In this paper we study the spectra of glueballs on the Klebanov-Strassler background and its extension to the baryonic branch. We numerically calculate the mass spectrum of glueballs from the spin 2 ''gravity'' multiplet, which contains the traceless part of the stress-energy tensor and the transverse part of the U(1) -current. The mass spectra of the corresponding fluctuations in supergravity coincide due to supersymmetry, which is manifest in the effective five-dimensional theory through a Supersymmetric Quantum Mechanics transformation. We show that the glueball spectra grow as m n 2 Un 2 for large values of the baryonic branch parameter U.
