The R-351 Mobura is Neucom's ultra high altitude transport aircraft, which they used during the middle of the war of 2045. The Mobura, while unarmed, can carry two R-311 Remora ultra-high altitude interceptors each. The R-531s commonly fly in large groups allowing them to disperse their R-311s in an effective manner, if attacked. The R-531s commonly operated within the highest layers of the Stratosphere, keeping them high above the combat envelopes of many General Resource LTD. or UPEO aircraft.
