  In this work we present the minimal supersymmetric extension of the
five-dimensional dilaton-gravity theory that captures the main properties of
the holographic dual of little string theory. It is described by a particular
gauging of $\mathcal{N}=2$ supergravity coupled with one vector multiplet
associated to the string dilaton, along the $U(1)$ subgroup of $SU(2)$
R-symmetry. The linear dilaton in the fifth coordinate solution of the
equations of motion (with flat string frame metric) breaks half of the
supersymmetries to $\mathcal{N}=1$ in four dimensions. The non-supersymmetric
version of this model was found recently as a continuum limit of a discretised
version of the so-called clockwork setup.
