Project 17A represents a significant leap from the Shivalik-class (Project 17) frigates. These ships are built using "Integrated Modular Construction," a technique where large hull blocks are pre-assembled and then integrated, significantly reducing construction time.
Cutting-Edge Features
The Nilgiri-class is designed with a high level of indigenous content and specialized air-defense modules.
- Reduced Signature: Better deck-lines and X-form structure to ensure minimal radar echo.
- Barak-8 & BrahMos: The dual punch of Indo-Israeli Barak-8 SAM and supersonic BrahMos cruise missiles.
- Indigenous Integrated Combat System: A sophisticated command-and-control brain developed for Indian Navy requirements.
Seven Hulls, Two Yards
To accelerate production, the Indian Navy split the contract between Mazagon Dock Shipbuilders Limited (MDL) and Garden Reach Shipbuilders & Engineers (GRSE).
MDL Ships
Nilgiri, Himgiri, Taragiri, Udaygiri
GRSE Ships
Dunagiri, Vindhyagiri, Mahendragiri
Combat Management System (CMS)
The Project 17A frigates feature an advanced CMS-17A, which integrates all sensors and weapon systems on board, providing a real-time battle-space awareness. The ships also host a large flight deck to carry two multi-role helicopters (MH-60R or Sea King).
