Defence Indigenization
 

Defence indigenization refers to a country's efforts to develop, produce, and procure defense equipment, technologies, and systems domestically, reducing reliance on foreign imports and promoting self-reliance in defense manufacturing.

Here's an overview of defense indigenization:

  • Countries aim to reduce dependency on external sources for critical defense equipment by developing indigenous capabilities to design, develop, manufacture, and maintain defense systems and technologies
  • Indigenization in defense allows countries to maintain strategic autonomy, ensuring access to crucial defense capabilities even during times of geopolitical tensions or when facing sanctions or restrictions on imports
  • Investing in indigenous defense capabilities promotes technological advancements and innovation within the country, leading to the development of cutting-edge technologies and solutions tailored to specific national defense needs
  • Defense indigenization often has positive economic effects by creating employment opportunities, fostering a skilled workforce, and boosting local industries involved in defense manufacturing and research
  • Developing defense systems domestically can potentially reduce costs in the long term and shorten procurement timelines by minimizing bureaucratic hurdles associated with importing defense equipment
  • As countries develop their indigenous defense capabilities, it leads to the enhancement of their defense systems' quality, reliability, and customization to meet specific operational requirements

  • The policy emphasizes flexibility, transparency, and accountability in the acquisition process. It encourages greater private sector participation and a level playing field for all stakeholders
  • DAP 2020 introduces the Strategic Partnership (SP) model to promote collaboration between Indian private firms and foreign OEMs for manufacturing high-tech defense platforms like submarines, fighter jets, helicopters, and armored vehicles
Indian Air Force(IAF)
 
The Indian Air Force (IAF) is the air arm of the Indian Armed Forces. Its primary mission is to protect Indian airspace and to conduct aerial warfare during armed conflicts. The IAF was founded on October 8, 1932, and its headquarters are in New Delhi
The Indian Air Force (IAF) serves as one of the primary branches of the Indian Armed Forces responsible for aerial warfare and safeguarding the Indian airspace.
Here are key aspects of the Indian Air Force:
  • The IAF's primary mission is to secure Indian airspace and defend the country against external aggression, conducting aerial warfare, reconnaissance, and providing air support to ground forces during combat operations
  • It's organized into several operational commands, each responsible for specific geographical regions and operational roles. These commands include Western Air Command, Eastern Air Command, Southern Air Command, Central Air Command, and Southwestern Air Command
  • The IAF comprises skilled personnel trained in various specialized roles, including pilots, engineers, ground staff, and support personnel. Training facilities like the Air Force Academy and other specialized institutions ensure the professional development of its personnel
  • The IAF operates a diverse fleet of aircraft, including fighter jets like the Sukhoi Su-30MKI, Dassault Rafale, MiG-29, and Mirage 2000. It also includes transport aircraft like the C-17 Globemaster and C-130J Super Hercules, helicopters, and reconnaissance and surveillance platforms
  • The IAF continuously seeks to modernize its fleet through acquisitions and upgrades. Notably, the induction of Rafale fighter jets and ongoing acquisitions like the Tejas Light Combat Aircraft (LCA) showcase efforts to enhance operational capabilities
  • Apart from its defense role, the IAF plays a crucial role in humanitarian assistance and disaster relief (HADR) operations, providing support during natural disasters, medical evacuations, and peacekeeping missions
The importance of Air Force
 
  • Air superiority is crucial in modern warfare. The ability to control airspace provides strategic advantages, allowing for reconnaissance, aerial combat, and the ability to deny adversaries access to airspace
  • Air Forces enable nations to project power across borders and continents. They have the capability to swiftly deploy forces, conduct precision strikes, and provide support to ground and naval operations, enhancing a country's global influence
  • A strong Air Force acts as a deterrent against potential aggressors. Its capabilities can discourage adversaries from initiating conflicts or hostile actions due to the threat posed by air power
  • Airborne platforms like reconnaissance aircraft, drones, and satellites provide crucial intelligence, surveillance, and reconnaissance (ISR) capabilities, gathering information vital for strategic decision-making
  • Air Forces possess the ability to conduct precision strikes against enemy targets, including military installations, infrastructure, and communication networks, minimizing collateral damage and maximizing effectiveness
  • Air power provides critical support to ground troops by conducting close air support, airlifting personnel and supplies, and assisting in amphibious operations. It also supports naval forces by providing maritime reconnaissance and anti-submarine warfare capabilities
  • Air Forces play a vital role in providing humanitarian aid and disaster relief during natural calamities or emergencies. They can quickly deploy assets for medical evacuations, supply drops, and search-and-rescue operations
  • Air Forces often drive technological advancements, pushing boundaries in aviation, aerospace engineering, and cutting-edge technologies like stealth, unmanned systems, and hypersonic capabilities
Challenges faced by Indian Air Force (IAF)
  • The pace of admission into the air force has been sluggish. The MIG 21 has been noted for its susceptibility to accidents. The expense of producing indigenous aircraft has proven to be high. The concern for the military, the nation, and the political leadership is managing two simultaneous fronts: the immediate threat from Pakistan in the western front and the potential long-term threat from China. Accurately assessing these threats is crucial for devising appropriate countermeasures.
  • There's a lack of cooperation between Public Sector Undertakings (PSUs) and the private sector concerning the air force. To counter Pakistan, it's imperative to achieve absolute air superiority, necessitating the preparedness of the Indian Air Force (IAF) to conduct counter-air operations and robust air defense.
  • However, the diversion of expenses for these purposes is insufficient and remains a worry. In dealing with the Chinese threat, the focus should be on missiles rather than platform-based systems like fighter aircraft, considering China's advanced technological capabilities. This requires a different force structure and the implementation of an integrated air and missile defense system.
  • In today's context, technology signifies power. Prioritizing high-tech and efficient weaponry over quantity is crucial. While quantity is essential, technology should dominate.
  • The order volume is also a cause for concern. The 2019 CAG’s Audit Report on 'Capital Acquisition in the Indian Air Force' identified various issues in the acquisition process. It highlighted discrepancies in defining the Air Staff Qualitative Requirements (ASQRs), leading to vendors' inability to fully meet these criteria. The report also pointed out low vendor response, inadequate price estimation, and severe delays in the acquisition process, attributing the delays to a convoluted and multi-level approval system
