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
The B-52 Stratofortress is one of the oldest legacy aircraft in the Air Force. Since the 1950s, the B-52 has led the force in its dominance as the world’s best; however, just as humans begin to age, so do aircraft. Repeated loading and unloading, changes in air pressure, exposure to altitude and more, contribute to
NASA’s expertise in rocket engine improvement helps optimize plastic recycling process equipment. As good as it feels to throw plastic items into the recycling bin, the fact is most of that plastic goes unrecycled, according to Jim Garrett, a veteran of the oil and gas industry. “It’s a dirty little secret in America that 90
ALTUS AIR FORCE BASE, Okla. (AFNS) — A new training center for the KC-46 Pegasus was officially dedicated here Aug. 30, along with the activation of the 56th Air Refueling Squadron, which will be the formal training unit for the Air Force’s next-generation refueling aircraft. The integration of the KC-46 into the Air Force is
The Hall effect thruster (HET) was designed for long-duration operation with gaseous iodine as the propellant. Iodine is an alternative to the state-of-the-art propellant xenon. Compared to xenon, iodine stores as a solid at much higher density and at a much lower pressure. Because iodine is a halogen, it is reactive with some of the
The Marine Corps is modernizing one of its most reliable battle platforms: the M1A1 Abrams tank. A trio of upgrades to the tank commander’s weapon station will give tank commanders and gunners a “hunter-killer edge” over the enemy, according to an announcement from Marine Corps Systems Command. The improvements include better sights on the Abrams
There’s been a bit of a renaissance of sorts lately for pistol-caliber carbines, with a number of really interesting new options in 9mm on the market. We’ve reported on them in previous issues, and now we’re bringing you the latest just hitting stores as we speak. If you’re a luddite who doesn’t play video games
Although rechargeable batteries in smartphones, cars and tablets can be charged again and again, they don”t last forever. Old batteries often wind up in landfills or incinerators, potentially harming the environment. And valuable materials remain locked inside. Now, a team of researchers is turning to naturally occurring fungi to drive an environmentally friendly recycling process
The Indian Space Research Organisation (ISRO) is set to conduct air-breathing propulsion experiment using its RH-560 rocket fitted with a supersonic combustion ramjet (Scramjet) engine on August 28 from Sriharikota. According to ISRO Chairman A.S. Kiran Kumar, while the test would take place on August 28, the GSLV-F05 rocket with an indigenous cryogenic engine would
Raytheon is positioning itself to offer key missile defense assets that fill coverage gaps on the U.S. Navy’s littoral combat ships and new frigates, including upgraded surface-to-air missiles and new anti-ship and land attack missiles. The defense contractor is in talks with the service to field the sea version of their rolling airframe missile (SeaRAM)
