Indigenously built light combat aircraft of India:

The indigenously built light combat aircraft of India is the Vikrant. Let's understand why it is the correct answer:

1. Introduction:
The light combat aircraft (LCA) is a fighter aircraft designed and manufactured in India. The aim of developing an indigenous aircraft was to reduce dependence on foreign countries for military equipment and to boost the domestic defense industry.

2. Development of LCA:
The development of the LCA began in the 1980s by the Aeronautical Development Agency (ADA) in collaboration with Hindustan Aeronautics Limited (HAL). The project faced several challenges, including technical difficulties, funding issues, and delays. However, after years of research and development, the first indigenously built LCA, named Tejas, was introduced.

3. Tejas - The Initial Version:
The initial version of the LCA, known as Tejas, is a single-seat, single-engine, multirole fighter aircraft. It was designed to meet the requirements of the Indian Air Force and Indian Navy. Tejas is equipped with modern avionics, advanced radar systems, and a state-of-the-art electronic warfare suite.

4. Upgraded Version - LCA Mk 1A:
To enhance the capabilities of Tejas, an upgraded version called LCA Mk 1A was developed. It incorporates advanced features such as an improved active electronically scanned array (AESA) radar, air-to-air refueling capability, updated avionics, and enhanced maintainability.

5. The Indigenous Aircraft Carrier - Vikrant:
The Vikrant is an indigenously built aircraft carrier by India. It is designed to operate various naval aircraft, including the LCA. The LCA has been modified to meet the requirements of carrier-based operations, such as reinforced landing gear, stronger airframe, and arrester hook.

6. Significance of Vikrant:
The development of the Vikrant aircraft carrier and the integration of the LCA demonstrate India's progress in building a strong defense infrastructure. It reduces the country's dependence on foreign carriers and aircraft, enhances its naval capabilities, and strengthens its indigenous defense industry.

Conclusion:
The indigenously built light combat aircraft of India is the Vikrant, which is designed to operate from the indigenous aircraft carrier of the same name. The development of indigenous military equipment like the LCA and aircraft carriers like Vikrant showcases India's commitment to self-reliance in defense production.
