Hydrazide Salts of Di‐Picric Acid as Dense and Insensitive Energetic Materials

Abstract. Energetic dipicrate hydrazide salts were synthesized by combining picric acid (PA) as anion and carbohydrazide and oxalyldihydrazide as cations in stoichiometric amounts (2 : 1 mol ratio). The structures of 2,2′‐carbonyldi(hydrazin‐1‐ium) bispicrate (1) and 2,2′‐(1,2‐dioxoethane‐1,2‐diyl)di(hydrazin‐1‐ium) bispicrate (2) were investigated by single‐crystal X‐ray diffraction analysis, illustrate that both crystals of 1 and 2 belong to the

Detecting Damage in Structural Components With New Infrared Technologies

Deterioration in bridges and other structures commonly manifests from subsurface damage that cannot be detected through visual inspections. Once the subsurface damage is observed through visual inspection, deterioration has advanced to a stage where significant repairs or even replacement may be required. Technologies that can detect the onset of deterioration in its earliest stages allow

US Navy Progresses HAAWC High-Altitude ASW Capability for Poseidon

The US Navy (USN) is pushing ahead with plans to field the High Altitude Anti-Submarine Warfare Weapon Capability (HAAWC) on the Boeing P-8A Poseidon maritime multimission aircraft (MMA), despite recent comments made to the contrary by some senior service officials. The aircraft original equipment manufacturer (OEM) is to be awarded a sole-source contract for full-rate

Ballistic Missile Defense Being Developed Against Decoys and Maneuvering Warheads

U.S. adversaries are developing sophisticated technologies to foil missile defense systems using innovative approaches like decoys to fool missile seekers, as well as maneuvering warheads able to dodge missile-defense systems. HUNTSVILLE, Ala. – Three U.S. prime defense contractors will share as much as $4.1 billion to help develop enabling technologies to enable U.S. ballistic missile

Israel Deploys Electronic Eye to Track Fire Kites and Balloons from Gaza

Sky Spotter can identify incoming airborne incendiaries, enabling drones to try intercept them, and giving firefighters advance warning; laser system also being developed. Facing a wave of airborne incendiary attacks from the Gaza Strip, Israel has deployed a system that can spot fire-starting balloons and kites in the sky, track their progress, and then direct

The Use of AI and Robotics in Weapon Systems

Many artificial intelligence (AI) and robotics technologies, including the cutting-edge ones, are dual use technologies. They have civilian and military applications. Besides defence contractors in the military industrial complex developing high tech robotic weapons, the same technology can be developed for civilian use, commercialized, and then exported to other countries. Even the humble robotic carpet

Army Moving Closer to Arming Systems With High-Energy Lasers

The U.S. Army is getting closer to mounting lasers on vehicles for protection against incoming enemy rocket, artillery and mortar fire. The Army awarded Raytheon Company a contract worth up to $10 million to develop a “100 [Kilowatt] class laser weapon system preliminary design for integration onboard the Family of Medium Tactical Vehicles,” or FMTV,

UK Centre of Excellence in Energetic Materials (CoEEM)

Centre of Excellence in Energetic Materials (CoEEM) is a UK Government-driven initiative to pull together and champion essential national capability in energetic materials. It aims to draw on UK-wide organizations, facilities, and academic centers to provide coordinated research, training, test & evaluation and knowledge exchange. Energetic materials, (explosives, propellants, pyrotechnics, gas generators) represent a vitally

DARPA Pursuing Global Positioning System Alternatives

The Defense Advanced Research Projects Agency is looking to develop alternative positioning, navigation and timing capabilities. Dave Tremper, a program manager at the agency’s strategic technology office, said relying solely on GPS provides users with a single point of failure. “GPS is so good that it’s kind of knocked all of the other players off

Advancing Squad-Level Mobility

U.S. Army Program Executive Office Combat Systems and Combat Service Support (PEO CS&CSS) is leveraging Other Transactional Authority (OTA), technical demonstrations, and Soldier feedback to speed acquisition of the Army’s new Squad Multipurpose Equipment Transport (SMET) robotic ‘mule.’ As power and equipment demands continue to increase Soldiers’ logistical burdens, the U.S. Army is working with

Russian Tank Doctrine Evolves to Combat Modern Threats

Russian tank forces have revealed details of new tank tactics during a battalion tactical exercise held in Voronezh, state news agency RIA Novosti reported on 4 July. The development indicates that tanks will continue to provide firepower in the future battlespace. Elements of the 20th Guards Army from the Western Military District demonstrated a series
