The Light Combat Aircraft (LCA) TEJAS MK-1A program has achieved a critical operational milestone with the successful completion of full weapons integration and live-firing trials of the ASTRA MK-1 Beyond Visual Range (BVR) and ASRAAM Close Combat Missiles (CCM).

This marks a major step in enhancing the indigenous fighter’s combat readiness and signals its readiness for full-scale deployment across the Indian Air Force.

Hindustan Aeronautics Limited (HAL) and the Aeronautical Development Agency (ADA) executed multiple rounds of weapon integration and launch validation trials over the past year, covering both developmental aircraft and front-line production variants.

These trials confirmed seamless avionics–weapon interface efficiency, successful target acquisition and engagement across all tactical regimes, and system stability during high-g manoeuvres.

The ASTRA MK-1 missile, developed by the Defence Research and Development Organisation (DRDO), was tested in various modes including head-on and tail-chase engagements, confirming its operational envelope from high-altitude intercepts to low-level firings.

The indigenous BVR missile, capable of engaging targets beyond 100 km, now integrates fully with TEJAS’ Open Mission Computer, radar, and electronic warfare suite.

Parallel testing of the ASRAAM, supplied through MBDA under an IAF standardisation plan, has verified its compatibility with TEJAS’ stores management system and sensor fusion architecture. The missile demonstrated high off-bore-sight engagement and robust lock-on performance using the aircraft’s Helmet Mounted Display and Sight (HMDS), strengthening its close-range combat capability.

This successful integration grants the TEJAS MK-1A India’s widest operational air-to-air missile coverage, including both forward and rear hemisphere engagements. Few light fighters globally possess such comprehensive missile integration across both BVR and Within Visual Range categories, positioning TEJAS as a front-line platform capable of confronting advanced aerial threats.

According to HAL sources, the completion of these trials clears the final operational qualification milestones required by the IAF for full induction of the ASTRA MK-1 and ASRAAM on TEJAS MK-1A squadrons. The aircraft can now carry mixed missile payloads, adapting its load-out based on mission profiles and target priorities.

The trials’ success further validates the maturity of the TEJAS avionics and fire-control system, reflecting the culmination of years of modular integration work undertaken by ADA, HAL, and key technology partners. Engineers report that no major modifications to the airframe or pylons were needed, indicating the robustness of the aircraft’s baseline architecture.

The MK-1A now progresses towards final operational clearance with fully validated weapons capability. This milestone positions the platform for accelerated induction into IAF service, complementing the indigenous push for deeper self-reliance in aerospace weapons and systems integration.

With ASTRA MK-2 already in advanced flight evaluation and Astra IR variant development underway, future TEJAS iterations are expected to carry an entirely indigenous air-to-air missile suite, reinforcing India’s strategic autonomy in aerial warfare technology.

Astra Mk-1 MissileIndigenous BVR missile with active radar homingFully integrated with radar and avionics; validated for head-on and tail-chase engagements at various altitudes and ranges
ASRAAM MissileAdvanced short-range air-to-air missile with infrared guidance and high off-boresight capabilityIntegrated with HMDS and weapons management system for close-range dogfight engagements
Weapon HardpointsNine external hardpoints on wings and fuselageSupports mixed loadouts of Astra Mk-1, ASRAAM, and other missiles or bombs; no airframe modifications needed
Fire Control SystemUpgraded digital fire control computer (DFCC Mk1A)Manages missile launch sequences, tracking, and mid-course updates
Communication SuiteVHF/UHF radios with counter-countermeasures and data linkFacilitates networked targeting data and missile data exchange for cooperative engagement
Inertial Navigation & GPSSagem SIGMA 95N ring laser gyroscope INS combined with GPSProvides precise navigation and targeting coordinates for weapon release
Pilot InterfaceHands-on-throttle-and-stick (HOTAS) systemReduces pilot workload, allowing seamless weapon selection and release

This architecture facilitates the TEJAS MK-1A’s comprehensive air-to-air missile capability, enabling both ASTRA MK-1 for long-range engagements and ASRAAM for close-in dogfighting with efficient sensor fusion and weapon control integration.

If needed, integration with other weapons like R-73, Python-5, and the French AASM Hammer precision-guided munition is accommodated within this modular avionics framework, further broadening the aircraft’s mission versatility and combat effectiveness.

This comprehensive integration ensures the TEJAS MK-1A can leverage India’s indigenous missile technology while maintaining interoperability with proven foreign missile systems for tactical flexibility and future upgrades.​
