Radioflash! Episode-8: Israel, Hamas and the Electromagnetic Spectrum

You have heard of hard kill, you have heard of soft kill, but what about SMART Kill? Drawing on his operational experience in the Royal Navy, and time in industry, Alasdair Gilchrist, our guest on episode 16 of Radioflash! says we need to start thinking about how to engage threats without stovepipes. Mr. Gilchrist, who has recently embarked on a new career as a consultant, has developed the SMART (Sensors and Measures Against Realistic Threats) Kill concept of operations. This takes the effects-based approach to prosecuting threats a step forward. He argues that traditional thinking about hard kill and soft kill approaches are becoming obsolete. The plethora of emerging threats militaries are facing, the Uninhabited Aerial Vehicle (UAV) menace being a good example, is forcing this rethink. Within the SMART Kill concept, sensing stresses the importance of threat comprehension. Are we understanding the real, and not the perceived, threat? This is particularly relevant on future battlefields where misinformation and disinformation risks clouding our threat sensing and comprehension. When engaging a threat, are we using our effects judiciously and responsibly? Should we be sending kinetics aloft to counter UAVs, when jamming may kill such threats just as effectively? The danger posed by swarms of UAVs aptly underscores this point. Can the SMART Kill approach allow us to use technologies which may not be exquisite, but which may perform the mission just as well, but at a fraction of the cost?

The US and her allies are embracing the Multi-Domain Operations philosophy with the Joint All Domain Command and Control System is at the heart of this endeavour. Multi-Domain Operations, or MDO, focus on improving the pace and quality of decision-making at the expense of one’s adversary. The goal is to navigate the famed OODA (Observe, Orient, Decide and Act) loop at a faster clip than your enemy. Get MDO right and you will always be proactive while your opponent is forced to be reactive. JADC2 The Joint All Domain Command and Control architecture, or JADC2, is the US Department of Defence’s networking and computing project that will enable MDO. JADC2 will see the inter- and intra-force connection of all personnel, weapons, sensors, platforms, subsystems and capabilities at all levels of war. The undertaking is ambitious. Reports say that since 2022 the Pentagon has spent up to $2.6 billion on JADC2. A further $9 billion could be spent on the initiative before the end of the decade. In episode 15 of Armada’s Radioflash! podcast we talk to Leslie Hulser, executive vice president, corporate strategy of Persistent Systems. We examine the status of JADC2, what this overarching effort has achieved to date, potential problems and shortcomings, and the work that still needs to be performed.

Estonia is experiencing the challenges of Russian hybrid warfare first hand and is most likely in the direct path of any future military action by Moscow to reconstitute the former USSR. Estonia is on the frontline of efforts by the Russian government to destabilise the governments, economies and societies of the Baltic nations. Like her other Baltic neighbours, the invasion and occupation of Estonia will be key to any future attempts by Russia’s president Vladimir Putin to rebuild the former Soviet Union. So-called ‘sub-threshold’ actions by Moscow, which aim to amplify destabilisation but are short of outright war, are occurring in the electromagnetic spectrum. Estonia has witnessed recent disruption to civil aviation strongly suspected to have been caused by Russian GNSS (Global Navigation Satellite System) jamming. GNSS jamming has also caused disruption to everyday life in Estonia. Ride sharing services and food deliveries are two consumer services affected by Russian GNSS attack. At the same time, Estonia has faced regular and significant state-sponsored Russian cyberattacks. Barring a major political change in Russia, there are few signs that Moscow’s hybrid warfare against Estonia will cease any time soon. However, it is not all bad news. Domestic science and technology ingenuity is playing its part. Estonia has world-class innovation focused on nullifying and reducing the severity of nefarious Russian actions in the spectrum. Tallinn’s strategy writ large is not just to prevent Russian invasion but to deter it. In this latest edition of Armada’s Radioflash! podcast we chat about these and other issues with John Longhurst, chief executive officer of Tangent Link and longtime Estonian resident.

Artificial intelligence and machine learning are two much-heralded technologies set to revolutionise signals intelligence collection, processing and dissemination. An increasingly congested radio spectrum is set to challenge the limits of human cognition in the search for the signal of interest. In this episode of Radioflash! we catch up with Patrick ‘Krown’ Killingsworth, EpiSci’s  director of autonomy projects. We define the terms Artificial Intelligence (AI) and Machine Learning (ML) and their unique capabilities. ML algorithms are trained on huge amounts of data which makes these algorithms great for processing huge amounts of data, a key requirement in Signals Intelligence (SIGINT). The application of AI and ML in SIGINT is not necessarily about replacing the human but helping the SIGINT operator sort these data. Nonetheless, the continuing introduction of AI and ML into SIGINT analysis prompts concern and enthusiasm in equal measure. Ensuring that enough data are available for training algorithms creates challenges given the paucity of data which the SIGINT cadre may be interested in. We talk about the risks of using synthetic data for training and tackling the risk by anticipating potential problems from the start. AI- and ML-enabled SIGINT systems continue to get smarter, faster and more accurate. The future brings challenges in terms of moving this SIGINT technology from the strategic level to the tactical edge, although edge computing in the tactical domain should help no end in this regard.

The modern electromagnetic battlespace is becoming more distributed, more mobile and more lethal. As neer-peer adversaries continue to develop and deploy advanced electronic warfare capabilities – the ability for the warfighter to communicate and share data to achieve decision dominance in contested environments is mission-critical. Silvus Technologies Jimi Henderson joins Armada’s military communications webpage and monthly newsletter editor Dr. Thomas Withington on this special podcast to explore these dynamic challenges. Learn how Silvus Technologies is responding with new & uniquely integrated MANET radio solutions, manned/unmanned systems teaming and advanced LPI/LPD and Anti-Jamming resiliency capabilities that are empowering the warfighter to achieve Spectrum Dominance at the tactical edge.

