Using computer, we classify the unitals in the Desarguesian projective plane of order 16. We use computational methods based on analysis involving tactical decompositions to break symmetry, making a computer search feasible. We prove that all unitals in PG(2,16)PG(2,16) are known, namely, up to isomorphism, there are exactly two Buekenhout–Metz unitals (one of them the Hermitian curve).
