The Japan Coast Guard is beginning test flights of an unmanned aerial vehicle to learn whether it can be utilized to carry out the coast guard's key duties, including search and rescue and maritime surveillance.
The flights, which will take place starting Thursday, are to be conducted off the coast of Sanriku in northeastern Japan, as well as along the coasts of the Sea of Japan.
Japan's Defense Ministry will fly an Osprey transport aircraft to Camp Kisarazu in Chiba Prefecture, near Tokyo, on Monday for temporary deployment by the Ground Self-Defense Force, or GSDF.
The Osprey is one of two that have been undergoing maintenance at US Marine Corps Air Station Iwakuni in Japan's western prefecture of Yamaguchi since its arrival in May. The other Osprey will fly to Camp Kisarazu on Friday.
Japanese researchers say they have developed a ceramic material that self-repairs cracks in just a minute and could drastically change manufacturing methods for the transportation industry.
The team from the National Institute for Materials Science (NIMS) and Yokohama National University said the material could be used in plane engines to keep them operating even if they are damaged in collisions with airborne objects.
