Light Combat Aircraft - TEJAS
Made In India
TEJAS
Tejas is a lightweight multi-role jet fighter developed by India. It
is a tailless, compound delta wing design powered by a single
engine. It came from the LCA programme, which began in the
1980s to replace India's aging MiG-21 fighters
The Need
Indian Aerospace Self Reliance
TEJAS
It is the smallest lightweight, multi-role, single-engine
tactical fighter aircraft in the world and is being developed
in single-seat fighter and twin seat trainer variants for the
Indian Air Force and Indian Navy.

Weapons
The Tejas is designed to carry a veritable plethora of air to air, air to surface,
precision guided and standoff weaponry. In the air to air arena, the Tejas
carries long range beyond visual range weapons, with highly agile high off-
boresight missiles to tackle any close combat threat. A wide variety of air to
ground munitions and an extremely accurate navigation and attack system
allow it to prosecute surface targets over land or at sea with unparalleled
accuracy, giving the Tejas true multi/swing role capability.
The Makers
• Also many Indian Public &
private sector industries
and academic institutions.
Phases
Phase 1 - TECHNOLOGY DEMONSTRATION STAGE (TD-1 & 2)
The focus in this phase was on ‘proof of concept’. It entailed the development and testing of two
technology demonstrator aircraft. These aircraft were called TD-1 and TD-2. The decision to move
forward was to be taken after the successful completion of this phase. This would be followed by the
production of additional prototype vehicles. There were teething issues during this phase and finally TD-
1 flew on 04 January 2001 with Wing Commander Rajiv Kothiyal on the controls. The significance of this
golden-day in the history of Indian aviation can be gauged by the fact that the last time an indigenous
aircraft had got airborne was almost 40 years ago on 17 June 1961.
Phase 2 - ADDITIONAL TESTING PHASE (PV-1, PV-2, PV-3 and PV-5)
This phase consisted of additional testing and development of systems using
Prototype Vehicles which would lead to the development of the final variant that
would join the IAF and the Indian Navy. The first Prototype Vehicle, PV-1 flew on 25
November 2003.
By 2005, the Tejas had proven itself in the testing phase and the first order for 20
Series Production aircrafts was placed. A follow on order for an additional 20 SP
aircraft was placed in 2010.

Timeline
THE FIRST FLIGHT – The First Man!
2001 - The Tejas first flight took place on 04 January 2001 with Wg. Cdr. Rajiv Kothiyal
on the controls. It was a red-letter day in the history of Indian aviation. On 4th Jan was
the historic first flight of the Technology Demonstrator TD-1 marking a new era in the
aviation history of India.
2002 - 6th June - TD-2 made her successful maiden flight.
2003 - Prime minister Atal Bihari Vajpayee named LCA – "Tejas" meaning Radiance in
ancient Indian language Sanskrit.
Tejas crossed the sonic barrier for the first time
25th November - PV-1 made her successful maiden flight
Timeline
LCA was renamed to ‘Tejas’ in the presence of Prime
Minister A.B. Vajpayee and other eminent dignitaries
on 4 May 2003.
2005 - 1st December - PV-2 made her successful maiden flight.
2006 - 1st December - PV-3 flew for the first time for 27 minutes at an altitude
of 2.5 km and at a speed of Mach 0.8. PV-3 was equipped with a more

Tejas has an Advanced Radar
The coherent pulse-Doppler Multi Mode Radar is designed to operate equally effectively in
the Air to Air and Air to Surface domains. Jointly developed as an Indian – Israeli venture, it
features multi-target Air to Air Track, Hi Resolution Synthetic Aperture Mapping and
specialized Air to Sea modes. The radar facilitates all weather employment of a variety of
Air to Air and Air to Surface Weaponry, and is the primary targeting sensor on the Tejas.

could cost between Rs 750 crore and Rs 850 crore ($120-140 million) each.
Thanks & Jai Hind!!
SLEEP well my MOTHER... SLEEP well my FATHER...,another beautiful dawn is on its way

Tejas the light combat aircraft of india

  • 1. Light Combat Aircraft - TEJAS Made In India
  • 2. TEJAS Tejas is a lightweight multi-role jet fighter developed by India. It is a tailless, compound delta wing design powered by a single engine. It came from the LCA programme, which began in the 1980s to replace India's aging MiG-21 fighters
  • 4. TEJAS It is the smallest lightweight, multi-role, single-engine tactical fighter aircraft in the world and is being developed in single-seat fighter and twin seat trainer variants for the Indian Air Force and Indian Navy.
  • 5. Tejas Frugal fuel consumption and inbuilt air refueling capability
  • 6. Tejas She rockets off the runway and into the air in a mere 500 meters
  • 7. Tejas Dimensions Weights Aircraft Performance Wing Span 8.2 m Take off weight (clean) 9500 kg Max Speed Mach 1.6 / 1350 Kmph (CAS) Length 13.2 m Take off weight (max) 13200 kg Max ‘g’ +8 to -3.5 Height Overall 4.4 m Service Ceiling 15 km
  • 8. Tejas - Engine F404-GE-IN20 Dimensions: Diameter 890 mm, Length 3.9 m Weights: Max Weight 1,035 kg (2,282 lb) Engines Performance: Thrust 9,163 kg (20,200 lb)
  • 11. Weapons The Tejas is designed to carry a veritable plethora of air to air, air to surface, precision guided and standoff weaponry. In the air to air arena, the Tejas carries long range beyond visual range weapons, with highly agile high off- boresight missiles to tackle any close combat threat. A wide variety of air to ground munitions and an extremely accurate navigation and attack system allow it to prosecute surface targets over land or at sea with unparalleled accuracy, giving the Tejas true multi/swing role capability.
  • 12. The Makers • Also many Indian Public & private sector industries and academic institutions.
  • 13. Phases Phase 1 - TECHNOLOGY DEMONSTRATION STAGE (TD-1 & 2) The focus in this phase was on ‘proof of concept’. It entailed the development and testing of two technology demonstrator aircraft. These aircraft were called TD-1 and TD-2. The decision to move forward was to be taken after the successful completion of this phase. This would be followed by the production of additional prototype vehicles. There were teething issues during this phase and finally TD- 1 flew on 04 January 2001 with Wing Commander Rajiv Kothiyal on the controls. The significance of this golden-day in the history of Indian aviation can be gauged by the fact that the last time an indigenous aircraft had got airborne was almost 40 years ago on 17 June 1961.
  • 14. Phase 2 - ADDITIONAL TESTING PHASE (PV-1, PV-2, PV-3 and PV-5) This phase consisted of additional testing and development of systems using Prototype Vehicles which would lead to the development of the final variant that would join the IAF and the Indian Navy. The first Prototype Vehicle, PV-1 flew on 25 November 2003. By 2005, the Tejas had proven itself in the testing phase and the first order for 20 Series Production aircrafts was placed. A follow on order for an additional 20 SP aircraft was placed in 2010. Phases

It was decided that the programme will be implemented in two phases. 1990- Design of LCA was completed as a tail-less compound delta winged relaxed static stability aircraft. Timeline
  • 17. Phase 1 (Technology Demonstrator) was commenced to create the proof of concept. 1993 - Full funding approved from April 1993 and dev. work for phase 1 started in June. 1995 -First technology demonstrator, TD-1, rolled out on 17th November. 1997 -Multi-Mode Radar (MMR) for LCA design work started at HAL Hyderabad and LRDE. Timeline
