More Batteries vs. Submarines Now that the German TKMS and the French Naval Group have massively adopted lithium-ion batteries, following the Japanese lead, this is consolidating as a major trend, just as I had predicted. The next stage will be solid-state batteries, and at that point, we'll essentially be discussing only speed and submerged endurance in comparison to nuclear submarines. Since solid-state batteries are lighter, they will allow for a greater number to be installed, freeing up space for more powerful propulsion systems. Naval Group has already sold a version of the Scorpène to Indonesia capable of remaining submerged for up to 80 days. That's with lithium-ion batteries. Imagine what this could exceed, more than double, with solid-state batteries. In practical terms, a more powerful engine combined with solid-state batteries in the proportions that Naval Group is now using in the Scorpène would provide three times the speed, meaning something like 10–15 knots at constant speed while maintaining around 50 days submerged. This would give a range of 40,000–50,000 km, requiring less than one hour on the surface for a fast recharge. For speeds above 25 knots, simply adding more batteries and a better engine would suffice, as the solid-state system has high power output. All this at 15–20% of the cost of a nuclear submarine. And if the choice is to power the batteries with a micro-reactor, it would cost 25–35% of a conventional nuclear one. Then someone will say: “But a nuclear sub can stay submerged for years.” That makes no difference at all, since even with around 60 days of endurance, the crew still needs to surface to resupply provisions. The big advantages remain: battery-powered subs are superior in silence, and speed can be addressed with larger battery packs.

HAPPENING NOW: Secretary of War Pete Hegseth just arrived at Castelion to meet with the company’s founders as part of the Department of War 🇺🇸’s Arsenal Freedom Tour. Castelion Corporation is a U.S. defense technology startup founded in late 2022 by former SpaceX engineers, including CEO Bryon Hargis, Sean Pitt, and Andrew Kreitz. The company specializes in designing, testing, and manufacturing affordable, mass-producible hypersonic strike missiles to restore America's conventional deterrence capabilities, particularly against adversaries like China and Russia in hypersonic weapons. Their flagship product is the Blackbeard hypersonic missile system, engineered for high-volume production (thousands per year), lower costs (potentially 10x cheaper than comparable legacy systems), rapid development cycles (months instead of years), and compatibility with existing U.S. military platforms like HIMARS for the Army and various Navy systems. Castelion employs a SpaceX-inspired approach: vertical integration, rapid iteration, high-cadence testing (over 25 flight tests by late 2025), and scalable manufacturing using nontraditional suppliers to cut costs and speed. Castelion is Headquartered in Torrance, California, with facilities in Texas and a major new 1,000-acre solid rocket motor campus in Sandoval County, New Mexico called Project Ranger. The company has secured significant funding, including a $350 million Series B round in December 2025 following earlier rounds, to ramp up production. It has won multiple Department of War 🇺🇸 contracts, including integration awards with the U.S. Army and Navy, SBIR phases, and AFWERX programs for hypersonic development. Castelion aims to address the U.S. lag in hypersonic munitions by focusing on scale and affordability rather than boutique, high-end designs from traditional suppliers like Lockheed Martin Lockheed Martin or Raytheon Raytheon. Upon Pete Hegseth’s arrival, a large screen in the Castelion lobby lit up with a message that read “Welcome Secretary of War Pete Hegseth” and “Arsenal of Freedom” with a video of a missile launch.

Why Having a Satellite Network is So Important In 2023, the Russians were about to close a deal with a certain North Korean MLRS, but the deal fell through exactly because the North Koreans, +20 years ago, had revolted against Russian opposition to their nuclear program and switched from GLONASS to BeiDou. Only few years ago, the NK returned to Glonass and started converting their equipment to work with dual GNSS guidance. But why did the deal sour? Because the Chinese did not authorize the use of their satellites in the Ukraine conflict. The same problem occurred with the Belarusian POLONEZ MLRS, which uses missiles based on Chinese technology. Today, Iran has switched from GPS to BeiDou, aiming for greater resistance to jammers and integration with Chinese systems. This shows that a missile program is much more than the missiles themselves. It is necessary to have one's own constellation, even if it is strictly military and regionalized, with resources for monitoring and target acquisition, in addition to the ability to deal with jammers and spoofers. When I mentioned Iran and BeiDou, it is the beginning and serves as a gateway that enables integration with Chinese networks, provided the Chinese decide to allow it. However, it is essentially a massive gateway, with numerous smaller, more specialized sub-channels operating underneath. For targeting moving objects, Iran would need to receive data from the Guowang or Yaogan networks. In the last six months, the Chinese could have provided partial integration. At this stage, since the Iranians are conducting their ISR primarily with drones, I believe the Chinese are not sharing data from the LEO satellites in those networks. Iran also has its own satellites, but the Chinese network is far more mature and likely equipped with a wide array of integration and data-sharing tools. While the Chinese are providing intelligence to Iran, I believe they are prudent in doing so to preserve the relationships they have built with other Arab states. At this moment, I believe that the sharing of intelligence from satellites isn’t in real time. For a country like Iran, it is crucial to have GNSS independence with its own program. The same applies to other medium-sized countries, which need at least an LEO constellation capable of providing the minimum ISR, and this is linked to security, but also a series of other factors. I'll give a practical example here. Drones usually lose link with 50% of their range in the Amazon due to weather conditions. With an LEO constellation, this would not occur. Today, to have independence, a constellation project is necessary.

