Hammer is a callsign for a Galactica Viper pilot serving aboard the battlestar after the end of the Cylon War.
When Galactica is boarded by the Annihilators, Hammer informs Cerberus and Ulysses fighter groups that Galactica's been boarded, before Galactica's weapons are used against one of the battlestars (Battlestar Galactica: Origins 6).
