INS Dhruv

INS Dhruv (A40) is a research vessel and missile range instrumentation ship built by India's Hindustan Shipyard Limited (HSL). The ship was earlier only known by its shipyard designated yard number as VC-11184. The ship can gather electronic intelligence and will be used to track missile and satellites to aid India's strategic weapons and anti-ballistic missiles. It will be jointly operated by National Technical Research Organisation (NTRO), Defence Research and Development Organisation (DRDO) and the Indian Navy. The development span of ships has remained largely secretive with little information in public domain. The ship reportedly started sea trials in early 2019, and entered service in October 2020 without a public commissioning ceremony.
