National Defense Strategy

On October 27, 2022, the U.S. Department of Defense publicly released the unclassified National Defense Strategy (NDS), a Congressionally-mandated review. This strategy sets the strategic direction of the Department to support U.S. national security priorities and flows directly from President Biden’s National Security Strategy. The NDS includes the Nuclear Posture Review (NPR) and the Missile…

Notable Technical Inquiry

What over-the-horizon logistical resupply technologies are available for aerial and maritime unmanned aerial systems?

The Defense Systems Information Analysis Center (DSIAC) is seeking information on logistical resupply technologies for unmanned aerial and maritime vehicles with long range and low emission (heat, sound, and radar). The product should be TRL 7-9, US, NATO, FVEY, SWE, NOR, or JPN acceptable. Waterborne systems are of particular interest, but airborne systems would also be helpful. If you have expertise or points of contact related…

Models and Simulation Demonstrating Cavitation and Hydrodynamic Ram Effects Within Fuel Tanks

The Defense Systems Information Analysis Center (DSIAC) was asked to identify models, simulations, and tools used to model bubble growth, cavitation, and hydrodynamic ram (HRAM) effects within fuel tanks. When a high-velocity projectile penetrates or impacts a liquid-filled container such as a fuel tank, cavitation occurs. The cavity formed in the liquid results in extreme pressure, which may cause the liquid to bubble and eventually…

Hopping Gives This Tiny Robot a Leg Up

Insect-scale robots can squeeze into places their larger counterparts can’t, like deep into a collapsed building to search for survivors after an earthquake. However, as they move through the rubble, tiny crawling robots might encounter tall obstacles they can’t climb over or slanted surfaces they will slide down. While aerial robots could avoid these hazards, the amount of energy required for flight would severely limit…

Chainmail-Like Polymer Could Be the Future of Body Armor

Researchers supported by grants and instrumentation provided by the U.S. National Science Foundation have created the first 2D polymer material that mechanically interlocks, much like chainmail, and used an advanced imaging technique to show its microscopic details. The material combines exceptional strength and flexibility and could be developed into high-performance and lightweight body armor that moves fluidly with the body as it protects it. The…

U.S. Space Force Launches Six Experiments to International Space Station to Expand Scientific Knowledge in Support of Warfighters

KIRTLAND AIR FORCE BASE, N.M. – The U.S. Space Force (USSF) Space Systems Command (SSC), in partnership with the National Aeronautics and Space Administration (NASA), successfully launched the Space Test Program-Houston 10 (STP-H10) mission, which delivered five U.S. Department of Defense (DoD) and one NASA experimental science payloads, as a part of a resupply mission to the International Space Station (ISS). The DoD Space Experiments…

Aircrew Safety Improved With New Oxygen Purity Test at NAWCAD

NAVAL AIR WARFARE CENTER AIRCRAFT DIVISION, Patuxent River, Md. – For the first time, the Navy can precisely test how well modern oxygen systems remove impurities to ensure safe air for aircrew following a successful demonstration by teams at the Naval Air Warfare Center Aircraft Division (NAWCAD). There was previously no way to test whether oxygen systems meet the latest military standards that limit contaminants…
