Submarine Manufacturers — Who Builds Submarines?

The primary submarine builder for the US Navy and the company that built the first nuclear submarine, USS Nautilus. Electric Boat has delivered over 200 submarines and is currently building the next-generation Columbia-class ballistic missile submarines alongside Virginia-class attack submarines.

Newport News Shipbuilding partners with Electric Boat to produce Virginia-class submarines. As the only shipyard in the US capable of building nuclear aircraft carriers, Newport News is one of the most critical defense industrial facilities in the world.

The sole submarine builder for the Royal Navy. BAE Systems' Barrow-in-Furness shipyard has built every British submarine since 1886. Currently constructing the Dreadnought-class SSBNs that will carry the UK's nuclear deterrent and completing the Astute-class attack submarine program.

France's premier naval defense company with nearly 400 years of shipbuilding heritage. Naval Group builds nuclear submarines for the French Navy and exports the highly successful Scorpène-class conventional submarines to India, Brazil, Malaysia, and Chile.

The world's leading exporter of conventional submarines. TKMS pioneered Air-Independent Propulsion (AIP) using hydrogen fuel cells, allowing diesel-electric submarines to remain submerged for weeks without snorkeling. The Type 209 is one of the most widely exported submarine designs ever, serving 14 navies.

Russia's state-owned shipbuilding conglomerate, incorporating the legendary Sevmash shipyard (Severodvinsk) and Admiralty Shipyards (Saint Petersburg). Builds all Russian nuclear submarines at Sevmash, including the massive Typhoon class, and exports Kilo-class diesel-electric submarines to India, China, Vietnam, and Algeria.

One of two Japanese submarine builders (alongside Kawasaki Heavy Industries). MHI and KHI alternate submarine construction for the Japan Maritime Self-Defense Force. The Taigei class features lithium-ion batteries — a world first for a full-size submarine — providing superior underwater endurance without AIP systems.

Swedish submarine builder famous for the Gotland class — the first submarine with Stirling AIP engines. A Gotland-class submarine famously "sank" the USS Ronald Reagan aircraft carrier during exercises in 2005, demonstrating the threat posed by modern conventional submarines to even the most advanced navies.

The world's leading manufacturer of deep-diving personal submersibles. Triton built the DSV Limiting Factor — the only vehicle certified for repeated dives to full ocean depth (11,000m). Their range spans from compact yacht tenders to record-breaking exploration vehicles.

Dutch submersible manufacturer offering the widest range of personal and commercial submarines in the world. Their Cruise Sub line is designed for cruise ships, while the Super Yacht Sub series is popular with superyacht owners. The NEXUS is their flagship — a transparent-hulled submersible offering unobstructed views.

Specializes in luxury transparent-hulled submersibles with panoramic acrylic spheres. The Aurora-5 seats five passengers in a stunning transparent cockpit. Popular with resort operators and private yacht owners who want the ultimate underwater viewing experience.

Pioneer of "underwater flight" — submersibles that fly through the water using hydrofoil wings rather than traditional ballast systems. Founded by Graham Hawkes, one of the most innovative submarine designers in history. DeepFlight vehicles are positively buoyant, meaning they naturally float to the surface if power is lost.

Designs ultra-luxury submarine yachts that blur the line between yacht, submarine, and private island. The M5 concept is a 115-meter submersible superyacht. The Kokomo is a floating private island that can submerge. While few Migaloo designs have been built, they represent the extreme frontier of luxury submarine concepts.
