Attention has been focused on the opportunities for precision cosmology using Type Ia supernovae discovered and followed on the LSST. Core collapse supernovae - Types II and Ib/c - will also be discovered in equal numbers with a redshift limit of z~0.9 for a typical Type II. The LSST will be able to measure precise stellar death rates for massive stars to this redshift. Coupled with spectroscopy, distances can be measured using the ``standard candle" method of Hamuy & Pinto (2002), and the Expanding Photosphere Method, allowing for an alternate method for measuring acceleration provided that the distance errors can be reduced from the present scatter of ~ 0.3mag. Finally, a large dataset of Type Ib/c supernovae can be used search for evidence of the class of supernovae responsible for GRBs, but whose axis of gamma emission is not aligned with the direction toward the Earth.
