NGC 7673 is a unique local starburst galaxy with a much higher star formation rate than either M82 or the Antennae Galaxies, and yet is virtually unobserved in X-rays. 0.1 count/sec is expected in our proposed 60 ksec Chandra observation -- mostly in the form of soft diffuse thermal emission, and a population of High Mass X-ray Binaries that will be mostly resolved into 40 ultraluminous sources. Analysis of these components contribute to our understanding of the X-ray properties of starbursts and serves as a useful analog for the compact star forming galaxies and protogalaxies that dominate the overall star formation in the universe. As such, NGC 7673 is a keystone for locally calibrating the relation between star formation rate and hard X-ray luminosity.
