Pharaohs seem appropriate for our first heavy engineering ship, but I do like appearance-based names.
Agreed, IMO this design should go a long way toward strengthening the Federation. Quicker patrols, ability to provide assistance and move cargo, it'll make cultural exchange and personnel transfer less of a hassle, and help construct infrastructure or support facilities. Even though it doesn't have the sharpest teeth it should be well suited to building ties between members and solidifying core territory.
