Vertibird

"The Vertibird. We will save it for Skye to be the pilot of this chopper, in which she could pilot, because since her piloting was very good, I know she will use this for herself when it comes to piloting. I love this type of helicopter. It is my favorite. I wonder if I could use it?"

--Su Ji-Hoon, The Dogfight

The VB-02 Vertical Take Off and Landing (VTOL) craft, alternatively called the XVB02, codenamed "Vertibird," is a US military multipurpose tiltwing aircraft designed for the United States Armed Forces in the years leading up to the Great War, an event which changed the face of the world forever. Unlike in Fallout, it entered full-service, as ordered by Lily Loud, with numerous models were disseminated into various federal and private applications, and saw use in armed conflicts across the globe.

Background
The Vertibird, in the Fallout universe, and despite still looking in the prototype phase when the Great War struck in 2077, preventing it from entering full military service which was scheduled for 2085, in the Fallout world, it is offically in full service, as ordered by Lily Loud, the Commander of the United States of America. As evidenced by the crashed Vertibird on the roof of the Museum of Freedom an early prototype or version of the Vertibird seems to have been in use by the United States Armed Forces just prior to the Great War, though how widespread this use was is unknown. It appears the Commonwealth Coast Guard was also in possession of one before the war, as a destroyed Vertibird with Coast Guard insignia can be found at the Coast Guard Pier. Additionally, one flies over Sanctuary Hills just as the sirens sound in Boston, ordering the evacuation to Vault 111 by megaphone.

That Vertibirds were in use is further supported by the appearance of a prototype Vertibird with winterized camouflage during the Operation Anchorage simulation dropping U.S. troops before taking off again. However, whether any Vertibirds were ever used during the Alaskan reclamation is uncertain as General Constantine Chase was known to implement his own, fictional content to the simulation.

Following the war, the trial aircraft that were already produced and in the field were seized by Enclave members and loyalists and either transferred to their bases or secured in shelters. The Enclave began mass-producing the design in secret, and now the Vertibird is 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 a good representative of their power as a whole.
