Recognition Notes
The Hammerhead HMR-HDb is a 75-ton fighter flown in the fire-support role, where the HMR-HA served the attack mission. It replaces the HMR-HA's twin large lasers in the nose with a single Gauss rifle in the same position. The hull carries Ferro-Aluminum armor in place of the HMR-HA's Primitive Fighter plate, and heat sink count falls from 16 to 10 single heat sinks. Boeing Interstellar builds the type at Terra, with field refit work carried out at various other sites.
