times newspaper has asserted that this event reflects China commitment to fortifying its nuclear triad.

This triad encompasses the capability to launch nuclear weapons from land, sea, and air, further enhancing China strategic posture. The editorial from Global Times suggests that such advancements are designed to dissuade external powers from pursuing military pressures or pre-emptive strikes aimed at China, thus significantly diminishing the likelihood of large-scale conflict in the region.

A key part of China nuclear modernization

China nuclear modernization has been marked by the advancement of its missile capabilities, specifically involving the Type-094 nuclear-powered ballistic missile submarines (SSBNs).

Although the exact vessel has not been confirmed by Beijing, regional defense experts suggest that recent missile launches were executed from these submarines.

Over the past decade, China has developed a comprehensive nuclear triad, enabling it to launch nuclear weapons from land, sea, and air.

The significance of the submarine component lies in its provision of a survivable retaliatory force, which is crucial if China land-based missile sites face destruction during any potential conflict. Recent U.S. defense assessments indicate that China has initiated near-continuous deterrence patrols with its SSBNs.

This action positions China alongside the United States, Russia, Britain, and France, all of which maintain at-sea nuclear capabilities, further emphasizing the evolving dynamics of global nuclear deterrence.

Challenges remain

Despite advancements, China submarine force encounters considerable operational challenges. To effectively utilize its advanced JL-3 submarine-launched missile against the continental United States, Chinese submarines would likely need to venture beyond the protective confines of the South China Sea into the broader Pacific Ocean.

This transition increases their vulnerability to detection by U.S. and allied anti-submarine operations. Military analysts indicate that American and allied navies actively monitor Chinese submarine movements through various means, including surveillance aircraft, underwater sensor networks, and naval patrols.

Moreover, China is in the process of developing a next-generation ballistic missile submarine designed to operate more quietly, potentially enhancing its capacity to evade detection.
