An Abelian 2-form theory that maintains gauge-invariance despite having a mass is considered in 3+1 dimensions. Though this mass owes to a non-local term the corresponding classical equations of motion are completely local and subjected to proper gauge fixing, yielding 3 massive degrees of freedom. Subsequently, consistent Dirac brackets could be constructed for this system that agreed with the subsequently obtained quantization under the non-covariant gauge condition. The covariant gauge quantization reproduced the same spectrum following the dissociation of a spurious massless mode from the physical vector space. Moreover, a path-integral treatment of the theory saw ghosts decoupling and proper BRST transformations were obtained. This 2-form field mediates a screened interaction of Yukawa-type that mimics the Meisner effect when topologically coupled to a fermion current.