Those investing in submarines today may be wasting money. A Virginia-class submarine, powered by an S9G reactor, has a submerged displacement of around 10,000 tons and costs approximately $4–5.8 billion. Its top speed is over 30 knots. Now imagine a much smaller reactor, with power and weight around 15% of the Virginia's, used solely to continuously recharge a solid-state battery bank. Solid-state batteries weigh about half as much as lithium-ion batteries while offering 2-3x more energy capacity. In practice, this means that with the same battery weight, such a sub could achieve roughly 3x the energy gain, In terms of speed, solid-state batteries deliver double or higher discharge rates (potentially 10–20C vs. 5–10C for lithium-ion), ideal for sustained sprints above 30 knots lasting many days and a cruising speed around 25 knots. All this with 15% less overall weight, much quieter operation on batteries alone, and the same endurance as a conventional nuclear sub. And the cost? A micro-reactor would be 15–25% the price of a conventional one, small, modular, low-temperature/low-pressure. This means that when a more modern reactor is needed, you simply swap the module. A micro-reactor paired with solid-state batteries could make a Virginia-class sub $1.2-1.6 billion cheaper, quieter, and leave far more space for weapons, additional batteries, or crew comfort. That's why this system would put all existing submarines at a disadvantage in terms of cost, space, and stealth. Those not adopting micro nuclear reactors can follow what the Germans, Japanese, and French are doing. The Japanese pioneered lithium-ion batteries with diesel chargers, giving their submarines excellent value for money. The Germans chose a fuel cell AIP system to recharge lithium-ion batteries, while the French opted for a similar Japanese-style approach with a battery configuration allowing up to 80 days endurance, making the new Scorpène highly competitive. Starting around 2030, production will shift to solid-state batteries, tripling the capacity of these conventional submarines and enabling silent navigation at around 25 knots for days,making them superior in stealth and speed to many nuclear submarines currently in service. Submarines powered by solid-state batteries, recharged via micro-reactors, fuel cells, or diesel, will be superior: better armed, cheaper, and stealthier than anything we know today.

It has been a privilege to collaborate with Amanda Davies and Ghaleb Krame, Ph.D. on research that explores one of the most significant emerging security challenges of our time. We are honored that our paper, “A Framework for Predicting Adoption of AI-Enabled Autonomous Drone Capabilities by Transnational Organized Crime and Foreign Terrorist Organisations”, has been accepted for presentation at EMCIS 2026, the 23rd European Mediterranean & Middle Eastern Conference on Information Systems, to be held in Paris this August. What makes this particularly meaningful is that the research was completed and submitted well before the issue entered the center of public policy discussions in Washington. Our study examined the pathways through which transnational criminal organizations could evolve from conventional drone operations toward increasingly autonomous and AI-enabled capabilities. Using structured comparative analysis and open-source intelligence, it identified conditions under which such technological adoption could accelerate. Just on June 2, 2026, during testimony before the U.S. Senate Foreign Relations Committee, Secretary Marco Rubio warned that Mexican cartels are already employing drones and that these capabilities could ultimately threaten U.S. interests. While academic research does not seek to predict headlines, its purpose is to identify emerging risks before they become strategic realities. The growing attention from policymakers underscores the importance of rigorous, evidence-based analysis at the intersection of artificial intelligence, autonomous systems, and transnational security. We are grateful to the EMCIS reviewers and organizers for recognizing the contribution of this work and for fostering serious discussion on challenges that will increasingly shape the security landscape of the coming decade. I am proud to serve the interests of the United States through research and analysis focused on the evolving capabilities of Mexican cartels. Working alongside Dr. Ghaleb Krame, Ph.D. , it is a privilege to contribute to a deeper understanding of emerging security threats and to support informed decision-making in an increasingly complex technological and geopolitical environment.

