Ever wondered how submarines actually work beneath the waves? In this Knowledge Hub video, we dive deep into the world of submarine engineering and explain the incredible technology that allows these massive steel vessels to travel silently underwater for months at a time.

We’ll explore how ballast tanks control buoyancy, how submarines can dive hundreds of meters below the ocean’s surface, and how they withstand the crushing pressure of the deep sea with specially designed pressure hulls. Learn how different propulsion systems, from diesel-electric submarines to advanced nuclear-powered submarines, give these vessels endurance and stealth unmatched by other ships.

We’ll also explain how submarines avoid detection with sonar systems, anechoic tiles, and quiet propellers, as well as how they navigate without GPS using inertial navigation systems and sonar mapping. Discover how submarines use thermoclines to hide, how they generate oxygen and remove carbon dioxide to keep crews alive, and how life on board is sustained for months at a time.

Submarines aren’t just military machines, they’re also vital tools for ocean exploration, scientific research, and strategic deterrence. From stealthy nuclear attack subs to record-breaking research craft like the Trieste, these underwater giants represent some of the most advanced technology ever built.
