Ship Construction Times

But add in power plant and fuel (at TL9-12) and it gets worse.
LBB2: 10+4 (drives) plus 20+20 (fuel) for 54Td; LBB5 @TL9-12: 3+6 (drives) plus 20+2 (fuel) for 31Td. LBB5 saves 23Td for Jump+Power+Fuel.
At TL-15, yes.

Compare size and cost at TL-11 for the Scout, or TL-9 for the Free Trader...

Sorry, I missed that.

But do compare costs too...
Not just cost, but the resulting operating cost per ton of payload. The Type S is really screwed over by the 10Td/Pn rule... and while you can build a 6G non-starship in LBB2, it's pretty much useless. Try it! At least you can use a standard hull... :)

Agreed. The Scout may be a special case as it's never going to be profitable, it's more about the cheapest price to get into space.

The Type S is really screwed over by the 10Td/Pn rule...
I believe that's the point: Small ships are supposed to be inefficient in LBB2, punished by the fixed tonnages, like the bridge and PP fuel.

LBB5 eased up on that punishment.

and while you can build a 6G non-starship in LBB2, it's pretty much useless. Try it! At least you can use a standard hull... :)
Worse than a Ship's Boat at over thrice the tonnage and twice the cost, no thanks...
 
So, compare a LBB2 Scout vs. a LBB5 Scoutish:

The LBB5 Scoutish costs more to buy and more to operate, but less per Dt payload.
If you try to operate it as a Merchant, it will lose more money per jump.
