This is actually by design. There are several different classes of starship at present:
- Raid Starship (includes Raid, Leech, Stealth Leech line)
- Fleet Starship (includes Light and Flagship)
- Alien Starship (Zenith and Spire)
- Dreadnought (all three from the dreadnought line)
- Bomber Starship (all four from the bomber starship line)
- Cloaker Starship (all three from the cloaker line)
The galaxy map intel summary doesn't show ship names in general, but rather shows ship lines. Some of the bigger, more esoteric ships have a line all of their own (raid starship, etc), but others are just grouped (command station, guard post, heavy defense, etc).
