N2 - The construction is given for gauged N = 8 supergravity in five dimensions with gauge group SU(3,1). It is shown that this theory has an additional SU(2) global symmetry as well as a local composite USp(8) gauge symmetry. The scalar potential has a critical point which breaks the gauge symmetry down to SU(3)×U(1) and the supersymmetry down to N = 2, with the massless gravitinos transforming in a doublet of the global SU(2). The cosmological constant is zero, allowing compactification on a circle down to four dimensions. The relationship of this theory to IIB superstrings and to N = 2 Yang-Mills-Einstein supergravity theories is discussed.
