What Happened
- The first batch of Tejas MK 1A fighter jets — originally scheduled for delivery to the Indian Air Force (IAF) in March 2024 — is now expected to be inducted latest by June–July 2026, a delay of over two years.
- HAL (Hindustan Aeronautics Limited) has completed weapons trials and certified five aircraft as meeting major contracted capabilities of the Air Staff Qualitative Requirements (ASQR).
- The primary delay factor has been engine supply: American firm GE Aerospace has delivered only five F404-IN20 engines against a 2021 contract for 99 engines (30 were due by early 2024).
- A second bottleneck has emerged in software and avionics integration — specifically the Israeli-origin ELTA EL/M-2052 AESA radar, which is experiencing integration issues with the aircraft's Electronic Warfare (EW) suite.
- Nine additional aircraft have completed their first flights and await engine deliveries; HAL aims to deliver 12 aircraft in financial year 2025–26.
- The IAF and Ministry of Defence have agreed to some exemptions on full ASQR compliance, but will not compromise on "must-have" capabilities.

LCA Tejas Programme: India's Indigenous Fighter Jet
The Light Combat Aircraft (LCA) programme was initiated in 1984 under the Aeronautical Development Agency (ADA) within DRDO, with HAL as the prime industrial contractor. The Tejas MK 1A is a 4.5-generation variant of the original LCA, upgraded with an Active Electronically Scanned Array (AESA) radar, Beyond Visual Range (BVR) missiles, an advanced Electronic Warfare suite, and Air-to-Air Refuelling capability. The contract for 83 aircraft (73 MK 1A fighters + 10 MK 1 trainers) was signed in February 2021 for approximately ₹48,000 crore — the largest indigenous defence contract at the time.
- Aircraft classification: 4.5-generation Light Combat Aircraft (single-engine)
- Programme lead: ADA (DRDO); manufacturer: HAL, Nashik/Bangalore facilities
- Contract: 83 aircraft signed February 2021 for ₹48,000 crore (~USD 6.5 billion)
- Engine: GE F404-IN20 (American; 98 kN thrust with afterburner)
- AESA Radar: ELTA EL/M-2052 (Israeli, licence-manufactured in India by BEL)
- Key capabilities: BVR missiles (Derby, Astra), AAR probe, self-protection jammer
- Original delivery schedule: First aircraft by March 2024; full 83 by February 2028
Connection to this news: The Tejas MK 1A delay directly impacts IAF's squadron strength — the force operates at 31 squadrons against a sanctioned strength of 42, and Tejas was expected to be the primary platform bridging this gap in the 2024–2030 window.
Defence Procurement Process and ASQR
India's defence procurement follows the Defence Acquisition Procedure (DAP) 2020. For indigenously developed platforms, the Air Staff Qualitative Requirements (ASQR) define the minimum operational capabilities a delivered aircraft must meet. When a vendor requests deviations, the case goes to the Defence Acquisition Council (DAC) chaired by the Defence Minister. The ongoing HAL–IAF negotiation on ASQR waivers for Tejas MK 1A reflects the inherent tension in DAP between pushing indigenous platforms to market quickly and ensuring they meet operational readiness standards.
- DAP 2020: Governs all defence procurement; successor to DPP 2016
- DAC: Apex procurement authority; chaired by Defence Minister
- ASQR: Air-specific qualitative requirements; sets minimum capability benchmarks
- Buy (Indian-IDDM): Highest indigenisation category; Tejas qualifies under this
- iDEX (Innovations for Defence Excellence): Supports startups but not applicable here
- HAL's ASQR waiver request: Disputed between HAL and IAF on radar/EW integration
Connection to this news: The MoD–IAF agreement to accept some ASQR exemptions while holding firm on "must-have" capabilities is a critical procurement decision — it sets a precedent for how India balances indigenisation timelines with operational readiness in future platforms (AMCA, TEDBF).
India's Indigenous Defence R&D Ecosystem
The Tejas programme is the centrepiece of India's long-term vision for self-reliance in fighter aviation. DRDO's ADA leads design; HAL manufactures; BEL produces subsystems like the AESA radar. The programme also involves ISRO (carbon fibre composites), CSIR-NAL (materials), and private sector firms. Despite delays, it has generated over 500 components developed indigenously. The successor platforms — AMCA (Advanced Medium Combat Aircraft, twin-engine stealth, 5th generation) and TEDBF (Twin Engine Deck Based Fighter for the Navy) — are in design phases.
- ADA (Aeronautical Development Agency): Under DRDO; leads LCA design
- HAL facilities: Aircraft Division, Bangalore (final assembly); Nashik (production)
- BEL (Bharat Electronics Ltd): Produces AESA radar subsystems under licence
- AMCA: 5th-generation stealth fighter; in detailed design phase (target: first flight 2028–29)
- TEDBF: Naval variant for INS Vikrant; design phase
- Indigenisation content: ~60% for MK 1A; target >80% for AMCA
Connection to this news: The Tejas MK 1A delays highlight the structural vulnerabilities of India's indigenous defence ecosystem — dependence on foreign engines (GE) and foreign radar technology (ELTA) — even as the platform is marketed as a Make in India success story.
