Series 1 Destroyers

[sneer]

I don't build ships below 10kt ( usually go in 10kt steps ) with 20-30kt most popular size for early to mid game
higher tonnage means I can easily put 2 or 3 weapon systems as loss of efficiency on higher tonnage is not significant
My fleet can be most often locked into 2-3 types of ships which I can refit if needed and which are all around ships
beams +gauss for 10/20kt and beam + gauss +box launchers for 30/40kt and bigger
knocking any ship out of the line in battle doesn't make any hole in combat capabilities  (sensor/offence/PD)- only percentage overall reduction
it is cheaper in the long run , easier in refits , easier with managing shipyards , and finally I don't loose many ships this way (smaller ships are really very fragile)

Yes... the survival ability of larger ships can't be understated as well as they are way better to withstand chock damage that smaller ships will have to deal with allot more often.

There's a problem with what imagery you get if you look at tonnage as displacement tons volume vs. tonnage as actual tonnage. . .

. . .Aurora armor mechanics suggest tonnage-as-volume. The engine mechanics might suggest tonnage-as-mass, but who knows how TN engines actually work? Their performance might be governed by volume rather than mass. Shock damage depends on ship tonnage, but I'm not sure whether that really makes sense for either interpretation. . .

. . .I think I've heard what Iceranger refers to the Traveller displacement ton. Not sure why we'd think that's what Aurora uses?

Aurora defines tonnage as a measure of displacement, not mass, and the armour calculation uses 'one hull space (50 tons) equals one thousand cubic meters' (10m x 10m x 10m) and assumes a spherical ship.  Engine mechanics use tonnage (hull spaces) -- and therefore volume -- to calculate speed.

I've never heard of the liquid hydrogen measurement before, but the "one hull space equals one megalitre of water" definition has been used.

If you go with 50t equal to 1000 cubic meters that is probably not too bad to imagine as it is not too far of the liquid hydrogen method.
