Directed-energy weapons systems could provide efficient, cost-effective countermeasures in an age of drones and other airborne threats. Recent scientific and engineering breakthroughs are bringing these systems closer to deployment. Long before George Lucas conceived of the Death Star with its super laser focused on Alderaan, even before H.G. Wells wrote War of the Worlds with
A newly discovered optical vortex forms a ring around many intense laser pulses but was never noticed before. In a typical optical vortex, light waves twist around a dark line, or hole, through the center of a light beam. Researchers have now uncovered an entirely different type of optical vortex that forms a ring, or
One of the efforts the Navy is undertaking under the guise of the third offset strategy — commonly described as undercutting adversarial advances through human-machine teaming — is a recently established initiative to examine interoperability between the service’s sensors, platforms and weapons. Task Force Netted Navy, which began in May 2016, is all about maximizing
Machine vibration often originates with rotating driveline components such as rotors, gears, bearings, and fans. Such vibration is the source of unwanted noise and can be destructive to the machine. The vibration ring is a mechanism that provides an indirect damping effect, and is rigid enough to be mounted within the driveline. The mechanical structure
Four-star Admiral Greenert, stating the Navy’s foremost priority before a distinguished audience of military, government, academia, and industry representatives in Washington, D.C. at the 2015 Naval Future Force Science and Technology Expo, repeated the enduring reality that, “Probably the biggest vulnerability of a ship is its magazine, because that’s where all the explosives are.” But
Researchers at the U.S. Naval Research Laboratory (NRL), Optical Sciences Division, in collaboration with the laboratory’s Material Science Division, for the first time have demonstrated successful detection of acoustic emission from cracks in riveted lap joints using a distributed feedback fiber laser-acoustic emission sensor. “An automated, in-situ structural health monitoring (SHM) system, capable of monitoring
The Navy”s new “first-of-its-kind” stealthy destroyer will soon go to San Diego, Calif., where it will go through what’s called “ship activation” – a process of integrating the major systems and technologies on the ship leading up to an eventual live-fire exercise of its guns and missiles. As part of this process, the Navy will
As the Air Force completed a month-long series of F-35 weapon tests, the Marine Corps is lobbying to add laser weapons to its version of the costly multi-role fighter. Lt. Gen. Robert Walsh, the Marine Corps” deputy commandant of combat development and integration, told reporters this week that directed energy weapons would lighten the fighter
Ongoing research on the Hoverbike, funded through the DSIAC contract, continues to demonstrate how new and disruptive technologies are being embraced by senior leadership within the US Army and DoD to change how we train and fight current and future battles. The following video shows the new U.S. Army Research, Development and Engineering Command (RDECOM)
In case you”ve forgotten the adage that “uncertainty is the only certainty,” Picatinny Arsenal”s Statistics Group is prepared to remind you. Its latest initiative known as “Uncertainty Quantification” focuses on studying engineering modeling and simulation uncertainty from a statistical standpoint and leveraging it as a more credible approach to weapon and munition product development. Uncertainty
WRIGHT-PATTERSON AIR FORCE BASE, Ohio — Creating, maintaining, protecting and expanding critical technology and technology resources is paramount to national security. A need to address increases in petroleum costs with an environmentally-friendly fuel source has led to a new way of looking at production—and the Defense Production Act Title III Program Office, part of the
The Army is developing a new 155 mm artillery round that will extend cannon range to more than 24 miles (40km), with the added benefits of greater safety for service members and the ability to deliver near-precision strike capability. The XM1113 Insensitive Munition High Explosive Rocket Assisted Projectile, or XM1113 RAP, will replace the aging
