Limited Series Production (LSP) aircraft
Currently, 28 LSP series aircraft plus 20 aircraft are on order.
* LSP-1 (KH2011) - 25 April 2007
* LSP-2 (KH2012) - 16 June 2008 This is the first LCA fitted with GE-404 IN20 engine.
* LSP-3 (KH2013) 23 April 2010 The first aircraft to have the Hybrid MMR radar and will be close to the IOC standard.
* LSP-4 (KH2014) - 2 June 2010 The first aircraft that was flown in the configuration that will be delivered to the Indian Air ForceIn addition to the Hybrid MMR, the aircraft also flew with a functioning Countermeasure Dispensing System
* LSP-5 - (KH2015) 19 November 2010 In addition to all the systems fitted in LSP-4, it will have night lighting within the cockpit, and an auto-pilot.
* LSP-6 to LSP-28 - Planned to fly by late 2010.
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 revised Indian Air Staff requirements given out in 2004-6 period, which required use of more heavier AAM (R-73 to R-77) and ASM and also capability to carry heavy and large bomb load . Tejas MK-2 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 2013-14 period and will be powered by Ge's F-414IN engines 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
* LSP-1 (KH2011) - 25 April 2007
* LSP-2 (KH2012) - 16 June 2008 This is the first LCA fitted with GE-404 IN20 engine.
* LSP-3 (KH2013) - 23 April 2010 first aircraft to have the MMR
* LSP-4 (KH2014) CMDS Trails
* LSP-5 (KH2015) IOC standard with all sensors inculding MMR and HMDS ,Radio aid will be used for Weapons Testing
* LSP-6 will be used to increase the AOA
* LSP-7/8 will be given for user trials
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.
