[Guardians of the Galaxy] Why do the Nova Corps ships have the ability to link up?

It seems like there aren't a lot of reasons to use that ability. The Nova Corps can fight people in space when not ambushed, can put engines on any incoming asteroids, and wouldn't often need to stop someone from reaching the surface at all costs.
