For the Marines, a New Commandant Sees a New Corps, in a New Era of Warfare
The Marine Corps’ new commandant, Gen. David Berger, is breaking china, figuratively, to enable the Marines to break China, literally, should a conflict erupt in East Asia. As the only service whose forces are mandated by law — three divisions and three air wings — the Marines have relied on their traditional hold over Congress
U.S. Army Research Uncovers Pattern in Progression of Weapons Technologies
Anticipating the technology and weapon systems of our future Army might not be entirely daunting, new Army research finds. Trends in the progression of weapon systems from the early crossbowman to a musket to a military tank might help predict our future systems, according to a new study to be published in the Journal of
SPECIAL REPORT: ARL Director Focused on Top 10 R&D Priorities
This is part 1 of a 2-part special report on Army R&D. The U.S. Army Research Laboratory (ARL) is zeroed in on key initiatives aimed at giving soldiers an edge on future battlefields against advanced adversaries. There are only 10 efforts that have been deemed essential research programs, ARL Director Philip Perconti noted in an
3-D Printing for Ecological Sustainability in Marine Applications
In the recently published “Recycled Sustainable 3D Printing Materials for Marine Environments,” the authors—involved in the Bio-Shelters Project—venture into the realm of sustainability and recycling in 3-D printing, but they also heavily explore the ever-growing science of materials during a three-phase project made up of not only designers and architects but also experts in materials
NASA Engineer Proposes “Helical Engine” for Interstellar Travel With No Propellant
An engineer who works for NASA has put forward a proposal for a new way to travel through interstellar space—a “helical engine” that could, potentially, push a spacecraft forward without the need for any propellant at all. David Burns, from NASA”s Marshall Space Flight Center, presented his idea on the space agency”s Technical Reports Server,
DARPA’s Mosaic Warfare — Multi Domain Ops, But Faster
WASHINGTON: Just when you thought you understood Multi-Domain Operations (MDO), along comes the Defense Advanced Research Projects Agency’s “Mosaic Warfare.” It’s sort of MDO on steroids: an all-encompassing “force design” — that includes everything from military organization to operational concepts to weapon systems to tactics — to underpin a new U.S. way of war targeted
U.S. to Spend Hundreds of Millions to Replace a $5 Part in Revamped Nuclear Weapons
Concerns about the reliability of commercial-off-the-shelf capacitors, each of which cost just $5, and that the Department of Energy had been planning to use in two future nuclear warhead designs will delay both programs by at least a year and a half and could result in up to a whopping $850 million in additional costs.
