  We consider supersymmetry breaking models in which the MSSM is extended to
include an additional chiral adjoint field for each gauge group with which the
the MSSM gauginos acquire Dirac masses. We investigate a framework in which the
Standard Model gauge fields propagate in the bulk of a warped extra dimension
while quarks and leptons are localized on the ultraviolet brane. The adjoint
fields are localized on the infrared brane, where supersymmetry is broken in a
hidden sector. This setup naturally suppresses potentially large flavor
violating effects, while allowing perturbative gauge coupling unification under
SU(5) to be realized. The Standard Model superpartner masses exhibit a
supersoft spectrum. Since the soft scalar masses are generated at very low
scales of order the gaugino masses these models are significantly less
fine-tuned than other supersymmetric models. The LSP in this class of models is
the gravitino, while the NLSP is the stau. We show that this theory has an
approximate R symmetry under which the gauginos are charged. This symmetry
allows several possibilities for experimentally distinguishing the Dirac nature
of the gauginos.
