The cross-section for the process e+e- ->W+W- has been measured with the data sample collected by DELPHI at an average centre-of-mass energy of 189 GeV and corresponding to an integrated luminosity of 155 pb(-1). Based on the 2392 events selected as WW candidates, the cross-section for the doubly resonant process e+e- -> W+W- has been measured to be 15.83(+)(-)0.38(stat)(+)(-)0.20(syst)pb.
