Chinese scientists discover how submarines could be geolocated by the bubbles created during their movement. What will this do to the future of stealth US submarines?
The latter could be the latest frontier to collapse after Chinese researchers have found a new way to detect the most advanced of US submarines and take away their advantage of stealth altogether.The US already uses multiple methods to minimize the detection of its submarines from advanced technologies. However, the approach of the Chinese plan could be extremely difficult to avoid.
Submarines cannot avoid these bubbles as their motion causes the water around the hull to move faster, reducing its potential energy. The potential energy is expressed as pressure and as it decreases, some of the water vaporizes to maintain the energy equilibrium. These might sound like extremely faint signals, but they are capable of traveling over large distances since they can penetrate the water and travel to the ionosphere before getting reflected back on Earth. Submarines already use these waves for communication and have sensors for their detection. It is only a matter of time before they are developed for geolocating the submarines of adversarial nations.
