CNBC reports that U.S. airlines have "canceled hundreds of flights to airports in Puerto Rico and Aruba, according to flight tallies from FlightAware and carriers' sites." JetBlue, Southwest, and American Airlines were among the multiple airlines showing cancelled flights, which "included close to 300 flights to and from San Juan, Puerto Rico's Luis Muñoz Marín International Airport, more than 40% of the day's schedule, according to FlightAware." Airlines canceled flights throughout the Caribbean on Saturday following U.S. strikes on Venezuela after the Federal Aviation Administration ordered commercial aircraft to avoid airspace in parts of the region.... It wasn't immediately clear how long the disruptions would last, though such broad restrictions are often temporary. Airlines said they would waive change fees and fare differences for customers affected by the airspace closures who could fly later in the month. CNN cites a U.S. official who says more than 150 U.S. aircraft (including helicopters) launched from 20 different bases "on land and sea" during Friday's attack. The U.S. has said the lights were out in Caracas during the attack, presumably because of a targeted strike on their power grid. "Videos filmed by Caracas residents showed parts of the city in the dark," reports the Miami Herald. United Nations secretary-general António Guterres issued a statement via his spokesman saying he was "deeply concerned that the rules of international law have not been respected," (according to a Reuters report cited by the Guardian). The Guardian adds that "a number of nations have called for an emergency meeting of the UN Security Council, in New York, today, as a result of the U.S.'s unilateral action."

Israel has operationally deployed Iron Beam, a 100,000-watt laser air-defense system capable of shooting down drones, rockets, and mortars at negligible per-shot cost. According to Tom's Hardware, it marks the first real-world deployment of a high-energy laser as part of a modern, multi-layered missile defense network. From the report: The Iron Beam is a short-range line-of-sight laser interceptor that is extremely cheap to run and, therefore, perfectly suited for intercepting low-cost, high-volume threats. According to the official Israeli announcement, Iron Beam systems have "successfully intercepted rockets, mortars, and UAVs." A complex mix of government, military, scientific, and commercial interests were responsible for the research and development of the Iron Beam laser system. Central to the Iron Beam are "an advanced laser source and a unique electro-optical targeting system, enabling the interception of a wide range of targets at an enhanced operational range, with maximum precision and superior efficiency," boasted the press release by Israel's MoD. Moreover, it works "at a negligible marginal cost, which constitutes the laser system's primary advantage." We don't get much more by way of technical details, perhaps understandably. However, Rafael Advanced Defense Systems execs heralded the system's "unique adaptive optics technology," in what it calls "the world's most advanced laser-based system for intercepting aerial threats." Its operational debut "marks the beginning of the era of high-energy laser defense," they claimed.

An anonymous reader shared this report from the Wall Street Journal: Sending drones and robots into battle, rather than humans, has become a tenet of modern warfare. Nowhere does that make more sense than in the frozen expanses of the Arctic. But the closer you get to the North Pole, the less useful cutting-edge technology becomes. Magnetic storms distort satellite signals; frigid temperatures drain batteries or freeze equipment in minutes; navigation systems lack reference points on snowfields. During a seven-nation polar exercise in Canada earlier this year to test equipment worth millions of dollars, the U.S. military's all-terrain arctic vehicles broke down after 30 minutes because hydraulic fluids congealed in the cold. Swedish soldiers participating in the exercise were handed $20,000 night-vision optics that broke because the aluminum in the goggles couldn't handle the minus 40 degree Fahrenheit conditions.... An arctic conflict would force war planners back to basics. Extreme cold makes the most common components brittle. Low temperatures alter the physical properties of rubber, causing seals to lose their elasticity and leak. Traces of water or humidity freeze into ice crystals that can scratch pumps and create blockages. Wires should be insulated with silicone rather than PVC, which can crack. Oil and other lubricants thicken and congeal. In most standard hydraulic systems, fluid becomes syrupy and can affect everything from aircraft controls to missile launchers and radar masts. A single freeze-up can knock out an entire weapons platform or immobilize a convoy. Even the Aurora Borealis interferes with radio communications and satellite-navigation systems, according to the article.

A bipartisan right-to-repair provision that would let the U.S. military fix its own equipment faces a serious threat from defense industry lobbyists who want to replace it with a pay-per-use model for accessing repair information. A source familiar with negotiations told The Verge that there are significant concerns that the language in the National Defense Authorization Act will be swapped out for a "data-as-a-service" alternative that would require the Department of Defense to pay contractors for access to technical repair data. The provision, introduced by Sens. Elizabeth Warren (D-MA) and Tim Sheehy (R-MT) in their Warrior Right to Repair Act, passed the Senate in October and has support from Defense Secretary Pete Hegseth, the Army and the Navy. The National Defense Industrial Association published a white paper backing the data-as-a-service model, arguing it would protect contractors' intellectual property. Reps. Mike Rogers (R-AL) and Adam Smith (D-WA), who lead the House Armed Services Committee, outlined similar language in their SPEED Act. Rogers received more than $535,000 from the defense industry in 2024; Smith received over $310,550. The final NDAA is expected early next week.
