Heh, you've really spotted my weakness in NRP's: this kind of technical, non-political history is something I just really don't have. I'm kind of aware that 'making sense' is great, but part of me has the attitude of 'this is fiction' - particularly given the maximum that sufficiently advanced tech is indistinguishable from magic, and this is hand-me-down sci-fi from the nation's forefathers (ie: a pre-war find. Maybe you missed that?). Sure, in the real-world, blowing up a warship just isn't really a thing with a tank, and I take that as read - but this isn't the real world.

The reason I'd like it to be a stupidly oversized vehicle is because it's stranded on an island, both nerfing itself and seeming faintly ridiculous at the same time, while also guarding the vulnerable island at least by discouraging people from trying it on. If it was itself replaced by a warship, that's something that could actually have a practical offensive function, which isn't what I'm going for here. Meanwhile, if it was simply a big fuckoff cannon, somehow it loses something of the compensating-for-something vibe that I feel that a comically oversized vehicle that is also an archaeological heirloom has. 

I'm reminded of the battleships that the UK has in the Thames; there was a headline a few years ago about how a boat in London could hit something in the North of the country, if it so chose.

I feel like this might be the key line, assuming anything quite so powerful isn't off the cards by virtue of being OP: the reason it's impractical is because it's so unlikely to hit. But if it [i]does[/i] land a hit, it's gonna sink something.

[@Jig]I will create a map of Oceos when I get time using a cropped version of the GMs map. The Oceons might designate routes for your trading vessels and may occasionally monitor traffic,but they will have enough problems as island dwelling mutants, so they won't want any trouble.

Awesome. I'll peruse your sheet as I write mine and double-check certain things with you.
