Those of you who've encountered me before (probably somewhere else, since I keep forgetting to click the forum button when I visit Gateworld...) will know what I'm like with the whole thinking thing. I tend to do it an awful lot, and very quickly. A 5-minute trip to the bathroom can help me amass enough random thoughts to fill a volume in an encyclopoedia. So you'll have to forgive the random wanderings of my mind.
Warning - I've seen everything up to and including the end of Season 9 of SG-1, and Season 2 of Atlantis, so those of you who haven't seen that far may come across spoilers in some form or another...sorry if you do.
Okay. Here we go. I started off wondering about the "Daedalus-class". In Crusade, it was officially termed as being a "304". For sad people like me, that was an exciting moment - it answered the "Is the Daedalus actually the production version of the BC-303" question. That of course raises a lot of questions of its own - if the Daedalus was the next ship to come out of Earth's shipyards, why is it so different? Obviously, it incorporates new technologies, rather than being a test-bed like the Prometheus was, but back in Season 7, in Enemy Mine, they were harvesting Naquadah so they could build more BC-303's. While the Daedalus is cool, it is, as the ship patch for the Odyssey tells us, a "Deep Space Carrier". While every navy needs its carriers, why expend all the extra resources on building the Daedalus-class, when you've already got the tools, moulds and facilities lying around to construct another BC-303? After all, from the evidence, the only real difference between the Prometheus and the Daedalus is the number of engines, the number of decks, and the number of 302's it carries. Are we going to see a mixed fleet of 303's and 304's in the future, or is the Prometheus going to go the way of the 301, and become little more than a step up towards the class above?
That brought me nicely onto the Odyssey. There are several insteresting thoughts on that subject. The fact that Captain Marks, who appeared as Lieutenant Marks aboard the Prometheus in Avalon, and as Captain Marks the helmsman/bridge guy in Ethon, went on to serve in the same position on the Odyssey was a nice continuity touch. However, the real things that leap out are on the ship patch. First off, it classifies the Odyssey as a Deep Space Carrier. Since the Daedalus, The Odyssey and the Korelev are identical in every way, it's logical to assume that the designation applies to all. Does that mean that the Odyssey and the Korelev are DSC-304's? DC-304's? Some other variation on those initials? It's also worth noting that the Odyssey bore a "USS" prefix. USS means "United States Service", so technically speaking, the Daedalus and the Prometheus could have had that applied as well, but its the first time it's been shown on screen.
The other thing that leapt out was the fact that there is a six-digit alphanumeric sequence on the patch - PB3865. That's eerily similar to a SGC planetary designation - PB3-865 seems to conform with the pattern we've seen thus far. Being the sad person that I am, I've gone through the Omnipoedia on the Gateworld site. Having two letters next to each other in a planetary designation seems a little off. However, it's not the first time it has occurred:
PAS-A81 - seen on screen, "Prisoners"
PJ2-445 - crazy plant land, "One False Step"
PT1-AA1 - seen on screen, "Prisoners"
PWW-98C - seen on screen, "Prisoners"
PX3-595 - visited by NID, "Shades of Grey"
PX3-808 - Daniel Jackson and SG-6 gated here, "A Matter of Time"
PX3-989 - Altair, "Tin Man"
PX7-377 - The "Crystal Skull" planet (supposed to be P7X - quoted wrong in "Arthur's Mantle")
PX7-455 - alternate SG-1 came from here, "Ripple Effect"
PX7-941 - Madrona, "Touchstone"
PX9-757 - Apophis' shipyards, "Upgrades"
PXY-887 - trinium planet, "Spirits"
With that in mind, is it possible that the numbers correspond to an off-world construction site for the Odyssey? It would certainly fit into the timeline. If we use 18 months as a ball-park construction time for a 304, the Daedalus would have begun construction at about the time of "Enemy Mine" (when sufficient Naquadah was obtained). It would have been constructed in a silo, a la the Prometheus. When it was finished, the Korelev could have been constructed in the same facility, and was rushed out a few months early to be given to the Russians. Meanwhile, rather than go to the lengths of digging a new silo to hide the construction of another ship, the Odyssey was built on PB3-865, where the threat of it being seen by the general public is non-existant. It could have been towed to Earth by the Asgard so that its final systems (transporters, shields, weapons, hyperdrive, etc) could have been properly integrated by the people at Area 51. That would explain why the Odyssey was in orbit in Off the Grid, rather than being sat in a silo somewhere - equivalent scenes with the Prometheus would have had the ship underground.
That begs another question. What's going on with the planetary designations? I've heard several theories, some of which make more sense than others. Some people suggest that it might be a graphical representation of the gate address - 10 numbers and 26 letters. Unfortunately, though that ties in with the Pegasus galaxy (which has 36 symbols on its gate, I believe), thats a couple short of a Milky Way address. If it is some kind of grid reference, why is it divided up into clusters of three? Normally, the numbers/letters next to each other are collected, so that something like 139 represents "square one, subsquare three, subsubsquare nine", or something along those lines. However, Stargate addresses are grouped into two sets of three. Since everything begins with a P, more or less, could that stand for "planet"? If so, are the following two digits something to do with the type of planet it is? Maybe it's based off a birds-eye view of the galaxy, so that the two digits that follow the P correspond to the X and Y components of its position, with the others being sub-grids within that?
Any theories, counter-theories, or other thoughts on my thoughts? Figured I might as well say something to someone about them for a change. Lol.