The importance of space as a domain of warfare is deepening. Since the dawn of the space age in the 1950s, militaries have exploited space for communications, espionage and strategic attack. Despite the end of the Cold War in the early 1990s, military demand for space is as strong as ever. The assertiveness of the People’s Republic of China and Russia is making space ever more strategically important. Expanding global military interest in the cosmos is impacting the electromagnetic environment. Actors seek to preserve access to their space-based assets while denying this to their rivals. In this latest episode of the Radioflash! podcast we are joined by Juliana Suess, a research fellow studying space security at the Royal United Services Institute defence and security thinktank in London. We discuss counterpace weapons, both kinetic and electronic, and their long history. The influence of cyberwarfare as a counterspace weapon also falls under our gaze. We examine the changing nature of counterspace warfare and the fact that attacks may no longer only be the preserve of nation states. We tackle the use of space Electronic Warfare (EW) during the ongoing war in Ukraine, and Russian capabilities. Moreover, the influence of GNSS (Global Navigation Satellite System) jamming forms part of our discussion. We also talk about the steps that state and non-state actors can take to reduce their risks from space EW.  

Tim Elliott, Head of Sales and Business Development, and Rob Hall, Product Management Lead at L3Harris in Tewkesbury and Fleet join Dr. Thomas Withington to address the many challenges presented by small UAS threats in today’s battlefield and explore how L3Harris’ CORVUS C-sUAS capabilities are helping to support such missions.

One of the Cold War’s great ‘what ifs?’ was whether the United Kingdom’s V-Bomber nuclear deterrent force would have been able to reach and attack its targets in the Soviet Union. In the 1950s and ‘60s, the Royal Air Force’s V-Bomber fleet was the custodian of Britian’s nuclear deterrent. A trio of aircraft, namely the Vickers Valiant, Handley Page Victor and Avro Vulcan series strategic bombers were all tasked to deliver nuclear weapons of varying yields to targets in the Soviet Union (USSR). Should the Third World War have broken out, these aircraft would have flown to their aimpoints in the USSR across what was arguably the most heavily defended airspace in the world. How likely was it that these aircraft would have reached their targets, delivered their nuclear weapons and escape unscathed? Would the electronic countermeasures carried by these aircraft have successfully defended them against Soviet radar? Could the V-bombers adequately jam the radio communications Soviet air defences depend upon? A new book by historian Dr. Tony Redding, entitled V-Bombers on Britain’s Nuclear Frontline, lifts the veil on aspects of the V-Bomber force that have hitherto been shrouded in mystery. In this Radioflash! podcast he joins us to tackle such questions and to share other results of his research on the UK’s nuclear deterrent. More details of Dr. Redding’s publications can be found on his website.

Diamonds have attributes which are useful for current and future defence electromagnetic applications such as quantum communications and navigation. Diamonds have the highest thermal conductivity of any solid material making them particularly suitable for environments where temperature management is paramount. Electronic warfare, radar and military communications all depend on power amplifiers to transmit radio frequency energy. The more power you send through these amplifiers, the more effective these systems become. However, this can come with a heat penalty making the temperature tolerances of diamonds particularly useful. Furthermore, diamonds are well-placed to contribute to the emerging field of quantum communications where individual defects in the material, commonly known as flaws, help such applications. Diamonds with specific defects to support quantum communications can be produced on demand. Defects can also support quantum sensing applications, notably magnetic field sensing. Magnetic field sensing could support navigation applications not depending on Global Navigation Satellite System constellations. Element6 produces synthetic diamonds and details on how these are formed can be found here. The company is involved in a Defence Advanced Research Projects Agency (DARPA) initiative called LADDIS (Large Area Device-quality Diamond Substrates). LADDIS is examining ways in which laboratory-grown diamonds can be used in microelectronics. If you want to learn more about the role diamonds play in defence electromagnetics? Tune in to our latest Radioflash! podcast. We will be chatting to Ian Friel, Element6’s business development programme manager and principal scientist Andrew Edmonds.

Israel’s ongoing military operations in the Gaza Strip have once again highlighted the perils and pitfalls of urban electronic warfare, much as US-led operations in Iraq did several years earlier. In episode 8 of the Radioflash! podcast, we chatted to Colonel Jeffrey H. ‘Fish’ Fischer, a European and global security expert, and author of the Curt Nover series of thrillers. Fish talked about the Electronic Warfare (EW) implications of Israel’s ongoing war in the Gaza Strip. This discussion generated significant interest and prompted an old friend of the podcast, Major Erik Bamford, to get in touch. Maj. Bamford is the Norwegian Armed Forces’ staff officer for electronic warfare and the Association of Old Crows’ director of region 1. Region 1 covers Africa, Europe and Middle East. In this episode, we discuss the unique challenges inherent in performing EW in built-up areas. Maj. Bamford outlines the current state-of-the-art regarding the general literature on urban warfare. He talks about the place of electronic warfare within wider theories and approaches to urban combat. It is noteworthy, he says, that there is a paucity of dedicated texts looking at the peculiarities of EW in built-up areas. The examination of urban EW has tended to focus on electronic warfare’s role in the counter-improvised explosive device battle. Meanwhile, troops must fight in a complex built-up environment home to hundreds of thousands, if not millions, of Radio Frequency (RF) emitters. To further complicate matters, radio waves have strange behaviours in urban environments, bouncing off hard surfaces and working badly underground. Certain building materials either reflect or absorb RF in particular ways. These phenomena only serve to further complicate the EW cadres’ work in the urban environment. Maj. Bamford is keen to work with other EW practitioners who share his interest in urban electronic warfare and he can be contacted via the Armada website.
