fifty times deeper than the glass‑bottom tourist subs that stop at 20.

The project is led by the China Ship Scientific Research Center in Wuxi, Jiangsu Province. Structural design is complete,
and a prototype is expected before the end of 2026. The plan is to have commercial operations running before 2030.
Capacity is set at four people — three passengers and one operator — inside a pressure hull designed to withstand forces a hundred times greater than those at the surface.
The most difficult feature is the panoramic viewport.
At 1,000 meters, water pressure is immense, and transparent materials must resist deformation while still offering clarity.
Engineers are working with advanced composites and layered structures to balance strength with visibility.
It’s a challenge that has stalled similar projects elsewhere.
China has already proven its deep‑sea credentials.
Scientific submersibles like Fendouzhe and Shenhai Yongshi have reached depths of 10,000 meters, carrying researchers into the hadal zone.
But those craft are small, cramped, and built for science. Tourism requires something different: comfort, safety, and a view worth the ticket price.
The choice of 1,000 meters is deliberate. It’s far deeper than existing tourist subs, but conservative compared to the Titan submersible that imploded in 2023 at nearly 3,800 meters.
By staying within a safer pressure range, designers aim to reduce risk while still offering passengers a glimpse of the ocean’s “Midnight Zone”
— a layer where sunlight never penetrates and bioluminescent life thrives.
Past attempts at tourist subs in China were modest.
The Huandao Jiaolong 1 and 2 carried seven passengers to 40 meters, but operations were suspended due to regulatory concerns.
This new craft is intended to meet stricter safety standards and international certification, opening the door to partnerships with cruise lines and high‑end tour operators.
Interest is already building. Oceanographic researchers see potential for dual use — tourism trips by day, scientific observation at night.
Cruise companies are exploring how submersible excursions could add value to itineraries.
For passengers, the appeal is simple: a chance to descend into a world few humans have ever seen.
The perspective to sit with is this: by 2030, stepping into a capsule with a panoramic window
and sinking into the dark ocean could be as routine as booking a shore excursion.
If China succeeds, deep‑sea tourism will no longer be a curiosity. It will be an industry.
