Concrete subs?

[Paul Anderson <hacker@geeky1.ebtech.net>]

I was in the magazine store the other day, and Popular Mechanics had a
blurb on a submarine made out of concrete.  That got me thinking about how
one could construct such a thing.  My idea is that, basically, you build
it up from two halves, each half starting with a steel plate fitting the
profile of the sub, rebar is then welded to it to create the essential
shape of that half, at which point the concrete is poured around the
rebar(probably using a mould).  When the concrete has set for both halves,
the steel plates are then welded together and internal hardware is them
mounted in place.  Any thoughts, beyond difficulty of transport?  TTYL!
