IMTU there is a 10,000 DT limit to jump ships

[MarcusIII]

This has created (at least in how I extrapolated it) fairly stable interstellar polity boundaries because there is no such limit on non-jump ships. Making system defense ships so much more formidable than jump capable military ships. Trade in the frontier areas isn't as affected as in core areas where many more cargo ships are required. Less efficient to move mass amount of cargo.

In classic Traveller High Guard, the construction limit is 1,000,000 dtons.

Find a rationale why you have that limit, either physics or industrial base.

Yes, I played that back in the 70's

There is one. It is not possible to open up J space to any larger volume of craft. Just a physical law of J Space

Not so, there is an unlimited category above that. You need a model 8 or 9 computer and thus a TL of 14 or above but you then enter the realm of size code Z...
Y, or 1,000,000 tons, is the limit at TL13.