🔬 Why Perfect Visualization of Stents and Calcified Plaques Requires the Highest Spatial, Temporal and Contrast Resolution: The Case for Ultra-High-Resolution with Photon Counting CT Image: a close look at a RCA stent with very mild intimal hyperplasia. Seeing is everything in coronary imaging. Yet when it comes to stents and heavily calcified plaques, even the best conventional CT systems hit their physical limits — blooming, partial volume effects, and metal artifacts blur what truly matters. That’s where Ultra-High-Resolution Photon Counting CT (PCCT) changes the game. 🧠 Why it matters: Conventional CT often overestimates stenosis in calcified vessels and hides in-stent lumen due to blooming and noise. This leads to diagnostic uncertainty, unnecessary invasive testing, and poor evaluation of stent patency or neo-atherosclerosis. ⚡ What PCCT adds: Ultra-high spatial resolution (0.1 mm voxels) sharply delineates stent struts, plaque borders, and residual lumen. True spectral resolution minimizes blooming and metal artifacts, enhancing visualization even in highly calcified segments. Improved contrast-to-noise enables clear lumen assessment at lower doses. Quantitative, energy-resolved data provide material differentiation between calcium, metal, and contrast — something previously unthinkable in CT. In short, accurate visualization of stents and calcified plaques demands Photon Counting CT — not just for sharper images, but for better diagnostic confidence and patient management. The era of artifact-free coronary imaging has begun — and it’s photon-counting powered. ⚡❤️ #PCCT #CardiacImaging #CoronaryCT #StentImaging #CalciumScore #PhotonCountingCT #PrecisionImaging #CardiovascularImaging #RadiologyInnovation #yesCCT

Bengaluru airport outrage: Passengers fume as KIA's compel them to trek 800 meters for cabs; flyers irked by kerbside clampdown What feels worse after a long flight- sitting inside the aircraft or walking for nearly 800 metres with luggage to board a private pre-booked cab? For hundreds of passengers arriving at Kempegowda International Airport (KIA) over the past few days, the answer has been unequivocal the long walk.Bengaluru International Airport Ltd's newly enforced traffic management and kerbside pick-up policy at Terminal 1 (T1) and Terminal 2 (T2) has triggered widespread frustration among passengers and cab operators alike. Rolled out to curb illegal parking, touting, and congestion outside arrival terminals, the policy allows only airport-authorised aggregator taxis to pick up passengers directly from the kerbside.All other private pre-booked cabs including long-distance and outstation taxis have been shifted to designated pickup zones at parking areas P3 and P4, nearly 800 metres from T1. For tired travellers, the new arrangement often means a 15-17 minute trek after landing, navigating elevated walkways, ramps, long corridors, and multiple elevators - all the while hauling heavy luggage. Senior citizens, parents with young children, and families have been hit the hardest, with many describing the change as insensitive and poorly thought out. At T1, arrivals now face a complex lane system: the first lane is reserved for govt vehicles, the second for airport aggregator taxis, the third to fifth lanes for private white-board vehicles, and the remaining lanes for premium app-based services. While passengers opting for airport taxis can step straight into their vehicles, those who have booked private cabs must make the long walk to reach their drivers. At T2, the issue has taken a different form: a strict time window that many say is nearly impossible to meet.Monday morning saw visible chaos at both terminals, with confused passengers asking for directions, pre-booked private cab drivers arguing with security personnel, and tempers flaring. Several travellers complained that the policy was implemented without adequate public communication or a transition period. "We landed around noon and were suddenly told our cab couldn't come anywhere near the terminal. My parents are elderly, and my mother has knee problems. Making them walk nearly a kilometre was extremely stressful," said Rakesh Sharma, a first-time visitor to Bengaluru from Jaipur who had pre-booked a private cab. Another passenger, Anita Fernandez, who arrived from Goa with her two children, said the experience was exhausting. "After paying airport charges and cab fares, you expect some convenience. Instead, we were made to walk endlessly, with hardly staff to guide us #bangalore #bengaluru #blrairport BLR Airport ಬೆಂಗಳೂರು ನಗರ ಪೊಲೀಸ್‌ BengaluruCityPolice ಬೆಂಗಳೂರು ಸಂಚಾರ ಪೊಲೀಸ್ BengaluruTrafficPolice CP Bengaluru ಪೊಲೀಸ್ ಆಯುಕ್ತ ಬೆಂಗಳೂರು Joint CP, Traffic, Bengaluru alok kumar DGP KARNATAKA ಕರ್ನಾಟಕ ರಾಜ್ಯ ಪೊಲೀಸ್ Karnataka State Police S.
