Navy to Deploy Electromagnetic Railgun Aboard JHSV: The U.S. Navy plans to install and test a prototype electromagnetic railgun aboard a joint high speed vessel in fiscal year 2016, the service announced today.
This test will mark the first time an electromagnetic railgun (EM railgun) has been demonstrated at sea, symbolizing a significant advance in naval combat.
EM railgun technology uses an electromagnetic force - known as the Lorenz Force - to rapidly accelerate and launch a projectile between two conductive rails. This guided projectile is launched at such high velocities that it can achieve greater ranges than conventional guns. It maintains enough kinetic energy that it doesn't require any kind of high explosive payload when
it reaches its target.
High-energy EM railguns are expected to be lethal and effective against multiple threats, including enemy warships, small boats, aircraft, missiles and land-based targets.
"The electromagnetic railgun represents an incredible new offensive capability for the U.S. Navy," said Rear Adm. Bryant Fuller, the Navy's chief engineer. "This capability will allow us to effectively counter a wide-range of threats at a relatively low cost, while keeping our ships and sailors safer by removing the need to carry as many high-explosive weapons."
EM railgun technology will complement current kinetic weapons currently onboard surface combatants and offer a few specific advantages. Against specific threats, the cost per engagement is orders of magnitude less expensive than comparable missile engagements. The
projectile itself is being designed to be common with some current powder guns, enabling the conservation of expensive missiles for use against more complex threats.
