At some point in the far future, humankind has sufficiently advanced to construct spacecraft for warfare, ie. space navies. The smallest of these crafts are comparable in size to contemporary fighter and attack aircraft, and are used as such. The largest of them, meanwhile, dwarf contemporary supertankers, and take on the roles of massive battleships, supply transports, or command centers.
The superpowers construct carriers to house, transport and launch their fighter spacecraft (or space fighters), much like contemporary aircraft carriers. Since space fighters require no lift to launch, they could be stored in individually designated pods, chambers or hangars, and a carrier could launch - and recover - its entire compliment of fighters simultaneously.
However, no matter the builders or the sizes of these carriers, all of them use one long, flat, exposed flight deck, combined with multiple elevators, to launch and recover their fighters, almost exactly like contemporary seafaring aircraft carriers.
What would be the reason to build spacecraft carriers this way, ie. in the image of contemporary aircraft carriers, instead of building corn-like carriers where each "kernel" houses a fighter, and could all be launched or recovered simultaneously?
