  We study a set of asymmetric deformations of non-critical superstring
theories in various dimensions. The deformations arise as Kaehler and complex
structure deformations of an orthogonal two-torus comprising of a parallel and
a transverse direction in the near-horizon geometry of NS5-branes. The
resulting theories have the following intriguing features: Spacetime
supersymmetry is broken in a continuous fashion and the masses of the lightest
modes are lifted. In particular, no bulk or localized tachyons are generated in
the non-supersymmetric vacua. We discuss the effects of these deformations in
the context of the holographic duality between non-critical superstrings and
Little String Theories and find solutions of rotating fivebranes in
supergravity. We also comment on the generation of a one-loop cosmological
constant and determine the effects of the one-loop backreaction to leading
order.
