Operation Hadal or Operation Leviathan (simplified Chinese: 蛟龙行动; traditional Chinese: 蛟龍行動; pinyin: Jiāolóng Xíngdòng; lit. 'Operation Jiaolong') is a 2025 action war film. It is a follow-up to the 2018 film Operation Red Sea. Differing from the previous film's above-water action set-pieces, this film is about a nuclear submarine and features mainly underwater action. A co-production between China and Hong Kong, the film was produced by Bona Film Group and directed by Dante Lam, and it stars Huang Xuan, Yu Shi, Zhang Hanyu, and Du Jiang.

It was released in China on 29 January 2025 (Chinese New Year). However, unlike Dante's previous two films, Operation Hadal was not a commercial success, as it faced criticisms over its weak character development, plot, and narrative and logical flaws.

Plot

In the near future, the Chinese Navy intercepts critical intelligence—an advanced super-submarine is secretly plotting a top-secret military operation against cities along China's southeastern coast. In response, China deploys its latest submarine, Longjing, to coordinate with the elite Jiaolong Squad in a high-stakes mission. The battlefield beneath the ocean is fraught with danger as the squad faces relentless traps, and the submarine engages in a series of intense confrontations with the enemy. As they maneuver through ambushes, they venture deep into the vast abyss filled with undersea volcanoes.
