A Journey Towards Self-Reliance and Global Presence
The Tejas Light Combat Aircraft (LCA) is more than just a fighter jet; it’s a powerful symbol of India’s unwavering commitment to indigenous defense capabilities. From its ambitious inception to its advanced variants, the Tejas has navigated a challenging yet ultimately triumphant journey, solidifying its place as a cornerstone of the Indian Air Force (IAF) and eyeing a significant role on the global stage. This deep dive explores the remarkable evolution of the Tejas, its current prowess, and the exciting future that lies ahead.
The Genesis of Indian Air Power: Tejas Mk1’s Decades-Long Journey
The story of the Tejas began in 1983 when the Indian government initiated the Light Combat Aircraft (LCA) program. The primary objective was clear: develop an indigenous replacement for the IAF’s aging MiG-21 fleet, thereby reducing reliance on foreign suppliers. The Aeronautical Development Agency (ADA) was established in 1984 to spearhead the project, with Hindustan Aeronautics Limited (HAL) taking the lead as the production agency. After years of meticulous design and development, the first technology demonstrator, TD-1, proudly took to the skies on January 4, 2001, marking a monumental step for Indian aviation. In 2003, the aircraft was officially christened ‘Tejas,’ a Sanskrit word meaning ‘Radiant,’ embodying the nation’s aspirations.
The Tejas Mk1, a single-engine, 4.5-generation, delta-wing, multirole combat aircraft, achieved Initial Operational Clearance (IOC) in 2013, paving the way for its limited induction into the IAF. By July 2016, the first two Tejas Mk1 aircraft were delivered, leading to the formation of the No. 45 Squadron “Flying Daggers.” A significant milestone was reached in February 2019 when the Mk1 variant received its Final Operational Clearance (FOC), confirming its readiness for full combat operations. As of July 2025, the IAF operates two robust Tejas Mark 1 squadrons, with a naval variant also demonstrating its capabilities on the INS Vikramaditya aircraft carrier in January 2020. This foundational variant set the stage for more advanced iterations.

Elevating Capabilities: The Tejas Mk1A – A Leap in Indigenous Technology
Building upon the success of the Mk1, the Tejas Mk1A variant represents a significant technological upgrade, incorporating over 40 improvements to meet contemporary air combat requirements. Key enhancements include advanced avionics, a state-of-the-art Active Electronically Scanned Array (AESA) radar (the EL/M-2052 and the indigenous Uttam AESA Radar), an updated electronic warfare suite, and seamless integration of smart munitions. The indigenous content of the Tejas Mk1A is projected to exceed an impressive 70%, underscoring India’s growing self-reliance in defense manufacturing.
The development of the Mk1A has seen rapid progress. The first prototype completed its maiden flight on May 20, 2022, followed by the inaugural flight of the first production series Mk1A aircraft on March 28, 2024. Significantly, the first Tejas-Mk1A fighter produced at HAL’s Nashik facility also completed its maiden flight on October 17, 2024, highlighting the expansion of production capabilities. The Indian Air Force has placed a substantial order for 83 Tejas Mk1A aircraft, valued at ₹46,000 crore, with deliveries expected to begin in 2027-2028. An additional order for 97 Mk1A fighters was approved in August 2025, bringing the total commitment to a remarkable 180 aircraft.

