We present new results from a recent 220-ks Chandra observation of the galactic supernova remnant (SNR) W49B. W49B has several unique morphological and spectral features which are not found in other SNRs: it is the only SNR with large-scale segregation of its nucleosynthetic products, its X-ray spectrum is suggestive of rapid cooling uncommon in SNRs, and it is the only core-collapse SNR to date with detected lines from the heavy elements chromium and manganese. We have performed detailed X-ray morphological and spatially-resolved spectroscopic analyses of this deep observation, and we will highlight the preliminary findings related to the physical conditions and explosive origin of W49B.
