The impact of several scenarios for a future upgraded ATLAS detector is evaluated for the electroweak production of same-electric-charge WW boson pairs through vector boson scattering, ssWWjj-EW, at a High-Luminosity LHC at sqrt(s) = 14 TeV. Pileup suppression and identification of jets and leptons are evaluated for their impact on the precision of the ssWWjj-EW cross-section measurement. An extension of the forward tracking system from pseudorapidities |eta|<2.7 to |eta|<4.0 has the potential to improve the cross-section precision of the ssWWjj-EW by approximately a factor of 2 for a mean number of pp interactions per bunch crossing mu 200.
