Building a fleet before a science-fiction war begins

Which science-fiction universe would you choose if placed in charge of ship construction before its story began?

Stargate is the preferred setting, with a developed Daedalus design. The alternative is advance mass production of Star Trek warships.

Stargate is the preferred setting, with time available to develop a better Daedalus. The Star Trek alternative would establish a working Defiant production program before Starfleet discovered a wartime shortage. The imagined output includes 250 completed Defiants and another 300 frames under construction. Around fifty Galaxy-class ships configured as fighter carriers and additional smaller ships would provide other roles. These figures describe a proposed fictional fleet, illustrating preparation and production depth rather than events in the stories.
