Silent Submarines: How Fusion Tech Could Change the Game

USAThu Oct 23 2025

A British company is teaming up with a U.S. firm to develop a new way to power submarines.

The Partnership

  • Tokamak Energy is providing high-tech magnets to General Atomics.
  • These magnets are crucial for a new type of underwater propulsion system.
  • The system uses magnetic fields to move water instead of traditional propellers.

The Goal

  • To make submarines quieter and more efficient.
  • The new system has fewer moving parts, reducing noise and breakdowns.

The Technology

  • Tokamak Energy's magnets can create strong magnetic fields in a small space.
  • General Atomics is integrating these magnets into the overall system.
  • HRL Laboratories is developing the necessary electrodes.

The Collaboration

  • Brings together different strengths to overcome long-standing challenges.
  • The magnets and electrodes have been the main hurdles in making this technology viable.

The Vision

  • Tokamak Energy aims to deliver clean fusion energy but sees applications in other areas.
  • General Atomics is proud to strengthen U.S. leadership in innovation.
