Defense & Military

Current weapons generally fly a pre-designated mission. If the enemy does something unexpected, preprogrammed weapons are ineffective, and additional weapons may be required to complete the mission. Autonomous, Networked, and  collaborative weapons are advantageous since they observe and react to the enemy in real time, helping weapons overcome adversary defenses …

Chinese military has been engaged in comprehensive modernization of  its air, naval, and ground forces, while incorporating a variety of anti-access/area denial (A2/AD) systems and capabilities.  “To operate against adversaries with “anti-access / area denial” capabilities the U.S. needs to disperse its forces, disaggregate its capabilities, confuse enemy sensors through …

According to the University of Maryland’s Global Terrorism Database, there were a total of 143 attacks – 35 biological, 95 chemical, and 13 radiological – using CBRN weapons across the world from 1970 to 2014. The relative ease with which malicious actors could obtain many of the materials and know-how …

Underwater communication is vital for undersea exploitation and modern communication. Conventional ways which employ acoustical technique for underwater communication have their drawbacks  including high path loss, narrow bandwidth, high bit error rate, among which unconditional security is more demanding due to commercial and secure interest.   Submarine communications have always been a challenge …

Alexander Graham Bell discovered photoacoustics by accident when he was working on the development of the photophone, a followup to his recently developed telephone that operated via modulated sunlight instead of electricity. You would operate a photophone by speaking into its transmitter toward a mirror placed inside of it. The vibrations …

As the space domain has become more congested, the potential for intentional and unintentional threats to space system assets has increased. Space is also becoming another domain of conflict due to enhanced militarization and weaponization of space. There has been enhanced testing of Anti-satellite weapons (ASAT) and space weapons designed …

The world, say many experts, is on the verge of a second quantum revolution. Energy quantization gave us modern electronics via the transistor and the laser, but humans’ burgeoning ability to manipulate individual atoms and electrons could potentially transform industries ranging from communications and energy to medicine and defense. The most …

Traditional missiles powered by rocket motors typically carry both fuel and oxidizer. An air-breathing ramjet missile can dispense with the separate oxidizer payload, reducing the size of a propulsion package.  Thanks to ramjets, smaller missiles use that space for other things, like a bigger warhead or more fuel. Ramjets, according to …
