It's not about whether the production is going to stop or not. It's about whether or not the official estimates by the Russian officials were realistic back in 2010/11.
Of course they were realistic, they were based on the information available and other plans in place at the time.
3 years ago most people would have bet money that France would have had the first Mistral class carrier ready for Russia last november... it was ready but was not handed over for reasons not really forseeable when the contracts were signed.
Now that we have entered 2015, we can see that many of those estimates were wrong. Therefore target of 50-70% of what was estimated a few years earlier, is more realistic now.
Reasonable to whom?
I prefer the Russian shipbuilders and military to release the plans and estimates as they have better information than bloggers and forum experts.
So the engine issue is not relevant here. What's relevant is to see how the Russian officials where hyping up their "production numbers", which won't be met by 2020.
So what you are saying is that it is the fact that they will probably have gotten their estimates wrong is the important thing... not why they might have gotten it wrong.
Will there be public trials, or just quiet executions?
While I do understand that technical problems might occur underway, it's interesting to see how much all procurements are delayed and by how much.
That is why it is called planning and management... you create plans with the best information available at the time, but over time you review the plans based on any new information and then either change the plan or change the management.
A good example was S-400 production which was found to be too slow to manage domestic and potential export production so extra production facilities not part of the original plan were created.
I am sure you will jump up and down and say the first plan was therefore a failure, but that is just normal management.
Current aircraft carrier should have been refurbished long time ago, but it still isn't.
Because they obviously decided they wanted to keep using it.
Speculation either way is pointless... it might be that they wanted to upgrade it with something that is not ready yet, or they might not have dry dock space available, or political reasons might have kept it in the water... we have no way of knowing.
Mistral LPDs won't be delivered, unless Marine Le Pen wins French elections in 2017.
Even if she does win they will both be very late by then and all the ship builders will have been tried and executed...
It is annoying to see the 8 by 2020 line repeated over and over, when it is clearly not true.
It depends on your standard of English... they planned to have 8 by 2020 and that is true.
Whether they get 6 or 10 wont be known till 2020.
Whining about it wont change anything.
