The wreckage of the USS Edsall, an American warship that was sunk during a battle with Japanese forces in World War II, has been discovered more than 80 years after it was lost at the bottom of the sea, U.S. and Australian officials announced Monday. The final resting place of the USS Edsall, a Clemson-class destroyer, was discovered late last year at the bottom of the Indian Ocean, according to the U.S. Navy and Royal Australian Navy. "Working in collaboration with the U.S. Navy, the Royal Australian Navy used advanced robotic and autonomous systems, normally used for hydrographic survey capabilities, to locate USS Edsall on the sea-bed," Chief of Royal Australian Navy, Vice Admiral Mark Hammond, said in a statement. The warship was sunk on March 1, 1942, three months after the attack on Pearl Harbor, during an encounter with Japanese battleships and dive bombers. The USS Edsall was a Clemson-class destroyer, measuring 314 feet in length and capable of 35 knots.

The Russian navy's Black Sea Fleet has been forced to rebase nearly all its combat-ready warships from occupied Crimea to other locations, and its main naval hub is becoming ineffectual because of attacks by Kyiv, Ukraine's navy chief said. Vice-Admiral Oleksiy Neizhpapa said Ukrainian missile and naval drone strikes had caused heavy damage to the Sevastopol base, a logistics hub for repairs, maintenance, training and ammunition storage among other important functions for Russia. "They were established over many decades, possibly centuries. And clearly they are now losing this hub," Neizhpapa told Reuters in a rare interview in the port city of Odesa ahead of Ukraine Navy Day on Sunday. More than 28 months since Russia's full-scale invasion, Kyiv has dealt a series of stinging blows to Moscow in the Black Sea although Ukrainian ground troops are on the back foot across a sprawling front.

Fox News White House correspondent Jacqui Heinrich has the latest on the countries' alliance amid Chinese tensions on'Special Report.' Japan's defense chief Friday called for the bolstering of its anti-drone capability after a drone footage posted on Chinese social media showed a Japanese aircraft carrier docked at a restricted navy port west of Tokyo. Defense Minister Minoru Kihara called it a serious security threat. Kihara's acknowledgement of the vulnerability comes more than a month after a video filmed by a drone showed JS Izumo, one of two Japanese helicopter carriers, being retrofitted to carry stealth fighters to strengthen Japan's counter-strike capability in the face of China's assertive military actions in the Indo-Pacific. The footage, also showing plants, buildings and other facility at the Japan Maritime Self-Defense Force's Yokosuka naval base was posted on a Chinese social media site in March, prompting investigation by ministry officials.

We develop a hierarchical LLM-task-motion planning and replanning framework to efficiently ground an abstracted human command into tangible Autonomous Underwater Vehicle (AUV) control through enhanced representations of the world. We also incorporate a holistic replanner to provide real-world feedback with all planners for robust AUV operation. While there has been extensive research in bridging the gap between LLMs and robotic missions, they are unable to guarantee success of AUV applications in the vast and unknown ocean environment. To tackle specific challenges in marine robotics, we design a hierarchical planner to compose executable motion plans, which achieves planning efficiency and solution quality by decomposing long-horizon missions into sub-tasks. At the same time, real-time data stream is obtained by a replanner to address environmental uncertainties during plan execution. Experiments validate that our proposed framework delivers successful AUV performance of long-duration missions through natural language piloting.

It is, however, naval drones that have made Russia's Black Sea fleet particularly vulnerable. Under relentless attacks, Moscow was forced to withdraw the core of its fleet from Crimea and move them further east, to Novorossiysk. And even there, Russian ships remain within reach of Ukrainian drones.

The United States and United Kingdom carried out more than a dozen strikes against Iranian-backed Houthi targets in Yemen on Saturday, with support from Australia, Bahrain, Canada, Denmark, the Netherlands and New Zealand, two U.S. officials told Fox News. The targets were hit successfully and include weapons storage facilities, and drone and missile launchers. The operation hit five Houthi-controlled locations in Yemen and is a response to the near-daily Houthi attacks involving Iranian drones and anti-ship ballistic missiles, a senior U.S. official said. The fourth round of American and British strikes came days after a British cargo ship was hit by a Houthi missile. In a joint statement, the U.S, U.K. and the other allied countries said: "In response to the Houthis' continued attacks against commercial and naval vessels transiting the Red Sea and surrounding waterways, today the militaries of the United States and United Kingdom, with support from Australia, Bahrain, Canada, Denmark, the Netherlands, and New Zealand, conducted an additional round of strikes against several targets in Houthi-controlled areas of Yemen."

Iraqi forces shot down an armed drone on Tuesday over the Erbil airport in northern Iraq, where U.S. and other international forces are stationed, according to a report. The Kurdistan Counter Terrorism, an Iraqi semi-autonomous regional security agency, said an "illegal militia" launched an armed drone against the Erbil airport that was shot down at approximately 09:52 a.m. It is not immediately clear if the foiled attack caused any damage or casualties. U.S. forces in Iraq and Syria have been attacked more than 90 times since the start of the conflict. The Pentagon does not count attacks on U.S. warships at sea in this number.

NSC Communications Coordinator John Kirby responds to progressive pushback against U.S. aid to Israel on'FOX News Sunday.' Three commercial vessels were attacked in the Red Sea on Sunday, prompting a U.S. warship to shoot down multiple unmanned aerial vehicles (UAV) headed toward them. The development could signify a serious escalation in a series of maritime attacks in the Middle East linked to the Israel-Hamas war. "Today, there were four attacks against three separate commercial vessels operating in international waters in the southern Red Sea," a statement by U.S. Central Command (CENTCOM) explained. "These three vessels are connected to 14 separate nations." The USS Carney was in the southern Red Sea, just north of the Bab al-Mandab Strait, when it shot down three Houthi drones heading in its direction, a U.S. official told Fox News, adding that the action was taken in self-defense. The drones were launched from Houthi-controlled areas of Yemen, the official claimed.

NSC Communications Coordinator John Kirby responds to progressive pushback against U.S. aid to Israel on'FOX News Sunday.' The Pentagon said Sunday a U.S. warship and multiple commercial vessels are under attack in the Red Sea. The development signifies a serious escalation in a series of maritime attacks in the Middle East linked to the Israel-Hamas war. "We're aware of reports regarding attacks on the USS Carney and commercial vessels in the Red Sea and will provide information as it becomes available, later," Pentagon spokesman told Fox News, confirming reports of an attack on a U.S. warship in the Red Sea. The Pentagon initially told the Associated Press, "We're aware of reports regarding attacks on the USS Carney and commercial vessels in the Red Sea and will provide information as it becomes available." USS Carney is a Arleigh Burke-class guided-missile destroyer that has been shooting down drones and cruise missiles in recent weeks launched by Iran-backed Houthi rebels, who claimed credit for Sunday's attack.

A team of Chinese researchers funded by China's People's Liberation Army (PLA) recently claimed to have used artificial intelligence (AI) to design an electrical layout of a warship with 100 percent accuracy and at an unprecedented speed. A team of researchers from the China Ship Design and Research Center, headed by Luo Wei, a senior engineer with the ship design center, published a paper in the Chinese-language journal Computer Integrated Manufacturing Systems on February 27. The researchers claimed in the paper that their AI designer took only a day to complete work that humans would need nearly a year to achieve with the most advanced computer tools. Considering the scale and complexity of modern warships, mistakes are sure to happen during the design process, and it can take several hours to discover and rectify them. However, when the researchers put the AI designer to the test, with more than 400 challenging tasks, they found that the AI could accomplish 100 percent accuracy.
