Electronic oscillators lie at the heart of virtually all microelectronic systems, generating the clock signals used in digital electronics and the precise frequencies that enable radio frequency (RF) sensors and communications. While an ideal oscillator provides a perfect signal at a single frequency, imperfections degrade the spectral purity of real-world components.

Such impairments, broadly quantified as phase noise, ultimately limit the performance of many military radars and commercial 5G systems. The issue is becoming increasingly burdensome as the airways become more congested and defense needs evolve.

Based on the recommendations of weather forecasters, Operation Overlord’s June 5 D-Day was postponed due to a weather front. However, the operation was launched one day later when analysis projected a short period of acceptable weather. Germany’s forecasters missed this break, and the results were cataclysmic for German forces.

The Korean and Vietnam conflicts highlighted a growing need for “weather superiority” as enemy forces learned to take advantage of periods of bad weather that limited the effectiveness of U.S. air forces. Even in Desert Storm, the first item in planning the daily air operations began with a weather forecast.

Today, superior knowledge of environmental conditions is a force multiplier for all the services in an era where concepts like Joint All-Domain Command and Control are accelerating the speed and precision at which war is conducted. The outcome of future conflict will depend on rapid, accurate and more fully informed decisions. If a commander lacks an assured source of high-fidelity intelligence about the environment, then tools, tactics and timing cannot be aligned to achieve desired outcomes.

NGAD is the Navy’s effort to replace the Super Hornet. Note: It’s a completely separate program from the Air Force’s own NGAD—which recently designed, tested, and flew a secret new fighter jet—and will produce a completely separate plane. The two aircraft will almost certainly be quite different, with the Air Force’s jet more optimized for air superiority. It’s likely the two fighters, developed roughly within the same time period, will share much of the same technology.


The U.S. Navy elaborated on its plans to replace the F/A-18E/F Super Hornet, saying the service’s next strike fighter will “most likely be manned.” The jet will probably fly alongside robotic allies, and remotely crewed aircraft could eventually account for six out of 10 planes on a carrier flight deck.

“As we look at it right now, the Next-Gen Air Dominance [NGAD] is a family of systems, which has as its centerpiece the F/A-XX—which may or may not be manned—platform. It’s the fixed-wing portion of the Next-Gen Air Dominance family of systems,” said Rear Adm. Gregory Harris, the head of the Chief of Naval Operations’ air warfare directorate, during a Navy League event.

The F/A-18E/F Super Hornet dominates Navy’s strike fighter fleet, made up of fighters that can execute both fighter and attack missions. Although the Navy is buying the F-35C Joint Strike Fighter, it’s only purchasing enough of the planes to replace one or two of the four strike fighter squadrons per deployed aircraft carrier. The Navy believes it needs to replace the Super Hornet and its electronic warfare variant, the EA-18G Growler, in the 2030s.

Russia is amassing unprecedented military might in the Arctic and testing its newest weapons in a region freshly ice-free due to the climate emergency, in a bid to secure its northern coast and open up a key shipping route from Asia to Europe.

Weapons experts and Western officials have expressed particular concern about one Russian ‘super-weapon,’ the Poseidon 2M39 torpedo. Development of the torpedo is moving fast with Russian President Vladimir Putin requesting an update on a “key stage” of the tests in February from his defence minister Sergei Shoigu, with further tests planned this year, according to multiple reports in state media.

This unmanned stealth torpedo is powered by a nuclear reactor and intended by Russian designers to sneak past coastal defences — like those of the US — on the sea floor.

An Iranian military ship linked to alleged spying activities was attacked Tuesday by Israeli forces as it was stationed in the Red Sea, according to U.S. and Iranian officials.

Pentagon spokesperson Commander Jessica L. McNulty said in a statement to The Hill that the U.S. was “aware of media reporting of an incident involving the Saviz in the Red Sea.”

“We can confirm that no U.S. forces were involved in the incident,” McNulty continued, adding, “We have no additional information to provide.”

Exosonic isn’t the only aviation trailblazer to receive investment from the US Air Force.

Atlanta-based Hermeus Corporation is working on a hypersonic 20-seater that promises to deliver passengers from New York to London in 90 minutes.


California start-up Exosonic is developing a supersonic jet designed to one day carry the leaders of the US Executive Branch and their guests. CNN Travel got a sneak peek inside the plane.

Researchers at Tel Aviv University were able to reconstruct the nutrition of stone age humans.

