  • Testing Cutting-Edge Counter-Drone Technology

    Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.

  • China Shows How Western Governments Should Stockpile Minerals

    The US, Australia and partner countries should take a page from China’s stockpiling playbook. They should build up stockpiles of critical minerals, managing inventories to optimize prices for domestic mineral producers and consumers and to guard against decreased supply and increased demand in wartime.

  • High-Energy Laser Weapons: How They Work and What They Are Used For

  • Low-Level Blasts from Heavy Weapons Can Cause Traumatic Brain Injury − Two Engineers Explain the Physics of Invisible Cell Death

    When the force of a blast shoots a round out of a large-caliber rifle, howitzer or M1 Abrams tank gun, the teams of people operating these weapons are exposed to low-level blasts that can cause traumatic brain injuries. Low-level blasts do not cause visible trauma, yet, these blasts can cause physical changes in the brain that lead to a host of neuropsychiatric symptoms.

  • Charting the Future of Maritime Security

  • Cult of the Drone: At the 2-Year Mark, UAVs Have Changed the Face of War in Ukraine – but Not Outcomes

    Unmanned aerial vehicles, or drones, have been central to the war in Ukraine.

  • Are Drones Revolutionizing Warfare? They Do Not, Skeptics Argue

    Drones have been employed by both sides to the Russia-Ukraine war on unprecedented scale. The prevalence of drones in Ukraine and other recent conflicts has led some observers to conclude that drones are revolutionizing warfare, while other analysts argue that drones are incremental improvements to existing technologies. These drone-skeptics contend that drones are not fundamentally shifting the character of war.

  • Trump-Biden Spat on NATO Highlights Divide on America’s Role in the World

    Former President Donald Trump doubled down on his threat that, if elected, he would not defend NATO members who don’t meet defense spending targets.
