The XHA-230 is a attack helicopter. Armed by one 30mm cannon (looks like GAU-8 Avenger), two 12.7 machinegun, also have 4 hardpoints for diferent kind of ordnance and two air-to-air missiles. Twin-fuselage design justified by the desire to put away cannon from avionics. Gun ammunition drum located in the center between fuselage below engines.
Used intermeshing rotors design, looks like as helicopters by Charles Kaman.
