Introduction to INS Vikrant: India’s Pride in Indigenous Naval Technology
The commissioning of INS Vikrant, India’s first indigenously designed and built aircraft carrier, on September 2, 2022, marked a historic milestone in the nation’s journey toward self-reliance in defense manufacturing. Named after the iconic INS Vikrant that served during the 1971 Indo-Pak War, this modern marvel embodies the spirit of Aatmanirbhar Bharat (Self-Reliant India). For students preparing for competitive exams like UPSC, CDS, NDA, or other defense-related tests, understanding INS Vikrant’s indigenous technology is crucial, as it frequently appears in questions related to defense, technology, and India’s maritime strategy.
The Genesis of INS Vikrant: A Vision for Self-Reliance
The idea for an indigenous aircraft carrier took shape in the late 1980s, with formal design work beginning in 1999 under the Indian Navy’s Directorate of Naval Design (DND). The keel-laying ceremony at Cochin Shipyard Limited (CSL) in 2009 marked the start of a challenging yet transformative journey. Despite delays due to technological complexities and the COVID-19 pandemic, INS Vikrant’s completion showcases India’s growing expertise in warship design and construction.
INS Vikrant, also known as Indigenous Aircraft Carrier-1 (IAC-1), is a testament to India’s ability to join an elite group of nations—USA, UK, France, Russia, and China—capable of building aircraft carriers indigenously. With over 76% indigenous content, the project has spurred the development of ancillary industries, creating over 2,000 direct jobs at CSL and 12,000 indirect jobs across the country.
Key Milestones in INS Vikrant’s Development
- 1999: Project greenlit by then-Defence Minister George Fernandes.
- 2009: Keel-laying ceremony at Cochin Shipyard Limited.
- 2013: Launch and naming ceremony as INS Vikrant.
- 2020: Basin trials to test propulsion and power systems.
- 2021: Maiden sea trials to evaluate hull and auxiliary equipment.
- 2022: Commissioned by Prime Minister Narendra Modi on September 2.
For exam aspirants, memorizing these milestones can help answer questions on India’s defense modernization and shipbuilding capabilities.
Indigenous Technologies Powering INS Vikrant
INS Vikrant’s indigenous technology is a blend of advanced engineering, innovative materials, and cutting-edge systems. Below, we explore the key technological components that make this aircraft carrier a symbol of India’s self-reliance.
1. Warship-Grade Steel: DMR 249A and 249B
One of the standout achievements of INS Vikrant is the use of indigenous warship-grade steel, developed by the Steel Authority of India Limited (SAIL) in collaboration with the Indian Navy and the Defence Metallurgical Research Laboratory (DMRL). Approximately 30,000 tonnes of DMR 249A (for hull and interiors) and DMR 249B (for the flight deck) were supplied by SAIL’s plants in Bhilai, Bokaro, and Rourkela. This import-substitute steel underscores India’s ability to produce high-strength materials for defense applications.
Exam Tip: Questions on indigenous defense materials often highlight SAIL’s role. Note that DMR 249A and 249B are now used in all Indian warships, enhancing export potential.
2. Propulsion and Power Systems
INS Vikrant is powered by four General Electric LM2500+ gas turbines, generating over 80 megawatts of power across two shafts. While the turbines are imported, the gearboxes, designed and supplied by Elecon Engineering, are indigenous. The ship’s propulsion system enables a maximum speed of 28 knots (52 km/h) and an endurance of 7,500 nautical miles (13,800 km).
The high degree of automation in machinery operation, navigation, and survivability systems reduces crew requirements and enhances operational efficiency. This automation is a product of indigenous software and control systems developed by Indian engineers.
3. Aircraft Operations: STOBAR Configuration
INS Vikrant employs a Short Take-Off But Arrested Recovery (STOBAR) system, featuring a ski-jump for launching aircraft and arrester wires for recovery. The 12,500-square-meter flight deck can operate 12 fighter jets and 6 helicopters simultaneously, accommodating up to 30 aircraft, including:
- MiG-29K fighters (Russian-origin).
- Kamov-31 airborne early-warning helicopters.
- Indigenous Advanced Light Helicopters (ALH Dhruv).
- US-manufactured MH-60R multi-role helicopters.
The planned integration of Rafale-M jets, approved in a ₹64,000-crore deal with France in 2025, will further enhance Vikrant’s strike capabilities.
Exam Tip: Understand the STOBAR system and aircraft types for questions on naval aviation and defense procurement.
4. Defense Systems
INS Vikrant is equipped with robust indigenous defense systems, including:
- Barak 8 Surface-to-Air Missiles: A 32-cell Vertical Launch System (VLS) for long-range air defense, developed jointly by India and Israel.
- Otobreda 76mm Cannons: Four dual-purpose cannons for anti-aircraft and anti-surface roles.
- AK-630 Close-In Weapon Systems (CIWS): Four rapid-fire systems for close-range defense against missiles and aircraft.
These systems highlight India’s progress in integrating indigenous and collaborative technologies for comprehensive warship protection.
5. Design and Automation
Designed by the Indian Navy’s Warship Design Bureau, INS Vikrant incorporates over 2,300 compartments across 14 decks, including five in the superstructure. The ship features specialized cabins for women officers, reflecting gender inclusivity. Its advanced automation systems, developed by Indian firms, ensure efficient navigation, machinery operation, and survivability.
Exam Tip: Questions on INS Vikrant’s design often focus on the Warship Design Bureau and the ship’s crew capacity (1,645 personnel, including 196 officers).
Strategic Significance of INS Vikrant
INS Vikrant’s induction has bolstered India’s maritime security and power projection in the Indian Ocean Region (IOR), a critical area amid China’s expanding naval presence. The carrier enhances the Indian Navy’s ability to conduct diverse operations, including anti-submarine warfare, humanitarian assistance, and precision airstrikes.
1. Maritime Dominance
With a displacement of 45,000 tonnes, INS Vikrant complements INS Vikramaditya, the Navy’s Russian-origin carrier. Together, they ensure India’s ability to maintain a carrier battle group (CBG) on both the eastern and western seaboards. Naval commanders advocate for a third carrier, tentatively named INS Vishal, to ensure continuous operational readiness.
2. Regional Stability
INS Vikrant’s presence strengthens India’s role in maintaining a rules-based maritime order in the Indo-Pacific, aligning with initiatives like the Quad. Joint exercises like Varuna with France in March 2025 demonstrate Vikrant’s interoperability with allied navies.
3. Economic and Soft Power
The project has catalyzed India’s defense ecosystem, involving over 500 businesses and fostering innovation in shipbuilding and ancillary industries. The carrier’s commissioning has garnered international acclaim, enhancing India’s soft power and defense trade ties with nations like the UK, USA, and France.
Exam Tip: For mains questions, discuss INS Vikrant’s role in Aatmanirbhar Bharat, its economic impact, and its strategic importance in the IOR.
Challenges in Indigenous Defense Technology
Despite its success, INS Vikrant’s development faced challenges that highlight gaps in India’s defense ecosystem:
- Imported Components: Nearly 70% of the “fight” (weapons) and “move” (propulsion) components, including gas turbines, are imported.
- Technological Gaps: Critical technologies like advanced radars and manufacturing processes require further development.
- Time Overruns: The project took nearly two decades due to delays in design, procurement, and testing.
To address these, experts recommend enhancing underwater domain awareness using AI/ML, fostering public-private partnerships, and investing in MSMEs for defense innovation.
Exam Tip: Be prepared for questions comparing India’s indigenous defense capabilities with global leaders like China or the USA.
