The Navy Is Teaching Celestial Navigation Again as a Backup Plan Against Hackers 

The Naval Academy hasn’t taught midshipmen how to navigate by the stars in nearly 20 years, but it’s reintroducing the old-school approach to maritime travel. Why use a sextant instead of computers and GPS? Worries about ships stranded by cyber-attacks, which have the Navy re-thinking its reliance on tech. »10/13/15 4:30pm10/13/15 4:30pm

These Underwater Mountains Are More Dangerous Than They Look

The ocean can look enormously peaceful, like a postcard sent from heaven by someone on Xanax. Under the surface, things aren't nearly so calm and picturesque.

The Trillion Dollar F-35 Won't Even Be Able to Shoot Its Gun Until 2019

At this point, it's not even funny how much the Pentagon has screwed up the development of its new stealth fighter jet, the F-35. But the latest report that the jet's 25mm cannon won't be operational until 2019 at the earliest is just laughable. Even more laughable is that it probably doesn't even need the gun to… »12/31/14 2:48pm12/31/14 2:48pm

The Navy once tried using nuclear-powered wetsuits to keep divers warm

The ocean is an inhospitable place for soft, land-based human bodies. It's dark, oxygenless, and, perhaps most intractable of all, really cold. At the pressure of certain depths, neoprene suits will compress and lose their insulating power. The air in tanks also gets cold, so divers become chillier with each breath.… »12/02/14 1:25pm12/02/14 1:25pm
