The delays in making timely decisions and the PSU's consistent inability to deliver on time persist.
Emergency was one such example. So was the Maoist movement, one was violently crushed in 1971 by IG, and then, until the end of the SU, Naxalism had spread to the rest of India, which was once again crushed violently throughout the 90s. AFSPA helped protect NE states, and the Mamata/Vajpayee combine defeated the Left in WB.
Then, after Congress came back to power under MMS, Naxalism rose once again, but it was controlled by Chandrababu Naidu with his Greyhounds and then was crushed by Modi. It was done by using demonetization and some more violence as usual.

In addition to the plug, ADA studied a bulged canopy to improve area ruling even further. The combined effect was 6 percent lower supersonic drag, which in turn led to a 20 percent improvement in transonic acceleration and 2 percent improvement in maximum speed [4].

Similarly, it was observed that there was a sudden kink in the aft bottom of the fuselage in Mk1 as shown in Figure 3. By eliminating this kink and identifying an optimized smoothened aft fuselage, an improvement of 4.9 percent was predicted in the supersonic drag on the aft body region.

A substantial amount of effort was directed towards optimizing the air intakes. The impact of changes in lip and cowl geometries, contractions ratio (i.e. the ratio of air intake to the minimum area of the intake duct) and performance of a newly proposed 3-door auxiliary intake were studied. The goal of these studies was to improve pressure recovery at low speeds without adversely impacting spillage drag at high speeds. It was found that the lip geometry and variation in contraction ratio of these features have minor improvements in low speed regimes, but their attendant side effect on high speed performance was deemed to be too high. On the other hand, cowl geometry optimization showed good improvement in pressure recovery due to its positive impact on the local flow field near the inlet plane. The 3-door design further enhances the gains in pressure recovery. It’s also expected to facilitate improved flow rates through the auxiliary intakes during the low speed, high AoA regimes. The combination of optimized cowl geometry and 3-door design results in a 3 percent improvement in pressure recovery, which should lead to an equivalent improvement in engine performance [11]. The 3-door design can already be seen on LCA Navy Mk1 prototypes.

Vertical fin of tail : there is change in RWR position to wing tips, ( read in twitter, like the position in mirage and mig 29 )
And some antenna is moved bit down..
What improvements can we get from that..?
Man! this sucks
Our private sector involvement in making various sections of fuselage is from Mk1A onwards or in Mk1 itself?
There is no news about their contribution ..
----++++++
Twitter feeds are filled with politics filth..
I think I better stick to forum alone , until elections are over.
Without JV not possible, one should learn from past mistakes , most of the air force projects are doomed due to lack of engine technology. LCA Mk2 and AMCA Mk2 should have same engines, (stealth compatible ) have to wait another 10 to 15 years most probably for first engine. Long way to go.
Man! this sucks
AMCA and Mk2 will have the same destiny as of LCA Mk1. I am pretty sure. Haven't learn anything from GTRE Kaveri crap and mismanagement of Marut project.
We are in China's 90s phase... they were building jets and even developing designs but they did not have the complete supply chains. It will take some time to get more thing in country.
The bigger problem with us is that we do not have that huge of requirement that we can keep these companies afloat with constant orders. Either India will have to start picking up more wars. or somehow start selling weapons cheap into world's conflict.

Post elections, you'll hear about AMCA's engine JV.
We've learnt everything. That's why GE-F414 is being licensed manufactured with 80% TOT and new 5th gen engine JV will come up soon.
China just assembled Su-27 and called it J-11 in the 90s, lol. In comparison, Tejas is a grounds-up, all new design. Only from mid 2000s(2005 to be precise) they started to induct their all-new fighter(J-10).
All of the above are a real possibility.
One more thing that is going under the radar is the presence of wideband digital RWR in Tejas MK-1A. It can intercept frequencies between 1 GHz to 40GHz and along with our new GaN ASPJ pod, this enhances EW capabilities of our "humble" LCA to nearly as good as SPECTRA, to say the least.
I guess they are excited about aspj pod prospects.
China's J10 program which started in 80s and had first flight in 97 (and probably based off LAVI) comes to mind.
If MRFA is being cut, then 189 AMCAs are not enough. Need 75 more.
Our Tejas program started in the 90s(realistically) and made first flight in 2001. China made jump from J-10 to J-20 and now domestic engines like WS-10 etc. Equally we'll also make the jump from Tejas to MK1A to MK2 to TEDBF to AMCA to future 6th gen and hopefully our own engine too. Within next decade most of the above will become a reality if not all.
Buy 75 F35 outright and be done with it.
Or
Buy 120 Rafale more and be done with it.
I'm not a huge fan of the F-35A, it still needs to move a bit further into the years first. And it turns out Rafale F5 is only possible after 2035, so it needs to bridge the gap between the current F4.1 and the F5. Both are realistic only after 2030, and the F5 isn't realistic at all at this point, it's 11 years away. By then relying on imports may end.
Buy 36 Rafales, order 2 additional squadrons of Su30MKI over the existing 12 airframes order.
Divert all funding towards LCA Mk1A & Mk2. And AMCA.
If you are indigenizing flight control laws (which is costly task) of MKI, you are not doing it for just addition 2 squadrons.
F-35 is not like, you sign a piece of paper, and voila. The complexities in buying F-35 are much much greater.
