I understand you're worried, so I'll explain it all the best I can.
First and foremost, absolutely nothing has changed IC between Origin and Yamatai - things are the same as they have been, even before the move in the forums. The shift of Origin out of the Yamatai Forum Subsection was intended primarily as an OOC effort to appeal to more players and factions of players on the site. We're trying to draw everyone together with our product lines - think of us as Swiss Wallmart in Space if you must. Though we're currently based in one nation, we've been impartial as possible between all, and we've dealt with Yamatai fairly in the past, haven't we? We still intend to do so.
Now, with that aside, on to wheeled and tracked vehicles.
These vehicles, though less mobile than the fast moving Power Armors in the Star Army of Yamatai's inventory, are intended for very specific roles. They are more heavily armed as well as armored, which is their tradeoff - for extended planetary invasion and conquest, which also involves plenty of urban fighting, these machines are indispensable for those very same reasons.
Powered Armors are the bread and butter of the site, and they remain so - what these vehicles are meant to do is
support them. There are several niches that are vital to a well oiled combined arms war-machine that aren't quite filled as well as they should be. That's why I've gotten to work on these vehicles. Here, for the tank in specific, the thing acts as a very hard hitting sniper platform out in vast wide open spaces, while providing close support fire against buildings occupied by enemy troops and their heavy units.
I also know that you specifically requested that new vehicles for the Star Army be hover, but there's a reason for why these are ground based too - it's for the sake of the story. Later on, there will be a hover conversion for these vehicles, but what you see here is more or less just the first production run; a Mod Mk 1 or some such will be released at a later date.
And since you bring up the question of a reliable supply chain, well, this is just the first batch for 5th Fleet to mess around with. Right now, the way I envision them being built is with all the Origin parts inside, but the Ketsurui Zaibatsu missing and awaiting installation, since those are all KZ proprietary anyways. If the players like having them around, and an improved, mass production variant requested, then KZ can get a license to build the whole things themselves.
But don't forget Dawn Station isn't too far away and in a place of safety, or that there's Sunrise Station too - it's right in the Industrial Sector!

On a side note, do take notice that there is a
Simulation Room Entry of these, something I did to have fun. As a result, the accounts are
not completely accurate, but if they were in a plot, I would have had them more worse for wear.
