Synthetic Aperture Sonar on Unmanned underwater vehicle (UUVs) and AUVs is transforming Mine Countermeasures and Undersea Warfare

SOund Navigation And Ranging or SONAR is a technique of distance measuring between detector and an object base on sound reflection. The distance can be calculated from propagation time and speed of sound in specific mediums. For military, Sonars are the eyes and ears of ships or submarines in water …

China militarizing deep-ocean as another domain of warfare by building deep sea Naval base in South China Sea and deep sea “space station.”

Like the British Royal Navy more than a century before it, the U.S. Navy has a command of the sea that affords the United States unrivaled international influence.  By its use of the sea, which covers nearly three-quarters of the earth, a navy can do things that land-based forces cannot. …

Militaries race for Unmanned and Autonomous underwater vehicle (UUV & AUV) to dominate the world’s oceans

UUVs—submersible unmanned vehicles—are divided into two categories: remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs). ROVs are controlled and powered by a person or crew on either land or neighboring craft via an umbilical or using remote control. The cables enable maneuverability of the ROV, allowing it to travel …

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 …

Countries led by Russia, US and China employing Supercavitation technologies to develop supersonic Submarines, Vessels, and Torpedoes

One of the biggest problems with trying to get torpedos to travel faster is the fact that water is a thousand more times dense than air, so in order to overcome that resistance researchers have had to try a variety of different techniques. One of the  phenomenon called supercavitation uses …

Raytheon’s Excalibur is all weather smart artillery that triples the range and can strike moving targets with high precision

The Excalibur smart artillery shell has a ruggedized Global Positioning System (GPS) satellite navigation receiver and uses satellite signals to help guide itself to its intended targets. It first was fielded in Iraq in 2007 for urban or complex-terrain engagements in which collateral damage must be kept to a minimum. …

Blue-Green laser critical technology for anti-submarine warfare and Network Centric Operations

A reliable long-distance and high-speed underwater communication link plays an important role in the undersea exploration and data collection. At present, the most widely used underwater communication method is still dominated by underwater acoustic communication. Although it can reach the transmission distance of several kilometers and more, the data rate …

US Navy’s Autonomous surface vehicle, ACTUV developed to track quiet diesel-electric submarines, successfully navigated autonomously

China, Russia and North Korea are looking to develop their submarine fleets . Russia is seeking to further bolster its sub-surface capabilities, with new generations of conventional and nuclear propulsion submarines, which promise to be significantly more difficult to detect and track for western naval forces. This includes the Yasen, …
