Well the Lada reports are real.
Of course they are real problems... and they have been dealt with... that is how the process works... you design something and then test it and then redesign it till it does what you want it to do and then you put it into service and production.
The Media like to play on the general ignorance of the populace and pretend that somehow these problems are not normal and will make the new product either inferior or ineffective, when the real facts are that every program has problems and the more ambitious programs often have the most problems.
The program is obscenely late and has had issues in pretty much every new system.
Unlike which program? The destroyers that should have been sailing by now, we should have had Pak FAs flying a decade ago, flying above T-95s which were so late they were cancelled.
I would think that by now the delays were understood to be perfectly normal... especially when the new system was replacing a very capable and popular system like a Kilo class sub.
Actually the worst case of a delayed program would be the bomber to replace the Tu-95 and B-52... in both cases we are still waiting.
The Su-34 issues was just Izvestya making a story out of nothing ( and of course making up some juicy problems as well ) .
You are assuming. I would be very surprised if they had no problems with the Su-34.
I don't even understand how the Nerpa issues became public. Who the hell thought that is the kind of thing media needs to know?
Nerpa was/is news... I would expect so called journalists would be hovering around like flies on droppings... recording and waiting for the smallest hint or complaint to blow out into a full article.
This is unpredictable India.. at your service..
Haggle for 10 years over a 2.5 billion dollar stopgap carrier that was urgently needed... Yep, I'd call them unpredictable... but as a customer you can afford to be picky.
I suspect despite any problems, real or imagined, they have already worked out that Nerpa is a good design and a useful sub.
