INS Mahendragiri: Project 17A's 6th Indigenous Stealth Frigate Added to Indian Navy

INS Mahendragiri (F38) is the sixth indigenously developed stealth frigate built under Project 17A (Nilgiri-Class) for the Indian Navy. Its induction marks a significant boost for India's self-reliance in defense manufacturing (Aatmanirbhar Bharat), Indo-Pacific strategic posture, and maritime security. This topic is highly relevant for UPSC, MPPSC, SSC, CDS, and other competitive examinations.

INS Mahendragiri is the sixth stealth frigate of the Nilgiri-class. It was designed by the Indian Navy's in-house Warship Design Bureau (WDB) and constructed by Mazagon Dock Shipbuilders Limited (MDL) in Mumbai. Named after the Mahendragiri mountain peak in the Eastern Ghats of Odisha, it is the first warship in the Indian Navy to bear this name.
