</font><div><font style="background-color: transparent;">Have a look at the massive changes to The Great White by the Scotts (Cassell and Reed). Big deck, good sized MBTs, etc, and still keeping the weight to about normal (1 1/2 tons according to the web site. Maybe the broad deck lets them scramble in and out--if not with impunity, then perhaps with care. As to canting the dome, I think you could heavy up the mating ring so that it was strong enough to weld elliptically to an angle cut conning tower cylinder and with a good dome, you could push on deeper, certainly to the K-350 and maybe to the K-500 ranges. Still have to fiddle up an internal/external closure for it, though.</font></div>

I remember having researched this issue once upon a time, and I remember it giving me fits finding it. It's the same navy facility in Md mentioned by Alec , "<span id="yiv6360293448misspell-9" class="yiv6360293448mark">Calderock</span>," only he took it a step further having actually called them. It's very hard to find on the website, it's listed under laboratories and facilities as the "deep submergence test facility." <a href="http://www.navsea.navy.mil/nswc/carderock/pub/what/facilities/facilities_list.aspx" shape="rect" rel="nofollow" target="_blank">http://www.navsea.navy.mil/nswc/carderock/pub/what/facilities/facilities_list.aspx</a><br clear="none">
<br clear="none">
Elsewhere on the site you can find the agreement and cost analysis forms to download. <br clear="none">
So Alec has discovered the prohibitive cost which puts an end to it in my book.<br clear="none">
<br clear="none">
It turns out that the best case scenario for a test facility for us <span id="yiv6360293448misspell-10" class="yiv6360293448mark">PSubbers</span> is a guy in B.C., with a crane and a
barge, (imagine that!:)! At 27k mentioned by Alec, It would be more cost effective comparatively with <span id="yiv6360293448misspell-11" class="yiv6360293448mark">Calderock</span> for a guy from Miami to drag his little <span id="yiv6360293448misspell-12" class="yiv6360293448mark">PSUB</span> on a trailer all the way to B.C., with his wife in tow for a little dip in a local lake and one heck of a sightseeing vacation!!,...Ha!<br clear="none">

<div>As Vance says, HY80 is somewhat challenging to weld – err, actually, that’s an understatement. We had to work with our fabricators to come up with a whole weld procedure to satisfy our classing agency. If you decide to go this route, let me know and we will share that procedure.</div>

It occurs to me that if there was a demonstrable benefit to A537, he would have used taken advantage of it. And he didn't, apparently. Interesting. Don't know why, though.
