Global Times reported on November 7 that a new generation of unmanned anti-submarine "Marine Hunter" has begun a series of intensive tests in the Pacific Ocean since arriving at Pearl Harbor on October 31 as a weapon to restrain Chinese and Russian submarines.
According to the report, Major Tim Gorman, spokesman for the US Pacific Fleet, revealed that the series of tests were conducted by the Naval Research Office to demonstrate the reliability and endurance of the Marine Hunter, which is also part of the establishment of a "new naval system". The report said that the unmanned craft is 40 meters long and has 140 tons of drainage. It can plan its route independently and avoid obstacles at sea by relying on onboard sensors and navigation systems. It can sail for up to 10,000 nautical miles continuously. Compared with the maintenance cost of the traditional destroyer, which is as high as $700,000 a day, the "Sea Hunter" costs only $15,000 to $20,000.
The U.S. Navy envisages that in the future, many "sea hunters" equipped with anti-submarine equipment can form a large net to search for enemy submarines in thousands of square kilometres, running for months without rest. "Sea Hunters" can protect ports and monitor other sensitive sea waters 24 hours a day and 7 days a week. The U.S. military believes that Chinese and Russian submarines are becoming increasingly active, so "sea hunters" are assigned priority to the Pacific Ocean for testing. (Wu Yan)
