I had in mind a reconnaissance craft when I designed this - you can see the black dome for the camera (I should add some more visible sensor packages, mainly white spheres and stuff) I don't really think it has the payload capacity for weapons. Certainly not internally.
I also didn't design it with VTOL capability, either. From what I remember of the descriptions, it's actually the UN that takes care of the UAVs, and all the Phalanx commander does is ask for a base to be set up at a specified location.
I just realized it could probably be launched from a flatbed truck, either railgun or rocket assisted, then recovered in a nearby field. This UAV can be only 4-5 metres long. The smaller size would make it much more mobile than a larger craft with VTOL - all you need to do is helicopter out a couple trucks for the launch platform and command station, maybe some extra fuel, and you've got a new operating base.
