#DisruptiveTech 🔴 China unveils submarine detection tech with 12-mile underwater range: innovative device uses seabed electromagnetic signals to extend submarine detection ranges, overcoming traditional limitations posed by seawater. A team of scientists from Shanhgai Tong University in China has allegedly developed a new form of submarine detection that could transform underwater surveillance. The device, which was claimed to have been tested in the depths of the South China Sea, has demonstrated the potential to detect even the quietest submarines over an extended range, a feat that was previously considered impossible. Breakthrough in electromagnetic detection The new detection technology is in a large square-like pickup truck structure, and it uses antennas to detect very weak electromagnetic signals that submarine propellers emit. The recent testing involved a rotating propeller, and the detector successfully identified low-frequency signals at a distance of nearly 12 miles (20 km), according to the South China Morning Post (SCMP). This achievement marks a significant improvement over previous records. Until now, the furthest detection of submarines using similar technology was just over 1.5 miles (2.5 km). a milestone also reached by Chinese scientists. Traditionally, detecting submarines using electromagnetic signals has been a challenge due to the nature of seawater, which tends to weaken electromagnetic waves. As propellers cut through the electric fields surrounding navy vessels, they generate electromagnetic radiation, but these signals are short-ranged in seawater. However, the Shanghai scientists took a different approach—rather than receiving signals from the water, they collected them from the seabed. As a submarine moves, its propellers rotate once per second, creating low-frequency electromagnetic waves that travel into the seabed and spread along rock layers. These waves weaken at a much slower rate in the seabed compared to seawater, allowing the detection range to be greatly extended. The device itself is equipped with instruments and battery compartments for long-term underwater operations, and it is connected to a surface buoy. While primarily designed for submarine detection, the system can also track surface ships by identifying the wake of their propellers. The new technology comes at a critical time when underwater warfare is becoming a key area of focus for major military powers. Submarines have become increasingly stealthy, emitting sounds that are almost indistinguishable from background ocean noise. This poses a major challenge for traditional acoustic detection systems. As tensions in the South China Sea and the Taiwan Strait continue to escalate, both China and the United States are investing heavily in anti-submarine warfare capabilities. #submarine #China #asw Campaign Catapult, Pravo Consulting

Here’s a stroll today through the sunlight-filled flag hallway of the Akasofu Building at the University of Alaska Fairbanks. The hallway connects the Akasofu Building with the Elvey Building, which is home to the UAF Geophysical Institute. The two buildings have a common wall. Although the Elvey Building is the Geophysical Institute’s home, many of its faculty and staff have offices in the Akasofu Building. The Geophysical Institute’s Alaska Center for Unmanned Aircraft Systems Integration, ACUASI, is based in the Akasofu Building. The Akasofu Building is home of the UAF International Arctic Research Center. Flags in the hallway mostly represent Arctic nations and the Danish autonomous territory of Greenland (Kalaallit Nunaat). Here are the national flags in order of appearance in the video (Video by Rod Boyce/Geophysical Institute): South Korea Finland Canada Japan Italy Greenland U.S. Switzerland Iceland Sweden Norway United Kingdom Netherlands Poland Russia Germany China Denmark France

Tech In News : GPS Spoofing & selective availability - Israel reportedly used GPS spoofing against Iran's missile targeting teams by jamming Global Positioning System (GPS) navigation signals. Israel used GPS spoofing against Iran: Did US do it to India in Kargil war? - Ahead of Iran's first-ever direct attack on Israel, Israeli intelligence reportedly jammed the country's GPS navigation system signals to confuse Tehran's missile targeting teams - India's past military operations may have been hindered by the United States (US) using a technique similar to the one reportedly used by Israel to confuse Iran's missile targeting teams by jamming Global Positioning System (GPS) navigation signals in the days leading up to Tehran's overnight attack About 25 years ago, when Pakistani soldiers crossed into India and took positions in Kargil in 1999, the Indian military had sought GPS data for the region, only to be denied by the US, according to a report by an Indian national daily. - Selective availability As explained by a 2021 United States Naval Institute article, the US Department of Defense and Air Force initially employed a technology called "selective availability", which would introduce intentional errors into civilian GPS receivers. This ensured that the best accuracy was retained exclusively for military use. - The article went on to explain that the US used this technology to "degrade" GPS accuracy for the Indian military during the Kargil war, which "hindered Indian operations". Eventually, such actions by the US led India and others to develop their own navigation systems - India went on to build an independent, stand-alone satellite navigation system called NavIC (Navigation with Indian Constellation), developed by the Indian Space Research Organisation (ISRO). NavIC provides precise and secure positioning, navigation, and timing services anywhere in India and 1500 kilometres beyond India's territorial boundary. - . NavIC offers standard positioning services for civilian purposes and restricted services for strategic needs. - However, the GLONASS system, which is an alternative navigation tool to the GPS, is less accurate.The report added that Iran may have been able to bypass Israel's GPS signal jamming attempts to some extent. GPS spoofing: It is also known as GPS simulation, refers to the practice of manipulating or tricking a GPS receiver by broadcasting false GPS signals. It misleads the GPS receiver into believing it is located somewhere it is not, resulting in the device providing inaccurate location data. This form of cyberattack undermines the reliability of GPS data, which is vital for a variety of applications. #upsc #mppsc #upsc #ukpsc #jpsc #cgpsc #ssccgl #ORN

