S.T.R.I.K.E. first appeared in Captain Britain Weekly #17 and was created by Gary Friedrich and Larry Lieber.

S.T.R.I.K.E.'s original headquarters, as seen in the organization's first appearances, was an undersea air base which contained several of S.T.R.I.K.E.'s planes that were considered superior to their American counterparts at the time.^[1]

S.T.R.I.K.E.'s Psi division had their own headquarters.

Another headquarters was in a closed university, located in London, England; this headquarters was later used by D.U.C.K (Department of Unknown and Covert Knowledge).^[2]

Like S.H.I.E.L.D., S.T.R.I.K.E. had hundreds of agents throughout several divisions.
