The importance of UV interferometry at a resolution of about 3 milliarcseconds (MAS) down to a magnitude of about 15 for the study of hot stars is discussed with special attention being given to the winds of early type supergiants, the disks of Be stars, X-ray binaries and supercompact clusters. The number of objects to be resolved at this resolution is small (less than or equal to 20) but the information to be obtained is unique. Tables showing the following are presented: the relation between the radius of stars of different types and the distance to which these stars can be resolved at 3 mas resolution; the nearby hot supergiants with winds larger than 3 mas; three Be stars with disks that can be resolved; and the general characteristics of X-ray binaries. Studies of hot stars which can not be done at 3 mas are listed.
