A new study says emerging submarine detection technologies, computer processing power and platforms such as underwater drones could quickly erode the U.S. military’s global undersea dominance and ability to operate in high-threat areas such as locations near enemy coastlines. The U.S. military relies upon submarines and undersea technological superiority for critical underwater intelligence, reconnaissance and surveillance […]

The Navy is getting ready to take the next step in its ongoing competition to build a new amphibious assault ship for the service, officials said. Called the LX( R ), the new amphib will replace the Navy’s existing fleet of LSD 41/49 dock landing ships in the 2020s and 2030s, said Navy spokesman Matthew Leonard. […]

The Navy has begun to build a new fleet of air-cushioned Landing Craft Air Cushions — ship-to-shore amphibious connector vehicles able to move sailors, Marines, equipment and gear across the ocean, service officials said. The Navy’s 72 LCACs, in service for decades since the 80s, can transport up to 60-tons, reach speed of 36-knots and travel ranges […]

The Navy is using a special, hi-tech side-scanning sonar system to assist Indonesian authorities searching for debris and bodies from Air Asia flight QZ8501, the passenger jet which recently crashed into the Java Sea. Called the Tow Fish side-scan sonar system, the technology uses sonar to map the ocean floor and search for debris and […]

The Navy is outfitting a prototype Virginia-class attack submarine platform with a series of upgrades designed to improve sonar detection and make boats less detectable and more stealthy. The work includes the addition of a large vertical array, special coating materials for the exterior of the submarine and special noise-reduction technologies for the engine room, […]
