Okay, Since the DR was picked out of six aircrafts, why didn't India sign the contract then?
Just like it took SA 2 years to hash out a deal with the US on the F-15SA which would have involved discussions on costs, spares, training to air and ground crew , weapons, ground support infrastructure, sensor suite etc etc India has had to undertake similar negations with DR except with a great deal more complexity involved as ToT and offsets have slowed down the process significantly not to mention one-off issues like a work-share agreement tussle and the like. I can assure you Boeing isn't obliged to plough back
50% of the F-15SA deal into Indian industry so these DR-Indian talks have taken around 3 years (deal is now waiting for the next GoI to come in but is effectively closed) which is entirely understandable.
The 2-3 years before that were used for comparative trails and evaluations between the 6 entrants into the MMRCA competition. Again, the RSAF simply did NOT conduct as an exhaustive evaluative process as the IAF did- they may have conducted a somewhat thorough specifications review based on literature provided by the respective manufacturers but did they ever trail the respective bidding fighters in country or send their test pilots abroad to test the bidders in their home nations? Nope. The fact you can't even name the Russian a/c Robert Gates has speculated took part (btw highly predujiced source of information don't you think considering his nation's a/c won out) says a lot about the opaqueness of the SA election process. Again, I'll ask, did the RSAF have to compile 100s of page reports on each individual a/c judging 600+ parameters? The answer is a flat NO.
On top of all this throw in the fact India is a parliamentary democracy which has thrown up its own issues from time to time (countless probes have been ordered into the MMRCA selection process because the opposition parties called it into question, getting of absolutely scot-free every time but slowing the process down no end) whilst SA is a monarchy and for the most part would be negotiating with the USG (whom it has VERY close ties to). It doesn't take a genius to see which nation might be more efficient in this regard.
As for the industrial benefit we are getting, Al-Salam Aviation industry is taking care building several components, while Boeing is building others.
Again, I'm sorry but this is not comparable to the MMRCA competition at all. The MMRCA RFPs specifically outline that 50% of the contract will be plunged back into Indian industry over time, there is significant ToT and apart from an initial off the shelf delivery of a/c all fighters will be built in India by Indian industry with an increasing level of indigenous content.
Heck, Indian firms right now make components for Boeing (for F-18 and 787) without the MMRCA even going Boeing's way.
The F-15SA and MMRCA selection processes are chalk and cheese sir, there really is little to be gained in comparing them. If the media and certain people are unable to comprehend the sheer scale of the MMRCA's selection process then that is entirely their failing. Indians should be nothing but proud of the professional and thorough work that has gone into the MMRCA procurement and India, ultimately, will reap the benefits of this hard work....
According to former Defense Secretary Gates, the F-15SA was picked up out of three options i.e.the DR, a Russian aircraft. The RSAF was more comfortable with theF-15SA given the fact that we have been operating the F-15 for more than 30 years.
