LCA Tejas gets Final Operational Clearance

The Indian Air Force (IAF) has received the Final Operational Clearance (FOC) standard certification for Light Combat Aircraft (LCA) Tejas from Defence Research and Development Organisation (DRDO). The DRDO’s FOC certification testifies the combat-readiness of Tejas.

The Centre for Military Airworthiness and Certification (CEMILAC) is a DRDO laboratory authorised to certify military aircraft and airborne systems. To get the final operational clearance, the aircraft must have battle-time capabilities of mid-air refuelling, AESA radar, electronic warfare suites, a variety of bombs and weapons, among others.

LCA Tejas

LCA Tejas is lightweight single-seat multi-role jet fighter powered by a single engine. It has tailless and compound delta wing design made entirely of composite structures. It is pegged as the world’s smallest and lightest supersonic fighter aircraft in its class.

LCA Tejas is first advanced fly-by-wire Light Combat Aircraft (LCA) designed, developed and manufactured indigenously by state-owned Hindustan Aeronautical Limited (HAL) and Aeronautical Development Agency (ADA) as part of LCA programme, started in the 1980s to replace India’s ageing MiG-21 fighters. It was named ‘Tejas’, which means ‘radiance’, by former prime minister Atal Bihari Vajpayee.

Advance Features

LCA Tejas is equipped with the quadruplex digital fly-by-wire flight control system to ease handling by the pilot. It also has a digital computer-based attack system and autopilot mode. It is also equipped with the satellite-aided Inertial Navigation System.

Stealth Features

It has many features of stealth fighter aircraft. Its radar cross section is very less compared to other aircrafts like MiG-29, F-16 due to its small size and extensive usage of carbon composites.  It incorporates a glass cockpit in which the pilot is fed with real-time information. It also has open architecture software for avionics which can be easily updated as and when required.

Range

It has a limited reach of little over 400-km and will be mainly used for close air-to-ground operations (unlike Russian-origin Sukhoi-30MKIs or Rafale which have deep strike capability into enemy territory due to their long range).

Weaponry

It can fire air-to-air missiles, carry bombs and precision guided ammunition. DRDO has successfully tested fired Tejas with different kinds of weaponry and missiles including R-73 air-to-air missile, bomb dropping (including laser-guided bombs). DRDO also plans test firing of indigenous Astra missile from the Tejas.

Operations

LCA Tejas had commenced operations from Sulur Air Force Station in Tamil Nadu in July 2018, two years after it was formally inducted into IAF. The fighter jet is part of ‘Flying Daggers’ of 45 Squadron of IAF. Southern Air Command based in Kerala capital Thiruvananthapuram has been entrusted with the responsibility of integrating fighter aircraft in IAF’s concept of operations.

IAF successfully conducts series of flight trials of Astra Beyond Visual Range Air-to-Air Missile

Indian Air Force (IAF) has successfully undertaken series of flight trials of Astra Beyond Visual Range Air-to-Air Missile (BVR-AAM) from September 26 to October 3, 2018. The tests were conducted at Integrated Test Range (ITR), Balasore, Odisha as part of final development trials of the missile.

About test

The missile was tested in combination of complex tests for engagement of pilotless target in different modes of manoeuvring, off-boresight, medium and long ranges. These trials were combination of complex tests for engagement of pilotless target in different modes of manoeuvring, off-boresight, medium and long ranges. These tests make missile ready for induction in service in 2019.

Astra Missile

Astra is air to air beyond visual range air-to-air indigenously developed by Defence Research and Development Organisation (DRDO). More than 50 private and public sector industries are involved in development and production of different sub-systems of the missile.

It is one of the smallest weapon system developed by DRDO, having length of 3.8-metre and weighing 154kg. It is single stage solid fuelled missile and has payload capacity of 15 kg conventional explosives.

It can be launched from different altitudes and is capable of engaging targets at varying range and altitudes at both short-range targets (up to 20 km) in tail-chase mode and long-range targets (up to 80 km) in head-on mode. It is radar homing supersonic missile having maximum speed of Mach 4 (four times speed of sound). It possesses high Single Shot Kill Probability (SSKP) making it highly reliable.

It is all-weather missile with active radar terminal guidance, excellent electronic counter-counter measure (ECCM) features, smokeless propulsion and process improved effectiveness in multi-target scenario.It has advance on-board electronic counter-measures that jam radar signals from enemy radar, making tracking of the missile difficult.

It is fitted with terminal active radar-seeker and an updated mid-course internal guidance system that helps missile to locate and track targets. The missile can be integrated with all fighter aircraft of IAF including Sukhoi-30 MKI, Mirage-2000, MiG-29, Jaguar and the Tejas Light Combat Aircraft (LCA).
