Abstract
A simple, KKLT-like construction of de Sitter vacua in type IIA string theory is presented in an STU model with guidance from string theory U-duality and with an uplifting anti-D6-brane. In four dimensions the model is reduced to supergravity with three chiral multiplets, namely , and , as well as one nilpotent multiplet representing the anti-D6-brane.
