Lockheed Martin IronClad is PC-on-a-stick for real road warriors

A US defence company better known for building the F-35 Joint Strike Fighter and NASA's next manned spaceship, the Orion, has just announced the death

A US defence company better known for building the F-35 Joint Strike Fighter and NASA's next manned spaceship, the Orion, has just announced the death of laptops - or at the very least, the end of spies and politicians leaving sensitive data on them in trains and cabs.

The IronClad USB drive contains everything you need to shrink your computer to a three-inch ultra-secure chunk of solid metal. The Ironclad contains operating system, applications and data in its 8GB (minimum) innards, letting you plug in to almost any PC, bypassing its hard drive completely and leaving 'no trace' you were ever there.

Lockheed Martin calls the Ironclad 'totally secure', using 256-bit military grade encryption to protect your data together with built-in secure software applications to bust malware and viruses. Remote management lets you turn lost Ironclads into 'bricks', embedded security systems limit new software installations and the Ironclad itself is waterproof and tough enough to withstand significant shocks, heat and cold.

There's no price details on the IronClad yet but this kind of military kit never comes cheap.
