NRL Charters Navy’s Quantum Inertial Navigation Path to Reduce Drift

WASHINGTON – U.S. Naval Research Laboratory (NRL) researchers have developed a patent-pending continuous 3-D-cooled atom beam interferometer derived from a patented cold and continuous beam of atoms to explore atom-interferometry-based inertial measurement systems as a path to reduce drift in Naval navigation systems. Inertial navigation is a self-contained navigation technique in which measurements provided by…

Mark 21 Fuze

Major Milestone Reached for Key Weapons Component

ALBUQUERQUE, N.M. — Sandia National Laboratories and the Kansas City National Security Campus completed a crucial weapons component development milestone, prior to full rate production. The Mark 21 Replacement Fuze interfaces with the W87-0 warhead for deployment onto the Minuteman III and, eventually, the Sentinel Intercontinental Ballistic Missile. The first production unit of the replacement fuze…

RACER Speeds Into a Second Phase With Robotic Fleet Expansion and Another Experiment Success

DARPA’s Robotic Autonomy in Complex Environments with Resiliency (RACER) program successfully tested autonomous movement on a new, much larger fleet vehicle – a significant step in scaling up the adaptability and capability of the underlying RACER algorithms. The RACER Heavy Platform (RHP) vehicles are 12-ton, 20-foot-long, skid-steer tracked vehicles – similar in size to forthcoming…

Manta Ray UUV Prototype Completes In-Water Testing

The Manta Ray prototype uncrewed underwater vehicle (UUV) built by performer Northrop Grumman completed full-scale, in-water testing off the coast of Southern California in February and March 2024. Testing demonstrated at-sea hydrodynamic performance, including submerged operations using all the vehicle’s modes of propulsion and steering:  buoyancy, propellers, and control surfaces. “Our successful, full-scale Manta Ray…

Machine-Learning Algorithm Reveals Long-Theorized Glass Phase in Crystal

A dish made of crystal and a dish made of glass might look similar from the outside, but internally, their structures differ significantly. Crystals consist of perfectly ordered, repeating patterns of atoms, while glasses display a more disordered, fluid-like structure. For decades, scientists have been puzzled by glasses — how they form, what they are,…

AFRL Researchers Pave the Way to Lighter, Faster Additively Manufactured Rocket Engines

EDWARDS AIR FORCE BASE, Calif. (AFRL) – The U.S. Air Force Research Laboratory, or AFRL, Rocket Propulsion Division, recently designed, printed, built, and hot fired a first-ever, single-block rocket-engine thrust chamber additively manufactured using a process called laser powder directed energy deposition, or DED. “AFRL’s investments in early advanced manufacturing techniques enable us to exploit…

Rotating Detonation Engine Propulsion Integration Efforts at the U.S. Air Force Research Laboratory

Rotating detonation engines (RDEs) have garnered substantial attention as an emerging technology with applications to aerospace propulsion and energy generation due to their high-power density. Significant research and development have improved the operability and performance of RDEs, but relatively few studies have investigated the problems associated with integrating the combustor into an airframe. The U.S….
