## UPSC CSE Context **Why in News:** Indian Navy to commission sixth Project 17A stealth frigate Mahendragiri at Visakhapatnam. **Syllabus Connection:** Defence technology, indigenisation, maritime security, and naval modernisation under Security and Science & Technology. **Exam Relevance:** Highlights India's progress in indigenous warship building, self-reliance in defence, and implications for maritime security in the Indo-Pacific. ## Core Issue Commissioning of indigenous stealth frigate Mahendragiri boosts Navy's capability and indigenisation. **Key Development:** Mahendragiri (F38), sixth Project 17A frigate, to be commissioned with over 75% indigenous content. **Stakeholders:** - Mazagon Dock Shipbuilders Limited - Warship Design Bureau - MSMEs ## Static Knowledge **High-Value Background:** - Project 17A is a follow-on class of stealth frigates under construction since 2019, with improved stealth features and automation over Project 17 (Shivalik class). - Indigenous content includes weapons, sensors, and combat management systems, reducing dependency on foreign OEMs. **Exam Linkage:** - Useful for questions on defence indigenisation, 'Make in India' in defence, and naval modernisation. **Concepts in Context:** - Stealth frigate: warship designed with reduced radar cross-section, infrared signature, and acoustic emissions to evade detection. - Combined diesel or gas (CODOG) propulsion: uses diesel engines for cruising and gas turbines for high speed, balancing fuel efficiency and power. ## Dynamic Analysis ### Defence Indigenisation - Over 75% indigenous content demonstrates progress in self-reliance under 'Atmanirbhar Bharat' in defence. - Indigenous weapons and sensors reduce import dependency and enhance strategic autonomy. ### Maritime Security - Mahendragiri enhances Navy's capability for anti-air, anti-surface, and anti-submarine operations, critical for sea lane security. - Strengthens India's ability to project power and conduct sustained operations in the Indo-Pacific. - Capability for HADR and search and rescue aligns with India's role as a net security provider in the region. ### Technology and Innovation - Advanced stealth features and reduced radar signature improve survivability in contested environments. - Integrated combat management system enables network-centric warfare and faster decision-making. - High degree of automation reduces crew fatigue and improves operational efficiency. ## Prelims Takeaways - Project 17A frigates are stealth warships built by MDL and GRSE for Indian Navy. - Mahendragiri is named after a mountain range in Eastern Ghats. ## Mains Value Addition **Arguments:** - Indigenous warship building reduces strategic vulnerabilities and supports defence export potential. - Project 17A showcases successful collaboration between Navy design bureau and public sector shipyards. - High indigenous content in complex platforms like frigates demonstrates maturation of Indian defence industrial base. **Examples:** - Mahendragiri (F38) is the sixth ship of Project 17A, following Nilgiri, Himgiri, Udaygiri, Dunagiri, and Taragiri. **Data Points:** - Over 75% indigenous content in Mahendragiri. **Counterpoints:** - Despite high indigenisation, some critical components like gas turbines may still be imported. - Delays in Project 17A construction have affected Navy's force levels. ## Way Forward - Accelerate delivery of remaining Project 17A ships to meet Navy's operational requirements. - Promote indigenous design and production of gas turbines and other critical systems to achieve full self-reliance. - Leverage MSME network to create a robust defence supply chain and reduce lead times. - Explore export potential of Project 17A frigates to friendly foreign navies.
