Charles Hackmore was Manticoran citizen and an officer in the Royal Manticoran Navy.

In 1903 PD, he held the rank of Lieutenant Commander and served as chief engineer aboard HMS Apollo.

In the aftermath of the Battle of Blackbird, Lt. Commander Hackmore served as the Apollo's astrogation officer after Lieutenant Androunaskis was killed. On order from Commander Alice Truman, he took the safety interlocks off Apollo's engines to shave twenty-five to thirty hours off their transit time. He was very upset about Commander Truman's action, but understood her decision. (HH2)
