Pathfinder Radar ISR and SAR Systems: Tactical Eyes for the Warfighter

Sandia National Laboratories’ (Albuquerque, NM) Radar Intelligence, Surveillance and Reconnaissance (ISR) systems enable a new product paradigm in radar capabilities and modalities. With the ability to shrink sensor size, increase resolution, raise image quality, and advance realtime onboard processing, Sandia has been producing next-generation systems for nearly three decades. Sandia specializes in the full system design of Synthetic Aperture Radar (SAR), Ground Moving Target Indicator (GMTI), target recognition, and other sensor systems for the Department of Defense, other government agencies, and industry partners.

Tiltrotor Aircraft

Bell Helicopter
Fort Worth, TX
817-280-2011
www.bellflight.com

During the thirty years since the V-22 Osprey first flew, the tiltrotor aircraft, built by Bell Helicopter, a Textron Inc. company, and Boeing, has fundamentally changed how the U.S. Marine Corps and Air Force operate in combat and support humanitarian operations. So far, more than 375 V-22 aircraft have accumulated more than 450,000 flight hours across a spectrum of missions. The aircraft has proven to be so versatile that the U.S. Navy now has plans to begin leveraging the Osprey’s unique capabilities by using a new V-22 variant to deliver personnel and cargo to its aircraft carriers.

Mine Roller

Rostec State Corporation
Moscow, Russia
+7 (495) 287-25-25
https://rostec.ru/en/

Chelyabinsk Tractor Plant, part of UralVagonZavod Group belonging to Rostec State Corporation, has developed a mine roller to be installed on "ironclads” — models B10M2S and B12S armored tractors. The B10M2S is an armored bulldozer designed and built by Company Uralvagonzavod (UVZ), a subsidiary of Rostec State Corporation. The bulldozer, which has a maximum weight of 22,800 kg (50,265 lbs), is powered by a 190 hp YaMZ-236 diesel engine, giving it a top speed of 11 km/h (6.8 mph). Tractors with a mine roller are more maneuverable than mine-clearing tanks and have a longer service life, which makes them optimal for humanitarian demining. Production of a prototype mine-clearing tank was scheduled to begin in the first quarter of 2019.

In early 2019, the DGA (French Procurement Agency) and the French Army (STAT) organized a campaign to test the MMP land combat missile in extreme cold conditions. Performed on the Swedish state firing range at Vidsel, located near the Arctic Circle with temperatures between -15°C and -30°C, the cold weather campaign of the MMP was determined to be a complete success.

Feasibility Study of Portable Water Desalination Systems for Water Contingencies at Remote Navy Installations

The Department of the Navy (DON) has major installations located around the world. Twenty-two main installations operate outside the continental United States (OCONUS) and rely on on-base water processing facilities. These facilities serve a total population of 71,000 military and civilian personnel, and the water plants have a total production capacity of 15.7 million gallons per day.

Nominal High-Altitude Electromagnetic Pulse (HEMP) Waveforms

Even before the Trinity nuclear test in July of 1945, physicists predicted a transient electromagnetic signal would be caused by high-energy photons released from the detonation interacting with the air around the detonation. Predictions of these signals were difficult to make due to the complexity of the physics unleashed by the detonation.

Hands-on Cybersecurity Studies: Multi-Perspective Analysis of the WannaCry Ransomware

Ransomware is malware that obstructs a user from accessing digital assets through various mechanisms. These assets are held hostage and inaccessible until the user pays a ransom. In most cases, this is accomplished using encryption where, once the malicious program executes, it will target and encrypt certain files and will release the decryption key at the time of payment. Some ransomware instances target only certain common user-generated files such as media and documents. In this case, system files and others required for the operating system to function correctly (user authentication, process execution, etc.) are unaffected. Others encrypt much more and seek to lock out entire systems.
