The D.2 "Kadrei" (Spectre) Unmanned Combat Aerial Vehicle - Rotary (UCAV-R) is used by the Callentine Navy and is scheduled to replace the aging R.8C/D "Sea Shadow" attack helicopters on destroyers and cruisers (which carries two aircraft); however manned helicopters are slated to replace their Marine equivalents.

Retconned and colored from comments on the previous drawing, that it's way too heavy to fly and such.

Apparently I had the same idea as Sikorsky with the UAV application of the rotor system (which, in fairness, I adopted from them)