In a paper published in the Yearbook of the American Physical Anthropology Association, Dr. Miki Ben-Dor and Prof. Ran Barkai of the Jacob M. Alkov Department of Archaeology at Tel Aviv University, together with Raphael Sirtoli of Portugal, show that humans were an apex predator for about two million years. Only the extinction of larger animals (megafauna) in various parts of the world, and the decline of animal food sources toward the end of the stone age, led humans to gradually increase the vegetable element in their nutrition, until finally they had no choice but to domesticate both plants and animals — and became farmers.

“So far, attempts to reconstruct the diet of stone-age humans were mostly based on comparisons to 20th century hunter-gatherer societies,” explains Dr. Ben-Dor. “This comparison is futile, however, because two million years ago hunter-gatherer societies could hunt and consume elephants and other large animals — while today’s hunter gatherers do not have access to such bounty. The entire ecosystem has changed, and conditions cannot be compared. We decided to use other methods to reconstruct the diet of stone-age humans: to examine the memory preserved in our own bodies, our metabolism, genetics, and physical build. Human behavior changes rapidly, but evolution is slow. The body remembers.”

For 50 years, AeroVironment has advanced UAV development. Today, the company is a Technology Solutions Provider at the intersection of four future-defining technologies: robotics, sensors, analytics and connectivity. Its culture of experimentation and R&D dates back to its founder, Dr. Paul MacCready Jr., whose achievements earned him the nickname “the father of human-powered flight”. From deploying the world’s most popular sUAS to designing the helicopter that’s en route to fly in Mars’ thin atmosphere, AeroVironment’s collective accomplishments provide a case study of imagination, innovation and collaboration — one that has and will bring effective solutions to frontlines, farms and frontiers, yesterday, today and tomorrow.

Leading the Way: UAS Capabilities – Onward and Upward

From solar-powered aircraft to the first hand-launched small UAS (sUAS) for military reconnaissance, AeroVironment literally launched the era of small aerial vehicles for environmental, commercial and defense purposes. For 35 years, the company has made its UAVs smaller and simpler, yet with multiple and ever-more-innovative functionality.

Colonel Mark M. Zais, chief data scientist at United States Special Operations Command (USSOCOM) stresses the importance of AI-related education in the DOD. In his 2020 CJCS Strategic Essay Competition first place Strategy Article, he says, “Without that education, we face a world where senior leaders use AI-enabled technologies to make decisions related to national security without a full grasp of the tools that they—and our adversaries—possess.”


With the release of its first artificial intelligence (AI) strategy in 2019, the Department of Defense (DOD) formalized the increased use of AI technology throughout the military, challenging senior leaders to create “organizational AI strategies” and “make related resource allocation decisions.”1 Unfortunately, most senior leaders currently have limited familiarity with AI, having developed their skills in tactical counterinsurgency environments, which reward strength (physical and mental), perseverance, and diligence. Some defense scholars have advocated a smarter military, emphasizing intellectual human capital and arguing that cognitive ability will determine success in strategy development, statesmanship, and decisionmaking.2 AI might complement that ability but cannot be a substitute for it. Military leaders must leverage AI to help them adapt and be curious. As innovative technologies with AI applications increasingly become integral to DOD modernization and near-peer competition, senior leaders’ knowledge of AI is critical for shaping and applying our AI strategy and creating properly calibrated expectations.

War is about decisionmaking, and AI enables the technology that will transform how humans and machines make those decisions.3 Successful use of this general-purpose technology will require senior leaders who truly understand its capabilities and can demystify the hyperbole.4 Within current AI strategy development and application, many practitioners have a palpable sense of dread as we crest the waves of a second AI hype cycle, seemingly captained by novices of the AI seas.5 In-house technical experts find it difficult to manage expectations and influence priorities, clouded by buzzwords and stifled by ambitions for “quick wins.” The importance of AI-related education increases with AI aspirations and the illusion of progress. Without that education, we face a world where senior leaders use AI-enabled technologies to make decisions related to national security without a full grasp of the tools that they—and our adversaries—possess. This would be equivalent to a combat arms officer making strategic military landpower decisions without the foundations of military education in maneuver warfare and practical experience.

Strategic decisionmaking in a transformative digital environment requires comparably transformative leadership. Modernization of the military workforce should parallel modernization of equipment and technology. In the short term, senior leaders require executive AI education that equips them with enough knowledge to distill problems that need AI solutions and that provides informed guidance for customized solutions. With the ability to trust internal expertise, the military can avoid overreliance on consultants and vendors, following Niccolò Machiavelli’s warning against dependence on auxiliary troops.6 In the long term, military education should give the same attention to AI that is provided to traditional subjects such as maneuver warfare and counterinsurgency operations. Each steppingstone of military education should incorporate subjects from the strategic domain, including maneuver warfare, information warfare, and artificial intelligence.
