- There were no closeup shots of the Hood in TOS: "The Ultimate Computer". Star Fleet Technical Manual gives the registry as NCC-1707, while Greg Jein's numbering has it as NCC-1703.
In 2268, the Hood participated in a fleet war games exercise. This exercise put four starships against the M-5 controlled USS Enterprise (NCC-1701). The M-5 malfunctioned, causing the Enterprise to fire full-powered phasers at the minimally-defended Hood, severely damaging the ship. (TOS: "The Ultimate Computer")
- It remains unclear if this Hood was able to be reconstructed and reused, or if the damage was too widespread for repairs to be made. It also remains unclear if her crew survived.
