We present initial results from two Chandra/ACIS observations of the Vela ``Bullet D'' region. The Bullet D region is a bright feature which protrudes beyond the main blast wave on the east side of the remnant. It has been suggested that the feature is a fragment of supernova ejecta which is just now pushing beyond the blast wave. An alternate explanation is that the feature is a ``break-out'' of the shock in which inhomogeneities in the ambient medium cause the shock to be non-spherical. We intend to use the imaging and spectral capabilities of the Chandra/ACIS instrument to distinguish between these competing explanations.
