  In this paper we investigate the Proca-field in the framework of Loop Quantum
Gravity. It turns out that the methods developed there can be applied to the
symplectically embedded Proca-field, giving a rigorous, consistent,
non-perturbative quantization of the theory. This can be achieved by
introducing a scalar field, which has completely different properties than the
one used in spontaneous symmetry breaking. The analysis of the kernel of the
Hamiltonian suggests that the mass term in the quantum theory has a different
role than in the classical theory.
