  We study the neutrino oscillation physics performance of the Long-Baseline
Neutrino Experiment (LBNE) in various configurations. In particular, we compare
the case of a surface detector at the far site augmented by a near detector, to
that with the far site detector placed deep underground but no near detector.
In the latter case, information from atmospheric neutrino events is also
utilized. For values of \theta_{13} favored by reactor experiments and a 100
kt-yr exposure, we find roughly equivalent sensitivities to the neutrino mass
hierarchy, the octant of \theta_{23}, and to CP violation. We also find that as
the exposure is increased, the near detector helps increase the sensitivity to
CP violation substantially more than atmospheric neutrinos.
