Project Beacon, also known as Operation Beacon, was a Volkoff Industries undertaking, run by Alexei Volkoff.
It was first mentioned in Chuck Versus the Cubic Z, when Heather Chandler was questioned about the project after Chuck flashed on her association with it.
In Chuck Versus the Coup d'Etat, whilst in Costa Gravas, Chuck flashed on the nuclear weapons console Premier Alejandro Goya had secretly installed, revealing it was also part of the project. Goya willingly gave Chuck all of his files pertaining to Operation Beacon, while warning Chuck about Volkoff at the same time.
Behind the Scenes[]
The Project Beacon story line was a MacGuffin, which in dramatic terms, is an object, device, or event that is necessary to the plot and the motivation of the characters, but has no real weight otherwise. In this case, Beacon was simply another link in the chain eventually leading to Frost.
