Well Vepr...
I am quite speechless of your album!
I think you took me as close to an Akula (yes, I prefer the Russian designation) than I will ever get!
Thank you.
Thank you also for having commented most of the pictures, and I especially loved the interior ones and those of the details on the outer hull.
Ultimately, I come to agree with what is written about their cost and that they can be (part) of the reason the economic system in the USSR collapsed. To it I would add another great example: the Buran Space Shuttle. When I was in Baikonur a few years ago for work, our tour guide of the museum told us that the cost of manufacturing a SINGLE thermal insulation tile was equivalent to the YEARLY pay of a senior officer, e.g. a Colonel or Lt. Colonel, and there were tens of thousands of tiles on each of the Buran. Furthermore, from indipendent readings, it is clear that the Soviet space agency did not have any clear purpose for the craft and ultimately the main reason for it being built was: the Yankees have one, they claim it is not a weapon, we do not know for sure, so we better have one!
I also agree (partially because I do not have all the elements) with your statement about Russian submarines beeing ahead of the west, but I am surprised you did not mention "unconventional detection/tracking sensors", like SOKS or similar. Or supercavitating weapons like the Skvall (well, mainly the technology behind it, as they were really "last resort").
In a way this is again also true for the space program: quoting the Buran again, it was capable of a fully autonomous landing, but then there are other great examples like the Venera landers, the MIR, and finally the Soyuz rocket and the Soyuz capsule (with the automatic randezvous and docking pioneered in the early eighties).
I just hope that in these days of the oligarchy and super-tycoons of natural resources, the country is indeed stil investing in (applied) science like it did successfuly for so many years in the past.
