  While the robustness of Hawking radiation in the presence of UV Lorentz
breaking is well-established, the Unruh effect has posed a challenge, with a
large literature concluding that even the low-energy restoration of Lorentz
invariance may not be sufficient to sustain this phenomenon. Notably, these
previous studies have primarily focused on Lorentz-breaking matter on a
conventional Rindler wedge. In this work, we demonstrate that considering the
complete structure of Lorentz-breaking gravity, specifically the presence of a
hypersurface orthogonal aether field, leads to the selection of a new Rindler
wedge configuration characterized by a uniformly accelerated aether flow. This
uniform acceleration provides a reference scale for comparison with the
Lorentz-breaking one, thus ensuring the persistence of the Unruh effect in this
context. We establish this by calculating the expected temperature using a
Bogolubov approach, and by analyzing the response of a uniformly accelerated
detector. We suggest that this resilience of the Unruh effect opens interesting
possibilities towards future developments for using it as a tool to constrain
Lorentz breaking theories of gravity.
