Which one of the following is the best description of 'INS Astradharini', that was in the news recently?

INS Astradharini is India's first indigenously built Torpedo Launch and Recovery Vessel (TLRV), commissioned to conduct technical trials and recovery of underwater weapons like torpedoes and mines. While it might be mistaken for an amphibious warfare ship due to the frequent news coverage of such vessels, its unique catamaran hull design is specifically optimized for weapon testing rather than troop transport. The core concept tested is the identification of specialized indigenous defense platforms and their specific functional roles within the Indian Navy.
