The world's leading technology and automobile companies have already competed in the run of self-driving cars. Now self-propelled vehicles are being added to automobiles.
US Defense Advanced Research Projects Agency (Darpa) has built self-propelled war ships for passenger transport. This self-propelled ship may be used to follow enemy submarines soon, as has been said in CNBC's report.
The name of the new ship is called "Sea Hunter". After several successful tests, the US Navy sent a prototype to Darpa.
The ship can continue for several months without any sailor. The 132-foot length of C Hunter will be running at a maximum speed of 27 nautical miles, the report said.
Since 2012, the work was going on to build the ship. It has cost US $ 20 million to build.
Drappa said that the ship could be operated by the end of this year.
