Submarines — Who Builds & Supplies the Fleet

Only a few countries can build a nuclear submarine at all. That scarcity is the whole point.

Submarines are among the most complex machines anyone builds, and the nuclear ones can be built by only a handful of nations. The map draws each class to scale, from Russia's Typhoon down to Germany's Type 214, then breaks each boat into the firms behind it.

US Ohio, Columbia, Virginia (General Dynamics Electric Boat, Huntington Ingalls, BWXT reactors, Lockheed's Trident). UK Vanguard and Astute (BAE, Rolls-Royce). France's Naval Group. Plus the Russian, Chinese, Indian, Japanese, Australian and Korean programs. Shared suppliers — Lockheed's Trident across US and UK boomers, Thales sonar across several navies — light up across the fleet.

Most of these contractors are public. Submarine work is the longest-duration, least contestable backlog in defense. That is the moat.
