Electron-impact excitation of argon ions is a vital component in the modelling of fusion tokamak experiments. Currently the available electron-impact excitation rates for the argon isonuclear sequence are a collection of isolated calculations carried out within various theoretical scattering models. With the development of our parallel suite of Breit-Pauli codes and the accessibility of massively parallel architectures, there was the opportunity to calculate the entire argon isonuclear sequence and provide a single, comprehensive and complete excitation data set. These data will subsequently be archived as Maxwellian averaged rate coefficients. We report on Breit-Pauli R-matrix electron-impact excitation calculations that have been performed for Ar3+, Ar4+, Ar5+, Ar7+, Ar8+, Ar10+, Ar11+, Ar12+, Ar13+, Ar14+ and Ar17+. Together with existing R-matrix calculations, this completes the generation of excitation data for the argon isonuclear sequence.
