  We investigate the viability of F-term uplift in heterotic M-theory. With
this aim we explore a natural ingredient of heterotic compactifications, namely
vector bundle moduli. It is shown that it is generically possible to obtain
stable de Sitter vacua with broken supersymmetry provided the little Kahler
potential and the prefactors of the non-perturbative superpotential are
suitably tuned. An additional requirement is the existence of non-trivial gauge
instantons both at the visible and hidden sectors. This is illustrated with
analytical and numerical examples.
