We classify rank two vector bundles on a given del Pezzo threefold of degree four whose projectivizations are weak Fano into seven cases. We also give an example for each of these seven cases.

We classify rank two vector bundles on a del Pezzo threefold X of Picard rank one whose projectivizations are weak Fano. We also investigate the moduli spaces of such vector bundles when X is of degree five, especially whether it is smooth, irreducible, or fine.
