[ti:British Navy Submarine Designs Look Like Real Sea Creatures] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]New images released by Britain's Royal Navy [00:04.64]show how future submarines could look and move [00:09.72]like real sea creatures. [00:13.60]The designs were created by young British engineers and scientists. [00:20.72]They were challenged by the Royal Navy [00:23.92]to imagine how future underwater war machines might look. [00:30.03]The engineers and scientists are members of the group UKNEST. [00:39.04]This not-for-profit organization promotes science, [00:43.91]engineering and technology for British naval design. [00:50.48]The group kept the same requirements used in advanced submarines used today. [00:58.52]But the designers added new technological ideas [01:03.20]to make them easier and less costly to build, [01:07.36]as well as more effective in battle. [01:12.26]Current submarines were designed to perform many roles [01:17.24]as a single piece of equipment. [01:20.84]But the Royal Navy of the future is expected to operate a family of submarines. [01:28.84]This would include many shapes and sizes to carry out different operations. [01:36.76]Some submarines would be manned and others unmanned. [01:42.25]The designs included a "mothership" that would act as a major command [01:48.76]and control center supporting other submarines and ships. [01:55.08]This submarine, with a crew of about 20 people, [01:59.04]would be shaped like a manta ray with wide wings to guide it through the sea. [02:05.54]The futuristic mothership would travel to British-controlled waters worldwide, [02:12.88]docking with other underwater bases. [02:18.40]The future Royal Navy might also use eel-like unmanned underwater vehicles. [02:26.72]The designers imagined these submarines as capable of [02:31.20]curving around objects like an eel and disguising themselves as sea lifeforms. [02:39.38]They could be launched from the mothership and travel hundreds of miles in near silence. [02:48.28]Some of the naval equipment would be engineered with materials [02:52.48]to dissolve after a period of time to avoid being captured by enemies. [03:00.52]One image even shows flying missile weapons [03:04.56]shooting out of the water like sharks or dolphins. [03:10.20]The submarine design project was called Nautilus 100. [03:15.80]It was named after the U.S. Navy's USS Nautilus, [03:20.92]the world's first nuclear-powered submarine. [03:25.53]Britain's Minister for Defense Procurement, Harriet Baldwin, praised the project. [03:34.52]"These remarkable designs display the great promise of our young engineers and scientists [03:41.44]and the great ambition of the Royal Navy." [03:46.84]She added that the futuristic concepts [03:50.40]are an example of what Britain's navy could produce to meet future military challenges. [03:59.52]Commander Peter Pipkin is a robotics officer with the Royal Navy. [04:06.44]He said that with more than 70 percent of the planet covered by water, [04:12.40]there will be more competition between nations in the future [04:16.92]to live and work at or under the sea. [04:22.08]For this reason, he said the Royal Navy is looking 50 years into the future [04:29.00]to find new ways to protect British interests around the world. [04:35.84]"If only 10 perb cent of these ideas become reality, [04:40.52]it will put us at the cutting edge of future warfare [04:44.92]and defense operations," Pipkin said. [04:49.20]I'm Bryan Lynn.
