Actually Jacob according to the RAW in SS6 (pg4). In order to build a ship of SM+12 you would need an SM+18 shipyard ((SM+18) - 6 = SM+12) which is huge and would require some extrapolation. Which isn't too difficult but it would be very expensive.

As well if it were a brand spankin new design you'd need to use the new invention rules (p. B473) and would require Engineer(Spacecraft) with additional rules from SS6-pg5

Molokh: you have everything in Spaceships 6 pdf.

Actually, SpaceGurper, according to RAW, this formula is for production line inside a factory. You CAN build larger ships inside (if it fits), but it takes more time, and is more expensive. Read between examples on p.4

In SS6:
Internal construction can take place as long as you can fit the ship in either the "production line" e.g. the factory system, which is at SM-6, so a SM+15 mothership can make up SM+9 ships inside its factory for standard cost and assembly time.
OR
Assembly can be done inside the motherships hanger bay, as long as the finished ship can fit inside the bay. Therefore an SM+15 mothership with three Hanger Bays can manufacture an SM+13 ship internally with extra construction time (project treated as being 10x more expensive in manufacturing time(but same materials costs), with and assembly time of 8hoursxhull tonnage in man-hour terms, and then with the man-hour constraints of having 300 Work stations per bay)
OR
Assembly can be done outside the mothership at same 10x factory time,tripling assembly time (24 hoursxhull tonnage)

example:
you are building a SM+12 Battleship costing $11B, If you have a SM+18 sized Factory you can build this in: $11B / $150B/hr(extrapolated from SS) = approximately 5 minutes.

same ship, SM+15 sized factory, but with hanger bays big enough to contain it(actually just one at SM+15):
$110B (treated as x10 because of factory size) / $150M/hr = 733 hours 20 minutes manufacturing time and then 8x100'000 hours = 800'000 hours assembly time / 300 work spaces = 2666 hours 40 minutes of assembly time
Thus it takes 3400 hours to complete manufacture and launch
which is 141 days 16 hours.

Same Ship, with an SM+15 Factory, but with external construction:
$110B / $150M/hr = 733 hours 20 minutes manufacturing time
24 x 100'000 = 2'400'000 man hours construction time
What is not clear is what sort of work space requirements there are for outside construction, if it is purely manpower required, you could have 10'000 people working on the construction and it would take 240 hours, but assuming you have the same 300 people as above it would take 8000 hours, making total construction time 8733 hours 20 minutes which is approx. 364 days (with one day off for christmas ;) )
