A very simplistic drawing of the USN Fleet class USV. Apparently they did missile launching tests from one recently, but havent found a pic of one with the weapons packages onboard. They're designed to match the weight and handling limits of a rigid-hulled inflatable boat. Think mine might be a bit larger than actual SB scale.
colo has an point here. but I will step up for that now, as I am one of the few people who have drawn an USV before (the protector, to be exact) and as the one who planned to do quite a few of these USN USV's when better resources came available.
first of all, references.

from these, I can make a few comments now already.
- yes, it lack details, but first try to get the basic shape correct. in a quick search, I did not find the 2 versions you seem to have, but I might be wrong on that.
- an unit like this must have an underwater hull on the drawing. it will most likely be used placed on the deck of our ship drawings, so without an underwater hull it cannot be used.
- try to show some of the shape. right now, these could have landing craft hulls, as far as we can see.
- then add detailing, indeed.
good luck!
