This is a pseudo repost of a detailed list i posted in another forum, showing all the prototypes, limited series and...well, every plane of the "test fleet". Hope you like it!
Testing Wings over india - Prototypes, pre-series and others
From the total airframes made till date of the indian LCA, only 24 belong to the two operational squadrons, this two being Sqd. 18 and Sqd. 45...but what about the 16 that remain...?
The answer to our question....a test fleet!
A bit of historical context
The final design of the LCA was consolidated by the end of the 80s much like the work that was undergone to familiarize with its power-plant (the F404 engine, india purchased 6 in 1986), the LCA program was taking shape. With the beginning of the 90s HAL would begin work on the initial examples, this being Technology Demonstrators (not prototypes).
Its worth noting that this extremely ambitious program brought with it a massive jump for the Indian Aeronautical industry, this meant millionaire investments in equipment, tech, training and infrastructure in efforts to face the production of the Tejas.
When the first demonstrator was about to be finished, the nuclear tests done at Pokhran stopped all work that was being done by US and other western companies, leaving HAL to "deal" with the incomplete fighter (at the long run, this would be beneficial for HAL). Years later in 2001 India would be able to put its first demonstrator on the air, marking a milestone on the LCA program, a year from that moment, a second demonstrator would rise to the sky.
With the lifting of the US embargos, HAL would start receiving spares and other equipment that would ease the production of aircraft, from that point on HAL would produce a large number of test units, even to this day. The reasoning behind the large number of units of this class might be given to the fact that multiple of this have different testing objectives (whether a radar, a refueling probe or any other system)
And the aircraft are:
Technology Demonstrators
(Name-markings)
TD-1 (KH-2001)
The first example to be built of the LCA, this started operations in 2001 and ceased years later after 233 sorties.
TD-2 (KH-2002)
Second Technology demonstrator, started operations in 2002 and ceased years later after 305 sorties.
PV-1 (KH-2003)
First actual prototype, underwent the first high performance and armament tests, started operations in 2003 and ceased in 2015 with a total of 245 sorties.
PV-2 (KH-2004)
Second prototype, started operations in 2005, currently grounded after 222 sorties.
PV-3 (KH-2005)
Third example with the prototype designation, started operations in 2006, currently grounded after a total of 387 sorties. This was the first example to perform night operations.
PV-5 (KH-T2009)
First two seater/trainer prototype, started operations in 2009, currently flying with a total of 291 sorties.
PV-6 (KH-T2010)
Second trainer prototype, currently operational with a total of 391 sorties.
Pre-Series
LSP-1 (KH-2011)
First pre series example, started operations in 2007 and ceased flying after 74 sorties, this particular example used a different variant of the F404 engine.
LSP-2 (KH-2012)
Second pre-series example, started operations in 2008 and still operational, amounting a total of 373 sorties. This example carried the definitive variant of the F404 that would be used in the series aircraft. (Today this plane is equipped with the UTTAM AESA radar)
LSP-3 (KH-2013)
First example to be equipped with the ELTA-2032 radar, started operations in 2010, it still flying amounting a total of 556 sorties. (Today is equipped with the UTTAM AESA radar)
LSP-4 (KH-2014)
First example to be equipped with the complete Mk.1 configuration, started operations in 2010, today it still flying, amounting a total of 532 sorties.
LSP-5 (KH-2015)
First example to consolidate the Inicial Operative Configuration (IOC), started its operations in 2010, today it still flying with a total of 573 sorties.
LSP-6 (KH-2016)
Currently being built.
LSP-7 (KH-2017)
Example used for tests regarding armament, it still operational with a total of 436 sorties.
LSP-8 (KH-2018)
Example that achieved the Final Operational Clearance (FOC), started operations in 2018, it still flying today after 348 sorties.
Naval aircraft...
NP-1 (KHN-T3001)
A Mk.1 trainer that underwent a major modification for its "Navalization", started operations in 2012, today it has amounted 200 sorties.
NP-2 (NAVY-3002)
Second trainer modified for naval operations, this particular one had its second seat removed, started flying in 2015, to date it amounted 156 sorties.
The total sorties of all test fleet aircraft amounts...5321 sorties!