The European Commission will propose several options for promoting research and development (R&D) related to technologies with dual-use potential, namely, those that can be used for both civil and military purposes, such as drones and satellites. The European Union (EU) executive intends to review its current funding programmes to assess whether they provide adequate and strategic support to face the emerging geopolitical challenges outlined in the European Economic Security Strategy. This new approach to R&D related to dual-use technology is detailed in a white paper the Commission is due to publish on 24 January as part of the Economic Security Package. Euractiv obtained an early version of the document. The white paper details several options that will be subject to a public consultation running until 30 April. Stakeholders might request that their submissions, or parts of them, remain confidential given the topic’s sensitive nature. #EU #europeandefence #randd #defencetech Pravo Consulting Campaign Catapult

The #drone war has spread to the #Arctic. Multiple Ukrainian drones were reportedly sent to destroy a Russian long-range supersonic bomber/missile carrier (Tu-22M3) at Olenya air base in the very north of the country. Link: https://lnkd.in/e7HBsPAr This raises questions about Russian air defense and detection in a region that is of great strategic importance to Russia's so-called 'bastion' defense of the Northern Sea Route and most importantly its nuclear deterrence capabilities. The airbase is 1900km from Ukraine, but only 150 km from Finalnd. While there is no suggestion Finland had a role (with the President saying they 'have the situation under control'), Russia is still likely to ramp up pressure on the new NATO member. Link: https://lnkd.in/egM9kQVT While striking targets like this is important for Ukraine to blunt Russia's capacity for long-range strategic bombing, there are broader destabilizing consequences that I discuss in my latest open access article on the increasing use of drones across the Arctic: Link https://lnkd.in/eSvMUV5F

Could the Houthis sabotage undersea cables? Image source, EPA Image caption, The Houthis person been targeting ships successful the Red Sea for respective months By Frank Gardner BBC information correspondent Revenge takes galore forms. The Houthis successful Yemen person made nary concealed of their determination to retaliate against the West for the US-led airstrikes that person been targeting their rocket and drone motorboat sites. These successful crook person been successful effect to much than 30 Houthi attacks connected planetary shipping successful the Red Sea and Gulf of Aden, which they accidental is successful enactment of the Palestinians successful Gaza. The stakes person present been raised. Yemen's legitimate, UN-recognised authorities successful Aden has warned that the Houthis, who seized overmuch of Yemen successful 2014, are present threatening to sabotage the important undersea connection cables, including net lines, which tally nether the Red Sea - connecting Asia to Europe. The informing came aft a transmission linked to the Houthis connected the Telegram messaging app posted a representation showing undersea cablegram routes successful the Red Sea. Could the Houthis sabotage these lines? They astir surely would if they could. The radical has reportedly claimed that they person easy accessed maps showing the confluence of undersea communications cables moving past their coastline, arsenic they walk done the Bab al-Mandab Strait which, astatine its narrowest, is conscionable 20 miles (32km) wide. But the fibre cables, which transportation 17% of the world's net traffic, prevarication connected the seabed mostly hundreds of metres beneath the aboveground - good beyond the scope of divers. The US and Russia are some thought to person the naval capableness to chopped them. This involves deploying a deep-sea submersible from a mothership and past utilizing what are, successful effect, a elephantine brace of scissors for severing the cables connected the water floor. However, it would beryllium much hard for the Houthis to do. "I measure it's a bluff, unless it's an onslaught connected a terminal," erstwhile Royal Navy submarine commandant Rear Adm John Gower says of the claims the radical is threatening to sabotage the cables. "It would request an state with the capability, [someone with] a submersible positive the quality to find [the cables]". The Houthis bash person an state - Iran. With assistance from the Iranian Revolutionary Guard Corps and Hezbollah of Lebanon, the Houthis person built up a formidable arsenal of missiles and drones. Over the past 8 years they person fired these astatine Saudi Arabia, the UAE, Israel, US and British warships - arsenic good arsenic immoderate vas they fishy of links to Israel, the US oregon UK.