To meet these ambitious delivery schedules, HAL is aggressively ramping up its production capacity. In addition to two operational lines in Bengaluru, a third production line was inaugurated at HAL’s Nashik facility in April 2023. This expansion boosts HAL’s annual production from 16 to 24 aircraft. Furthermore, a parallel private-sector supply chain involving companies like VEM Technologies, Alpha Tocol Engineering Services, and Larsen & Toubro is being leveraged to support an additional six aircraft annually, targeting a total annual output of 30 fighters by 2026-2027.
Navigating Hurdles: Challenges and Future Integration for Mk1A
Despite the significant strides, the Tejas Mk1A program faces certain challenges, particularly in weapon integration. Delays have been noted in incorporating India’s indigenous Astra Mk1 beyond-visual-range air-to-air missile due to software compatibility issues with the Israeli-supplied ELTA EL/M-2052 AESA radar. The proprietary nature of the radar’s core software and firmware requires approval from Israel Aerospace Industries (IAI) for full integration, potentially pushing the aircraft’s Full Operational Clearance (FOC) beyond its original December 2025 target. Additionally, supply chain issues have impacted the timely delivery of General Electric F404-IN20 engines, which were contracted in August 2021. HAL is actively working to overcome these hurdles, collaborating with international partners and streamlining its supply chain to ensure the seamless induction of the Mk1A into the IAF.
The Next Frontier: Tejas Mk2 – India’s Medium Weight Fighter Ambition
Looking further into the future, the Tejas Mk2, also known as the Medium Weight Fighter (MWF), represents the next evolutionary leap. This 4.5-generation, single-engine, multirole combat aircraft is designed to progressively replace legacy IAF platforms such as the SEPECAT Jaguar, Dassault Mirage 2000, and Mikoyan MiG-29, ushering in a new era of air superiority. The Mk2 will feature an elongated airframe, close-coupled canards for enhanced aerodynamic performance, new sensors, and a more powerful General Electric F414-INS6 engine, delivering 98kN thrust compared to the Mk1A’s 84kN.
The advancements in the Mk2 are substantial. It will boast an increased payload capacity of 6.5 tons across 11 weapon stations, a significant improvement over the Mk1A’s 3.5 tons on 7 hardpoints, and an extended combat radius of 1,000 km. The cockpit will be redesigned with a wide-area display, and a more advanced electronic warfare suite will further bolster its capabilities. The indigenous content for the Mk2 is planned to reach 82% initially, with aspirations to exceed 90% after the licensed production of its engine. The first Tejas Mk2 prototype roll-out is planned for late 2025, with its maiden flight anticipated in the first quarter of 2026. Four prototypes are scheduled to be built by 2027, aiming for final operational clearance by 2028 and induction by 2028-2029. Mass production is slated for 2029, with deliveries to the IAF expected from 2032 onward. Upon full induction, the IAF plans to operate at least 324 Tejas aircraft across all variants, forming 18 squadrons and significantly strengthening its operational capacity. Parallel efforts are also underway to develop the indigenous Kaveri 2.0 engine, targeting 80+ kN thrust, to further reduce reliance on imported propulsion systems.

Global Ambitions: Tejas on the World Stage and India’s Strategic Vision
The Tejas aircraft is not only transforming India’s domestic defense capabilities but also emerging as a strong contender in the international defense market. HAL is currently in advanced discussions with six countries for the export of the LCA Tejas, with talks particularly intensifying with Argentina, the Philippines, and Nigeria. Countries like Botswana and Egypt have also expressed significant interest, with Egypt considering purchasing around 20 Tejas jets and potentially establishing a local Maintenance, Repair and Overhaul (MRO) facility. Argentina is in advanced stages of negotiation for at least 15 Tejas Mk1A aircraft, with future orders for Mk2 jets also under consideration. Other nations, including Vietnam, Indonesia, Australia, and the United States, have shown interest in the platform.
The Tejas presents a compelling export opportunity due to its competitive pricing, advanced 4.5-generation capabilities, and India’s readiness to offer technology transfer and collaborative development, distinguishing it from established global players. This aligns with India’s broader strategic vision to achieve $5 billion in annual defense export revenue by 2025, a goal significantly supported by the Tejas program. Success in this arena hinges on continued boosts in indigenous component production and the provision of superior after-sales support. India’s defense exports have already reached an all-time high of ₹15,920 crore in FY2023, reflecting a growing global demand for Indian defense products.

Beyond the Tejas, this program is providing crucial momentum for India to cultivate a long-term, self-sustaining manufacturing ecosystem for advanced fighter aircraft. This includes ambitious plans for the indigenous development of the Advanced Medium Combat Aircraft (AMCA), a fifth-generation fighter, with deliveries expected to begin in 2036, and the Naval variant of Tejas (TEDBF) slated for deliveries from 2038.
