Given a dihedral 2-groupPof order at least 8, we classify the splendid Morita equivalence classes of principal 2-blocks with defect groups isomorphic toP. To this end we construct explicit stable equivalences of Morita type induced by specific Scott modules using Brauer indecomposability and gluing methods; we then determine when these stable equivalences are actually Morita equivalences, and hence automatically splendid Morita equivalences. Finally, we compute the generalised decomposition numbers in each case.
