The U.S. Army has taken delivery of equipment of the first increment of the Warfighter Information Network–Tactical (WIN-T). This phase of the program builds on the former Joint Network Node network and offers high-capacity secure communications when warfighters are not in transit. Devices include network hubs, management suites and nodes. The 5th Brigade, 2nd Infantry Division Stryker Brigade Combat Team is training with the equipment to prepare for operational tests and evaluations. The second increment of the program will include an initial on-the-move broadband networking capability using satellite and radio links. Fielding of phase-two equipment is scheduled to occur next year.

Members of the U.S. Coast Guard First District command center participated in an experiment simulating a scenario that examined decisions and actions to locate a vessel of interest and prevent a potential terrorist incursion. The Coast Guard worked with Raytheon Company on the experiment and used the company’s Mission Profiling process to study the potential for theoretical decision support tools and concepts of operations to improve a Coast Guard district command center’s maritime security mission. Several tools and concepts demonstrated potential for further investigation. The exercise was the first joint experiment under a Cooperative Research and Development Agreement signed by Raytheon and the Coast Guard Research and Development Center.

The U.S. Navy has commissioned the first littoral combat ship (LCS). The 378-foot USS Freedom features interchangeable mission packages so that it can be reconfigured for antisubmarine, mine and surface warfare on an as-needed basis. It is filled with advanced networking capabilities that enable it to share tactical information with other Navy aircraft, ships and submarines as well as with joint units. USS Freedom can operate in water that is less than 20 feet deep and can travel at speeds exceeding 40 knots. In addition to tactical and communications tasks, the new LCS will serve as the platform for launch and recovery of manned and unmanned vehicles.

The U.S. Navy and U.S. Air Force have signed a memorandum of agreement that will leverage development, production, sustainment and upgrade efforts for the RQ-4-based programs under each of the services. The agreement enables the services to continue to pursue common objectives across the RQ-4 enterprise while retaining each service’s specific mission and operational requirements. Military officials believe the agreement will promote cost savings and eliminate redundancies. The new memorandum will allow the Navy and Air Force to share data that will help ensure program effectiveness and help contractors increase quality and improve on-time delivery, they say.

The Malicious Code Research Center, Finjan Incorporated, has discovered examples of obfuscated code embedded not only in hypertext markup language Web pages on legitimate Web sites but also in rich-content files. According to a recently released Finjan report, popularity is increasing for online advertisements as well as user-generated content on Web 2.0 Web sites in directing users to malware-infected content files. Code obfuscation remains the preferred cybercriminal technique for their attacks, the report states.

The U.S. Army’s Future Combat Systems’ (FCS’s) Active Protection System (APS) has successfully passed stationary and moving target tests. The APS is designed to protect the FCS family of future manned vehicles from a variety of anti-tank and artillery projectiles. The APS is a vehicle-mounted system that defeats incoming threats such as rocket-propelled grenades and anti-tank guided missiles by physically destroying or deflecting them in flight. The APS launches vertically and then maneuvers to defeat single or multiple projectiles coming in from any direction.

The U.S. Army has begun its first large-scale deployment of a warfighter-wearable gunshot and sniper detection solution. The Army’s Rapid Equipping Force will begin distributingSoldier-Wearable Acoustic Targeting Systems (SWATS) to soldiers in Afghanistan and Iraq later this year; the distribution is expected to be complete by early next year. Part of the Ears Gunshot Localization System family of products, SWATS includes next-generation sensors and is ruggedized so that it can be used in current operations.

U.S. Army soldiers soon will be equipped with an enhanced night vision system that will increase their situational awareness in combat. Developed by BAE Systems through the Army’s Program Executive Office Soldier Enhanced Night Vision Goggle advanced technology development program, the digitally fused enhanced night vision goggle, ENVG (D), allows soldiers to view imagery that exploits features from visible, low-light and infrared sensors. The prototype system features a monocular eyepiece that provides several modes of fusion for varied mission needs, such as visible-only imagery, infrared-only images, monochrome fusion or colorized fusion with a user-selectable color palette.

Scientists at Argonne National Laboratory and Northwestern University have discovered a light-emitting compound that may assist optical communications as well as eventually help identify biological and chemical weapons at long distances. The compound structure almost went unnoticed because it grows lengthwise, creating long, thin crystals that are well suited for fiber optics but difficult for researchers to study. Scientists were able to determine the structure using the Chemistry and Materials beamline of the Center for Advanced Radiation Sources at the Advanced Photon Source.

The National Science Foundation is funding SRI International and the University of Michigan to use CubeSats in a program called CubeSat-based Ground-to-Space Bistatic Radar Experiment–Radio Aurora Explorer. CubeSats are small satellites, typically a 10-centimeter cube weighing one kilogram, used for science missions that are dedicated to space weather and atmospheric research. The program’s mission is to remotely explore small-scale ionization structures in the form of plasma turbulence that occurs in response to intense electrical currents in space. Those structures can have a negative impact on communications and navigation signals by perturbing the refractive index along signal propagation paths. The first launch is scheduled for December 2009.=
