TRITON 7500/3

The world’s deepest diving three-person acrylic submersible

Triton 7500/3 submersible in electric green

Using proprietary technology, developed in collaboration with Triton’s exclusive acrylic manufacturing partners, the TRITON 7500/3 is the world’s deepest diving, three-person acrylic hulled submersible.

Capable of diving over 1.4 miles to the great depths of the ocean’s Bathypelagic zone, the TRITON 7500 series represents a new breed of submersible. Observation is fundamental to scientific enquiry and the fully transparent, acrylic pressure hull creates the potential for more excitement, new adventures and even greater versatility.

Featuring proprietary systems developed for and proven during record-setting operation of the Triton 36000/2, the Triton 7500/3 represents a unique opportunity to acquire a series-built submersible capable of safe, reliable and repeatable operation at extreme depth.

The versatile lift points on the TRITON 7500/3 have been configured for launch and recovery using either tender-style davits found in yacht garages, or deck-mounted crane and A-Frames.

Welcome to the Bathypelagic Zone

The TRITON 7500/3 grants scientists, researchers and explorers access to the Bathypelagic Zone.

It combines technologies developed on the record-breaking TRITON 36000/2 and marries them to one of only two acrylic hulls on Earth certified to such depths. The result is a high-performing, incredibly reliable ultra-deep diving submersible which offers wrap-around 360 degree views.

Unique Exploration

Until now manned access to depths in excess of 1,000m in the bathypelagic zone has been limited to a handful of experimental and state funded submersibles. With the TRITON 7500/3 a doorway to the deep opens, permitting marine researchers, documentary filmmakers and archeologists to pioneer exploration of wide swathes of the Earth’s oceans for the very first time.

As owner of a TRITON 7500/3 opportunity exists to become the first human to undertake an uncountable diversity of unique experiences; will you be the first person in history to witness a sperm whale and giant squid locked in mortal combat in their natural habitat?

Participation & Preservation

In 2018 the world’s oldest perfectly preserved shipwreck was discovered lying at a depth of 2,000m in the Black Sea off the coast of Bulgaria. Due to a lack of oxygen at those depths, the ancient Greek trading ship has lain undisturbed, with masts, rudders, cargo and rowing benches all perfectly preserved for an estimated 2,400-years.

Containing an unparalleled archive of data, which will contribute significantly to our understanding of history, this 75’ vessel is just one of many archeological treasure troves accessible to the owner of a TRITON 7500/3. Providing the assets for archaeological experts and participating in the study of such wrecks is the kind of unique experience and legacy project available only to owners of TRITON 7500/3 submersibles.


In a zone of the ocean where the majority of occupants have evolved without ever encountering sunlight, the darkness is punctuated by marine life that create their own incredible pyrotechnic display. Employing bioluminescence to attract prey, mates and even communicate, owners of TRITON 7500/3 have the rare opportunity to witness a spellbinding light-show like no other.

Proving the platform of choice for some of the most accomplished documentary film-makers to grace the silver screen, owners of the TRITON 7500/3 can write their own page in history by documenting, sharing and providing an insight into one of the planet’s last unexplored frontiers.
