The US Navy's Electromagnetic Rail Gun that is under development at NSWC Dahlgren in Virginia. This is a prototype to demonstrate the technology of the rail gun for use on the future DDG-1000 class of Navy ships. This clip is from the show FutureWeapons on the Discovery Channel. It aired in April 2007. The show occasionally repeats on the Military Channel (part of the Discovery Channel family). (NOTE - This has nothing to do with the movie Transformers 2.)
