Our coverage of Lockheed Martin here on Engadget normally focus on things like laser weapons or futuristic airships, but it looks like the mega-defense company is now trying its hand as something a little closer to home for us: an ultra-secure USB flash drive. As you can see above, that's done with a little help from the folks at IronKey, but Lockheed Martin does seem to have made its new IronClad its own, and included some custom software that promises to let you carry your entire computer with you and securely use it on any public computer. Of course, exact details are a bit hard to come by, but the drive is available with "at least" 8GB of storage, and includes 256-bit encryption, built-in virus protection, and a variety of networking features that will let organizations keep watch on individual drives and control what can or cannot be installed on them. No word on pricing, but Lockheed Martin is apparently ready to talk with any companies that are interested in using the drives.
