If you look at the number of design iterations it took for Tejas Mk1 to evolve into the definitive Mk2 version, you can well imagine the analysis paralysis at IAF HQ. Rather than choosing an incremental roadmap, Mk2 was turned into a whole new MWF class fighter.
Granted threat perceptions dictate design requirements which change over time. But for an AF that is already down to 29 sqns, it is an open invitation for more trouble down the line.
That is not all. In 2018, the IAF held up clearance for Mk1A at the last minute to demand even more changes (reprofiled canopy, DMG, new MC, etc). These were non-critical changes that could have been integrated post induction. Contrast that with the Rafales which were inducted without ISE mods integrated.
Look the whole idea behind LCA mk1 (as it was originally conceived) was to provide a point defence interceptor with secondary ground attack capability. It does that job well. On the industrial side, we need to build critical production mass before transitioning to Mk2/AMCA.
In any case, we're replacing about 400 late-model MiG-21s with just 220 Mk1As.
We've been over those issues in the past. The LCA program was far too ambitious for Indian industry.
But our troubles began the day Kaveri was decoupled from the Tejas program, ostensibly to speed up induction. That locked us in with GE and gave the US leverage over a critical program.
But as they say, hindsight is always 100%. So I won't argue this point any further.
There is no doubt that the current RM is incompetent. Meanwhile the IAF Chief is now talking about having done his 'homework during MMRCA' while the MRFA RfP is yet to be released.
