Abstract: We investigate configurations of rational double points with the total Milnor number $21$ on supersingular $K3$ surfaces. The complete list of possible configurations is given. As an application, we also give the complete list of extremal (quasi-)elliptic fibrations on supersingular $K3$ surfaces.
