Chinese ship Yuan Wang 5, which docked in the Southern Sri Lankan port of Hambatota on Tuesday, has irked India. While China claims it is a research vessel, India says that it is a spy ship. In fact, both these claims are true as the Yuan Wang 5 is a classic example of dual-use technology. It possesses sophisticated capabilities that can be used for a wide-range of civilian and military purposes. WION spoke to Aerospace and Defence sources to understand the possible capabilities of such tracking and support vessels.
