China Develops Deep-Sea Cable Cutting Device, Raising Security Concerns

Low-cost drone accessories from Chinese e-commerce platforms such as Temu and AliExpress are raising concerns about the potential for mainstream quadcopters to be easily converted into weapons. Researchers from Red Balloon, a security firm, have discovered various add-ons including AI-guidance modules and long fiber optic tethers, which can allow users to operate drones beyond the range of signal jammers. These technologies have been observed in the Russia-Ukraine conflict, and similar items can be purchased for less than $300. Ang Cui, CEO of Red Balloon, expressed alarm over how inexpensive these products have become, emphasizing that they can empower anyone, from criminal groups to individuals with malicious intent, to conduct violent acts. "These are toys that are really amazing at killing people," Cui stated. The alarming ease of access to military-grade drone technology highlights the need for regulatory measures. However, Alibaba and Temu have yet to comment on the potential risks posed by these accessories. As the situation evolves, experts warn that weaponized drones may present significant threats to public safety.

China has declared its readiness for "any type of war" with the United States in response to President Donald Trump's escalating trade tariffs. The two nations are inching closer to an economic conflict, with Trump recently imposing additional tariffs on all Chinese imports, prompting Beijing to retaliate with 10-15% tariffs on U.S. agricultural products, according to statements from China's embassy reposted on social media. In a speech at the National People's Congress, Premier Li Qiang emphasized the government's focus on increasing defense spending by 7.2% this year, while asserting that China remains confident in its economic growth despite external pressures. As reported by Reuters, this increase is part of China's broader strategic initiative amid claims that the U.S. is attempting to shift blame for the fentanyl crisis onto China. The statement also expressed Beijing's condemnation of what it sees as U.S. bullying tactics, asserting that intimidation will not deter China. Analysts suggest that while China maintains a military budget of $245 billion, it may underreport actual defense spending. As tensions rise, both nations' leaders are grappling with complex geopolitical challenges that could affect global markets.

Chinese researchers have reportedly made significant advancements in rocket propulsion technology that could lead to the development of stealth missiles capable of midair speed adjustments and evasion of detection systems. According to a study published in the journal Acta Aeronautica et Astronautica Sinica, the new engine design utilizes helium gas mixed with fuel in a unique way that enhances propulsion efficiency and reduces leak risks, as reported by Interesting Engineering. The innovation reportedly stems from issues encountered with Boeing's Starliner spacecraft that affected NASA astronauts stranded on the International Space Station in June 2024. The researchers aim to create a propulsion system capable of generating over three times the thrust compared to traditional engines. Furthermore, their design produces exhaust significantly cooler than current alternatives, potentially rendering missiles nearly invisible to tracking technologies. While the technology has yet to be tested in practical applications, its implications for both military capabilities and cost-effective space exploration are considerable. This development aligns with China's broader ambitions in aerospace, including plans for advanced lunar expeditions.
