They formerly competed in the Norwegian Eliteserien of the Norges Amerikanske Idretters Forbund, and the European Federation of American Football tournaments.
The founding name of the club was the Westside Vikings, and they immediately entered competition in the then new, three-team Norwegian American Football Federation league, joining the Vålerenga Trolls and the Kolbotn Kodiaks.
The highest body of the club is the annual members meeting, which elects a board for a one-year term.
The board, led by a president, is responsible for the day-to-day administration and football operations of the club, the budget as well as the long-term planning.
Associated with the Vikings, but with a separate board and organization, is the Viqueens Cheerleading and Cheerdance club.
