Abstract 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 $$mathcal {N}=2$$ N=2 supergravity Double T Barrel Saddle Set coupled with one vector multiplet associated with 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 $$mathcal {N}=1$$ N=1 in four dimensions.

Interest in the linear dilaton model has lately been revived in the context of the clockwork mechanism, which has recently been proposed as a T-shirt new source of exponential scale separation in field theory.
