This Is How America's Nuclear-Submarine get Resupplied at Sea



The U.S. Navy just tested a new delivery system for supplying submarines while underway at sea—by drone. In a video released by the Navy, a large quadcopter-type drone seen hovering above the deck of a ballistic-missile submarine. A small payload, not much larger than a small backpack, dangled from a line attached to the drone. Despite the gentle rolling of the submarine’s hull, the drone successfully made the drop. The video description read:

“An unmanned aerial vehicle delivers a payload to the Ohio-class ballistic-missile submarine USS Henry M. Jackson (SSBN-730) around the Hawaiian Islands. Underway replenishment sustains the fleet anywhere/anytime. This event was designed to test and evaluate the tactics, techniques, and procedures of U.S. Strategic Command’s expeditionary logistics and enhance the overall readiness of our strategic forces.”

Which are the best submarines in the world? Which are the most powerful submarines in the world? The stealthy and deadly attack submarine- every seaman’s worst nightmare since World War I.

These are the weapons navies fear the most, and despite investing billions of dollars into locating, tracking, and targeting these underwater assassins, the navies of the world are still largely at the mercy of these silent machines. Hello and welcome to another episode of The Infographics Show- today we’re taking a look at the top ten underwater machines in Top Ten Attack Submarines in the World.

Why the U.S Built Only 3 of the Deadliest Submarines Ever, Like The F-22 of Submarines



The ‘F-22’ of Submarines: Why America Built Only 3 of the Deadliest Submarines Ever

In the late 1980s, the U.S. Navy was faced with a crisis. In 1980, the Soviet Union had received information from the Walker family spy ring that the Navy could track its submarines through excessive propeller noise. As a result, the Soviet Union went looking for advanced Western machinery to make better propellers. In 1981, the Japanese company Toshiba sold propeller milling machinery—now relatively common nine-axis CNC milling machines—to the Soviet Union via the Norwegian Kongsberg corporation.

By the mid 1980s, the Soviet Union’s new machinery began to make itself felt. The new Akula-class submarines had a “ steep drop in broadband acoustic noise profiles ”. One government source told the Los Angeles Times , “the submarines started to get silent only after the Toshiba stuff went in.” On top of running silent, the Akula class could dive to depths of up to two thousand feet—while the U.S. Navy’s frontline submarines, the Los Angeles class, could dive to only 650 feet.

To combat the threat of the Akula class, the U.S. Navy responded with the Seawolf class of nuclear attack submarines. The Seawolf submarines were designed with HY-100 steel alloy hulls two inches thick , the better to withstand the pressures of deep diving. HY-100 steel is roughly 20 percent stronger than the HY-80 used in the Los Angeles class. As a result, the submarines are capable of diving to depths of up to two thousand feet, and crush depth estimates run from 2,400 to 3,000 feet.
