This Month, HAL’s Intermediate Jet Trainer Gets Final Shot
Flight test of the Sitara ground to a halt in 2016 after it became clear that spin trials couldn’t be completed safely on the then airframe. HAL spent the next three years using advice from U.S. aviation technology and testing firm Bihrle Applied Research Inc. to redesign major parts of the aircraft’s tail end, resulting in significant airframe changes, first visible when the redesigned jet flew in April 2019.
...
“We have not given up on the IJT, in fact we have restarted the program,” HAL chairman & managing director R. Madhavan tells Livefist. “In the previous one year, we have started working on it. We have changed the airframe to improve the spin capabilities. We were waiting for a spin parachute so we can begin testing the new changes.”

Said to be cockpit of HJT-36. I am slightly suspicious as I remember reading here many times that 'Sitara' is not an official name. And 'Hal sitara' instead of 'HAL Sitara'. :?:

The name is on the image, written on it later, not on the cockpit panel, if thats what you are alluding to.

Per Wiki chacha 5 external hardpoints and can carry 1000 Kg payload
How many of these will ( if they ever will be) ordered and in times of need as A2G mode what can they carry?

Well, looking at the JL-8 which is the peer, she could be suitably armed.

OK.. The 'improvement' consultation engagements with Snecma, Smiths Aerospace produced an aircraft that got hobbled for almost a decade. Another improvement consultation engagement with Bihrle Aerospace leads to significant redesign.

In the meantime the Hawk is ordered and assembled.

Prime example of how Made in India projects are sabotaged. Left to itself and with incremental addition of capability, it would have been Sitara in place of Hawk.

None so far. News gone cold after incorporation of the spin recovery chute early July.

From Tarmak007's FB post ...

Modified IJT commences spin flight testing
(Unedited Press Release(
The indigenous Intermediate Jet Trainer (IJT) designed and developed by HAL to replace the ageing Kiran aircraft fleet of the IAF commenced spin flight testing in Bengaluru. The flight was piloted by HAL’s test pilots Gp. Capt H.V. Thakur (Retd) and Wg. Cdr P. Avasti (Retd).
The spin testing of an aircraft is the most crucial phase of its flight testing. Accordingly, the testing will be gradually progressed to assess the behaviour of the aircraft till six turn spins to either side to meet the targeted requirement
The IJT has already been tested to its full envelope in terms of speed, altitude and load factor (‘g’ envelope) and has also been integrated with drop tanks as well as bombs. For spin test, HAL redesigned the aircraft by moving the vertical tail aft and extending the rudder surface. These changes for ensuring a satisfactory spin behaviour required extensive redesign of the rear fuselage and the rudder. The changes have been incorporated in two aircraft with the involvement and clearance from certification agencies at every stage. Post modification, the two aircraft underwent significant flight tests to assess the general handling with the new configuration of fin and rudder. These aircraft have now been incorporated with the necessary safety devices (Anti-Spin Parachute Systems). During the first flight, initially the aircraft was taken through one turn spin to the left and right hand sides to test the spin characteristics.

The IJT was never in competition with the Hawk! That was the AJT,acquired after a 2 decade search,longest in any air force history,after the AM La Fontaine ( later ACM) committee recommended the same inquiring into the reasons for the numerous crashes of IAF aircraft. The Hawk deal was over long before the arrival of the IJT.

The IJT,supposed to be a Kiran replacement,was much appreciated for its swift development but infamously crashed in front of us on the runway at an Aero-India show. Later on the spin problem bedevilled it and it was put into cold storage for years.
Some air forces have only two kinds of trainers,ab initio and an AJT leaving out an IJT.The IAF however feel it's needed. The Pilatus PC-21 advanced trainer I think can simulate characteristics of advanced fighters and around 9 air forces operate it.I remember the editor of Flight Intl. years ago commenting v.favourably about the bird which is probably the most popular adv. trainer today, has excellent features. Our PC-7s are BTs,the most popular in the world with over 20 countries operating it. Like Bofors a great product marred by bribery and now being supplanted by our desi HTT-40.

Fingers crossed for the IJT to overcome its spin tests. If the IAF buys it ,it could find a niche in the intl. market if the price is competitive.
That is going to be the difficult task for exports, as we are used to generally paying higher prices for desi-built products compared with foreign equivalents. In a VAYU article,the SU-30 deal originally had an agreement with HAL that the desi- built aircraft would not cost more than $1M over an Ru- built one. There's a lot of competition in the trainer market.

Yes Nachi,the wing fences are new,seen from the pics.Reminds one of the good old SU-7s which had a prominent wing fence! Amazingly 140 SU-7s were acquired in them days in just 1.4 years! What a production rate!
