New Delhi: In a significant boost to India’s defence indigenization efforts, Steel Authority of India Ltd. (SAIL) on Wednesday announced that it has supplied the entire requirement of special grade steel for INS Arnala, the first in a series of anti-submarine warfare shallow water crafts (ASW-SWC), which was inducted into the Indian Navy today.
INS Arnala is equipped to perform subsurface surveillance, search and rescue operations, and low-intensity maritime tasks, marking a new chapter in India’s coastal defence capabilities.
