Navy Debuts New Railgun That Launches Shells at Mach 7

Jeremiah Cornelius writes: "The U.S. Navy's new railgun technology, developed by General Atomics, uses the Lorentz force in a type of linear, electric motor to hurl a 23-pound projectile at speeds exceeding Mach 7 — in excess of 5,000 mph. The weapon has a range of 100 miles and doesn't require explosive warheads. 'The electromagnetic railgun represents an incredible new offensive capability for the U.S. Navy,' says 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.' Sea trials begin aboard an experimental Navy catamaran, the USNS Millinocket, in 2016."

    according to the experts at yahoo answers, there isn't recoil in the traditional sense, but there is recoil because physics and also it somehow forms babby.

    F=MA. M = big, A = very fast, therefore F = big very fast!

    And that, ladies and gentlemen, is a demonstration of what we science nerds like to call 'simple science for senators". The amazing thing about it is that you can actually get billions of dollars in funding using this simplified approach when brilliantly researched and written scientific papers fail miserably. Go figure!?!?
