JL-3

The missile that completes China's triad at sea — the JL-3 ("Giant Wave 3") is China's third-generation submarine-launched ballistic missile: solid-fueled, roughly 10,000 kilometers in estimated range, likely MIRV-capable, and now fielded aboard the six Type 094 Jin-class submarines rather than waiting for their successor. The Pentagon's 2025 China report says it "ranges most of the continental United States"; the Federation of American Scientists notes that claim only works from China's shallow home seas, not the South China Sea bastion the boats actually patrol. Beijing paraded it for the first time in September 2025 — and has never announced a single test.

Overview

The JL-3 (JuLang-3; NATO CSS-N-20) is the weapon that turns China's sea-based deterrent from a regional gesture into an intercontinental fact. Its predecessor, the JL-2, could not reach the continental United States from Chinese home waters, which left the Type 094 Jin-class fleet strategically hobbled for a decade. The JL-3 adds an estimated 1,000–3,000 km of reach — the figures span "more than 9,000 km" (DIA, 2019) to ~10,000+ km (Pentagon) to unconfirmed analyst highs of 12,000 — and is assessed as likely MIRV-capable, though no warhead count is verified. Deployment came earlier and lower-tech than Washington expected: rather than debuting on the next-generation Type 096, the missile was back-fitted onto the six existing Jin-class boats homeported at Hainan, a fact STRATCOM commander Gen. Anthony Cotton confirmed to Congress in March 2023. The December 2025 China Military Power Report calls the JL-3 fielded and says it "ranges most of the continental United States" — with the important FAS caveat that CONUS coverage requires launching from the Bohai or Yellow Seas, since even 10,000 km falls short from the South China Sea bastion. Its first public display came on 3 September 2025, rolling through Tiananmen alongside the air-launched JL-1 and the DF-61 in the first parade to show all three legs of China's triad. Every number in this file is an estimate: China has never announced a JL-3 test, disclosed a specification, or confirmed a deployment.

Development

The JL-3 surfaced the way Chinese strategic weapons do — through American disclosures. The first flight test, on 24 November 2018 in the Bohai Sea from a modified conventionally-powered trials submarine, was reported by US-government sources and assessed by CSIS Missile Threat as verifying the cold-ejection system, per The Diplomat. A probable second test followed on 2 June 2019 — sky phenomena over Shandong, assessed by Janes as a Bohai Bay launch toward western impact ranges — with a further reported test that December. The fielding story then ran ahead of expectations. The Pentagon's 2022 report said the JL-3's range would let the PLAN target the continental US "from the safety of 'bastion' waters" and assessed near-continuous deterrence patrols by the six Jin-class boats from 2021; that November the Pacific Fleet commander said all deployed JL-2s had been replaced by JL-3s, and in March 2023 STRATCOM's Gen. Cotton told Congress the Jin fleet was "now being equipped" with the missile, per the Arms Control Association — deployment on the Type 094 rather than the future Type 096, years early. The 2024 CMPR still described boats as "upgrading to" the JL-3 (a conversion-status conflict FAS flags), before the December 2025 CMPR settled on "fielded… ranges most of the continental United States." On 3 September 2025 the JL-3 was displayed publicly for the first time at the Victory Day parade, in the nuclear formation with the JL-1 air-launched missile and DF-61, per the Federation of American Scientists.
