• New fog chamber offers testing options which could improve security cameras

    Fog can play a key role in cloaking military invasions and retreats and the actions of intruders. This is why physical security experts seek to overcome fog, but it is difficult to field test security cameras, sensors, or other equipment in fog that is often either too thick or too ephemeral. Until now, collecting field test data in foggy environments was time-consuming and costly. Sandia Lab researchers thought it would be more efficient to develop a controlled-fog environment for sensor testing – and they have developed a fog chamber — one of the world’s largest — that meets the needs of the military, other government agencies, and industry: The chamber is in a tunnel owned by the Air Force Research Laboratory.

  • Floods as tools of war: Many floods in the Netherlands in past 500 years were deliberately caused during wartime

    A new study shows that, from 1500 until 2000, about a third of floods in southwestern Netherlands were deliberately caused by humans during wartimes. Some of these inundations resulted in significant changes to the landscape, being as damaging as floods caused by heavy rainfall or storm surges. The study shows that floods in the Netherlands were used as a weapon as recently as the 1940s. “Strategic flooding during the Second World War undertaken by the Germans remained purely defensive, while the Allied flooding of the former island of Walcheren in the southwest of the country sped up the Allied offensive,” says the study’s author.

  • U.S. to increase annual military aid package to Israel from $3 billion to nearly $4 billion

    The U.S. defense aid to Israel will increase after 2017 from the current $3 billion a year to between $3.5 and $4 billion a year, according to both American and Israeli sources. The substantial increase in the military aid package to Israel is the direct result of the negotiations with Iran — and the fact that Sunni states in the region, such as Saudi Arabia and the Gulf States, will themselves see a major quantitative and qualitative increases in U.S. military aid to them, thus risking the erosion of the Israeli military’s “qualitative edge.” Only last year, the administration, in an effort to accommodate congressionally mandated cuts in the defense budget, informed Israel that the only changes to the package would be adjustment for inflation.

  • Israeli military technology sales to Africa increase by 40%

    Israeli weapons exports declined by nearly $1 billion in 214 compared to 2013, but export of Israel-made weapons to African countries increased by 40 percent in 2014 compared with 2013. Israeli armaments industries signed deals worth $318 million in Africa, compared with $223 million in 2013, which itself was an all-time record. Asian and Pacific countries were much larger customers of Israeli arms, though, buying $3 billion worth of Israeli military technology in 2014.

  • Researchers use seismic signals to track above-ground explosions

    Seismology has long been used to determine the source characteristics of underground explosions, such as yield and depth, and plays a prominent role in nuclear explosion monitoring. Now, however, some of the same techniques have been modified to determine the strength and source of near and above-ground blasts. Thus, researchers have determined that a tunnel bomb explosion by Syrian rebels was less than sixty tons as claimed by sources. Using seismic stations in Turkey, the researchers created a method to determine source characteristics of near-earth surface explosions. They found the above-ground tunnel bomb blast under the Wadi al-Deif Army Base near Aleppo last spring was likely not as large as originally estimated and was closer to forty tons.

  • U.S. security would be enhanced by minimizing role of nuclear weapons: Report

    Nuclear weapons remain the most potent destructive force known to humanity. Yet, U.S. nuclear policies and doctrines remain encumbered by cold war beliefs in the potential utility of nuclear weapons, even though the United States enjoys a dominant geopolitical position in the world, underpinned by a conventional military superiority greater than any ever known before. A news report argues that U.S. security interests would be better served if the role of nuclear weapons in U.S. strategy were minimized, and the United States, in its declaratory and weapon-development policies, would make it clear that U.S. nuclear weapons would serve only to deter other countries’ use of nuclear weapons against the United States and its allies.

  • Non-traditional roboticists to help bolster national security

    The past ten years have seen an explosion of robotics advances from small businesses and individuals, thanks in part to lower manufacturing costs and the global rise of community workshops such as makerspaces and hackerspaces, which serve as incubators for rapid, low-cost collaboration and innovation. Unfortunately, the small-scale robotics community has tended to fly under the radar of traditional federal agencies and commercial technology providers, which generally rely on multi-year, multi-million-dollar contracts for technology development. DARPA’s Robotics Fast Track foresees cost-effective development of new capabilities by engaging cutting-edge groups and individuals who traditionally have not worked with the federal government.

