In the event that the Higgs mass is large or that the electroweak interactions are strongly interacting at high energy, top-quark couplings to longitudinal components of the weak gauge bosons could offer important clues to the underlying dynamics. It has been suggested that precision measurements of WLWL→tt̄ and ZLZL→tt̄ might provide hints of new physics. In this paper we present results for O(αs) QCD corrections to VLVL→tt̄ scattering at the International Linear Collider (ILC). We find that corrections to cross sections can be as large as 30% and must be accounted for in any precision measurement of VV→tt̄.
