...and, turning the argument on its head, - they still made carrier happen because the need was there.
IIRC the shipyard which built the Vikrant never even built warships before.
But that doesn't turn my argument on its head at all because you're talking about something entirely different.
We were talking about the relationship between having a competent civilian shipbuilding and the ease and ability to better carry out large, complex naval projects like carriers.
I don't think I wrote anywhere that a nation *needed* to have a competent and capable civilian shipbuilding industry to build a carrier.
Instead, what I've been saying is that having a competent and capable civilian shipbuilding industry would make it a less painful process (less delays, less cost overruns, generally more smoother etc).
Obviously one doesn't need a competent and capable civilian shipbuilding industry to build a carrier -- after all the US builds the most capable carriers in the world and in greatest consistent numbers, and the US lacks a meaningful civilian shipbuilding industry compared to the East Asia giants.
However what I am saying is that if the US did have a competent civilian shipbuilding industry, it would almost certainly benefit their overall naval shipbuilding programs (whether it be carriers or other warship types).
