Before develope Tejas Hindustan Aeronautics Limited (HAL) developed India's indigenous supersonic fighter aircraft HAL HF-24 Marut. The Tejas is the second supersonic fighter developed by Hindustan Aeronautics Limited (HAL).
Journey of Tejas
In the 1980s the Light Combat Aircraft (LCA) programme started.
HAL Tejas characteristics
A review committee was formed in May 1989.
In 1990, the design was finalized.
Phase-I: In April 1993, HAL started on proof of concept and design development and testing (DDT).
First of demonstrator aircraft Tejas TD-1 flew on 4 January 2001.
Phase-I was successfully completed in March 2004.
Phase-2 started in November 2001, Three prototype (PV-3, PV-4 and PV-5) were developed.
By mid-2002, the MMR had reported suffered major delays and cost escalations.
On March 2005, the IAF ordered for 40 aircraft.
On 25 April 2007, Tejas LSP-1 performed its maiden flight and achieved a speed of Mach 1.1
On June 2008, LSP-2 made its first flight.
In November 2009, the trainer variant prototype made its first flight.
In 2009, Tejas achieved a speed of over 1,350 KM per hour (840 mph) during sea level flight trials in Goa.
On 23 April 2010, Tejas LSP-3 made its first flight with a hybrid version of the Elta EL/M-2032 multi-mode radar.
On June 2010, LSP-4 took its first flight and get Tejas got an IAF Initial Operating Clearance (IOC) configuration.
Phase-2 was successfully completed By June 2010.
Tejas received IOC on 20 December 2013 and IOC-II on 17 January 2015 and FOC is expected by mid-2019.
