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.