  • Obama halts transfers of military equipment to local police departments

    Since Congress launched the 1033 Program in 1997 to make military equipment that the Pentagon no longer wants available to state and local police. About $4.3 billion worth of equipment has been distributed. Between FY2009 and FY 2014, five federal agencies spent $18 billion on programs which provided funds and resources aiming to provide military equipment and tactical resources to state and local law enforcement agencies. The White House announced yesterday that it will ban federal transfers of armored vehicles, bayonets, grenade launchers, ammunition of .50-caliber or higher, and some types of camouflage uniforms to local police departments.

  • INL training military for response to radiological hazards

    Military branches from across the U.S. Department of Defense (DOD) sent candidates for an intensive Radiological Hazards and Operators Training and Field Exercise course (RHOT) conducted by the U.S. Army Medical Center and School. These students were brought to the Department of Energy’s Idaho National Laboratory (INL) site where they begin training to use radiological monitoring equipment, perform radiological calculations, and implement protective measures. Two weeks of intense training have transformed these responders into a cohesive unit able to work together to take decisive actions to secure and survey an area for radiological hazards.

  • Iran deal supporters: Comparisons with 1994 North Korea deal not applicable

    Critics of the nuclear agreement between Iran and the P5+1 powers charge that the negotiations, and the impending deal, repeat the mistakes the United States made in the nuclear deal it signed with North Korea in 1994. Supporters of the administration say there is no comparison between what happened twenty years ago and now. One example: the Agreed Framework between the United States and North Korea was a 4-page general document which did not include and reference to enforcement mechanisms should North Korea decide not to comply with the agreement. The emerging agreement with Iran, on the other hand, is a 150-page document dominated by intricate technical specifications and detailed procedures for inspection and verification, followed by specific benchmarks and definitions of violations and non-compliance and the resulting penalties which would be imposed on Iran should such violations occur.

  • Risks associated with nuclear modernization programs

    In the latest issue of the Bulletin of Atomic Scientists, experts from the United States, Russia, and China present global perspectives on ambitious nuclear modernization programs that the world’s nuclear-armed countries have begun.

  • Tests with Sandia’s Davis gun aid B61-12 life extension effort

    Three years of design, planning and preparation came down to a split second, a loud boom and an enormous splash in a successful impact test of hardware in the nose assembly of an unarmed, mock B61-12 nuclear bomb. The Sandia National Laboratories test also captured data that will allow analysts to validate computer models of the bomb, part of Sandia’s decade-long effort in the B61-12 Life Extension Program (LEP). An LEP is a way to extend the life of an aging weapon without adding new military capability. The B61-12 LEP is an $8.1 billion National Nuclear Security Administration (NNSA) program coordinated across the nation’s nuclear security enterprise.

  • U.S. Navy successfully demonstrates autonomous, swarming UAVs

    A new era in autonomy and unmanned systems for naval operations is on the horizon, as U.S. Navy officials last month announced recent technology demonstrations of swarming unmanned aerial vehicles (UAVs) — part of the Low-Cost UAV Swarming Technology (LOCUST) program. LOCUST can launch swarming UAVs to autonomously overwhelm an adversary.

  • Training the future canine force

    Canines have proven to be expert bomb detectors for U.S. troops in Iraq and Afghanistan. With combat operations winding down, however, the Office of Naval Research’s (ONR) Expeditionary Canine Sciences program says it is taking a fresh look at how dogs are trained to identify different explosive devices — and their roles in future conflicts. In addition to challenging dogs’ noses, ONR-sponsored research is studying their minds. Canines’ brains are evaluated using functional MRI machines (fMRIs) to determine how well they respond to various forms of motivation — snack treats, verbal praise, or physical affection such as petting.

  • Israel’s navy protects more than the country’s coast

    Cyber warriors working for Israel’s navy are constantly engaged in protecting against intense cyber intrusions which targets the country’s digital infrastructure, according to a senior navy source. “The navy understands that cyber conflicts are wars in their own right, beyond conventional conflicts that we have grown accustomed to. In cyber war, one can engage without firing a single bullet. Attacks can come before a conventional war. There are no official cease-fires. It goes on all of the time,” the source said.
