Xbox 360 controllers have long since been replaced by Microsoft, but an unlikely source is getting a second lifespan out of them: the U.S. Navy. The Navy is starting to use repurposed Xbox 360 controllers to control the periscopes on some of its submarines, according to The Virginian-Pilot. In the past, many Virginia-class submarines used mast-mounted cameras to see above the water and they required helicopter-like joysticks that required extensive training and were costly to use. According to Lockheed Martin, a standard control panel would usually be $38,000 per unit. For the Navy and partner Lockheed Martin, a major reason behind the change was familiarity.
