For more than three years now, I've been tracking the U.S. Navy's progress toward building a working electromagnetic railgun prototype — a Mach 6 cannon reputedly capable of striking targets 110 miles away with pinpoint accuracy.
Each railgun projectile would cost about $25,000 to produce — and if you're keeping track, then yes, success on the railgun project would yield a weapon boasting nearly twice the 67-mile range of Boeing's (NYSE:BA) Harpoon II missile but costing just 1/48th the Boeing missile's $1.2 million cost.
