Training part is interesting, as the possible Hürjet-N will probably be the most powerful naval aircraft they will use anyway. Which brings a operational question. To train naval attack pilots, you also need a Hürjet-N trainer that is different than the LCA squadron. That's at least 20-25 aircraft there.
I think, first question is, what size of air force and sortie density is being targeted? Perhaps the naval forces may demand more than the number you speculate for training and combatants in total. Although our members who have clearly written about the risks and difficulties of the project are making very good points, if the goal is to create a significant naval air force starting, the preference for a maximum common platform that will benefit from a common logistics pool in the initial formation of this new air force may provide convenience in terms of operation, logistics, documentation and training activities.

Moreover, if this fighter jet is a successful development, I think this aircraft, with both versions as a STOBAR-attack jet and trainer, can attract the interest of small and medium-sized and with with low level of infrastructure facilities in the foreign market. Because one thing I am very sure of is that when this project comes to fruition, we will see really ambitious things on this aircraft in terms of avionics and weapon range. Especially on the machine-human teaming side.

For comparison, the basic characteristics of the aircrafts known in the world in the light attack role and in service, or soon to enter the active inventory (India's MK2).

HURJET Trainer ***[Light Combat Aircraft version to be developed later]
Wingspan: 9.5m (31 ft)
Payload Capacity: 2721 kg (6000 lbs)
Range (without drop tanks): 2222 km (1200 nm)
Service Ceiling: 13,716 m (45,000 ft)
Climb Rate: 39.000 fpm
Powerplant: 1 × F404-GE-102, 78 kN (17,600 lbf) thrust with afterburner

The right comparison should be Tejas Mk1A and not Mk2. Mk2 is a paper plane while 40 Mk1 is inducted & 180mk1A is on order.

Wingspan : 8.2m
Empty weight : 6560kg
Payload: 4500kg
Max speed: 1.8M
Ferry Range: 3000km
Ceiling: 15240m.
The empty weight is expected to decrease in Mk1A with matching increase in Payload due to removal of 400kg of ballast in the aircraft.

Of course, we are not as familiar with Indian aviation programs as you are, I had only concluded from open sources that the development phase of the mk2 was quite advanced, thank you for the additional information. As you can appreciate, the Hürjet is not ready either, my ideas are more about understanding what kind of systems will be in its class when the Hürjet is ready.

Tejas Mk2 is expected to see roll out end of next year. It’s under fabrication now.

Every program proceeds at its own pace. Payload increases are done over a period of time after sufficient testing & certifications. I remember during testing the Tejas had only 3500kg payload & limited G ceiling. After repeated testing, improvements in FCS, it is now 4500kg and G ceiling +9/-3.5.
It has also carried 5000kg payload, but will be released for operation after certification.

Hurjet will proceed on its own pace depending upon its requirements from TuAF. As one can see from the specs, it has designed purely as a trainer, to convert it into a full fledged light fighter, it would require significant modification. If that is what the TuAF wants, then it will go through the modification is my guess.

Do we need a light fighter? This is the question. I think we dont. There is no need to make Hurjet Combat version. But we can integrate our some air to surface missiles to use as a carrier platform when needed especially for saturation assaults. Som A-B variants, Tolun and KGK 82-83, TRG 230 maybe 300 etc.

Guys it's not about whether we need a light combat aircraft or not. It's about being able to build the goddamn thing! and many of them.

Yes we need Hürjet trainer version and when we have built 90-110 of them, the next question will / should be solved already....

Can we turn it into Light combat jet, the answer should be yes, and with little work as possible, TAF should have a minimum requirement for light armed jet, and that's what we should deliver to them (2-4-6 A2A missiles and mission comp to control KE etc), not change the fucking thing nonstop, halfway, through, every, fucking, comma!

Adding a pilot seat for purpose of conducting tests for the unmanned aircraft is not something new.

So Transforming UAV into manned appears not a big trouble which increases cost, design, etc.
Easy job

No it isn't, if you are trying to make an actual fighter out of a drone that is not going to endanger a pilot during a flight/war. Not to mention this thing has 1000 kgs of payload capacity, why would you want to risk a pilot when we already have two drones in work that can carry more?

Why are you so enamoured with this idea mate? What advantage a manned KE would even have over the original according to you?

I wish I were sitting in an air-conditioned room in ANKARA instead of an airplane to fire an A2A missile.
We are expecting aim260 and meteor equivalent a2a from TÜBİTAK and ROKETSAN.

If you guys only knew how beautiful I find Hürjet. Everytime I see her flying just makes it that much better.

Yesterday, the Hürjet was once again announced from the highest authority that a combat version will be developed and that this development will be a naval variant suitable for an aircraft carrier. In the light of this announcement, if we look again at the planes that were crudely compared above: The T/FA-50 system, which carries the same engine as the Hürjet and has a design philosophy very close to the Hürjet, lags behind the GE-F414 and Klimov RD-93's aircrafts in terms of climb capability and power-to-weight ratio due to engine limitations. As far as I know, Gripen E/F is the only one of these aircraft that can technically be operated as a STOBAR on the aircraft carrier, although it has not been proven yet. If I am not mistaken, the new Tejas will also have this capability in the future.

I assume that the landing gear of the Hürjet will probably be revised and the weight increase will be offset by structural lightening. It is not possible to know whether a single-seat variant of the aircraft is being considered by shrinking the canopy without changing the main fuselage, but in any case, the focus should be on increasing the total power output rather than lightening the aircraft.

HAL Tejas Mk1 Naval version has already landed on an aircraft carrier multiple times. Infact we have 3 prototypes. Testing will proceed and last we heard, integrations of CCM and BVR missiles are complete though it is yet to tested from landing/take off from aircraft carriers yet

However there will be no Tejas Mk2 Navy version. The research & lessons learnt will go into a new twin engine fighter with F414 engines. The plan is to develop naval version first & then develop AF version from the same.

Indian defence enthusiasts are asking IN or Indian MoD to buy 18 Naval Tejas as trainers. As they jump directly from normal trainers to Mig29k. Tejas naval version also participated in US Navy Trainer bid but was rejected as the bid was poor & had no local partner

Hurjet will start supersonic tests soon. The testing phase is going on at a great pace. TAI will probably complete all of the flight tests with a single prototype.
