Anyone knows if python5 integration is only pylon/software change on already produced IOC/Mk1's or some more rework needs to be done?

No, if Derby is integrated then it's plug & play... basically the same missile with different seeker. The launching rails are slightly modified tho, with the Derby having another module for data link with missile.

HAL's production of 2 Tejas a year over the 2010-2019 decade hardly inspires confidence in their abilities as a fighter aircraft manufacturer.
👍👍👍

Please ask any other fighter manufacturer to mate Israeli Radar, Russian Missiles, American Engine with Indigenous FBW, not counting whims & fancies of Indian Air Force, in a tiny sized fighter jet. You will get shock of your life with their replies.

In that case who is to blame for ? Developer or customer ?

HAL didn't studied the plane. It was the DRDO job.
HAL just produce it at a pityfull rate.

Ask SAAB , with a US engine, US and european missiles, english FBW, non fully swedish radar. In a tiny sized jet.

They're all NATO countries. But that aside, you're partly right about HAL's bad performance. But you've also got to consider the fact that IAF isn't the best customer in the world. They keep changing requirements, and Tejas is the first aircraft of its class designed in India, there is a learning curve. There is also the partners of HAL delaying delivery of subsystems (again, nascent manufacturing ecosystem in India). It will get better with the maturity of the Military Industrial complex in the coming years.

I agree, but the record of HAL is really bad.

Usually in American jets I have seen that the missile is first dripped from the fuselage a few feet and then it ignites its motor, why that is not followed in Tejas ? Pros Cons ?
That has nothing to do with American jets per se.

There are 2 ways in which a missile can be fired.

1) Ejected from the pylon so that it drops and then the missile ignites.
2) Fired from the pylon rail itself

There would be various reasons for ejecting a missile- most relate to the position in which the pylon is placed. For e.g. AIM-54 Phoenix was always ejected and then fired it's motors after dropping a fair distance..the reason was that it was developed to be carried with the F-14 Tomcat, which carried most of it's AIM-54s on it's fuselage pylons.

Similarly, when a missile is to be fired by a stealthy fighter that is carrying it in it's Internal Weapons Bay, it needs to first eject the missile and then ignite the motor. In both cases, it can't be fired off the rails unless you want to lose the fighter that fires the missile as well.

AIM-9 series missiles and even AIM-120 AMRAAMs are fired off the rails as well as ejected. See the video below where an AMRAAM is fired off a rail and not ejected.

To restructure it ! But after all it's an indian problem.
Unions will resist , here right wing is socialist and left wing is socialist.
The central government tried to corporatize the ordinance factories which are 41 , faced stiff opposition from its own party union and the communist unions
Both aligned to resist it .
Privatization or corpotization is a taboo word here.
The government directly becomes friend of the rich, enemy of the poor etc etc.
Though india has 300 public sector companies .
Plus this central government has more welfare schemes for home loans , rations for poor ( public distribution system ) free schools or with token fee where free lunch is provided , along with medicines and other things necessary for healthy growth of children.
Free vaccination of new born children in government hospitals , universal health care scheme called ayushman bharat and many more schemes are there .
Cost of medicines is regulated, government buys crops from framers and payS them good .
All of the above since we are a sovereign socialist secular democratic republic .

Once again, you're right. And this is why Indian govt create a (small) competitor to HAL (thanks to the Rafale deal offset) so as to put some pressure on HAL to restructure it self !
India need a strong and efficient weapon industrial basis.
