The Indian Navy's INSV Kaundinya received a water salute on Wednesday as it completed its voyage from Gujarat's Porbandar to Oman's Muscat after 18 days at sea. Unlike modern naval ships, INSV Kaundinya has no engine or propulsion system and relies on wind, sails and shipbuilding methods. Its design is based on a fifth-century ship depicted in Ajanta Caves paintings.
