A Russian spy ship is likely gathering intelligence on Israel's newest submarine, Naval News reported. The submarine, INS Drakon, will be on sea trials following its construction in Germany. According to the report, Russia's Sibiryakov and Wassili Tatischtschew may be gathering intelligence on these trials. Naval News noted that sea trials are "an incredibly sensitive time for new submarines," and that these trials expose them "to unwanted attention from other navies." It is usually easier to gather information during a sea trial than after the submarine is already in service.
