INS Mahendragiri Commissioned, Strengthening Indian Navy's Stealth Frigate Fleet

Detailed Summary

The Indian Navy commissioned INS Mahendragiri, marking a significant addition to its stealth frigate fleet under Project 17A (Nilgiri-class), which follows the earlier Shivalik-class (Project 17) frigates. Named after a mountain peak in Odisha, the warship is built indigenously, reflecting India's push toward self-reliance in defence manufacturing under the 'Atmanirbhar Bharat' initiative. Project 17A frigates feature improved stealth features, advanced weapons and sensor packages, and enhanced survivability compared to their predecessors.

Historical Background

India's warship-building programme has evolved through successive frigate classes - Godavari (Project 16), Brahmaputra (Project 16A), Shivalik (Project 17), and now Nilgiri (Project 17A) - each generation incorporating improved stealth and indigenous content.
