Lithium-ion Batteries powered Submarines, UUW and torpedoes have enhanced Stealth, endurance, speed and reliability

Batteries have been used on underwater applications for more than a century, for instance, lead-acid batteries have been used in conventionally powered submarines since the end of the 19th century. Since World War II, submarines have used lead acid batteries. Lead acid batteries are heavy, but they’re also a proven …

Countries developing new, longer range and lethal heavyweight torpedos fired by ultraquiet submarines to kill adversaries

Torpedoes are self-propelled guided projectiles that operate underwater and are designed to detonate on contact or in proximity to a target. For the U.S. Navy, the modern torpedo enables submarines to defeat surface and undersea threats and gives surface ships and aircraft the means to reach beneath the surface and …
