Comments: Contrary to other published reports, these ships were not built at Hindustan Shipyards, Vizag. These are Type B-561 cargo-passenger vessels designed & built by Szczecin Shipyard in Szczecin, Poland. They were originally ordered by the Ministry of Transport & Navigation for service with the Shipping Corporation of India Ltd (SCI) and were later acquired by the Indian Navy for troop transport duties. The design of the Type B-561 was however sold to India for license construction. The ships have large davits for LCVPs (Landing Craft, Vehicle, Personnel) and feature a high bridge forward, funnel aft and helicopter platform at the stern. The vessels could have a more general purpose role, other than troop transport.
