Argent a kingfisher proper holding a trident in bend points upward Or.
(Glossary of Heraldic Terms)
In honour of the City of Halifax, the ship's badge incorporates the principle feature of the city's flag, a kingfisher. The kingfisher is holding the trident of Neptune, who was considered in Greek mythology to be Lord of all the seas. Indirectly, this conveys the navy's service on the seven seas and willingness to serve beyond the equator.
