We consider real AW*-algebras, that is, Kaplansky algebras over the field of real numbers. As in the case of complex von Neumann algebras and complex AW*-algebras, real AW*-algebras are classified in terms of types , , , , and . We prove that if the complexification of a real AW*-algebra A also is an AW*-algebra, then the types of A and M coincide.
