Why in News?

Recently, the Indian Navy's two aircraft carriers, INS Vikramaditya and INS Vikrant, demonstrated "twin carrier operations," featuring simultaneous take-offs of MiG-29K fighter jets from both carriers, followed by cross-deck landings, underscoring a capability possessed by only a select few nations.

What are the Key Features of Indian Aircraft Carriers?

• India boasts two operational aircraft carriers, each with a rich history and unique capabilities.
• Origin:
  • INS Vikrant is the first domestically built aircraft carrier boasting 76% indigenous content. It was constructed at Cochin Shipyard Limited, it's a symbol of India's growing shipbuilding prowess.
  • On the other hand,INS Vikramaditya is a modified Kiev-class carrier, originally built for the Soviet Navy. After extensive refitting and modernisation, it was inducted into the Indian Navy in 2013.
• Size and Speed:
  • INS Vikrant weighs around 43,000 tonnes and 262 meters long. Its design prioritises manoeuvrability with a top speed of 28 knots.
  • Whereas, INS Vikramaditya is slightly larger,weighs around 44,500 tonnes and a length of 284 meters. It can reach speeds of up to 30 knots.
• Firepower and Flexibility:
  • Both carry a similar arsenal of aircraft, including MiG-29K fighter jets for air defense and ground attack, Kamov-31 helicopters for airborne early warning, MH-60R helicopters for multi-role operations, and indigenously built Advanced Light Helicopters (ALH) for utility tasks.
• Modernity and Innovation:
  • INS Vikrant incorporates the latest advancements in design, sensors, and electronics. It boasts a new combat management system, potentially offering superior situational awareness and operational efficiency.
  • INS Vikrant ensures precision operations even in adverse conditions by utilising the STOBAR (Short Take-Off but Arrested Recovery) method.
  • Whereas modernised, INS Vikramaditya still uses older technology.
• India’s Future Plans:
  • India is planning to have four aircraft carrier battle groups (CBGs) instead of three to strengthen its naval presence.
  • The Indian Navy's 15-year plan includes four fleet carriers and two light fleet carriers.
  • The new indigenous aircraft carrier INS Vishal, also known as Indigenous Aircraft Carrier 3 (IAC-3), will be built at the Cochin Shipyard, similar to INS Vikrant.

What are the Challenges Associated with Indigenisation of Aircraft Carriers?

• Technological Complexity:
  • Building an aircraft carrier involves integrating numerous advanced technologies from propulsion systems to combat management and aviation facilities.
    • India initially planned for a catapult launch system (CATOBAR) but later switched to a ski-jump launch with arrested recovery (STOBAR) due to technological limitations. While STOBAR is a proven system, it limits the operational capabilities of heavier, more advanced aircraft.
• Time-Consuming Process and High Cost Burden:
  • Designing, procuring materials, and constructing a complex warship like an aircraft carrier is a time-consuming process. Delays can impact overall costs and strategic planning.
    • The design work for INS Vikrant began in 1999, but the carrier wasn't commissioned until 2023 – a delay of over two decades.
    • This extended timeline can also lead to technological advancements rendering some aspects of the carrier obsolete even before its completion.
  • Building an aircraft carrier is an expensive undertaking, requiring significant investment in materials, labour, and specialised technologies.
• Skilled Manpower and Industrial Base:
  • Constructing an aircraft carrier necessitates a large pool of skilled workers with expertise in various disciplines.
    • India had to rely on foreign expertise and technology transfer for certain aspects of INS Vikrant's construction, highlighting the need for further development of its domestic shipbuilding industry.
• Material Dependence:
  • Even with an indigenous design, some critical materials and components might still need to be imported, creating a reliance on foreign suppliers.
    • Although INS Vikrant boasts a high percentage of indigenous content, some key elements like high-tensile steel and specialised electronics might have been sourced internationally. This can create vulnerabilities in times of geopolitical tensions.

What is the Significance of Carrier Aviation for India in Modern Strategic Terms?

• Supporting Land and Air Operations:
  • In the context of the ongoing disputes along India's land boundaries, the potential for border conflicts persists, emphasising the strategic advantage robust aircraft carriers would provide in future conflicts.
    • During the 1971 operations for the liberation of Bangladesh, INS Vikrant's aircraft played a crucial role in striking deep into East Pakistan, highlighting its strategic significance in supporting land battles.
• Maintaining Security of Sea-Lines of Communication:
  • In times of military conflict, an aircraft carrier serves as the primary naval asset capable of comprehensively protecting merchant shipping routes vital for carrying strategic commodities to India.
    • Concerns have been raised regarding the vulnerability of energy imports through the Strait of Hormuz due to China's strategic presence in Pakistan's Gwadar port, underscoring the importance of carriers in safeguarding sea-lines of communication.
• Ensuring Presence in the Indian Ocean Region (IOR):
  • India's security interests are intricately linked to the Indian Ocean and its surrounding littoral region, where the presence of Chinese strategic assets poses challenges to India's influence.
    • An aircraft carrier enables India to assert its influence in these waters and deter potential threats from extra-regional powers, thereby safeguarding its interests in the IOR.
• Protection of Important Overseas Interests:
  • Carrier aviation provides India with the capability to safeguard its strategic interests overseas, particularly in Afro-Asian states facing political, socio-economic, and ethnic instabilities.
    • India's economic and strategic stakes are increasing in these regions, necessitating the ability to respond effectively to emerging threats and protect its citizens and assets abroad.
• Securing Island Territories:
  • Integral naval aviation is essential for defending India's remote island territories, such as the Andaman and Nicobar Islands, which are vulnerable due to their geographical spread and limited infrastructure.
    • The presence of an aircraft carrier serves as a deterrent against potential foreign military occupation or claims, ensuring the security of these strategically important territories.
• Other Non-Military Missions:
  • Beyond its military role, an aircraft carrier significantly expands India's operational capabilities to respond to natural disasters in regional seas or littoral areas.
  • With its capacity akin to a floating city, a carrier can provide essential services and logistical support, complementing existing sealift platforms and enhancing India's disaster response capabilities.
  • Efforts to incorporate modular concepts further enhance the carrier's versatility for non-military missions, enabling rapid deployment of specialised resources for specific humanitarian missions.

Conclusion

India's focus on indigenous production and ambitious plans for additional carriers demonstrate its commitment to building a future-proof and powerful navy. While the debate between aircraft carriers and submarines continues, India's twin carrier operations showcase its strategic intent to leverage both for a comprehensive maritime defence strategy.
