Also they could do this, you know how when-ever the Legio Titanicus send's a group of Titan's down from a ship that is in orbit down to the planetary surface below? Well they cant air lift them down using standard methods because they are just too huge and too massive. The legio uses gigantic Bulk Lander's that are pretty much Dropship's for Titans. The Lander's drop into the planet's surface and begin's to descend.

From the book's that i have read about the Titan's a single bulk lander could hold up to a handfull of Titan's. So my best guess would be that they would put the already built and ready naval ship's into the hold's of these landers and then do the same thing's that they would do for the Titan's.
