DAHLGREN, VA. — The Navy set a new world record for the most powerful electromagnetic railgun when it fired a test shot here Thursday morning.

The gun fired an aluminum projectile at 10.68 megajoules. A joule is the work needed to produce one watt of energy for one second. A megajoule is 1 million joules.

Guests including Chief of Naval Operations Adm. Gary Roughead and Rear Adm. William Landay, head of the Office of Naval Research, witnessed the shot via a live video feed at the Naval Surface Warfare Center in Dahlgren. The gun was launched from a control center after approximately four minutes of charging the electromagnetic rails. After the charge, the gun fired and witnesses saw a quick burst of flame as the projectile, traveling at 2,500 meters per second, or Mach 7, hit its target.

Contact Lenses With Circuits, Lights A Possible Platform For Superhuman Vision

Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes — visual aids to help vision-impaired people, holographic driving control panels and even as a way to surf the Web on the go.

The device to make this happen may be familiar. Engineers at the University of Washington have for the first time used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.

Redondo Beach, CA — Northrop Grumman Corporation has achieved two milestones that helped prepare the U.S. Missile Defense Agency’s (MDA) Airborne Laser (ABL) aircraft for integration of the Northrop Grumman-developed high-energy laser. Both accomplishments contributed to MDA’s success in meeting its fifth and final “Knowledge Point” or milestone for 2007 covering high-power systems integration readiness, continuing recent program progress.

Northrop Grumman’s Space Technology sector completed inspection and refurbishment of the components and parts that compose the Chemical Oxygen Iodine Laser (COIL), a megawatt-class laser the company designed and built for the ABL program. In conjunction with The Boeing Company (NYSE:BA), ABL’s prime contractor, Northrop Grumman also completed extensive engineering drawings for the installation of the laser. The drawings incorporate streamlined processes and other improvements learned during ground tests concluded in 2005.

“These achievements represent outstanding progress toward providing our nation with a mobile, speed-of-light capability to attack ballistic missiles during their boost phase,” said Alexis Livanos, corporate vice president and president of the company’s Space Technology sector.
