U.S. Navy Selects Integrators to Evaluate Four Competitive Cyber-Warfare Concepts

Four system integrators were selected by the U.S. Navy Space and Naval Warfare Systems (SPAWAR) to develop cyberspace operations systems for the U.S. Navy, supporting the tactical, operational and strategic levels. The four include General Dynamics Advanced Information Systems, (GD-AIS) Science Applications International Corp. (SAIC), Northrop Grumman Systems Corp. and Booz Allen Hamilton, Inc. At its preliminary phase, the program addresses architecture assessment, examination, and demonstration, assessing operations requirements and analysis, concept formulation and development, feasibility demonstrations and operational support. Further phases include software design and implementation as well as systems integration, test and evaluation and demonstration. (Read More...)

irobotE-BCT Program Decisions Announced

The Department of the Army announced today that it decided to continue low-rate initial production of two elements of the Early-Infantry Brigade Combat Team (E-IBCT) program – the Small Unmanned Ground Vehicle and tactical network system. The E-IBCT investment of network technologies and software provide a foundation for growth of the Army’s tactical network. (Read More...)

Space Situational AwarenessU.S. Air Force Awards $214 Million to Improve Space Situational Awareness

Tens of thousands of small man-made objects known as ‘space junk’ are orbiting the earth, posing significant hazard to satellites, the International Space Station and other space hardware. Some objects are debris that separated from spacecraft in orbit while others are complete satellites that have ended their life and maintained in ‘parking’ orbit around earth. (Read More...)

Fuell cell generatorCompact JP-8 Diesel-Powered Fuel-Cell Demonstrates Long Operation Durability

The Department of Defense (DOD) has more than 100,000 electrical generator systems (“gensets”) deployed around the world. Supporting field installations with power for lighting, air conditioning, run computers, communications or medical equipment, these generators are major consumers of fuel. (Read More...)

New Guided Missiles, Programmable Munitions Enhancing The Infantry Precision Fire Effects

The 'Smart Weapon' approach is a more complex, expensive solution that could offer much higher precision – at the disadvantage of weight, complexity and cost. Lightweight weapons employ 'fire and forget' systems, enabling the missile to home-in on a designated target. Missiles are packing 'tandem' warheads for direct attack or Explosive Formed Projectile warheads for 'top attack', both capable of defeating even the world's heaviest, most protected tanks.
