Q. How many of the following ships are part of the seven planned vessels under Project 17A?

1. INS Taragiri
2. INS Dunagiri
3. INS Mormugao
4. INS Vindhyagiri

Select the correct answer from the codes giveb below:
Answer: Only three
Notes: The correct answer is [C] Only three. Project 17A (Nilgiri-class) consists of seven advanced stealth frigates. To solve this, we must distinguish between the Nilgiri-class frigates and the Visakhapatnam-class destroyers.

• INS Taragiri (Included): Named after a hill range in Garhwal, it is the fifth ship of Project 17A, launched at Mazagon Dock Shipbuilders (MDL).
• INS Dunagiri (Included): Named after a mountain range in Uttarakhand, it is the fourth ship of the project, launched at Garden Reach Shipbuilders & Engineers (GRSE).
• INS Vindhyagiri (Included): Named after the mountain range in Karnataka, it is the sixth ship of the class, launched at GRSE in 2023.
• INS Mormugao (Excluded): While it is a modern Indian warship, it belongs to Project 15B (Visakhapatnam-class stealth guided-missile destroyers), not the Project 17A frigate class.

The seven ships under Project 17A are: Nilgiri, Himgiri, Udaygiri, Dunagiri, Taragiri, Vindhyagiri, and Mahendragiri. These vessels are "follow-ons" to the Shivalik-class (Project 17) and feature improved stealth, advanced weapons like BrahMos, and high-tech sensors.
