Motivation is down but i present you here the XVB02 Vertibird from the game Fallout 3
The Vertibird is an VTOL (Vertical Take Off and Landing) aircraft designed for the United States Ground Force in the years leading up to the Great War of 2077.
The Vertibird, a tiltwing aircraft, was in relatively widespread use by multiple branches of the United States Armed Forces when the Great War struck in 2077, making wrecked examples of the aircraft quite prevalent throughout the wasteland. At an unspecified point of time after the bombs fell, a more advanced variant of the Vertibird known as the XVB02, still in prototype stage before the war, was placed in service by the Enclave, making it the first brand-new Vertibird model to be fielded after the bombs fell.
Following the war, the experimental XVB02 project was continued by Enclave members and loyalists, leading to the aircraft being mass-produced in large quantities and placed in full service as the general-purpose delivery vehicle of the Enclave's military forces. Capable of surgical insertions, extractions and close air support alike, the Vertibird is synonymous with the Enclave in general and representative of their power as a whole.
Vertibirds are known to have appeared on the East Coast in 2277, when the Enclave came out of hiding to secure Project Purity. It is unknown if the Vertibirds were brought over by the Autumn Senior, when he led the Enclave forces east, or had been sequestered there by the Enclave before the War.
