</font></div>
<div><font class="Apple-style-span" size="3">Now you're going to make me think a minute. Okay, it's like this. Each number corresponds to some common design theme or trait. The PC really did stand for Perry Cubmarine by the way, although they tended to downplay that later in the game.</font></div>
<div><font class="Apple-style-span" size="3"><br>
</font></div>
<div><font class="Apple-style-span" size="3">PC-1 & 2 were the experimental psubs style homebuilts, which don't really count here.</font></div>
<div><font class="Apple-style-span" size="3">PC-3: was the original fore and aft design and the first commercially viable (3 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-4 was the first successful diver lock-out boat, Deep Diver/Shelf Diver (2 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-5 a hybrid or transition design between the 3s and what was to come (1 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-6 & 7 had other names (I suspect Opsub was one and the transfer bell another.</font></div>
<div><font class="Apple-style-span" size="3">PC-8 the first bubble nose sub, 42" OD hull, twin battery pods (2 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-9 54" OD with lots of frustrum viewports (custom built for Brown & Root) (1 built)</font></div>
<div><span class="Apple-style-span" style="font-size: medium; ">PC-10 a 10,000' capable single sphere boat, never built</span></div>
<div><font class="Apple-style-span" size="3">PC-11 another design study, never built.</font></div>
<div><font class="Apple-style-span" size="3">PC-12 had 48" OD hulls, 28" conning towers, and twin pods. (5 built/4 obs, 1 DLO)</font></div>
<div><font class="Apple-style-span" size="3">PC-13 (something military we never got to see).</font></div>
<div><font class="Apple-style-span" size="3">PC-14 were 42" hulls, single releasable pods, low voltage, 24" conn. towers (2 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-15 was the second bubble nose sub built, a 54" OD hull with DLO (1 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-16 had three intersecting spheres for 3000 feet service (2 built)</font></div>
<div><font class="Apple-style-span" size="3">PC-17 was a huge, long range multi-task beast with bunks and a bathroom-never built</font></div>
<div><font class="Apple-style-span" size="3">PC-18 a 54" hull diameter upgrade on the old PC-4 design (6 built)</font></div>
<div><font class="Apple-style-span" size="3"><br>
</font></div>
<div><font class="Apple-style-span" size="3">The conning tower thing has to do with viewports. Six in the 24", Eight in the 28". All frustrum ports on all Perry subs are the same size (except the 16s, which are the same OD only thicker). The ARMS bells may have had a series number assigned but I never heard it. We also built a bunch of decompression chambers and sat systems both with and without bells, plus a parking lot full of wet subs, two underwater habitats and who knows what else. At any rate, I think it was 25 commercially viable free-swimming submersibles built over...um...I guess 20 years or so, along with all that other stuff. And then there came the ROVs, which I was not a part of. Perry was a world leader with those and (I think) the first ones to build a commercially available work class ROV for 10,000'.</font></div>
<div><font class="Apple-style-span" size="3"><br>
</font></div>
<div><font class="Apple-style-span" size="3">I got to tell you -- it was an exciting place to work. The thing is, we knew that we were making history every day. Yeah, we grumbled about the pay and bitched about the heat and all that, but there was just nothing like it anywhere (except in Vancouver at Hyco, of course, where they built (I think) 12 subs including Nuytco's Aquarius).</font></div>
<div><font class="Apple-style-span" size="3"><br>
</font></div>
<div><font class="Apple-style-span" size="3">Those were the days, for sure. And Hyco wins, as Uncle Phil assumed the mantle and carried on carrying on. Counting hard suits, I'd hate to even guess how many subs those guys have built up there in BC. Probably as many again as Perry and Hyco put together.</font></div>

<div>How do the Perry numbers work, is there more than one 1201 or is each sub assigned a specific number. </div>
