Abstract
ALMA is a millimeter/submillimeter interferometer currently under constuction at 5000m altitude in northern Chile. When completed in 2012, it will provide more than an order of magnitude increase in sensitivity, resolution as well as image fidelity compared with existing facilities. This will enable significant breakthroughs in many areas of astronomy, including the study of hot stars. The capabilities of ALMA are described, along with some of the potential areas of impact on hot star research.
