Blazon (Heraldic description) On a blue field: A ram in the act of butting, proper.

------: One who assaults or assails an opponent. The butting Ram in the design is an illustration of this act. The original design suggested by the ship’s officers depicted a stylised seahorse, having the head and neck of a horse, the body and tail of a griffon with feathered wigs and two hind legs with talons. Volant, ready to dive. It also carried the unofficial motto “Oppugnare, vincere est” – "Attack to conquer”. A bronze cast of this design was made by her builder and was displayed on the quarterdeck until the official design was approved in 1943.
