The US Navy has a reputation for being much like its main form of transportation — a big ship that’s slow to change course. After decades of relying on large-scale warships like the aircraft carrier, the Navy has been working toward a smaller, more flexible fighting force. With the impending launch of the USS Zumwalt, the Navy will be moving well into a high-tech, Linux-powered future.

The USS Zumwalt is to be the first ship in the Zumwalt class of guided missile destroyers. However, it’s going to be a first in more ways than that. This ship has been built around stealth and firepower, with a heart of easy-to-maintain enterprise-grade electronics. The servers running the Zumwalt are IBM blades with Red Hat Linux and are housed in hardened enclosures deep within the ship. Each of the massive Electronic Modular Enclosures (EME) is resistant to shock, vibration, electromagnetic pulse, and has a built-in water cooling system. This makes the USS Zumwalt probably the most secure and heavily armed data center on the planet.

The Zumwalt’s Common Display System, or CDS is a cluster of 3-screen server workstations running Intel Xeon processors and multiple LynxOS-based Linux virtual machines. This approach allows multiple networks to be running simultaneously within the CDS with different levels of system access. In the CDS, the crew will be able to manage any function of the ship without moving to a different station. The 600 ft craft will, of course, be packing serious firepower, as any self-respecting warship should. The USS Zumwalt will carry a massive 155mm rocket-powered projectile dubbed the Advanced Gun System, making it more powerful than ships twice its size. Each Zumwalt-class destroyer will cost the Navy $3.45 billion, so at least they’re saving money using Linux.
