Concrete Submarines
Beneath the waves is a long way from Astro, however..... Ruminating upon the kurfuffle of the new French subs, in my mind arose a question.... "Why aren't the hulls of Subs constructed in concrete"?
The decade that style forgot, the 1970's a decade that delivered Glam Rock & Desert Boots, the 70's also gave us concrete sailing boats, quite a few of them.
Given that concrete is extremely strong in compression and that the foremost requirement of a Sub is that its resilient and strong under compression, why not build Subs with concrete outer hulls? Concrete is quieter acoustically than steel, titanium or aluminium, would it not be a better material?
I've a feeling there's more than one Naval Architect in our midst. My fingers are crossed for an answer to my question.... "Why isn't concrete used in building Submarines"?
