An Inventory Built On Operational Experience

Silvercrest Submarines is a UK-based submarine operator, broker, and engineering company with over three decades of active involvement in the submarine and submersible sector. Unlike manufacturers who supply equipment they have never operated, or brokers who list vessels they have never dived, Silvercrest Submarines brings genuine operator knowledge to every transaction. That matters when the asset in question is a pressure vessel designed to carry passengers or crew beneath the ocean surface.

The submarines and submersibles listed here represent a carefully sourced inventory spanning passenger capacities from a single occupant to 48 passengers, and operating depths from the recreational range of 40 metres to the extreme deep of 500 metres (1,640 feet) and beyond. New builds, refurbished platforms, and operational used vessels are all represented.

What Types of Submarine Are Available?

Tourist Submarines

The largest category in the Silvercrest Submarines inventory, tourist submarines range from 10-passenger DNV-certified vessels suitable for resort and island operations through to large 46 and 48-passenger third-generation platforms proven in commercial tourist operations. New-build options are available for operators looking to commission a vessel to their own specification. Silvercrest Submarines has direct operational experience in tourist submarine programmes.

Luxury Yacht Submarines

Designed for integration with superyachts and private vessels, this category includes compact 2 and 3-person submersibles,  alongside the more capacious Luxury Leisure Submarine at 8–10 passengers. Yacht submarines require particular attention to launch and recovery systems, deck space, and vessel compatibility; Silvercrest Submarines is well-placed to advise on integration requirements based on direct experience.

Research and Filming Submarines

A broad category covering platforms used by scientific institutions, film production companies, and documentary makers. Many submersibles all appear in this section, covering depth ratings from 85 metres to 500 metres (1,640 feet) and  deeper, with a range of viewport, lighting, and payload configurations suited to scientific and media work. Silvercrest Submarines has an established track record in underwater filming operations, having supported international broadcasters including the BBC, Channel 4, and the Discovery Channel.

Commercial Work Submarines & ROVs

This category includes professional-grade platforms designed for pipeline inspection, subsea construction support, and diver lockout operations.. Buyers in this category are typically operators with specific project requirements; Silvercrest Submarines can provide detailed technical consultancy alongside any sale.

Military and Special Forces Submarines

The Special Forces SDV is a hybrid surface-and-submerged delivery vehicle originally designed for military applications and adapted for civilian and security use. Enquiries in this category are handled with appropriate discretion and are subject to export licensing requirements where applicable.

Semi-Submersibles and Wet Submersibles

Including the SportSub and ResortSub wet submersibles — open-cockpit platforms rated to 40 metres and deployable without a support crane — and the Mini Semi-Submersible, this category covers a range of applications from resort and lagoon operations to personal leisure and underwater photography.

Atmospheric Diving Suits (ADS)

The Spider ADS and Wrangler ADS provide one-atmosphere diving capability to 2,000 feet (610 metres) and 1,200 feet (366 metres) respectively. These are highly specialised systems for deep commercial and inspection work, allowing a single operator to work at depth without the saturation diving infrastructure typically required.

Personal Submarines

The Kittredge K-250 and K-350 represent individual ownership of a genuine one-atmosphere submarine — the K-250 rated to 80 metres for a single occupant, the K-350 to 100 metres for two. Both are road-transportable and can be launched from a suitable vessel or jetty without specialist handling equipment.

Buying a Submarine: What to Consider

Purchasing a submarine or submersible is a significant capital investment with operational, regulatory, and logistical dimensions that differ substantially from other marine asset purchases. Prospective buyers should consider the following before proceeding.

Classification and Certification

Most commercially operated submarines require classification by a recognised classification society — Lloyd's Register, Det Norske Veritas (DNV), Bureau Veritas, Germanischer Lloyd, or the American Bureau of Shipping (ABS), depending on the operating jurisdiction and passenger numbers. Classification involves periodic survey and defines the permitted operating envelope. Silvercrest Submarines has experience working with all of the major classification bodies and can advise on certification pathways for both new purchases and vessels requiring recertification.

Operational Support

A submarine is not a standalone asset. Effective operations typically require a support vessel, trained pilots and technicians, maintenance protocols, and in many cases a shore-based support team. Silvercrest Submarines offers pilot training, crew supply, operational consultancy, and engineering support services to buyers who require them.

Transport and Logistics

Most of the submarines in the Silvercrest Submarines inventory are designed for global deployment and have been transported by road and sea to locations across the Mediterranean, Indian Ocean, Pacific, Caribbean, and Arctic regions. Silvercrest Submarines can advise on transport logistics and has direct experience of international submarine mobilisation.

Pricing

All submarines and submersibles are priced on application. Prices vary substantially with age, condition, classification status, depth rating, passenger capacity, and the complexity of any associated support package. Silvercrest Submarines does not publish list prices online; please contact us directly for a detailed quotation and, where relevant, a specification review.

Submarines For Charter

Several vessels in the inventory are available for charter rather than outright sale. Charter arrangements can be structured as short-term or long-term hire, with or without experienced crew, and with varying levels of logistical and operational support.

Charter submarines are particularly suited to film and documentary production, scientific expedition work, and corporate or event-based applications. Use the availability filter above to view charter-only listings, or contact Silvercrest Submarines to discuss a bespoke charter arrangement.
