The AN/AAR-57 Common Missile Warning System (CMWS) helps protect Army aircraft from attack by shoulder-launched missiles and other threats. To keep this defensive system operating at maximum effectiveness, the Army periodically updates the software on the more than 1,000 AN/AAR-57 units in use around the world.
An interdisciplinary development team that includes Lockheed Martin, the Air Force Research Laboratory and the Univ. of Notre Dame has demonstrated the airworthiness of a new beam control turret being developed for DARPA to give 360-degree coverage for high-energy laser weapons operating on military aircraft. An aircraft equipped with the laser has already conducted eight test flights in Michigan.
New technology under development at the Univ. of California, Berkeley could soon give bomb-sniffing dogs some serious competition. A team of researchers has found a way to dramatically increase the sensitivity of a light-based plasmon sensor to detect incredibly minute concentrations of explosives.
The possibility that the civilian jetliner downed over war-torn eastern Ukraine with nearly 300 people onboard was hit by a missile could have profound consequences for the world's airlines. Airlines might have to be more vigilant about avoiding trouble spots, making flights longer and causing them to burn more costly fuel. They may even be forced to reconsider many international routes.
Japan has approved the export of a locally-made component for a missile defense system to the U.S. and is launching joint research with Britain on air-to-air missile technology for fighter jets. The approval late Thursday marks the first defense technology transfer since Japan eased military export rules in April.
In early March, a mysterious ship the size of a large passenger ferry left Romania and plotted a course toward Scandinavia. About a month later, at the fenced-in headquarters of Norway's military intelligence service, the country's spychief disclosed its identity. It was a $250 million spy ship, tentatively named Marjata, that will be equipped with sensors and other technology to snoop on Russia's activities in the Arctic beginning in 2016.
The U.S. Army’s Edgewood Chemical Biological Center now completing a multi-year effort to refine several new smoke screen compositions that will allow troops to mask themselves from enemy fire. Intended to at last replace the World War II-era hexachloroethane smoke grenades that produce a toxic, irritant containing zinc chloride, the new formulations range from “black smoke” to lithium combustion technology.
The Navy plans to deploy its first laser on a ship later this year, and it intends to test an electromagnetic rail gun prototype aboard a vessel within two years. For the Navy, it's not so much about the whiz-bang technology as it is about the economics of such armaments. Both costs pennies on the dollar compared with missiles and smart bombs, and the weapons can be fired continuously, unlike missiles and bombs, which eventually run out.
Military brass shopping at Asia's biggest defense expo this week have drones high on their to-buy list. But for U.S. manufacturers including General Atomics, which makes the Predator hunter-killer, there's one problem: they can only sell to a few countries because of tight export restrictions.
A ground-penetrating bomb, minus its nuclear components, rammed through a target at the remote Coyote Canyon test range last month in Sandia National Laboratories’ first such rocket-driven impact test in seven years. Engineers said the Sandia components on the weapon performed as expected.
The number of countries possessing the makings of a nuclear bomb has dropped by almost one-quarter over the past two years, but there remain "dangerous weak links" in nuclear materials security that could be exploited by terrorist groups with potentially catastrophic results, according to a U.S. study released Wednesday.
R&D among aerospace, defense and security firms is primarily driven by two sectors: the U.S. Department of Defense (DOD) and the global airline industry. The major aerospace and defense contractors plan R&D in close coordination with DOD to meet the needs of national defense and global security, while capacity, economics and efficiency are drivers for civil aviation requirements.
The Office of Naval Research is demonstrating the Fleet Integrated Synthetic Training/Testing Facility (FIST2FAC) in Florida this week, showing how gaming technology is helping naval forces develop operations strategies in a hassle-free way.
The U.S. Naval Research Laboratory (NRL)'s Acoustics Div., with Bluefin Robotics, executed a record setting 507 km (315 mile), long-endurance autonomy research mission using its heavyweight-class mine countermeasures autonomous underwater vehicle (AUV), Reliant. NRL's Reliant AUV, when equipped with a low-frequency broadband sonar system, is perhaps best known as the prototype for the new U.S. Navy Knifefish mine-hunter.
For the threat of meteor strikes large or small, early detection is key, and evacuation may be the only defense needed within the next 1,000 years, according to an asteroid impact expert. The best investment in asteroid defense is not in weapons to deflect them, but in telescopes and surveys to find them.
United Technologies Corp. canceled a planned furlough of 2,000 workers after the U.S. Dept. of Defense recalled most of its civilian employees. The Hartford, Conn.-based defense contractor planned to furlough 2,000 workers starting Monday. Its Sikorsky division makes Black Hawk helicopters for the military and relies on government inspectors, who were furloughed.
At the U.S. Army Edgewood Chemical Biological Center, experts have been conducting research of “organs” on microchips. Unlike the few other laboratories conducting these types of studies, the Army is specifically looking at potential scenarios that will affect warfighters, especially chemical agent exposure.
Sandia National Laboratories scientists are thinking small, building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans. Their potential seems unlimited. The military needs to find low concentrations of chemicals, such as those used in roadside bombs or chemical warfare agents, before they hurt anyone.
Researchers at Georgia Tech are helping the U.S. military make key changes in how aircraft electronic systems, called avionics, are produced. The effort focuses on modifying the design of avionics software, especially the ways in which it interfaces with an aircraft's hardware and other software. The work is part of the U.S. Navy's Future Airborne Capability Environment (FACE) project.
In complex crisis situations teams of experts must often make difficult decisions within a narrow time frame. However, voluminous amounts of information and the complexity of distributed cognition can hamper the quality and timeliness of decision-making by human teams and lead to catastrophic consequences. A Penn State Univ. team has devised a system that merges human and computer intelligence to support decision-making.
When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals: a technique known as electronic attack (EA) or jamming. Conversely, electronic protection technology prevents hostile forces from using EA methods to disable U.S. radar equipment assets. A research team is now developing a new generation of advanced radio frequency jammer technology.
Purdue Univ. researchers are peering into the future to help the U.S. foil enemy missile attacks. Working with the U.S. Missile Defense Agency, the research team is creating software that makes it possible to pose various "what-if" questions; scenarios that explore plausible future missile advances in adversarial nations and the defensive capability of the U.S.
France has become the first country to receive an A400M military transport plane from Airbus, bringing to fruition a long-troubled program. The delivery Thursday culminates "a long, complex and thorough process" between Airbus Military and the seven European nations behind the program, France's DGA military procurement agency said in a statement.
Fluxes and turbulence caused by the interaction between the air and sea can significantly alter the path of electromagnetic waves in radar and communications systems. In effort to boost the U.S. navy’s communications performance at sea, researchers deployed Office of Naval Research unmanned aerial vehicles (UAVs) in an effort to determine the ocean and atmospheric weather variations that can change the angle that radar and radio waves bend.
American information is so valuable, experts say, that no amount of global outrage over secret U.S. surveillance powers would cause Britain, Canada, Australia and New Zealand to ditch their collaborative spying arrangement: the Five Eyes. Revelations from NSA leaker Edward Snowden, they say, are unlikely to stop or even slow the global growth of secret-hunting—an increasingly critical factor in the security and prosperity of nations.
