  Optomechanical arrays are a promising future platform for studies of
transport, many-body dynamics, quantum control and topological effects in
systems of coupled photon and phonon modes. We introduce disordered
optomechanical arrays, focusing on features of Anderson localization of hybrid
photon-phonon excitations. It turns out that these represent a unique
disordered system, where basic parameters can be easily controlled by varying
the frequency and the amplitude of an external laser field. We show that the
two-species setting leads to a non-trivial frequency dependence of the
localization length for intermediate laser intensities. This could serve as a
convincing evidence of localization in a non-equilibrium dissipative situation.
