The Indian Navy recently received INS Udaygiri, the second stealth frigate of Project 17A, delivered in a record time of 37 months, strengthening India’s naval capabilities.

About Stealth Frigate

A stealth frigate is a modern naval warship designed to evade enemy detection by minimizing various signatures.

• Radar Cross-Section Reduction: Stealth frigates have specially designed hulls and superstructures that deflect and absorb radar waves, reducing their radar visibility.
• Signature Management: These ships use advanced technologies to manage electromagnetic emissions, minimizing detection by enemy electronic sensors.Low Infrared and Acoustic Signatures: Stealth frigates employ thermal masking materials and sound-reducing designs to lower infrared and acoustic footprints, making them harder to detect by heat-seeking and sonar systems.
• Multi-role Capability: Stealth frigates are equipped for anti-submarine, anti-air, maritime patrol, and escort missions, offering strategic flexibility in modern naval warfare.

About Udaygiri Frigate

• Udaygiri is the modern avatar of the erstwhile INS Udaygiri (a steam-powered ship decommissioned in 2007). 

Key Features

• Enhanced Stealth: Superior radar, thermal, and acoustic signature reduction.
• State-of-the-Art Systems: Fitted with advanced weapons, sensors, and modern warfare technologies.
• Multi-Mission Capability: Can counter both conventional and non-conventional threats across maritime domains.

Significance of Udaygiri

• Boost to Maritime Security: Enhances India’s blue-water naval operations and maritime dominance.
• Symbol of Atmanirbhar Bharat: Demonstrates India’s growing indigenous capabilities in advanced naval ship design and construction.
• Engineering Excellence: Reflects the progress of Indian shipyards in delivering complex warships within stringent timelines.
• Strategic Value: Adds significant strength to the Indian Navy’s surface fleet in an increasingly contested Indo-Pacific region.
• Industrial Collaboration: Supported by over 200 Indian MSMEs, reflecting the strength of India’s defence industrial base.
