For the first time since its induction in 2007, the People’s Liberation Army (PLA) has officially released detailed specifications of its Type 094 nuclear-powered ballistic missile submarine. The rare disclosure occurred during the PLA Navy’s 76th anniversary celebrations, as part of a public open day event.
According to information displayed at the event, the Type 094—also known as the Jin-class—has a submerged displacement of 11,000 tonnes, a maximum speed of 30 knots, and an operational diving depth of 400 metres. These figures significantly exceed previous external estimates, which had placed the submarine’s displacement at 9,000 tonnes, top speed at 20 knots, and depth capability at 300 metres.
The submarine is approximately 135 metres in length, 13 metres wide, and has a surface displacement of 8,000 tonnes. It is armed with JL-2 ballistic missiles capable of carrying nuclear warheads over a range of approximately 7,000 kilometers, enabling China to project credible sea-based nuclear deterrence.

While the Type 094 had been visually confirmed during naval reviews in 2018 and 2019, this marks the first instance of China’s military releasing detailed performance data to the public. Analysts see the move as part of a broader effort by the PLA to showcase its growing naval capabilities and strategic deterrence power.
The reveal comes amid heightened regional tensions and growing military transparency in response to international scrutiny. The upgraded specifications also suggest improvements in stealth and underwater endurance, likely aimed at countering the strategic advantages held by U.S. and allied naval forces in the Indo-Pacific.
