The HAL Tejas is a 4th generation lightweight multirole jet fighter being developed by India. It is a tailless, compound delta wing design powered by a single engine. Originally known as the Light Combat Aircraft (LCA)—a designation which continues in popular usage—the aircraft was officially named "Tejas" by then Prime Minister Atal Bihari Vajpayee.
The IAF is reported to have a requirement for 200 single-seat and 20 two-seat conversion trainers, while the Indian Navy may order up to 40 single-seaters to replace its Sea Harrier. During its sea level flight trials off Goa, Tejas notched a speed of over 1,350 km per hour, thus becoming the second supersonic fighter being manufactured indigenously by Hindustan Aeronautics Limited after the HAL Marut.
Status
Tejas trainer under construction.In March 2005, the IAF placed a 2,000 crore (US$ 434 million) order for 20 aircraft, with a similar purchase of another 20 aircraft to follow. All 40 will be equipped with the F404-GE-IN20 engine.The Tejas is presently undergoing flight testing. It will be inducted into the IAF when it has received Initial Operating Clearance (IOC) which is expected to be in December 2010. Consequently, the IAF has created a 14 member "LCA Induction Team" stationed in Bangalore that is composed of IAF pilots and officers and headed by an Air Vice Marshal. The team's objectives are to reportedly oversee the induction of the LCA, help solve any challenges that may arise, assist HAL in customizing the Tejas for operational use, and to create doctrines, training and maintenance programs and finally to assist the IAF in ensuring a smooth introduction of 'Tejas' into operational service.
HAL Tejas high-altitude trials at Leh successfully completed by December 2008.The first production variant of the 'Tejas' (LSP-1) flew on June 2008. Tejas completed 1000 Test Flights by January, 2009 with more than 530 hours of in-flight testing. By February 2009 officials of the Aeronautical Development Agency stated that the Tejas had started flying with weapons and integration of radars would be completed by March 2009. In addition, they stated that nearly all system development activity would be completed by that time. On April 2010, the third production aircraft (LSP-3) flew with a hybrid version of the Elta EL/M-2032 multi-mode radar and by June 2010, the fourth production aircraft took flight in the configuration it would be delivered to the Indian Air Force in. By June 2010, Tejas had also completed the second phase of hot weather trials. The objective of the hot weather trials was to prove that the aircraft was in an IOC configuration with the weapon system and sensors integrated.
The trainer variant prototype took to the skies in November 2009. In December 2009, the Indian government sanctioned 8,000 crore (US$ 1.74 billion) to begin production of the fighter jet for the Indian Air Force and Indian Navy.The Indian Navy has a requirement of 50 Tejas and the first protoype, NP-1 was rolled out in July 2010.[46] IAF had ordered 20 additional Tejas fighter jets and the defence acquisition council had cleared the plan.
Planned production variants
- Tejas Trainer – Two-seat operational conversion trainer for the Indian Air Force.
- Tejas Navy – Twin- and single-seat carrier-capable variants for the Indian Navy.
- Tejas Mark 2- Featuring more powerful engine and refined aerodynamics.
The Tejas Mark-2 expected to be developed due to the inability of the Mark-1 to meet the Indian Air Staff requirements,will have a more powerful engine, refined aerodynamics and replacing other parts to reduce obsolescence according to an IAF spokesman. The LCA's naval variant would be ready for carrier trials by 2013 and is slated for deployment on the INS Vikramaditya as well as the Vikrant class aircraft carrier.
Some of features of "Naval LCA Version":
- Aircraft carrier operation with ski-jump and arrested landing
- Nose drooped for better cockpit vision
- Additional aerodynamic features like LEVCON and fore plane to reduce carrier landing speed
- Maximum take off weight from carrier—12.5 tons[vague]
- External store carrying capacity from carrier—3.5 tons
- Strengthened fuselage
- Stronger undercarriage due to higher sink rate
- Arrestor hook for deck recovery
- Fuel dump system
