65m undersea superyacht Phoenix 1000 is a personal luxury submarine built by US Submarines. Submarine yacht Phoenix 1000 is the single largest private undersea vehicle ever built, and probably one of the most important personal transportation devices of the century.

213´ luxury submarine yacht Phoenix 1000 has more than ample space. The total interior area of the submarine is in excess of 460 square meters (5000 square feet). The significant volume, coupled with very large acrylic viewports, and the potential for relatively large open spaces, results in a vehicle as luxurious as the finest of motor yachts.

Clearly, underwater super yacht Phoenix 1000 provides its owner with substantially more capability than a simple yacht – the opportunity to explore the depths of the world’s oceans in perfect comfort and safety. The Phoenix 1000 yacht is capable of making trans-Atlantic crossings at 16 knots yet can dive along the route and explore the continental margins of some of the most fascinating waters on earth.

And unlike surface yachts, when the water gets rough, the submarine can submerge into a perfectly smooth and quiet environment, continuing on toward its destination, providing a ride unsurpassed in quality-unequaled by the finest motor coach or the most luxurious executive aircraft.

At 65-meters (213 feet) in overall length, and with a beam in excess of 8 meters (26 feet), the Phoenix 1000 is a vehicle of formidable size. Yet despite its 1500-ton displacement, the submarine is quite streamlined. Given the significant waterplane area and ample internal volume, which allows for greater battery storage, the Phoenix 1000 yacht will out-perform smaller counterparts in surface speed, submerged speed and submerged endurance.

The large pressure hull diameter allows for very large acrylic viewports, making the undersea viewing capability truly extraordinary. The interior space, with the noted absence of structural bulkheads, provides for tremendous versatility in interior layout and space planning. And finally, the Phoenix 1000’s large size coupled with its integrated roll stabilization system makes surface transit quite comfortable in all but the worst conditions.

Flying Bridge

The uppermost level of the vessel is the flying bridge. This area is similar to its equivalent area on most yachts, with the exception of the fact that the materials selected are subject to immersion in water. Ample space exists for lounging, and cushions may be brought up from the area below. The flying bridge also houses the pressure-compensated radar radome, GPS antennae and satellite communications radome, as well as radio aerials, running lights, etc. A remote steering station is also available.

Deck Saloon

Immediately below the flying bridge and accessible through a large hydraulically operated hatch and a stairway, is the deck saloon. As proposed, this area would be composed of structural acrylic cylindrical sections 2.1 meters (7′) in diameter and 20 centimeters (8″) in thickness. The overall length of the deck saloon pressure hull would be 12 meters.

The deck saloon would have a comfortably appointed interior and would boast an incredible view for observation, both on the surface and when submerged. By fitting transparent sections into the deck of the flying bridge, a view above can be enjoyed as well.

In the forward portion of the saloon is the surface bridge. This area contains all the necessary control, monitoring and navigation equipment to operate the submarine in the surfaced condition. The captain has a hemispherical sector acrylic viewport immediately in front, with the transparent cylindrical walls to either side.

The aft portion of the saloon has a large acrylic window, providing a view astern that also acts as a large hydraulically operated hatch. A small automobile could be kept in the aft section if desired.


The superstructure itself is composed principally of aluminum (or FRP if the owner prefers), and it houses the deck saloon pressure vessel and also provides the structural base for the flying bridge. There is a large degree of latitude possible with regard to the styling of the structure, with the caveat that its hydrodynamic efficiency will have a significant effect on the submerged speed of the submarine.

Aft of the deck saloon is a covered space that can be either fully or partially enclosed. The greater the degree of closure to the after portion of the structure, the less turbulence and the more hydromdynamic efficiency. Hydraulically actuated after doors could be designed to open, allowing fresh air to circulate. The area would be excellent for covered, informal, deck-level dining.

Docking Minisub

Aft of the superstructure, or optionally, above the control cabin on the bow, is an area for a docking minisub. Utilizing a special docking collar, this vehicle is capable of leaving the Phoenix 1000 superyacht while submerged and making excursions down to 610 meters (2000 feet). With both top and bottom hatches, the minisub could also bring passengers from the surface to the submarine lying at depth. The minisub could be designed to hold between two and eight passengers, depending upon the owner’s preferences. Additionally, in the unlikely event of an emergency at depth, the minisub could be used to take passengers and crew to the surface.

Forward Control Room

The forward control room is entered from the main deck through a watertight, pressure-proof door. The control room has a 2.4 meter (8′) diameter hemispherical sector acrylic viewport forward and three 1.8 meter (6′) diameter viewports on either side, with the foremost pair angled slightly forward.

The control room contains all of the control and navigation equipment necessary to operate the submarine while submerged. The 8 meter x 4 meter (26′ x 13′) area contains sufficient space to fit comfortable lounge chairs for passenger observation while underway.

Main Passenger Areas

The main passenger area consists of two decks, each 31 meters (102′) long and 6 meters (20′) wide. The upper deck is accessed from one of two hatches, either from the deck saloon or from a hatch to the after portion of the superstructure. Two stairways, one in the center of the deck, the other in the after section, lead to the lower deck.

The upper deck is intended to provide space for an engineering workstation, a switch and contactor room, crew cabins and mess, as well as the galley. The forward portion, which ends at a bulkhead, is designed as a room of the owner’s choosing.

The main deck is situated such that the forward portion, with eight 1.8 meter (6′) diameter acrylic windows, contains the living and dining areas, while the section aft of the beam houses the owner’s stateroom and guest cabins. Five viewports, 90 centimeters (35″) in diameter, are situated on both port and starboard sides.

Below the passenger area is the battery compartment and bilge. A narrow manway allows access through the compartment for battery maintenance.

Engine Room

The engine room is accessed through doors at the after portion of both passenger decks. The space contains the majority of the equipment necessary for the submarine’s operation, including the main diesels, motor generators, drive systems, air compressors, hydraulic aggregates and life support systems. The upper level of the engine space provides access to the minisub, and in the stern section, to a diver lock-out chamber. The bottom level allows maintenance of the main engines and related components.

Diver Lock-out Chamber

A spherical diver lock-out chamber, 2.4 meters (8′) in diameter is fitted above the shafts and attached to the aftermost section of the pressure hull. The chamber allows a diver to enter or exit the submarine from the area between the shafts at depths of up to 45 meters (150′). The chamber can be fitted with decompression capability if required.
