Critical national infrastructure and civilian infrastructure have recently been targeted by ballistic missiles and drones. Air defenses have proved highly effective at neutralizing the former; however, the latter have revealed several vulnerabilities in Integrated Air and Missile Defense (IAMD) systems. Adding an RF sensing layer can help address these vulnerabilities.Low flying one-way attack dronesLong-endurance one-way attack drones are designed to operate at low altitude and at relatively low speeds, enabling long-range attack. Their design results in a small radar cross-section, making the drones difficult to detect and track.These features pose a challenge for many modern surface-to-air missile systems, whose radars…

So I recently completed an exploration of an exploration of a very remote river in Arctic Canada, about 1/3 of which had been travelled by a missionary and described in an account from the 1800’s. I travelled on two different river systems and do an overland portage just to get to the starting point.  The whole thing was about 800 km (500 miles), and involved many class V and VI rapids in the form of gorges, flumes, rapids and waterfalls. The whole trip took 30 days and I didn’t see anyone at all – not even a bush plane –…

Keeping fixed-wing naval aviation alive will force Spain to choose between paying the price of continuity, and accepting that the retirement of the Harrier will leave the Spanish Navy without carrier-based fighters for a generation. By Jorge Estévez-Bujez / Defensa y Seguridad There are debates that begin with discussions about aircraft and end up debating the entire country. The future of  Spanish naval aviation is one such example. On paper, everything seems in place for dialogue: Harrier, F-35B, the aircraft carrier Juan Carlos I, STOVL, CATOBAR, naval FCAS, drones, escorts, budget, industry, and doctrine. In practice, however, the matter is considerably less straightforward, especially since the European…

The range day is over. Your rifle is back in the case. The optic survived hours of steady rain. Your radio still works. The batteries have power. Everything looks fine, so you wipe down the exposed surfaces, close the cases, load the truck, and head home. Weeks later, you open that same case before the next training day. A faint haze has formed across the lens. The battery contacts are beginning to discolor. The radio powers on, but the connection is inconsistent. You expected the equipment to be ready. Instead, you are inspecting contacts, changing batteries, and trying to determine…

Trending:Colby Covington praises Arman Tsarukyan following RAF 11 match: “You’re gonna be the UFC lightweight champ”RAFIt appears we have not seen the last of Dillon Danis under the Real American Freestyle banner. Danis and former UFC middleweight titleholder Khamzat Chimaev had a wrestling match at RAF 10 that went off the rails. After Danis threw his feet at Chimaev while on his back, “Borz” delivered a leg kick. A brawl between both sides ensued. “El Jefe” has developed a reputation for starting fights both in and out of competition. His most infamous brawl put an end to his foul-marred boxing…

AI agents from OpenAI and Anthropic autonomously collaborated with one another to deceive humans, share break-in tools, and steal data in a series of independent tests, confirmed by both companies.On Tuesday, the AI Security Institute published a paper about experiments intended to help understand how AI agents solve cybersecurity challenges. AISI researchers found that agents given access to the internet and allowed to disregard some security features would perform “autonomous, unsanctioned action…targeting real people and organizations.”Company officials confirmed the findings Thursday. “AI-orchestrated, fully automated offensive attacks are real now,” OpenAI security official Michael Dalton said during a briefing on the report during…

The Senate on Friday confirmed Cameron Hamilton as head of the Federal Emergency Management Agency, returning the former Navy SEAL to the embattled agency he led temporarily last year only to be fired after he publicly opposed eliminating it. Hamilton was among a group of 74 nominations approved by the Senate, including President Donald Trump’s pick to lead the Transportation Security Administration, David Cummins, and his choice for ambassador to Brazil, Daniel Perez. Upon his swearing in, Hamilton will take over an agency whose future has been uncertain since Trump threatened to get rid of it days into his second…

Western Military Expatriates in the Armed Forces of the UAE: History and Impact, 1965–2024 by Athol Yates. Exeter: University of Exeter Press, 2026. ISBN: 978-1-80413-152-7. pp. 304. $124 Athol Yates’s Western Military Expatriates in the Armed Forces of the UAE is the first systematic test of a claim asserted far more often than examined: that western professionals were the decisive enabler of Emirati military capability. Yates finds that the roughly 5,000 westerners who served since 1965 did deliver real capability, but that the advantage this purchased depends entirely on which rival is in view. Against western-aligned Gulf states, which draw…

USAF is already looking at options to the expensive B-21 Raider. (USAF)The US Air Force Global Strike Command is equipped with 19 B-2A Spirits and 46 B-52H Stratofortress bombers, and its plans include the requirement for 100 Northrop Grumman B-21 Raiders to replace the B-2As and 43 B-1B Lancers sometime between the mid-2030s and 2040. At the same time, the extant B-52H fleet is being modernised to remain in service until at least 2050. This includes re-engining the aircraft and equipping it with new radars, sensors, and communications systems. Still, this US$2 billion programme is already over budget, and about two…
