That electromagnetic railgun is cool and all, but it's not the Navy's only wargadget in progress. Apparently, the Armed Forces branch has also been working tirelessly to improve its ship-mounted lasers and autonomous helicopters since we'd last heard about them. The new laser prototype, in particular, is a beefed-up version of what we saw in 2013. It's capable of firing high-energy beams for $1 per shot, providing ships a low-cost alternative to weapons that require expensive ammunition. Within the past months, Navy engineers have consolidated the weapon's controls, so a single person can target, track and fire at threats like unmanned aircraft and attack boats using only a video game-like controller. The Navy wants to deploy this cost-effective death ray this summer aboard the same ship its predecessor occupied (the USS Ponce in the Gulf Sea), but it's still going through some final-stage adjustments.
