A medium or large transport with 2-4 drone launchers and stealth armor is great for hiding in an enemy system and using drones to pick off colony ships, transports, individual carriers, and small planets.

Drones work pretty well (even later in the game) when used in fleets together with large numbers of CSM's and fighters - one drone seems to be as effective as a couple of Groups of fighters, or several missiles in overwhelming the enemy's defenses.

Also, drones work fairly well defending planets when used fairly large numbers, and in support of fighters. If planet storage is an issue, build some transports with 2-4 drone launchers and as many cargo bays as possible, only adding one engine (and maybe solar panels) in case you need to move them some.

Those moon shipyards mentioned in another thread work good for building your supply of drones, use a few 'drone barges' for storage, and possibly suffling to near by planets since the moon doesn't have enough room to store them all.

When used independently against fleets, or against better defended planets; they don't have much use, but when used for combined arms tactics, or for picking off straglers, they are definitely worthwhile. (A transport full of drones is noticably more cost effective at that then a few destroyers or light cruisers)
