Triton 650: 2 Person, 1 Atmosphere Sub

The Triton 650 is U.S. Submarines' latest design and represents an advanced, light weight minimum volume 2-person configuration engineered specifically for deployment from megayachts. With an overall height of 1.8 meters and an overall length of only 3.8 meters the Triton will fit on many mid-level boat decks, and at 2.7 tons it can often be launched with the existing davit systems.

Stability & Freeboard
Vehicles built by U.S. Submarines are unique in that they are the only small submersibles available that have excellent surface stability and also meet the ABS freeboard requirement of .77 meters between the water's surface and the hatch. These factors are critical in the enjoyment of a leisure submersible. Other commercial manufacturers build submersible where the passengers or scientists must embark and disembark while on the deck of the support ship. This reduces operating flexibility and requires an expensive manned launch and recovery system and does not provide the occupants a safe exit from the submarine while it is on the surface.

Learning to Be a Pilot
U.S. Submarines provides piloting and maintenance training to the owner or crew at no additional cost. Triton has been designed to be easy to pilot, with intuitive joystick controls and a computer based monitoring system. The thrill or piloting your own deep submersible is a rare and rewarding experience.

  • The Triton 650 can be trailered behind a truck or SUV or shipped in a standard container.
  • The Triton design provides for excellent visibility and high levels of comfort with luxury leather seating and full air conditioning.
  • No complex maintenance is required.
  • The Triton 650 has proven reliable in diverse marine conditions.
  • U.S. Submarines only use components proven effective in subsea applications.
