Pandemics  may threaten both internal and external national security – the physical threat to U.S. citizens in terms of morbidity and mortality, and the decreased effectiveness of U.S. armed forces in protecting those citizens from external threats.  The economic, political or social turmoil in adversary country is also potential threat. …

Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. Repair of certain materials during their lifecycle (especially those with structural functions such as concrete) can be very expensive and labour intensive.  Therefore Scientists began developing self-healing materials ,  those artificial (synthetic) substances that …

LIDARs are rapidly gaining maturity as very capable sensors for a number of applications such as imaging through clouds, vegetation and camouflage, 3D mapping and terrain visualization, meteorology, navigation, and obstacle avoidance for robotics as well as weapon guidance. LIDAR data is both high-resolution and high-accuracy, enabling improved battlefield visualization, …

Intelligence, in military science, information concerning an enemy or an area. The term is also used for an agency that gathers such information. Military intelligence is as old as warfare itself. Even in biblical times, Moses sent spies to live with the Canaanites in order to learn about their ways and …

The electromagnetic pulse commonly abbreviated as EMP, is a high-intensity burst of electromagnetic energy caused by the rapid acceleration of charged particles, can be produced by intense solar storms or by a nuclear weapon detonated high in the atmosphere. For example, solar geomagnetic storms (geomagnetic disturbances or GMD) create immediate …

A Sensor is an electronic device that is used to measure some sort of physical parameters (e.g. temperature, pressure, light intensity, etc). The output of an electronic sensor is an electrical signal that is either analog or digital. Processing the sensor’s output can be done in hardware (using discrete electronic …

Air medical services is a comprehensive term covering the use of air transportation, aeroplane or helicopter, to move patients to and from healthcare facilities and accident scenes. An air ambulance is often required to provide urgent evacuation from a remote or medically under-served area to a more suitable, higher-level medical …

Underwater warfare is one of the three operational areas of naval warfare, the others being surface warfare and aerial warfare. It refers to combat conducted underwater such as: Actions by submarines actions, and anti-submarine warfare, i.e. warfare between submarines, other submarines and surface ships; combat airplanes and helicopters may also …

Fly-by-wire (FBW) systems are semi-automatic, computer-regulated aircraft flight control systems that replace mechanical flight controls with an electronic interface. When the pilot moves flight controls, those movements are converted into electronic signals, which are then interpreted by the aircraft’s flight control computers (FCC) to adjust actuators that move flight control …
